Adaptações fisiológicas crônicas de um programa de ginástica coletiva coreografada com uso de Kangoo Jumps em mulheres jovens

Abstract

The aim of this study was to investigate the chronic effects of a choreographed collective gymnastics program using Kangoo Jumps (KJ) on cardiorespiratory and muscle parameters of young women. Thirty-four young women were randomized into an exercise group (EG; n = 17; 29.76 ± 4.20 years) or a control group (CG; n = 17; 26.17 ± 4.95 years). The EG held 16 classes of collective gymnastics choreographed with KJ, lasting 30 minutes each, twice a week with the songs in the cadences of 128, 132 and 136 beats per minute (b.min-1) in each mesocycle. The CG performed health care activities in eight 30-minute sessions, held once a week. Pre- and post-training measures of cardiorespiratory and muscle outcomes were performed. Data analysis was performed using the Generalized Estimating Equations test and Bonferroni's post-hoc test (α = 0.05). The results of the present study showed that the eightweek training of choreographed gymnastics with the use of KJ promoted positive changes in comparison to the control group in the exhaustion time, index of submaximal perceived exertion in fixed stage in the maximum incremental test and height of the squat jump jump. In addition, both interventions (GC and EG) resulted in positive changes in the perceived exertion index in a movement economy test with the use of KJ, submaximal heart rate in a fixed stage in the maximum incremental test and in the rate of12 force application in protocol with the use of KJ, modifications that cannot be attributed exclusively to the choreographed gymnastics program with the use of KJ. Finally, the other cardiorespiratory and muscle outcomes were maintained throughout the intervention, it is important to note that the intensity perceived by the participants (IEP) decreased over the mesocycles, even with the increase in the musical rhythm imposed on the choreographed gymnastic group with the use of KJ, which can contribute to explain the present results. We concluded that an eight-week choreographed collective gymnastic intervention using KJ in young women was effective in modifying cardiorespiratory and skeletal muscle parameters, but insufficient to promote improvements in the variables related to oxygen consumption.
