RESUMO

This study aims to assess the potential benefits and barriers of Move to Flow (MtF), a nature-based physical activity (PA) programme structured in two levels that include movements related to the animal, vegetal, and inert nature. A questionnaire was applied to 133 participants from Spain, Latvia, and Serbia. The instrument was structured in the following sections: socio-economic variables; sports participation; and health and physical condition perception. In addition, the Exercise Benefits and Barriers Scale (EBBS), which assesses these aspects on the physical, psychological, and social levels, was included. Results showed that men aged 36-50 obtained the highest total and benefit scores, while women and the youngest scored higher in barriers. Data analysis shows associations between weekly engagement in physical activity and intensity (p < 0.001) and the perceived benefits of MtF. In the case of intensity, it is the same with barriers (p < 0.001). Similarly, there is an association between benefits and barriers and perceived health status (p < 0.001) and physical condition (p < 0.001). Furthermore, positive correlations were found in MtF between PA frequency, intensity, and health and physical condition (r = 0.755). In conclusion, this study has demonstrated MtF's value as a cost-effective tool that empowers people to take an active role in improving their overall health and well-being.

RESUMO

Serve and return of the serve are among the most critical technical-tactical factors influencing performance in table tennis (TT). The present study aimed to analyse sex differences in the spatial distribution of serve and serve-return in elite TT players. A total of 48 elite TT players (men: n = 24; women: n = 24) participated in the investigation. A total of 24 matches were recorded and examined, analysing 1,177 plays and 5,319 strokes in the men's competition and 950 games and 5,097 strokes in the women's competition. Technical actions were analysed using an observation tool validated by two expert TT coach with a high level of agreement (K > 0.80). Men distributed their serves over zones 1 and 2 of the table, while women more frequently selected zone 5 (p < 0.05). In men, 30.1% of the serves were near the net, 63.6% in the middle zone of the table and 6.2% in the end zone of the table, while in women, these values were 10.9%, 67.2%, and 21.8%, respectively. As for the technique of the serve-return depending on the zone of the service, in men the action of the cut from zone 1 and 2 predominated, while in women this technique was more frequent from zone 5 (p < 0.05). On the other hand, the serve-return with the flip technique in zone 1, 3 and 4 was more frequent in men (p < 0.05). As for the return of the serve with the topspin technique, there were differences in zone 3, being more frequent in men (p < 0.05). Finally, the serve return with cut and defensive serve-return techniques in zones 3, 4, 5, and 6 were more frequent in women (p < 0.05). There are differences between sexes in service and return of serve actions during a match in elite players.

RESUMO

This study aimed to assess the physical fitness and upper body asymmetries of young padel players aged between 13 and 16 years and to determine the possible differences between genders and categories. A total of 60 padel players were divided into four groups: under-14 male (n = 15; age: 13.75 ± 0.45 years; height: 1.64 ± 0.07 m; weight: 54.7 ± 8.3 kg), under-14 female (n = 15; age: 13.75 ± 0.44 years; height: 1.60 ± 0.05 m; weight: 51.5 ± 6.0 kg), under-16 male (n = 15; age: 15.44 ± 0.51 years; height:1.71 ± 0.04 m; weight: 63.88 ± 6.2 kg) and under-16 female (n = 15; age:15.46 ± 0.52 years; height:1.63 ± 0.05 m; weight: 55.08 ± 3.6 kg). Handgrip strength, ischiosural flexibility, gestural speed of the dominant arm, vertical jump, cardiorespiratory capacity, lateral movement, lateral acceleration and reaction time were measured. Male players showed better results in manual grip strength, vertical jump power, cardiorespiratory capacity and lateral movement (p < 0.05). Moreover, males presented a higher percentage of asymmetry in upper limb strength. Female players showed better reaction time and greater flexibility (p < 0.05). Regarding the differences between categories, the under-16 players showed greater flexibility, gestural speed, vertical jump power, cardiorespiratory capacity and lateral movement compared to the under-14 players. These results can be used as reference values for coaches/physical trainers of younger categories to improve health control and physical performance planning.

