Periodized Aerobic Training between Thresholds Improves Submaximal Cardiorespiratory Parameters in Octogenarians.

BACKGROUND AND AIMS: The worldwide aging population is expanding, with more individuals living into their 80s. Physiological functions decline gradually with age, compounded by sedentary lifestyles. Incorporating physical activity into daily routine is crucial for maintaining independence. This study aimed to assess a periodized high-intensity aerobic training program (PEZO-BT) in octogenarians, focusing on submaximal ergospirometry effects. METHODS: A total of 48 non-frail octogenarian subjects (12 females, 36 males) were randomized into control and intervention groups. All subjects underwent submaximal cardiopulmonary exercise testing with gas analysis at baseline, stopping after the respiratory compensation point (RCP). Our intervention group completed a 14-week PEZO-BT aerobic training program. The outcomes were oxygen consumption at first ventilatory threshold (VO2AT), ventilatory efficiency slope (VE/VCO2), oxygen uptake efficiency slope (OUES), cardiorespiratory optimal point (COP), oxygen pulse change (ΔVO2/HR) from anaerobic threshold (AT) to respiratory compensation point (RCP), and power output at anaerobic threshold (POAT). RESULTS: Mixed ANOVA examined time and treatment effects. If significance emerged, post hoc t-tests were used to compare significances between groups. The homogeneity of variance was assessed using Levene's test. Chi-square tests compared ergospirometry criteria and ventilatory performance within groups. The mean differences at post intervention were significant in VO2AT (p < 0.001), VE/VCO2 (p < 0.001), ΔVO2/HR (p < 0.05), and POAT (p < 0.001), while OUES and COP were not significant (p > 0.05). However, clinical effects were observed in the entire intervention group. CONCLUSIONS: Training improved exercise capacity and workload. Overall, this periodic aerobic and high-intensity interval training (HIIT) program yielded significant improvements in cardiorespiratory fitness (CRF) in previously untrained octogenarians with and without comorbidities. The findings suggest implications for promoting long-term healthy aging.

Multicomponent Training in Progressive Phases Improves Functional Capacity, Physical Capacity, Quality of Life, and Exercise Motivation in Community-Dwelling Older Adults: A Randomized Clinical Trial.

OBJECTIVE: To evaluate the effect of a multicomponent progressive training program (MPTP) on functionality, quality of life (QoL) and motivation to exercise (EM) in a group of older adults (OA) of a community. METHODS: A total of 55 participants of 69.42 ± 6.01 years of age were randomized into two groups; experimental (EG:35) and control (CG:20), and subjected to 27 weeks of MPTP. Functionality (pre/post-intervention) was assessed using the Short Physical Performance Battery (SPPB), Time Up and Go (TUG), Walking While Talking Test (WWT), Manual Dynamometry (MD), Forced Expiratory Volume in the first second (FEV1), Sit and Reach (SR), Back Scratch (BS), and walk for 2 min (2 mST). QoL was assessed using the SF-36 questionnaire and EM using the BREQ-3. The Kolmogorov-Smirnov and Levene tests were applied. A two-way repeated measures ANOVA was applied. A significance level of p < 0.05 was accepted for all comparisons. RESULTS: The EG compared to the CG improved in SPPB (ΔEG/CG: 29.67%/p < 0.001), TUG (ΔEG/CG: 35.70%/p < 0.05), WWT (ΔEG/CG: 42.93%/p < 0.001), MD (ΔEG/CG: 20.40%/p < 0.05), FEV1 (ΔEG/CG: 21.37%/p < 0.05), BS (ΔEG/CG: 80.34%/p < 0.05), 2 mST (ΔEG/CG: 33.02%/p < 0.05), SF-36 (ΔEG/CG: 13.85%/p < 0.001), and Intrinsic Regulation (ΔEG/CG: 27.97%/p < 0.001); Identified by regulation (ΔEG/CG: 9.29%/p < 0.05). CONCLUSION: An MPTP improves functionality, QoL and EM, and is a safe and effective method for community OAs.

Relation between VT1, VT2, and VO2max with the Special Wrestling Fitness Test in Youth Wrestlers: A Short Report.

