A aderĂŞncia Ă actividade fĂsica numa idade precoce influencia o envelhecimento activo?
Resumen:
IntroducciĂłn: Realizamos este estudio sustentado en torno al sinĂłnimo de salud que representa el deporte y la actividad fĂsica, que cobra aĂşn más relevancia en el sector de la poblaciĂłn de la edad adulta y vejez. Objetivos: con el objetivo de destacar el aspecto positivo que relaciona el ejercicio fĂsico con el envejecimiento activo de excelencia. MĂ©todos: para ello, llevamos a cabo un trabajo de revisiĂłn sistemática de investigaciones que hayan valorado los porcentajes de práctica de actividad fĂsica en dichas poblaciones. AsĂ tambiĂ©n, se comparan los datos con los de investigaciones que hayan evaluado la adquisiciĂłn y mantenimiento de hábitos de vida saludable en escolares, para ofrecer una perspectiva del mantenimiento en el futuro, es decir a lo largo de la vida. Resultados y discusiĂłn: una vez finalizado el estudio, las investigaciones cientĂficas confirman, segĂşn las cifras, extraĂdas y comparadas de los diferentes estudios; indican que mayormente los jĂłvenes, que tienen adquirido el hábito de actividad fĂsica, suelen mantener esos hábitos durante toda la vida y un porcentaje alto, continĂşan con un envejecimiento más saludable. Conclusiones: por lo tanto, se confirma que, el hábito de práctica de actividad fĂsica, adquirido en edades tempranas favorece un envejecimiento activo.Abstract:
Introduction: We carried out this study based on the synonym of health that represents sport and physical activity, which becomes even more relevant in the sector of the population of adulthood and old age. Aim: With the aim of highlighting the positive aspect that relates physical exercise with active aging of excellence. Methods: To do this, we carried out a systematic review of research that has assessed the percentages of practicing physical activity in these populations. Likewise, the data is compared with research that has evaluated the acquisition and maintenance of healthy lifestyle habits in schoolchildren, to offer a perspective of maintenance in the future, that is, throughout life. Results & discussion: Once the study is completed, the scientific investigations confirm, according to the figures, extracted and compared from the different studies; indicate that mostly young people, who have acquired the habit of physical activity, tend to maintain these habits throughout life and a high percentage, continue with healthier aging. Conclusions: Therefore, it is confirmed that the habit of practicing physical activity, acquired at an early age, favors active aging.Resumo:

Comparison of the two most commonlyused gold-standard velocity monitoringdevices (GymAware and T-Force) to assesslifting velocity during the free-weightbarbell back squat exercise
This study aimed to compare the reliability and agreement of mean velocity (MV) and maximal velocity (Vmax) between the two velocity monitoring devices (GymAware vs T-Force) most commonly used in the scientific literature. Twenty resistance-trained males completed two testing sessions. The free-weight barbell back squat one-repetition maximum (1RM) was determined in the first session (125.0 ± 24.2 kg; mean ± standard deviation). The second session consisted of two blocks of 16 repetitions (six repetitions at 45% 1RM and 65% 1RM, and four repetitions at 85% 1RM). Half of the repetitions were performed with the GymAware on the left side of the barbell and the other half of the repetitions were performed on the right side of the barbell (opposite placement for the T-Force). MV and Vmax were recorded simultaneously with the GymAware and T-Force. The overall reliability, which was calculated pooling together the data of three loads, did not differ between the T-Force (coefficient of variation (CV) = 5.28 ± 1.79%) and GymAware (CV = 5.79 ± 2.26%) (CVratio = 1.10), but the reliability was higher for Vmax (CV = 5.08 ± 1.79%) compared to MV (CV = 5.98 ± 2.73%) (CVratio = 1.18). MV was significantly higher for the T-Force (p < 0.001, Δ = 4.42%), but no significant differences were detected between the devices for Vmax (p = 0.455, Δ = 0.22%). These results support the use of both the GymAware and T-Force as gold-standards in studies designed to validate other velocity monitoring devices. However, systematic bias, albeit rather constant, exists for the magnitude of MV between the two devices
