Effectiveness of elastic band training and group-based dance on physical-functional performance in older women with sarcopenia: a pilot study.

BACKGROUND: Sarcopenia is a syndrome associated with aging that causes progressive loss of skeletal muscle mass and muscle function. In this pilot study, we compared the effectiveness of elastic band training regarding group-based dance on fat mass, fat-free mass, handgrip strength (HGS; dominant and non-dominant hand), leg strength, timed up-and-go (TUG) and walking speed in older women with sarcopenia. METHODS: This is a randomized controlled trial, single-blind, repeated measures of parallel groups (elastic band group: EBG, n = 21; group-based dance: GBD, n = 19), and a quantitative methodology. Three 60-minute sessions per week for 12 weeks were dedicated to the interventions with pre- and post-assessments. A two-factor mixed analysis of variance (ANOVA) model with repeated measures was performed to measure the group×time effect. RESULTS: A significant interaction revealed for fat-free mass (F1,16= 18.91; p < 0.001; EBG + 10.9% vs. GBD - 1.97%), HGS dominant hand (F1,16= 7.44; p = 0.014; EBG + 10.9% vs. GBD + 0.59%), HGS non-dominant hand (F1,16= 6.41; p = 0.022; EBG + 10.21% vs. GBD + 3.80%), leg strength (F1,16= 17.98; p < 0.001; EBG + 9.1% vs. GBD + 3.83%), TUG (F1,16= 7.52; p = 0.014; EBG - 14.7% vs. GBD - 1.0%) and walking speed (F1,16 = 6.40; p = 0.019; EBG - 7.6% vs. GBD - 4.35%) in favor of EBG. CONCLUSION: Elastic band training produces significantly greater responses on physical-functional performance regarding group-based dance in older women with sarcopenia. On the other hand, the EBG revealed a significant improvement in fat-free mass and upper and lower limb muscle strength, as well as a significant decrease time in TUG, and walking speed. Elastic band exercise is a safe, easy, affordable, and effective physical activity strategy, according to the findings.

Psychological Factors Predicting Sedentary Behavior of Older Adults: A Cross-Sectional Study in Brazil.

This cross-sectional study aimed to investigate the psychological factors that might predict the sedentary behavior of 654 older adults from the South Region of Brazil. The participants were evaluated by the International Physical Activity Questionnaire; Mini-Mental State Exam; Geriatric Anxiety Scale; and the scales Geriatric Depression, Purpose in Life, Perceived Stress, Rosenberg Self-Esteem, and Satisfaction with Life. Data analysis was conducted through Pearson correlation and multiple regression analysis (p < .05). No significant (p > .05) correlation was found between the sedentary behavior variables with self-esteem. Multiple regression analysis revealed that psychological variables explained 6% of the variance of sitting time during the week (R2 = .06; F = 11.546; p < .01). Depression showed a positive prediction (ß = -0.10; p = .040), while life satisfaction (ß = -0.16; p = .001) and purpose in life (ß = -0.10; p = .026) showed negative prediction. Psychological variables predicted only 3% of the variance of sitting time during the weekend (R2 = .03; F = 5.629; p < .01), showing that life satisfaction had significant (p = .007) and negative (ß = -0.13) association. Life satisfaction and purpose in life can be considered protector factors to sedentary behavior, while depression is a potentiating factor.

Does moderate-intensity continuous training result in greater total energy expenditure compared to high-intensity interval training?

Recently in the Journal of Sports Sciences, Schaun et al. published a study on the comparison of energy expenditure between high-intensity interval training and moderate continuous training performed in water. With this Letter to the Editor, we would like to comment on the methodological aspects that should be considered to analyze the results presented, as well as the conclusions. Abbreviations: CONT, moderate-intensity continuous training; EPOC, excess post-exercise oxygen consumption; HIIT, high-intensity interval training; VO2max, maximal oxygen consumption.

Effects of active exergames on physical performance in older people: an overview of systematic reviews and meta-analysis.