RESUMO

Table tennis performance depends on multiple factors such as technique, tactics and fitness. Several studies have focused on investigating different technical-tactical variables. However, research analysing the specific physical qualities of this sport is scarce, particularly in the female sex. The aim of the present study was to assess the physical fitness variables associated with individual performance in elite table tennis players according to sex. Forty-eight elite players divided into males (n = 24; 25.38 ± 4.01 years) and females (n = 24; 22.33 ± 3.83 years) participated in the study. To determine physical fitness, participants performed vertical jump, hand grip strength, ergospirometry and lateral displacement tests (reaction time, displacement time and lateral acceleration). Male players showed higher values in vertical jump, hand grip strength and maximum oxygen consumption (p < 0.001). Likewise, male players moved laterally faster (p < 0.001). On the other hand, female players had a better reaction time towards the dominant side (p < 0.01). Elite male table tennis players showed better physical fitness compared to female players. Due to the scarcity of data on elite table tennis players, these results can serve as reference values for different table tennis practitioners.

RESUMO

A series of case studies aimed to assess bone and stress fractures in a 768-km ultra-trail race for 11 days. Four nonprofessional male athletes completed the event without diagnosing any stress fracture. Bone turnover markers (osteocalcin (OC), serum C-terminal cross-linking telopeptide of type I collagen (CTX), bone-specific alkaline phosphatase (BALP), and serum turnover calcium (Ca2+)) were assessed before (pre) and after the race (post) and on days two and nine during the recovery period (rec2 and rec9), respectively. Results showed: post-pre-OC = -45.78%, BALP = -61.74%, CTX = +37.28% and Ca2+ = -3.60%. At rec2 and rec9, the four parameters did not return to their pre-run levels: OC, -48.31%; BALP, -61.66%; CTX, +11.93% and Ca2+, -3.38%; and OC = -25.12%, BALP = -54.65%, CTX = +93.41% and Ca2+ = +3.15%), respectively. Our results indicated that the ultra-trail race induced several changes in bone turnover markers, uncoupling of bone metabolism, increased bone resorption: OC and BALP and suppressed bone formation: CTX and Ca2+. Bone turnover markers can help determine the response of bone to extreme effort and might also help predict the risk of stress fractures.

RESUMO

Background and objectives: Ultra-trail races can cause episodes of acute kidney injury (AKI) and exercise-associated hyponatremia (EAH) in healthy subjects without previous renal pathology. This systematic review aims to review the incidence of these two syndromes together and separately taking into account the length and elevation of the ultra-trail race examined. Materials and Methods: A systematic review was conducted through electronic search in four electronic databases (PubMed, EBSCO, Web of Science and Alcorze). Results: A total of 1127 articles published between January 2006 and December 31, 2021 were included, 28 of which met the inclusion criteria. The studies were categorized according to the length and stages of the race in four categories: medium (42 to 69 km), long (70 to 99 km), extra (>100 km) and multi-stage if they included various stages. A total of 2950 runners (666 females and 2284 males) were extracted from 28 publications. The AKI incidence found was 42.04% (468 cases of 1113), and 195 of 2065 were diagnosed with EAH, accounting for 9.11%. The concurrence of both pathologies together reached 11.84% (27 individuals) from a total of 228 runners with AKI and EAH simultaneously analyzed. Sorted by race category, the AKI+EAH cases were distributed as follows: 18 of 27 in the extra (13.63% and n = 132), 4 in the large (5.79% and n = 69) and 5 in the medium category (18.15% and n = 27). Conclusions: According to these results, extra and medium races showed a similar incidence of AKI+EAH. These findings underline the importance of the duration and intensity of the race and may make them responsible for the etiology of these medical conditions. Due to their variable incidence, EAH and AKI are often underdiagnosed, leading to poorer prognosis, increased condition seriousness and hindered treatment. The results of this review urge participants, coaches and race organizers to take measures to improve the early diagnosis and urgent treatment of possible EAH and AKI cases.

