Tempo gasto em comportamento sedentário por praticantes de treinamento funcional de alta intensidade: um estudo com acelerometria

Abstract

With the technological advances and the behavioral changes it is noticed the population has been moving less and spending even more time in a sedentary behavior (SB). In the attempt to raise the levels of physical activity every day rise new training programs. Knowing the benefits of the time spent with moderate/vigorous physical activity each day programs of High Intensity Functional Training (HIFT) have been gaining more adepts. Objectifying verify the time spent in a sedentary behavior (SB) of HIFT practitioners, were analyzed 8 practitioners (29 ± 7 years old; 84±14 Kg; 174±10 cm, 27,7±2,3 kg/m2; time of practice 16±10,4 months). The volunteers used the wGT3X-BT, Actgraph® accelerometer during 7 days, including a weekend. It was verified that the sedentary behavior and light physical activity’s time did not show any big difference when compared the days with and without training, however the moderate/vigorous physical activities levels showed great differences: 619,4 ±124,3 minutes to the days without training and 585,0 ±275,7 minutes to days with training. But the MVPA’s level was higher in the days of training (39,8 ±10,4 minutes) in relation to the days without training (10,1±5,9 minutes). With this data, we assume the HIFT’s practitioners have a predisposition to spend more time in SB when they are not in a practice day, which lead us to believe the HIFT reduces the time spent in SB. However, besides the reduction of the time spent in SB, at least in the HIFT days of practice, the data are still alarming.