This overview assessed the available body of published peer-reviewed systematic reviews and meta-analyses related to the effects of active exergames compared with active/passive control on physical performance outcomes in older people. The methodological quality and certainty of evidence were assessed using PRISMA, AMSTAR 2, and GRADE. The protocol was registered in PROSPERO (code: CRD42023391694). The main outcomes indicate that 4,477 records, five systematic reviews, and 10 meta-analyses were included. The AMSTAR-2 reported six meta-analyses with high methodological quality, four moderate quality, two systematic reviews with low quality, and three very-low quality. Meta-analysis was performed on balance using the Berg Balance Scale (BBS) and Timed Up-and-Go (TUG) tests, on cardiorespiratory fitness using the 6-min walk test, and on upper and lower limbs muscle strength using the handgrip strength, knee extension, and 30-s chair stand tests. Significant differences in favor of the active exergames groups concerning active/passive groups were reported in BBS (SMD = 0.85; 95% CI = 0.12-1.58; I2 = 96%; p = 0.02), TUG (SMD = 1.44; 95% CI = 0.71-2.16; I2 = 97%; p < 0.0001), and 30-s chair stand test (SMD = 0.79; 95% CI = 0.33-1.25; I2 = 88%; p = 0.0008). However, no significant differences were reported in favor of the active exergames groups in 6-min walk (SMD = 0.93; 95% CI = -0.64 to 2.50; I2 = 95%; p = 0.24), handgrip strength (SMD = 0.67; 95% CI = -0.04 to 1.38; I2 = 84%; p = 0.06), and knee extension tests (SMD = 0.20; 95% CI = -0.05 to 0.44; I2 = 95%; p = 0.12) compared to active/passive control. However, it was impossible to perform a meta-analysis for the variables of walking speed as a fall risk due to the diversity of instruments and the small number of systematic reviews with meta-analysis. In conclusion, interventions utilizing active exergames have shown significant improvements in the static and dynamic balance and lower limb muscle strength of apparently healthy older people, compared to control groups of active/inactive participants, as measured by BBS, TUG, and 30-s chair stand tests. However, no significant differences were found in the 6-min walk, HGS, and knee extension tests. Systematic review registration: PROSPERO, CRD42023391694.

Impact of adapted taekwondo vs. multicomponent training on health status in independent older women: a randomized controlled trial.

This study, called the TKD and Aging Project, aimed to analyze and compare the effects of an adapted taekwondo program concerning multicomponent training on blood pressure, morphological variables, food consumption frequency, health-related quality of life (HRQoL), physical fitness, handgrip strength, and postural balance in independent older women. A randomized controlled trial study was conducted with parallel groups for 8 weeks (24 sessions of 60 min each), employing a double-blind design and incorporating repeated measures. Twenty-eight older women initially participated in the intervention. Three participants were excluded because they did not participate in the re-assessments. Thus, 14 older women from the adapted taekwondo group (TKD; age: 62.86 ± 2.38 years) and 11 from the multicomponent training group (MCT; age: 63.18 ± 1.94 years) participated in the final analysis. A two-factor mixed analysis of variance (ANOVA) model with repeated measures was performed to measure the time × group effect. The TKD showed significant improvements in the mental health (p = 0.024; ES = 0.91) and general health (p < 0.001; ES = 0.75) dimensions of the HRQoL, as well as in the chair stand (p = 0.001; ES = 1.18), arm curl (p < 0.001; ES = 2.10), 2-min step (p < 0.001; ES = 1.73), and chair sit-and-reach (p = 0.001; ES = 0.91) tests. Additionally, it showed a significant reduction in postural balance for the eyes-closed condition in the center of the pressure area (p = 0.021; ES = 0.89), mean velocity (p = 0.004; ES = 0.79), and mediolateral velocity (p < 0.001; ES = 1.26). However, the MCT showed significant increases in the general health (p = 0.013; ES = 0.95) dimension of the HRQoL and a significant reduction (p = 0.039; ES = 0.28) in the mediolateral velocity of postural balance for the eyes-closed condition. Multiple comparisons showed that the TKD scored significantly higher in the chair stand (p = 0.017; ES = 1.79), arm curl (p = 0.003; ES = 1.77), and 2-min step (p = 0.018; ES = 0.91) tests than the MCT. Compared to multicomponent training, taekwondo improves postural balance and provides better benefits in terms of physical fitness and HRQoL for older women. Therefore, it is possible to recommend it as a safe physical activity strategy, as long as it is well-dosed, since it showed high adherence to intervention in older women.

