Improving aerobic capacity through active videogames: A randomized controlled trial

La tasa de mejoria mayor volumen de trabajo entre los diferentes tipos de Juegos de Video Activos (VJA) en jovenes adultos sedentarios fue investigado. Mejoras de la capacidad aerobica despues de una intervencion de 6 semanas entre los tipos de AVG tambien se comparo. Veinte participantes, despues de evaluaciones de referencia, fueron aleatorizados en uno de tres grupos paralelos: VJA estructurado (n= 6), VJA no estructurada (n = 7) y un grupo control (n = 7). Los participantes jugaron sus respectivos VJA 3 veces por semana durante 6 semanas (30 minutos-sesion). El grupo control mantuvo sus actividades normales. Trabajo maximo fue mejorado pelo dos VJA despues de cuatro semanas, pero solo el structurado mantuvieron esta mejora en la semana cinco y seis. La capacidad aerobica fue mejorado por tanto la no estructurada (Pre: 36,0 ± 5,2ml.kg.min-¹, Post: 39,7 ± 4,9 ml.kg.min-¹, p = 0,038) y estructurada (Pre: 39,0 ± 5,9ml.kg.min-¹, Post: 47,8 ± 4,3ml.kg.min-¹, p = 0,006). VJA. Estructurado VJA ofrecer mayores beneficios para la salud en la capacidad aerobica y la carga de trabajo maximo en jovenes varones sedentarios pero por lo demas saludables relativas a VJA no estructurada.

Acute intensity and motivation to play: comparison of structured and unstructured active video games - a pilot study

Sedentary lifestyle is a serious health problem in the world and, in the Brazil, 80% of the population presents this behavior with a lower level of physical activity [1]. This behavior is associated with serious health risks and inversely related to physical activity (PA). Low levels of physical activity may develop or aggravate chronic degenerative diseases; however, this PA promotion prevents and treats diseases such as hypertension, obesity, and diabetes. Therefore, PA is important and is conceptualized as any bodily movement with sufficient intensity to elevate the energy expenditure above resting levels [2].

High-Intensity Interval Training in Heart Transplant Recipients: A Systematic Review with Meta-Analysis

Heart transplantation (HTx) is considered an efficient and gold-standard procedure for patients with end-stage heart failure. After surgery, patients have lower aerobic power (VO2max) and compensatory hemodynamic responses. The aim of the present study was to assess through a systematic review with meta-analysis whether high-intensity interval training (HIIT) can provide benefits for those parameters. This is a systematic review with meta-analysis, which searched the databases and data portals PubMed, Web of Science, Scopus, Science Direct and Wiley until December 2016 (pairs). The following terms and descriptors were used: “heart recipient” OR “heart transplant recipient” OR ”heart transplant” OR “cardiac transplant” OR “heart graft”. Descriptors via DeCS and Mesh were: “heart transplantation’’ OR “cardiac transplantation”. The words used in combination (AND) were: “exercise training” OR “interval training” OR “high intensity interval training” OR “high intensity training” OR “anaerobic training” OR “intermittent training” OR “sprint training”. The initial search identified 1064 studies. Then, only those studies assessing the influence of HIIT on the post-HTx period were added, resulting in three studies analyzed. The significance level adopted was 0.05. Heart transplant recipients showed significant improvement in VO2peak, heart rate and peak blood pressure in 8 to 12 weeks of intervention.

PERFIL DO DESEMPENHO MOTOR DE CRIANÇAS COM DEFICIÊNCIA INTELECTUAL

Objective: To analyze the motor performance of children with intellectual disabilities through the monopedal jump test of the KTK battery (Korperkoordination test fur Kinder). Materials and Methods: This was a descriptive, pre-experimental study analyzing eight intellectual disabled children of each gender aged 6 to 13 years. The subjects were tested for their strength and motor coordination of lower limbs during the monopedal jump test of the KTK battery. Asymmetry in motor performance between the hemibody was analyzed through the t test for dependent samples. Results: Six volunteers were excluded for failing to perform the test correctly. Eight male children (9.88 ± 1.89 years) showed better results on their left leg. However, no statistically significant differences were observed when comparing the right and left leg (p = 0.211). In general, the participants were classified as having insufficient coordinative motor performance (≤ 56) in both legs. Conclusion: Children with intellectual disabilities showed a profile of motor coordination below the recommended for their age, although some participants showed better results. Thus, it is necessary to conduct longitudinal interventional studies with greater sample sizes and different tests in order to assess this phenomenon.
