Background Older people often do not meet the recommended levels of exercise required to reduce functional decline. Social interaction is mentioned by this cohort as a reason for joining group-based exercises, which does not occur when exercising alone. This perspective shows that exergames can be used as motivational resources. However, most available exergames are generic, obtained from commercial sources, and usually not specifically designed or adapted for older people. Objective In this study, we aim to co-design and develop a new exergame alongside older participants to (1) tailor the game mechanics and optimize participants’ adherence to and enjoyment of exercise; (2) test the participants’ functional capacity, motivation, and adherence to the exergaming program; and (3) compare these scores between those who played alone and those who played with peers. Methods We conducted a co-design process to develop a new exergame adapted to older people. For user testing, 23 participants were divided into 2 groups to play individually (alone group) or to compete in pairs (with peers group). They played the game twice a week, resulting in 21 exergaming sessions. We assessed the participants’ General Physical Fitness Index (GPFI) before and after the user testing. We also administered questionnaires about the gaming experience and exercise adherence with its motivators and barriers. Results We introduced a new bowling exergame for Xbox with a Kinect motion sensor that can be played in single or multiplayer mode. For the GPFI measurements, the sample was homogeneous in the pretest (with peers group: mean 40.5 [SD 9.6], alone group: mean 33.9 [SD 7.8]; P=.11). After the exergame testing sessions, both groups had significant gains (with peers group: mean 57.5 [SD 8.7], P=.005; alone group: mean 44.7 [SD 10.6]; P=.02). Comparing the posttest between groups, it was found that the group in which participants played with peers had better outcomes than the group in which participants played alone (P=.02). Regarding the gaming experience and exercise adherence, both groups recognized the benefits and expressed enthusiasm toward the exergame. Conclusions The findings suggest that the developed exergame helps in improving the functional capacity and adherence to physical exercise among older people, with even better results for those who played with peers. In addition to leading to more appropriate products, a co-design approach may positively influence the motivation and adherence of participants.

Postoperative ScvO(2) can be a valuable tool to predict OD after major cardiac surgeries. Its kinetics should be carefully followed in that setting.

Resumo: O objetivo deste estudo é apresentar possibilidades para o ensino dos elementos técnico-táticos defensivos individuais do handebol nas categorias infantil, cadete e juvenil. Para isso, são discutidas as características inerentes ao desenvolvimento dos jogadores em cada etapa, assim como os aspectos que permeiam alguns dos elementos técnico-táticos defensivos individuais (como a marcação, a flutuação, a cobertura e a dissuasão) e os sistemas defensivos. Desta forma, foi possível verificar que o método situacional é importante para contemplar diferentes aspectos em cada categoria, por fornecer subsídios motores e cognitivos para o norteamento das tomadas de decisão dos defensores. Abstract:The aim of this work is to present possibilities for teaching handball's individual technical-tactical defensive elements in under-14, under-16 and under-18 categories. For this, we discuss characteristics inherent in players' development at each age group, as well as aspects pervading some individual technical-tactical defensive elements (such as marking, floating, coverage and dissuasion) and defensive systems. Thus, it was possible to see that the situational method is important for considering different aspects in each category since it provides motor and cognitive experiences for defenders' decision-making.Resumen: El objetivo de este estudio es presentar las posibilidades para la enseñanza de los elementos técnico-tácticos defensivos individuales de balonmano en las categorías infantil, cadete y juvenil.

Así, fue posible verificar que el método situacional es importante para contemplar diferentes aspectos en cada categoría al subsidiar los dominios motores y cognitivos de la toma de decisión de los defensores.

RESUMOIntrodução: O envelhecimento traz várias modificações, entre as quais o declínio progressivo das funções fisiológicas do organismo. Tanto o treino de força quanto um programa de resistência aeróbica são importantes para evitar o declínio funcional associado à idade. Objetivo: Avaliar os efeitos de um programa de treinamento combinado de força e resistência aeróbica sobre a força de preensão manual, a massa muscular, a resistência e potência aeróbica de idosas. Métodos: Trinta e cinco mulheres (65,7 ± 6,68 anos) foram divididas em três grupos: treinamento combinado (TC; n = 15), treinamento de força (TF; n = 10) e treinamento aeróbico (TA; n = 10). Cada grupo treinou duas vezes por semana durante oito semanas, sendo que o grupo TC teve treinamento de força e aeróbico uma vez por semana. Foi utilizado o teste estatístico ANOVA e t de Student, com p ≤ 0,05. Resultados: Foi possível verificar melhoras significativas (p ≤ 0,05) dos valores de VO 2pico no momento da determinação do limiar anaeróbico e aumento na força de preensão manual em todos os grupos pesquisados, assim como dos valores de massa muscular do vasto lateral (p ≤ 0,05). Conclusão: Os resultados sugerem que um programa de treinamento combinado é tão eficaz para ocasionar aumentos de massa muscular, potência e resistência aeróbica de idosas, quanto o treinamento de resistência aeróbica ou força realizado duas vezes por semana, organizados separadamente.Descritores: saúde do idoso; força muscular; treinamento de resistência; exercício. ABSTRACT Introduction: Aging brings several modifications, including the progressive decline of physiological functions of the body. Both strength training and an aerobic endurance program are important to avoid functional decline

Long duration exercise may lead to the occurrence of urine abnormalities. Aiming to investigate the effects of triathlon training and competition on the renal function, twelve male triathletes (32.60 ± 5.10 years, 175.04 ± 6.67m, 71.83 ± 7.42Kg) were studied during the 12-week training protocol and after a Half Ironman. Urine was collected in M-1 -beginning of the training season, M-2 -before the competition and M-3 -after the half ironman. Urine pH was measured using reagent strips, density with a refractometer, proteinuria by Bradford assay, creatinine with a colorimetric assay and blood cells by microscopy. Data were analyzed using Shapiro-Wilk test, One-Way ANOVA and Tukey-Kramer test (p < 0,05). Changes were found after the competition in the protein (M-1= 7.41 ± 2.48; M-2= 7.57 ± 3.74; M-3= 86.10 ± 76.21 mg/mL), creatinine (M-1= 157.66 ± 41.59; M-2= 177.68 ± 44.46; M-3= 316.46 ± 132.86 mg/mL), erythrocytes (M-1= 1060.00 ± 0.30; M-2= 1142.86 ± 377.96; M-3= 52555.56 ± 58.65 units/mL) and leucocytes (M-1= 2375.00 ± 744.02; M-2= 2090.00 ± 0.50; M-3= 5000.00 ± 2738.60 units/mL) excretion when compared to the other collection times. These effects are probably due to the exercise-induced modifications in the glomerular membrane and endocrine variables such as anti diuretic hormone, catecholamines and aldosterone.