Body composition and cardiorespiratory fitness of overweight COVID-19 survivors in different severity degrees: a cohort study.

COVID-19 sequelae are varied, and whether they are temporary or permanent is still unknown. Identifying these sequelae may guide therapeutic strategies to improve these individuals' recovery. This prospective cohort aimed to assess body composition, cardiopulmonary fitness, and long-term symptoms of overweight individuals affected by COVID-19. Participants (n = 90) were divided into three groups according to the severity of acute COVID-19: mild (no hospitalization), moderate (hospitalization, without oxygen support), and severe/critical cases (hospitalized in Intensive Care Unit). We assessed body composition with a tetrapolar multifrequency bioimpedance, hemodynamic variables (heart rate, blood pressure, and peripheral oxygen saturation-SpO2) at rest, and the Bruce test with direct gas exchange. Two assessments with a one-year interval were performed. The most prevalent long-term symptoms were memory deficit (66.7%), lack of concentration (51.7%), fatigue (65.6%), and dyspnea (40%). Bruce test presented a time effect with an increase in the distance walked after 1 year just for severe/critical group (p < 0.05). SpO2 was significantly lower in the severe/critical group up to 5 min after the Bruce test when compared to the mild group, and diastolic blood pressure at the end of the Bruce test was significantly higher in the severe/critical group when compared to mild group (p < 0.05; for all comparisons). A time effect was observed for body composition, with increased lean mass, skeletal muscle mass, fat-free mass, and lean mass just for the severe/critical group after 1 year (p < 0.05). Cardiopulmonary fitness parameters did not differ among the groups, except for respiratory quotient with higher values for the severe/critical group when compared to itself after 1 year. All COVID-19 patients might present long-term sequelae, regardless of the acute disease severity. Reassessing and identifying the most prevalent long-term sequelae are essential to perform more precise health promotion interventions.

Eating disorders in weight-related therapy (EDIT): Protocol for a systematic review with individual participant data meta-analysis of eating disorder risk in behavioural weight management.

The Eating Disorders In weight-related Therapy (EDIT) Collaboration brings together data from randomised controlled trials of behavioural weight management interventions to identify individual participant risk factors and intervention strategies that contribute to eating disorder risk. We present a protocol for a systematic review and individual participant data (IPD) meta-analysis which aims to identify participants at risk of developing eating disorders, or related symptoms, during or after weight management interventions conducted in adolescents or adults with overweight or obesity. We systematically searched four databases up to March 2022 and clinical trials registries to May 2022 to identify randomised controlled trials of weight management interventions conducted in adolescents or adults with overweight or obesity that measured eating disorder risk at pre- and post-intervention or follow-up. Authors from eligible trials have been invited to share their deidentified IPD. Two IPD meta-analyses will be conducted. The first IPD meta-analysis aims to examine participant level factors associated with a change in eating disorder scores during and following a weight management intervention. To do this we will examine baseline variables that predict change in eating disorder risk within intervention arms. The second IPD meta-analysis aims to assess whether there are participant level factors that predict whether participation in an intervention is more or less likely than no intervention to lead to a change in eating disorder risk. To do this, we will examine if there are differences in predictors of eating disorder risk between intervention and no-treatment control arms. The primary outcome will be a standardised mean difference in global eating disorder score from baseline to immediately post-intervention and at 6- and 12- months follow-up. Identifying participant level risk factors predicting eating disorder risk will inform screening and monitoring protocols to allow early identification and intervention for those at risk.

Effectiveness of Adapted Taekwondo, Multi-Component Training and Walking Exercise on Health Status in Independent Older Women: Study Protocol for a Randomized Controlled Trial (TKD & Aging Project).