RESUMO

A series of case studies aimed to evaluate muscular fatigue in running a 768-km ultra-trail race in 11 days. Four non-professional athletes (four males) were enrolled. Muscle damage blood biomarkers (creatine kinase (CK), lactodeshydrogenase (LDH), aspartate transaminase (AST) and alanine aminotransferase (ALT) and lower limb strength were evaluated by using Bosco jumps test; squat jump (SJ), countermovement jump (CMJ) and Abalakov jump (ABA) were assessed before (pre), after the race (post) and for two and nine days during the recovery period (rec2 and rec9), respectively. Results showed: pre-post SJ = -28%, CMJ = -36% and ABA = -21%. Values returned to basal during rec9: SJ = -1%, CMJ = -2% or even exceeded pre-values ABA = +3%. On the contrary, muscle damage blood biomarkers values increased at post; CK = +888%, LDH = +172%, AST = +167% and ALT = +159% and the values returned gradually to baseline at rec9 except for AST = +226% and ALT = +103% which remained higher. Nonparametric bivariate Spearman's test showed strong correlations (Rs ≥ 0.8) between some jumps and muscle damage biomarkers at post (SJ-LDH Rs = 0.80, SJ-AST Rs = 0.8, ABA-LD H Rs = 0.80 and ABA-AST Rs = 0.80), at rec2 (SJ-CK Rs = 0.80 and SJ-ALT Rs = 0.80) and even during rec9 (ABA-CK). Similarly, some parameters such as accumulated elevation and training volume showed a strong correlation with LDH values after finishing the ultra-trail race. The alteration induced by completing an ultra-trail event in the muscle affects lower limb strength and may in some circumstances result in serious medical conditions including post- exertional rhabdomyolysis.

RESUMO

The study of the nutritional transition in Spain must combine sources concerning the health conditions and the nutritional profile of the population. Such an approximation to the issue is, as a rule, not possible until the two final decades of the 20th century. However, the report on the nutritional status of the Spanish army, undertaken by the American Interdepartmental Committee on Nutrition for National Defence (ICNND) in 1958, combines both approaches. The report is based on the medical examination of 10727 army drafts. First, the article contextualised the report's sample geographically and demographically; second, it validated the variables used statistically; and third, it explored the relationship between the diseases diagnosed, the biomarkers yielded by blood and urine tests, and the diet. The main results were as follows: (a) the report confirmed that the military population under examination did not suffer from severe dietary shortcomings; (b) the sample presents a double bias, geographical (overrepresentation of southern provinces) and institutional (underrepresentation of the land forces).

RESUMO

No research that has analyzed the structural characteristics, physiological profile, and energy demands in the game of table tennis as played by women is available. The present study aimed to evaluate the physiological, metabolic, and temporal variables of table tennis players and to observe gender differences. Forty-eight elite table tennis players participated in this study: 24 men (25.3 ± 4.07 years) and 24 women (22.3 ± 3.8 years). During simulated competition, temporal structure, heart rate (HR), and lactate (LA) were evaluated. The maximum ergospirometric evaluations were performed in a laboratory. The total table tennis (TT) time and the total resting time (TRT) were longer for men (p < 0.05), but game density was higher for women (p < 0.05). During rallies, the real playing time (RPT) was longer for women, while the TRT was longer for men (p < 0.05). The maximum HR, minimum HR, and maximum LA concentrations were higher for men (p < 0.05). The obtained data reveal gender differences in the physiological, metabolic, structural, and temporal variables in table tennis players. The analysis of the studied variables could allow training sessions to be planned and organized according to table tennis players' gender.

RESUMO

A case study involving a healthy trained male athlete who completed a 786 km multi-stage ultra-trail race. Several markers were analyzed in blood and urine samples: creatinine (SCR) for kidney damage, sodium ([Na+]) for hyponatremia, creatine kinase (CK) for exertional rhabdomyolysis, as well as other hematological values. Samples were taken before and after the race and during the recovery period (days 2 and 9 after the race). Results showed: SCR = 1.13 mg/dl, [Na+] =139 mmol/l and CK = 1.099 UI/l. Criteria for the determination of acute kidney damage were not met, and [Na+] concentration was above 135 mEq/L, indicating the absence of hyponatremia. Exertional rhabdomyolysis was suffered by the athlete (baseline CK increased fivefold), though this situation was reverted after 9 days of recovery. Ultra-trail races cause biochemical changes in athletes, which should be known about by healthcare professionals.