This study investigated the relationship between peak oxygen uptake and ventilatory threshold 1 (VT1) and 2 (VT2) with the Special Wrestling Fitness Test variables. Thirteen wrestlers (male: six; female: seven) of Olympic freestyle wrestling were assessed. The Pearson's correlation coefficient (p < 0.05) was used to establish the relationship between variables. A positive correlation was found between VT1 with throws in set B (r = 0.77; p = 0.002; 95%CI = 0.37-0.93), total throws (r = 0.73; p = 0.004; 95%CI = 0.30-0.91), heart rate recovery (r = 0.58; p = 0.036; 95%CI = 0.05-0.86), and test index (r = -0.60; p = 0.031; 95%CI = -0.86-0.07); between VT2 and throws in set B (r = 0.57; p = 0.043; 95%CI = 0.01-0.86); and between peak oxygen uptake with throws in set B (r = 0.77; p = 0.002; 95%CI = 0.39-0.93), throws in set C (r = 0.64; p = 0.02; 95%CI = 0.12-0.89), and total throws (r = 0.72; p = 0.006; 95%CI = 0.28-0.91). In conclusion, the peak oxygen uptake and ventilatory thresholds correlated with specific Special Wrestling Fitness Test variables.

Analysis of the public financial investment in elite sport in chile / Análise da contribuição financeira para o esporte de elite no chile / Análisis de la contribución financiera al deporte de élite en chile

Abstract Funding is one of the most controversial areas when analyzing the likelihood of performance in elite sports. In order to establish the level of funding available in this area, it was necessary to establish certain conceptual margins with respect to elite sport and to determine the different sectors of sport that fit the proposed conceptual definition. Using a non-experimental descriptive method, based on empirical research in sports sciences and a meta-analysis strategy secondary information available on various websites of public services of Chile, together with yearbooks and information requested from entities linked to elite sport, Secondary information was collected that allowed knowing the different lines of funding from each of the factors and sub-factors of pillar 1 of the SPLISS model, proposed by De Bosscher et al. (2006) for the achievement of elite sport achievement that was part of the study. In conclusion, it can be established that a permanent increase in funding does not guarantee performance in elite sports.

Association of physical activity, muscular strength, and obesity indicators with self-concept in Chilean children.

Introduction: Objectives: the present study examined the association of physical activity, muscular strength, and obesity indicators with self-concept in Chilean children. Methods: this cross-sectional study included 1078 Chilean children (mean age: 9.1 years [standard deviation: 1.1]; 598 boys). Physical activity was evaluated using the Physical Activity Questionnaire for Older Children. Upper and lower limb strength was evaluated using a digital dynamometer and standing long jump performance, respectively. The general strength index was calculated based on z-score values. Obesity indicators used were height, weight, body mass index, and body fat. The self-concept test was used to determine the academic, social, emotional, family, physical self-concept dimensions and total self-concept of children. Results: the mean total self-concept was 3.3 (standard deviation: 0.5). Physical activity was associated with academic (ß: 0.32; p = 0.03), social (ß: 0.24; p = 0.04), family (ß: 0.13; p = 0.01), physical (ß: 0.46; p = 0.01) self-concept dimensions and total self-concept (ß: 0.22; p = 0.01), regardless of sex and age. Upper limb strength and general strength index were negatively associated with academic self-concept dimensions (ß: -0.02; p = 0.01 and ß: -0.13; p = 0.02) and total self-concept (ß: -0.04; p = 0.01). Body weight and body mass index were negatively associated with academic (ß: -0.01; p = 0.01 and ß: -0.01; p = 0.02) and physical self-concept dimensions (ß: -0.03; p = 0.03). Conclusions: these findings suggest that physical activity is positively related with self-concept. Thus, physical activity and self-percept must be considered as an essential social cognitive perspective to provide suitable mental health in children.

Introducción: Objetivos: el presente estudio examinó la asociación de indicadores de actividad física, fuerza muscular y obesidad con el autoconcepto en niños chilenos. Métodos: este estudio transversal incluyó a 1078 niños chilenos (edad media: 9,1 años [desviación estándar: 1,1]; 598 niños). La actividad física se evaluó mediante el Physical Activity Questionnaire for Older Children. La fuerza de los miembros superiores e inferiores se evaluó utilizando un dinamómetro digital y el rendimiento en salto de longitud de pie. El índice de fuerza general se calculó en base a los valores de z-score. Los indicadores de obesidad utilizados fueron altura, peso, índice de masa corporal y grasa corporal. Se utilizó el test de autoconcepto para determinar las dimensiones académicas, social, emocional, familiar, físico y autoconcepto total. Resultados: la muestra total presento un autoconcepto promedio de 3,3 (desviación estándar: 0,5). La actividad física se asocio con autoconcepto académico (ß: 0,32; p = 0,03), social (ß: 0,24; p = 0,04), familiar (ß: 0,13; p = 0,01), físico (ß: 0,46; p = 0,01) y total (ß: 0,22; p = 0,01). La fuerza muscular de miembros superiores y el índice general de fuerza se asociaran negativamente con al autoconcepto académico (ß: -0,02; p = 0,01 y ß: -0,13; p = 0,02) y total (ß: -0,04; p = 0,01). Mientras que el peso corporal e índice de masa corporal se asociaron negativamente con autoconcepto académico (ß: -0,01; p = 0,01 y ß: -0,01; p = 0,02) y físico (ß: -0,03; p = 0,03). Conclusiones: estos hallazgos sugieren que la actividad física se relaciona positivamente con el autoconcepto. Así, la actividad física y la autopercepción deben ser consideradas como una perspectiva cognitiva social imprescindible para proporcionar una adecuada salud mental en los niños.