This study protocol aims to analyze and compare the effects of an adapted taekwondo program with respect to multi-component training and walking exercise on health status in independent older women. Secondarily, we analyze the variability of the inter-individual response and compare it according to the designated training system. The sample will consist of 64 women between 60 and 65 years, randomly assigned to experimental group 1 (n = 16; adapted taekwondo), experimental group 2 (n = 16; multi-component training), experimental group 3 (n = 16, walking exercise) or control group (n = 16; no intervention). The experimental groups will perform the designated training for three sessions (60 min per session) per week over 16-weeks, while the control group will not receive any treatment. The main outcome will provide information about (i) blood pressure, (ii) lipid profile, (iii) frequency of food consumption, (iv) body composition, (v) cognitive status, (vi) brain activity, (vii) health-related quality of life (HRQoL) and (viii) physical-functional fitness. Our hypothesis indicates that adapted taekwondo produces more significant effects and greater inter-individual responses in cognitive status, brain activity, HRQoL, and postural balance than the others training methods. If this intervention proves effective, it could be an alternative for older women.

Factors Associated with Poor Health-Related Quality of Life in Physically Active Older People.

This study aimed to associate morphological variables and physical fitness with health-related quality of life (HRQoL) in physically active older people. A cross-sectional study was carried out that evaluated 470 older people (89.57% female) with a mean age of 70.13 ± 6.57 years, residing in two regions of Chile. Morphological variables (body weight, bipedal height, waist circumference, body mass index, and waist to height ratio), physical fitness through the Senior Fitness Test protocol, and HRQoL using the SF-36 questionnaire were obtained. Logistic regression analysis was used to identify risk factors between morphological variables and physical fitness associated with HRQoL. The main results indicated that overweight (OR = 1.52; p = 0.034), a waist circumference with risk (OR = 1.56; p = 0.021), poor performance in the back scratch tests (OR = 1.02; p = 0.008) and timed up-and-go (OR = 1.19; p = 0.040) increased the probability of having a low general HRQoL. Also, the low performance of chair stand and arm curl tests was associated with poor physical and social dimensions of HRQoL (p < 0.05). In conclusion, a low HRQoL in physically active older people is associated with both morphological and physical fitness factors.

Effectiveness of Olympic Combat Sports on Balance, Fall Risk or Falls in Older Adults: A Systematic Review.

This systematic review and meta-analysis aimed to assess the available body of published peer-reviewed articles related to the effects of Olympic combat sports (OCS), compared with active/passive controls, on balance, fall risk, or falls in older adults. The TESTEX and GRADE scales assessed the methodological quality and certainty of the evidence. The protocol was registered in PROSPERO (code: CRD42020204034). From 1496 records, eight studies were included, involving 322 older adults (64% female; mean age = 71.1 years). The TESTEX scale revealed all studies with a score ≥ 60% (moderate-high quality). The GRADE scale indicated all studies with at least some concerns, up to a high risk of bias (i.e., was rated very low). Meta-analyses were planned, although the reduced number of studies precluded its incorporation in the final manuscript. Only two from six studies that assessed balance found improvements after OCS compared to controls. No differences were found between OCS vs. control groups for fall risk or falls. The available evidence does not allow a definitive recommendation for or against OCS interventions as an effective strategy to improve balance and reduce the fall risk or falls in older adults. Therefore, more high-quality studies are required to draw definitive conclusions.

No effect of combined tele-exercises and nutritional coaching on anthropometric, body composition or exercise capacity outcomes in overweight and obese women: a randomized clinical trial.

Introduction: Background: we aimed to investigate the isolated effect of tele-exercises (TE) and their combined effect with nutritional coaching (NC) on health-related parameters of overweight and obese individuals. Methods: forty-one overweight (body mass index ≥ 25 kg/m2) and obese (body mass index ≥ 30 kg/m2) women were randomly assigned to the experimental groups: TE (n = 20) or TE+NC (n = 21). TE was applied 3 days/week in both groups, while TE+NC also received NC 1 day/week. Anthropometric, body composition, and exercise capacity-related outcomes, quality of life, and eating behavior were assessed before and after 8 weeks of the intervention. Results: a significant main time effect (p < 0.01) was detected for flexibility, isometric muscle strength and dynamic muscle endurance, but no main group effect was noted (p > 0.05). On the other hand, neither a significant main time nor group effect (p > 0.05) was detected in the anthropometric and body composition measures, quality of life, or eating behavior. Similarly, no significant between-group difference was observed in the absolute or relative change analysis (all comparisons, p > 0.05). Conclusions: an 8-week TE program enhanced exercise capacity, but did not impact anthropometric or body composition-related outcomes. The combination of NC+TE did not have a clinical advantage in the management of overweight and obesity.