RESUMO

The aim of the present study was to analyze the effects of ballistic and power training on table tennis players' electromyography (EMG) changes. Thirty male table tennis players, who were able to perform top spin strikes properly, were randomly assigned to three groups: power training (PT; n = 10); ballistic training (BT; n = 10); and no training (CON = control group; n = 10). PT and BT were performed 3 times weekly for 8 weeks. Before and after training programs, a one-repetition maximum test (1RM) and the EMG activity of all the subjects' upper/lower body muscles while performing top spin strokes were analyzed. After training, significant interactions (group × time) were observed in increasing 1RM strength in upper/lower muscles (p < 0.05). However, neither training type had any significant effect on muscle EMG activity. These findings suggest that there should not necessarily be any significant change in the EMG signal after BT and PT despite the increase in muscle strength.

RESUMO

Padel is becoming one of the most widespread racket sports that may have potential health benefits. Considering that several myokines mediate the cross-talk between skeletal muscles and the brain, exerting positive effects on brain health status, this study was designed to evaluate the responses of brain-derived neurotrophic factor (BDNF), leukemia inhibitory factor (LIF), and irisin (IR) to padel competition in trained players and to determine whether these responses were sex-dependent. Twenty-four trained padel players (14 women and 10 men with a mean age of 27.8 ± 6.3 years) participated voluntarily in this study. Circulating levels of BDNF, LIF, and IR were assessed before and after simulated padel competition (real playing time, 27.8 ± 8.49 min; relative intensity, 75.2 ± 7.9% maximum heart rate). Except for BDNF responses observed in female players (increasing from 1531.12 ± 269.09 to 1768.56 ± 410.75 ng/mL), no significant changes in LIF and IR concentrations were reported after padel competition. In addition, no sex-related differences were found. Moreover, significant associations between IR and BDNF were established at both pre- and post-competition. Our results suggest that while competitive padel practice stimulates BDNF response in female players, padel competition failed to boost the release of LIF and IR. Future studies are needed to further explore the role of these exercise-induced myokines in the regulation of brain functions and to identify the field sports that can contribute to myokine-mediated muscle-brain crosstalk.

RESUMO

The aims of the present study were to examine the fitness characteristics of professional padel players and to determine differences in physical performance regarding players' gender. Thirty professional padel players (men: n = 15, age = 27.4 ± 6.8 years, height = 177.9 ± 4.0 cm; women: n = 15, age = 30.0 ± 4.2 years, height = 166.6 ± 4.8 cm) completed a 4-day evaluation process, including: isometric handgrip strength, sit and reach, 10 × 5 shuttle test, countermovement jump (CMJ), squat jump (SJ), Abalakov test, one-repetition maximum test (bench press, leg extension, leg curl, lat pulldowns, overhead press, and shoulder press), anthropometry and VO2 max tests. The men players had higher values in terms of weight, height, one maximum repetition, jump tests (CMJ and ABK) and VO2 max test than the women (p < 0.005). By contrast, the women had higher values for fat mass (p = 0.005; ES: 2.49). The values from this multifaceted test battery can be a useful guide for coaches regarding players' development in future evaluations and monitoring.

