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.

Magnani Branco, BH, Carvalho, IZ, Garcia de Oliveira, H, Fanhani, AP, Machado dos Santos, MC, Pestillo de Oliveira, L, Macente, SB, and Nelson, NJ. Effects of 2 types of resistance training models on obese adolescents' body composition, cardiometabolic risk, and physical fitness. J Strength Cond Res 34(9): 2672–2682, 2020—The main objective of this study was to investigate the effects of 2 types of resistance training (RT) models in conjunction with interdisciplinary interventions by other health professionals to reduce the body fat and cardiometabolic risk of obese adolescents while improving their general health-related physical fitness. The 12-week analyses involved 18 male adolescents who were split into 2 groups (weight lifting: n = 9 and functional: n = 9), with equalization according to the primary muscle group (whenever possible), the effort:pause ratio, and intensity. The results showed reductions in fat mass and body fat, as well as in waist and hip circumferences (p < 0.05) after the intervention period. However, no significant differences were observed in terms of the body mass, body mass index, neck circumference, systolic and diastolic blood pressures, and for lean mass (p > 0.05) after the respective period. Maximal isometric strength, abdominal strength resistance, flexibility, and maximal oxygen consumption all produced significant increases after the interventions (p < 0.05). There were reductions in low-density lipoproteins and triglyceride levels after the intervention period (p < 0.05). For fasting glycemia, high-density lipoproteins, and alanine aminotransferase, no differences were observed (p > 0.05). In addition, no differences were observed in rating of perceived recovery, internal training load, or caloric intake (p > 0.05). With the results presented, it is concluded that both RT methods were effective at reducing both fat mass and body fat, thus improving health-related physical fitness components and decreasing cardiometabolic risk.

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 &lt; 0.05). There was a group time interaction with body fat percentage being lower post-intervention in the SPG (p &lt; 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.Clinical Trial Registration:https://ensaiosclinicos.gov.br/, identifier: RBR-45ywtg.

Evidências demonstram o aumento da expectativa de vida em pessoas acima dos 60 anos. O lazer, aliado a outros determinantes, pode ser decisivo para a qualidade de vida da pessoa idosa. Este estudo analisou o direcionamento das atividades de lazer desenvolvidas nos Centros de Convivência de Idosos (CCI) nos Municípios da Região Norte do Paraná e a importância do gosto do idoso na seleção das atividades dos Centros de Convivência. Essa é uma pesquisa descritiva, de caráter quantitativo realizada com uma amostra composta por 200 idosos de 10 Municípios, os quais responderam a um questionário composto por questões abertas, fechadas e mistas respaldadas pelos objetivos propostos. Os dados foram analisados por meio de estatística descritiva, frequência e porcentagem. As atividades desenvolvidas pelos centros de convivência analisados não estão em consonância com o gosto dos indivíduos e se repetem no decorrer do tempo, não respeitando as mudanças culturais e sociais de cada geração. Conclui-se que, atender ao gosto dos idosos emergiu como um fator indispensável para a emancipação, o desenvolvimento psíquico e físico visando a amplitude de possibilidades para o envelhecimento saudável e consequentemente, para a qualidade de vida.

Esta pesquisa buscou investigar a valorização do autoconceito em equipes de voleibol de alto rendimento. Foram sujeitos 31 atletas de voleibol, das categorias adulto masculina, juvenil masculina e juvenil feminina. Utilizou-se como instrumento de medida a Escala Fatorial de Autoconceito. Para a análise dos dados foram utilizados os testes kruskall-Wallis e MANOVA. Os dados demonstraram que as equipes comportaram-se de forma semelhante quanto aos fatores do autoconceito, ocorrendo diferença estatisticamente significativa para o fator segurança entre as equipes juvenis feminina e masculina. O fator ético-moral apresentou altos níveis de valorização em relação aos outros fatores, sendo estatisticamente superior nas equipes feminina e masculina juvenis. Na equipe masculina adulta este fator foi superior aos fatores "somático", "receptividade" e "atitude social". O sentimento de pertencer a um grupo socialmente valorizado parece ser o principal motivo de os atletas se perceberem como sujeitos morais. Conclui-se que existem diferenças de gênero quanto ao autoconceito ("segurança"), de modo que o esporte favorece o sentimento de "moralidade" e vivências de autoconsideração, propiciando a congruência do self-experiência.