Introducción: Introducción: nuestro objetivo fue investigar el efecto aislado de los tele-ejercicios (TE) y su efecto combinado con el coaching nutricional (CN) sobre los parámetros relacionados con la salud de las personas con sobrepeso y obesidad. Métodos: cuarenta y una mujeres con sobrepeso (índice de masa corporal ≥ 25 kg/m2) y obesas (índice de masa corporal ≥ 30 kg/m2) fueron asignadas aleatoriamente a los grupos experimentales: TE (n = 20) o TE+CN (n = 21). La TE se aplicó 3 días/semana en ambos grupos, mientras que el grupo TE+CN también recibió NC 1 día/semana. Se evaluaron los resultados antropométricos, la composición corporal y la capacidad de ejercicio, la calidad de vida y la conducta alimentaria antes y después de 8 semanas de intervención. Resultados: se detectó un efecto de tiempo principal significativo (p < 0,01) para la flexibilidad, la fuerza muscular isométrica y la resistencia muscular dinámica, pero no se observó ningún efecto de grupo principal (p > 0,05). Por otro lado, no se detectó ningún efecto de tiempo principal ni de grupo significativo (p > 0,05) en las medidas antropométricas y de composición corporal, calidad de vida o conducta alimentaria. De manera similar, no se observaron diferencias significativas entre los grupos en el análisis del cambio absoluto o relativo (todas las comparaciones, p > 0,05). Conclusiones: un programa de TE de 8 semanas mejoró la capacidad de ejercicio pero no afectó los resultados antropométricos o relacionados con la composición corporal. La combinación de CN + TE no obtuvo ninguna ventaja clínica en el manejo del sobrepeso y la obesidad.

Warm-Up and Handgrip Strength in Physically Inactive Chilean Older Females According to Baseline Nutritional Status.

This study aims to analyze the effect of different types of warm-ups on handgrip strength (HGS) in physically inactive older females. Secondarily, it aims to compare HGS according to their baseline nutritional status. A randomized crossover trial study was conducted with 44 physically inactive older females distributed into normal weight (n = 12, BMI = 23.9 ± 3.2 kg/m2), overweight (n =16, BMI = 27 ± 4.7 kg/m2) and obese (n = 16, BMI = 31.6 ± 5.3 kg/m2), who participated in three warm-up conditions (static stretching condition, SSC; elastic band condition, EBC; and therapeutic compression ball condition, TCBC) and one control condition (CC, no warm-up). All participants performed the four randomized conditions with recovery within 72 h. A significant decrease (p < 0.05) in HGS for the dominant and non-dominant hands was observed when comparing SSC vs. CC. In contrast, comparing the warm-up conditions according to the baseline nutritional status, statistically significant differences (p < 0.05) were only reported in the obese group in the dominant and non-dominant hand in favor of CC concerning SSC. In conclusion, warm-up with static flexibility led to a decrease in HGS in physically inactive older females. Only the obese group exhibited this result when analyzed by nutritional status.

[Relationship between vigorous physical activity and body composition in older adults]. / Relación entre la actividad física vigorosa y la composición corporal en adultos mayores.

INTRODUCTION: Objective: the objective of the present study was to analyze the relationship between vigorous physical activity and body composition in older people who attend primary care centers. Material and methods: this study is characterized by being a descriptive, cross-sectional epidemiological study in 654 older adults (288 men and 366 women), most of them between 60 and 69 years of age (59 %), attending primary care centers in the city of Maringá, Brazil. The participants were evaluated using the International Physical Activity Questionnaire (IPAQ), anthropometric measurements, and a sociodemographic questionnaire to characterize the sample. Results: older adults who practice physical activities in primary care centers with vigorous intensity are associated with lower abdominal circumference, waist, hip, quadriceps, and calf measurements when compared to older people with low or moderate levels of physical activity. Conclusions: the practice of vigorous physical activity is related to low body perimeters (abdominal, hip, waist, calf) in older adults who attend primary care centers.