Anthropometric Indicators of the Cardiometabolic Risk, Muscle Strength, and Functional Capacity of Schoolchildren with Intellectual Disabilities during Lockdown in Chile.

Lockdown due to the COVID-19 pandemic has negatively impacted the social, psychological, and physical well-being of the world population. In the case of people with intellectual disabilities, the impact of lockdown on their physical condition and functionality is not completely clear. This study aimed to determine the effects of COVID-19 lockdown on the anthropometric indicators of cardiometabolic risk, muscle strength, and functionality on schoolchildren with intellectual disabilities. The sample was composed of 132 students of both sexes (n = 74 pre-lockdown; n = 58 lockdown) belonging to two special education centers from the Metropolitan Region of Santiago, Chile. Our results showed significant reductions (p ≤ 0.05) in absolute and relative handgrip strength, as well as in functionality, when comparing pre-lockdown and lockdown measurements, with a greater loss in girls than boys. The design and implementation of physical exercise programs centered on strength training are necessary for the physical and functional reconditioning of this population. These programs need to be implemented in special education centers considering the general well-being, quality of life and work needs of people with intellectual disabilities.

Sub Maximal Ergospirometry Parameters in Untrained Non-Frail Octogenarian Subjects.

Background and Objectives: The prevalence of chronic diseases increases with age, and in octogenarian elderly, a cardiorespiratory test with gas analysis is more effective in determining the risk of mortality than applying the conventional risk factors. Materials and Methods: 25 untrained non-frail octogenarian subjects (four men) performed a submaximal test with gas analysis, which was stopped after the second ventilatory threshold (VT2) was reached. The variables analyzed were oxygen consumption at the first threshold (VO2 VT1); ventilatory class (VE/VCO2); oxygen uptake efficiency slope (OUES); cardiorespiratory optimal point (COP); oxygen pulse difference between VT2 and VT1 (diff. VO2/HR VT2-VT1). Results: the variables were classified categorically based on cut-off points present in the literature, where the variable with the highest percentage of altered cases was dif. VO2/HR VT2-VT1 at 48%; followed by VO2 VT1 at 40%, OUES at 36%, COP at 32%, and VE/VCO2 at 24%. Chi-square analysis between the measured parameters defined that normal and altered variables were related to each other, except for the variable VE/VCO2 and OUES. Conclusions: it was found that the main altered variable was the oxygen pulse and the least altered variable was VCO2/VCO2; there was only a statistically significant difference in a pair of OUES vs. VE/VCO2 variables.

Lifestyle Habits and Health Indicators in Migrants and Native Schoolchildren in Chile.

In Chile, the migrant population has increased in the last years. Migrants adopt behaviors of this new culture, which can have an effect on their health. Contradictory results regarding differences between migrant and native children have been reported. The aim of this study was to explore the associations between nationality with health indicator and lifestyle habits among schoolchildren in Chile. A cross-sectional and observational study with a non-probabilistic sample was conducted in 1033 children (86.4% Chilean and 13.6% migrant) from second to fourth grade of seven public schools from low-income municipalities from the Metropolitan Region, Chile. Anthropometric measurements (weight, height, waist circumference, triceps and subscapular folds), handgrip strength, and standing long jump measurements, physical activity, self-esteem and food guidelines accomplishments were determined. Migrant children presented lower body mass index (BMI), Z-BMI, body fat% and waist circumference values; and higher handgrip strength, standing long jump, and more satisfactory compliance with food guidelines than natives (p < 0.05). No significant difference for physical activity and self-esteem was observed. In the adjusted models, migrants presented lower odds for overweight/obesity, risk of abdominal obesity, low handgrip strength and unsatisfactory food guidelines accomplishment in all models (p < 0.05). The nutritional and muscular fitness of migrant children was better than that of the Chilean ones.

Normative Reference Values for Handgrip Strength in Chilean Children at 8-12 Years Old Using the Empirical Distribution and the Lambda, Mu, and Sigma Statistical Methods.