RESUMO

The status of trail running races has exponentially grown in recent years. The present study aimed to: (a) evaluate the acute response of ultratrail racing in terms of neuromuscular function, muscle damage and hydration status; (b) analyze if responses could differ according to training levels. Twenty runners participated in the present study. The participants were divided into amateur training level (n = 10; 43.30 ± 4.52 years) or high level competitors (n = 10; 41.40 ± 6.18). Neuromuscular response (squat jump, countermovement jump and Abalakov jump), muscle damage (alanine aminotransferase, bilirubin, creatine kinase and leukocytes) and hydration status (sodium and creatinine) were evaluated before and after the Guara Somontano Ultratrail Race (108 km distance, with an accumulated slope of 5800 m). The height and power achieved by vertical jumps were lower after the race (p < 0.001). The post-race muscle damage and creatinine parameters increased in both groups (p < 0.001). The high-level group obtained lower percentages of change in squat jump and countermovement jump than the amateur-level group (p < 0.05). However, the increase in creatinine was greater for the high-level group (p < 0.05). Ultratrail racing reduces neuromuscular function and increases muscle damage. High-level runners showed less neuromuscular fatigue compared to amateur ones.

RESUMO

Research on the acute physiological response to a padel match is limited. The present study aimed to: (a) evaluate neuromuscular, urinary, and hematological responses after simulated padel competition (SC) and (b) analyze possible gender differences. In this study, 28 high-level padel players participated (men = 13, age = 26.83 ± 6.57 years; women = 15, age = 30.07 ± 4.36 years). The following parameters were analyzed before and after SC: neuromuscular (hand grip strength, squat jump (SJ), countermovement jump (CMJ), and Abalakov jump (ABK)), hematological (red blood cells, hemoglobin, and hematocrit), and urinary (pH, specific gravity, microalbuminuria, and red blood cells). Significant gender differences were found in neuromuscular and hematological responses, with men obtaining higher values (p < 0.05). For the SC influence, changes were noted in ABK and microalbuminuria (p < 0.05). The percentages of change in hand grip strength, SJ (height and watts), CMJ (height), and ABK (height) were higher for men than women (p < 0.05). SC negatively influenced the neuromuscular parameters to a greater extent in women. Our results could be related to gender differences in game actions, the temporal structure, and anthropometric and physiological characteristics. Game dynamics and a different organic response between male and female padel playing were confirmed.

RESUMO

The aim of this study was to identify the differences in body composition and physical fitness between children who played table tennis regularly during a two-year period compared to physically active children who were not engaged in a regular activity. Three hundred seventy-four children aged 10 to 11 years were divided into two groups: table tennis players (n = 109 boys and 73 girls) and physically active group (n = 88 boys and 104 girls). Anthropometric analysis included body mass index, skinfolds, perimeters and bone diameters. Somatotype and body composition were determined according to age-specific equations. Physical fitness assessment included hand grip dynamometry (strength), sit-and-reach test (range of movement) and maximal multistage 20 m shuttle run test (cardiovascular fitness). The result show that children who regularly played table tennis had greater bone development and superior physical fitness compared to those who were physically active but not engaged in a regular physical activity. This is the largest study to date presenting data about the potential of table tennis to benefit health in children. These results constitute an important first step in clarifying the effectiveness of table tennis as a health-promotion strategy to encourage children to undertake regular physical activity and limit sedentary behavior.

RESUMO

PURPOSE: Descriptive psychopathology (DP, sometimes called psychopathology or phenomenology) is the language of psychiatry and is dedicated to the description of mental symptoms. Due to its importance, there is an ongoing case to put it back at the heart of psychiatry and its training. This study seeks to examine the literature on how to train psychiatry residents in DP, including reported educational interventions and educational methods. METHOD: The authors conducted a systematic review following the PRISMA and BEME guidelines to identify literature on how to train psychiatry residents in DP. In May 2019, they searched in Embase, ERIC, PsycINFO, PubMed, Scopus, and Web of Science; of 7,199 initial results, 26 sources were finally included for analysis. The assessment tools were the CRAAP test, Kirkpatrick's 4 levels, and (when applicable) the Medical Education Research Study Quality Instrument (MERSQI). RESULTS: The mean CRAAP score was 38.885 of a possible 50 (SD 0.983; range: 36.859-40.910). Fourteen sources (53.8%) had some kind of training evaluation: Kirkpatrick's level 1 was present in nearly all (13) and was the highest in half of them (7). Regarding the educational interventions, the mean MERSQI score was 10.592 of a possible 18 (SD 2.371; range 9.085-12.098). Lectures were the most widely reported educational method (5); among those in clinical settings, the live supervised interview with feedback was the most usual (4). CONCLUSIONS: Despite its core importance as the language of psychiatry, the literature about training psychiatry residents in DP is scarce and heterogeneous. General lack of training evaluation and ongoing overemphasis on Kirkpatrick's levels 1-2 at the expense of levels 3-4 are causes for concern. During the review process, the authors identified a selection of educational interventions that could serve as the basis for the design of new training efforts in both clinical and nonclinical settings. Topics for future research are also suggested, such as the role of DP in competency-based training frameworks now in vogue and a series of neglected contents. Finally, the combined use of the CRAAP test and the MERSQI may be useful for future systematic reviews in medical education.