INTRODUCCIÓN: Objetivo: el objetivo del presente estudio fue analizar las relaciones entre la actividad física vigorosa y la composición corporal en personas mayores que asistían a centros de atención primaria. Material y métodos: este estudio se caracteriza por ser un estudio epidemiológico descriptivo y transversal de 654 adultos mayores (288 hombres y 366 mujeres), la mayoría de ellos de 60 a 69 años (59 %), que asistían a centros de atención primaria en la ciudad de Maringá, Brasil. Los participantes fueron evaluados con el Cuestionario Internacional de Actividad Física (IPAQ), mediciones antropométricas y un cuestionario sociodemográfico para caracterizar la muestra. Resultados: los ancianos que practican actividad física en los centros de atención primaria con intensidad vigorosa presentan mediciones más bajas de circunferencia abdominal, cintura, cadera, cuádriceps y pantorrilla en comparación con las personas mayores que practican actividad física de baja a moderada intensidad. Conclusiones: la práctica de actividad física vigorosa está relacionada con bajos perímetros corporales (abdominal, cadera, cintura, pantorrilla) en las personas adultas mayores atendidas en centros de atención primaria.

Effects of Olympic Combat Sports on Older Adults' Health Status: A Systematic Review.

The aim of this systematic review was to analyse the studies centered on the effects of Olympic combat sports (OCS [i.e., boxing, fencing, judo, karate, taekwondo, wrestling]) on older adults' physical-functional, physiological, and psychoemotional health status. The review comprised randomised-controlled trials with OCS interventions, including older adults (≥60 years), and measures of physical-functional, physiological, and/or psychoemotional health. The studies were searched through SCOPUS, PubMed/MEDLINE, Web of Science, PsycINFO, and EBSCO databases until 5 January 2021. The PRISMA-P and TESTEX scales were used to assess the quality of the selected studies. The protocol was registered in PROSPERO (code: CRD42020204034). Twelve OCS intervention studies were found (scored ≥ 60% for methodological quality), comprising 392 females and 343 males (mean age: 69.6 years), participating in boxing, judo, karate, and taekwondo. The qualitative analysis revealed that compared to controls, OCS training improved muscle strength, cardiorespiratory capacity, agility, balance, movement, attention, memory, mental health, anxiety, and stress tolerance. Meta-analysis was available only for the chair stand test, and an improvement was noted after OCS training compared to control. In conclusion, OCS interventions improves older adults' physical-functional, physiological, and psychoemotional health. Our systematic review confirms that OCS training has high adherence (greater than 80%) in older adults.

Sports and Functional Training Improve a Subset of Obesity-Related Health Parameters in Adolescents: A Randomized Controlled Trial.

To investigate the effects of two different modes of physical activity on body composition, physical fitness, cardiometabolic risk, and psychological responses in female adolescents participating in a multi-disciplinary program. The 12-week randomized intervention included 25-adolescents with overweight divided into two groups: sports practice-SPG and functional training-FTG. The SPG intervention was divided into three sports: basketball, handball, and futsal. SPG participants performed one sport 3-times/week, over the course of 1 month. The FTG performed concurrent exercises 3-times/week. This study was registered in Clinical Trials Registry Platform under number: RBR-45ywtg and registered in Local Ethics Committee number: 2,505.200/2018. The intensity of physical exercises-PE was matched between groups by the rating of perceived exertion. The primary outcome was body composition, and secondary outcomes were physical fitness, cardiometabolic risk, and psychological responses. There was a significant time-effect for body mass, body mass index, and low-density lipoprotein (LDL-c), all being reduced. There were increases over time for musculoskeletal mass, aerobic fitness, and high-density lipoprotein (HDL-c) (p < 0.05). There was a group time interaction with body fat percentage being lower post-intervention in the SPG (p < 0.05). No significant differences were observed for the other variables. Both physical activity models were effective in improving a subset of obesity-related health parameters. The findings should be extended by further investigation using more sophisticated measures of energy expenditure.

Group Nutrition Counseling or Individualized Prescription for Women With Obesity? A Clinical Trial.