ABSTRACT: Garcia-Hermoso, A, Cofre-Bolados, C, Andrade-Schnettler, R, Ceballos-Ceballos, R, Fernández-Vergara, O, Vegas-Heredia, ED, Ramírez-Vélez, R, and Izquierdo, M. Normative reference values for handgrip strength in Chilean children at 8-12 years old using the empirical distribution and the lambda, mu, and sigma statistical methods. J Strength Cond Res 35(1): 260-266, 2021-The aim of this study was 2-fold (a) to provide sex- and age-specific handgrip reference standards for Chilean children aged 8-12 years and (b) to compare the levels of handgrip strength of Chilean children with those of children from other countries. This cross-sectional study enrolled 2,026 schoolchildren (boys n = 1,334 and girls n = 692, mean age 10.18 [1.16] years old). Handgrip strength was measured using a hand dynamometer with an adjustable grip. Relative handgrip strength was calculated by dividing handgrip strength by body mass (handgrip strength kg per mass kg). Smoothed centile curves and tables for the 10th, 20th, 30th, 40th, 50th, 60th, 70th, 80th, and 90th centiles were calculated using Cole's lambda, mu, and sigma method. The results indicate that mean handgrip strength was greater among boys than girls. Handgrip strength peaked at 16.25 (5.03) kg in boys and 14.90 (4.32) kg in girls. In addition, relative handgrip strength peaked at 0.38 (0.08) in boys and 0.34 (0.07) in girls. Chilean children of both sexes scored higher than their South American counterparts from Colombia and Peru but showed lower handgrip strength than European and Australian children. Our results provide, for the first time, sex- and age-specific handgrip reference standards for Chilean children aged 8-12.9 years. These normative reference values could help identify the levels of handgrip strength that need attention to provide appropriate feedback and advice to children about how to best improve their overall physical fitness.

Association between Perceived Neighborhood Built Environment and Walking and Cycling for Transport among Inhabitants from Latin America: The ELANS Study.

PURPOSE: This study aimed to examine the associations of the perceived neighborhood built environment with walking and cycling for transport in inhabitants from Latin American countries. METHODS: This cross-sectional study involved 9218 participants (15-65 years) from the Latin American Study of Nutrition and Health, which included a nationally representative sample of eight countries. All participants completed the International Physical Activity Questionnaire-Long Form for measure walking and cycling for transport and the Neighborhood Environment Walkability Scale-Abbreviated. Furthermore, perceived proximity from home to public open spaces and shopping centers was assessed. RESULTS: Perceived land use mix-access (OR: 1.32; 95%CI: 1.16,1.50) and the existence of many alternative routes in the neighbourhood (1.09 1.01,1.17) were associated with higher odds of reporting any walking for transport (≥10 min/week). Perceived slow speed of traffic (1.88 1.82,1.93) and few drivers exceeding the speed limits (1.92; 1.86,1.98) were also related to higher odds of reporting any walking for transport. The odds of reporting any cycling for transport (≥10 min/week) were higher in participants perceiving more walking/cycling facilities (1.87 1.76,1.99), and better aesthetics (1.22 1.09,1.38). CONCLUSIONS: Dissimilar perceived neighborhood built environment characteristics were associated with walking and cycling for transport among inhabitants from Latin America.

Socio-Demographic Correlates of Total and Domain-Specific Sedentary Behavior in Latin America: A Population-Based Study.

PURPOSE: The aim of this study was to identify socio-demographic correlates of total and domain-specific sedentary behavior (SB). METHODS: Cross-sectional findings are based on 9218 participants (15-65 years) from the Latin American Study of Nutrition and Health. Data were collected between September 2014 and February 2015. Participants reported time spent in SB across specific domains. Sex, age, ethnicity, socioeconomic (SEL), and education level were used as sociodemographic indicators. RESULTS: Participants spent a total of 373.3 min/day engaged in total SB. Men, younger adults, other ethnicities, higher SEL and educational level presented higher total SB when compared with women, older adults, white/Caucasian, and low SEL and educational level. Men spent more time on the playing videogames (b: 32.8: 95% CI: 14.6;51.1) and riding in an automobile (40.5: 31.3; 49.8). Computer time, reading, socializing or listening to music was higher in younger participants (<30 years) compared with those ≥50 years in the total sample. Compared to the low SEL and educational level groups, middle (11.7: 5.7; 17.6) and higher (15.1: 5.3; 24.9) SEL groups as well as middle (9.8: 3.6; 15.9) and higher (16.6: 6.5; 26.8) education level groups reported more time spent reading. CONCLUSION: Socio-demographic characteristics are associated with SB patterns (total and specific) across Latin American countries.