RESUMO

The aim of this study was to analyze the distribution and effectiveness of the different types of smash in professional padel according to the area and direction of the strokes and the gender. Through systematic observation, 1.015 smashes from eight finals (four men's and four women's) of the professional matches were analyzed. The smashes were categorized into four types of smash: tray, flat, topspin and off the wall. The results showed both men's and women's that the tray is the most used smash by padel players, presenting a percentage of point continuity of almost 90%. The flat and topspin smashes are the strokes that achieve the highest percentage of winning points (near 60%), although this efficiency decreases significantly when the players move away from the net area (p < 0.05), especially in the flat smash. Men perform a higher percentage of winning smashes than women, mainly in the flat smash (p = 0.02). Furthermore, with regards to direction, flat and off the wall smashes are predominantly down the line strokes and women perform significantly more cross court topspin smashes than men (p = 0.005). The results shown could be used to design tasks and exercises by padel coaches at professional players.

RESUMO

Introduction: The deterioration of cognition is highly predominant in older adults. Objective: The aim of this study was to analyze the effects of a walking program on the cognition and blood concentration of lipids in women over 60 years of age who were being treated with lovastatin. Materials and methods: Participants were distributed in two groups: An exercise group (EG, n=45) with aerobic training and an inactive sedentary group (SG, n=22). The cognitive state of the subjects was assessed through the Spanish Mini-Cog Test version of the MMSE; lipoproteins were quantified using a lipid profile test, and the cardiorespiratory fitness was measured using the six-minute walking test (6MWT). Results: EG showed a significant increase (p<0.05) in cardiorespiratory fitness and in HDL-C concentrations. Furthermore, the results from the cognition tests showed a large effect size in spatial orientation and in and calculation. The decrease in LDL-C was not significant (p>0.05). Conclusion: A controlled and progressive walking program for older women treated with Lovastatin may induce a boost of brain activity linked to HDL-C, which could delay cognitive impairment.


Introducción. El deterioro cognitivo tiene una gran incidencia en el adulto mayor. Objetivo. El principal objetivo de este estudio fue analizar los efectos sobre la cognición y la concentración de lípidos de un programa de caminatas en mujeres mayores de 60 años tratadas con lovastatina. Materiales y métodos. Las participantes se distribuyeron en dos grupos: uno con ejercicio (EG, n=45) sometido a entrenamiento aeróbico y otro inactivo o sedentario (SG, n=22). El estado cognitivo se evaluó mediante la versión en español del Mini-Mental Test. Los niveles de lipoproteínas se midieron con una prueba de perfil lipídico y la aptitud cardiorrespiratoria se valoró con la prueba de caminata de 6 minutos (Six-Minute Walking Test, 6MWT). Resultados. El grupo con ejercicio mostró una mejora significativa (p<0,05) de la aptitud cardiorrespiratoria y de las concentraciones de colesterol HDL. Además, en la prueba de cognición se observó un efecto de gran tamaño en la orientación espacial, en la atención y en el cálculo. La reducción del colesterol LDL no fue significativa. Conclusión. Un programa de entrenamiento progresivo y supervisado para mujeres mayores tratadas con lovastatina, podría mejorar la actividad cerebral relacionada con el colesterol HDL, lo cual podría retrasar el deterioro cognitivo.
