Efeito agudo do treinamento funcional no equilíbrio dinâmico e estático em jovens adultos obesos

Abstract

One of the most important physical abilities, the postural control is the ability to keep static and dynamic balance. To keep balance may be a simple task for most people, but a series of information is required which allows the performance of adjustments that are needed for the balance control. Functional training has as its objective to develop the functional ability through specific exercises, aiming to promote and stimulate the proprioception, strength, muscle and cardiovascular strength, flexibility, motor coordination, laterality and balance. The objective of this study was to assess the acute effect of a functional training class on the dynamic and static balance of obese young adults. The population used for this study was young adults between the ages of 18 and 50 (33.81 ± 8.98), who exercise regularly for over six months and who has a frequency superior than three times per week, they were selected by convenience. The functional training contained eight stations, with two series of 15 repetitions and 1 min break. The assessed variables were the mean body fat percentage (33.24 ± 5.77), the BMI (29.96 ± 5.15), the initial dynamic balance (9.75 ± 1.75) seconds and the final dynamic balance (8.62 ± 1.47), while the initial static balance was (28 ± 1.64) seconds and the final static balance (28.87 ± 1.37). Paired Student’s t-test was used to assess the statistic difference between pre- and post-test, with a significance level of (p<0.05). Comparing the values obtained before the functional training, the dynamic balance reached a reduction of 1.13 seconds (p=0.000) and the static balance an increase of less than a second (p>0.126). The results of the present study suggest that Functional Training may improve balance in an acute way in obese youngsters, mainly in the case of dynamic balance.