The aim of the present study was to define and contrast a explicative model of the relationship between the variables of quality of life that make up the KIDSCREEN-52 questionnaire. METHODS: A total of 1641 Colombian university students aged between 17 and 18 years (17.69 + 0.490) participated in this research (61.2% males and 38.8% females) analyzing the dimensions of the KIDSCREEN-52 quality of life questionnaire. A model of structural equation was made and adjusted (χ2 = 118.021; DF = 6; p < 0.001; CFI = 0.953; NFI = 0.951; IFI = 0.954; RMSEA = 0.076). RESULTS: The analyzed dimensions of quality of life were related in a positive and direct way, except for the Parent Relationship and Family Life (Family L.) with Social Acceptance (Social A.), which were associated in a negative and indirect manner. CONCLUSIONS: The main conclusion of this investigation is that all dimensions of quality of life associate in a positive manner with the exception of Parent Relationship and Family Life (Family L.) which associated with Social Acceptance (Social A.). The qualities improve together, highlighting the idea that working on any of the areas that comprise quality of life will cause development of the remaining areas.

Physical Activity in Natural Environments Is Associated With Motivational Climate and the Prevention of Harmful Habits: Structural Equation Analysis.

BACKGROUND: Practicing physical activity in a natural environment has various benefits that make it an ideal setting to develop healthy behaviors and thereby diminish unhealthy habits. The objective of this study was to develop and verify an explicative model for motivational climate in sport, considering its potential influence on alcohol and tobacco consumption. METHODS: The study included 2273 adolescents from Granada (Spain), analyzing motivational climate (PMCSQ-2), alcohol consumption (AUDIT) and tobacco consumption (FTND). Multi-group structural equation modeling was conducted, yielding an excellent fit (χ2 = 168.170; gl = 32; p = 0.00; CFI = 0.972; NFI = 0.966; IFI = 0.972; RMSEA = 0.045). RESULTS: The main findings were: a negative relationship between task climate and alcohol consumption among students practicing physical activities in a natural environment; a positive relationship between ego climate and alcohol consumption among those practicing other types of physical activity; and a positive and direct relationship between alcohol and tobacco consumption, which was stronger among those who did not practice physical activity in a natural environment. CONCLUSION: We conclude that physical-sport activity practiced in nature is a key to acquiring healthy patterns characterized by intrinsic motivations in sport and lower consumption of harmful substances.

Validation of the ST3x1 Step Test as an estimator of peak VO2 in adults with cardiovascular risk factors / Validación del Test de Escalón ST3x1 como estimador del VO2 pico en adultos con factores de riesgo cardiovascular

Abstract Objective: To validate a tool for assessment and control of functional capacity and peak oxygen uptake. Methods: A transversal, correlational study was conducted in which 111 subjects (49.81 ± 11.16 years) were evaluated, their body mass index (BMI) was 31.42 ± 4.07, classified with moderate and high cardiovascular risk, according to the American Association of Cardiovascular and Pulmonary Rehabilitation. Its peak oxygen uptake was measured directly and also through the Step Test 3x1 (ST3x1). Results: Peak oxygen uptake in ST3x1 corresponded to 28.54 ml•kg-1•min-1 and direct measurement at 28.14 ml•kg-1•min-1, with a "strong positive" Pearson correlation r = 0.81, Student n/s p = 0.14 Conclusion: ST3x1 is a valid alternative to estimate peak oxygen uptake in the group studied, and can be used in mass public health physical activity programs.

Resumen Objetivo: Validar una herramienta de estimación y control de la capacidad funcional y el consumo de oxígeno pico. Materiales y métodos: Se realizó un estudio transversal, correlacional donde se evaluaron a 111 sujetos (49.81 ± 11.16 años), su índice de masa corporal (IMC) fue de 31.42 ± 4.07, clasificados con riesgo cardiovascular mediano y alto, según la American Association of Cardiovascular and Pulmonary Rehabilitation. Se midió su consumo pico de oxígeno en forma directa y también a través del Step Test 3x1 (ST3x1). Resultados: El consumo de oxígeno pico en ST3x1 correspondió a 28.54 mlŸkg -1 Ÿmin -1 y en la medición directa a 28.14 mlŸkg -1 Ÿmin -1, con una correlación de Pearson fuerte positiva r = 0.81, Student n/s p = 0.14. Conclusión: ST3x1 se presenta como alternativa para estimar el consumo de oxígeno pico en el grupo estudiado, pudiendo ser usado en programas masivos de actividad física en salud pública.