Background: This study investigates the effects of group counseling vs. individual dietary prescription on physical, nutritional, and mental health in overweight or obese women. Methods: Seventy-four women aged 40-59 years with body mass index ≥ 25 kg/m2 were randomized into 2 intervention arms: group nutrition counseling (GNC) or individualized nutrition prescription (INP). Twenty-seven women completed the 12-week intervention protocol. The GNC received counseling once a week and the INP received an individualized prescription once a month. All participants attended physical exercise sessions 3 times a week following the same protocol. Body mass, body mass index, fat mass, body fat percentage, lean mass, lipid profile, hemoglobin A1c, insulin and liver transaminases were measured pre- and post-intervention in both arms. A 3 day food record was applied to calculate the intake of calories, carbohydrates, proteins, and lipids. Body image dissatisfaction, level of anxiety, self-esteem measure and pathological eating attitudes were measured. Results: Both dietary interventions decreased body mass, body mass index, fat mass, body fat percentage, total caloric intake, carbohydrates, proteins, lipids, body dissatisfaction, anxiety, and saturated and polyunsaturated fats (p < 0.05). Lean mass, metabolic variables, self-esteem and pathological eating attitudes remained unchanged (p > 0.05). Conclusion: Both nutritional interventions combined with concurrent exercise were effective to improve anthropometrics, body composition, food intake, and some mental health parameters. We suggest that the choice of nutritional intervention (GNC or INP) could be based on the participants preference, considering the adherence and satisfaction, to promote health and quality of life.

Effects of the Order of Physical Exercises on Body Composition, Physical Fitness, and Cardiometabolic Risk in Adolescents Participating in an Interdisciplinary Program Focusing on the Treatment of Obesity.

The main objective of this study was to investigate the effects of the order of physical exercises on body composition, physical fitness, and cardiometabolic risk in adolescents participating in an interdisciplinary program focusing on the treatment of obesity. The final 12-week analyses involved 33 female adolescents who were split into two groups of concurrent training (CT): resistance plus aerobic training and aerobic plus resistance training, with equalization performed in all physical exercises. The only difference between the two groups was the order in which the exercises were performed. The results showed reductions in fat mass, body fat, and waist circumference, as well as increases in musculoskeletal mass and resting metabolic rate (p < 0.05) following the multiprofessional intervention period. However, no significant differences were observed in regard to body mass, body mass index, neck circumference, or arm circumference (p > 0.05). Maximal isometric strength and maximal oxygen consumption showed significant increases after the intervention period (p < 0.05). There were reductions in insulin, HOMA-IR, total cholesterol, triglycerides, and low-density lipoproteins (p < 0.05), and an interaction within the resistance plus aerobic training group showed lower values for triglycerides when compared to itself (p = 0.002). No difference was found in fasting glycemia for either group (p > 0.05). It is worth noting that the equalization training variables presented no differences between the two groups (p > 0.05). Based on these results, both CT methods were found to be effective in promoting health parameters in overweight and obese female adolescents, and triglyceride values decreased more in the resistance plus aerobic group. Future studies with larger samples and feeding control should be conducted to confirm or refute our findings.

Proposal of a normative table for body fat percentages of Brazilian young adults through bioimpedanciometry.

Identification of the body fat (BF) percentage allows health professionals to detect healthy or risky patterns in a population. However, no studies have elaborated BF cutoff points using the bioelectrical impedance method in young Brazilian adults. Thus, the objective of the present study was to elaborate normative tables for BF in Brazilian men and women (sedentary and physically active) between 18 and 39 years of age. A total of 3,111 adults (958 men and 2,153 women) were evaluated using bioimpedance measurements with the InBody 520 device. The data were distributed normally and divided into percentiles (P3, P10, P25, P50, P75, P90, and P97). The following values were observed: for men: P3=8.9%-12.5%; P10=12.6%-17.5%; P25=17.6%-25.3%; P50=25.4%-35.1%; P75=35.2%-43.0%; P90=43.1%-49.4% and P97=49.5%; for women: P3=18.7%-23.1%; P10=23.2%-28.7%; P25=28.8%-35.7%; P50=35.8%-42.9%; P75=43.0%-49.1%; P90=49.2%-52.1% and P97≥52.2%. These percentiles can be used to classify the adiposity of sedentary and physically active individuals evaluated by bioimpedanciometry.

Change in the motivation pattern of adolescents before and after participation in a multidisciplinary health promotion program
