其他摘要：Body Attack is a cardiovascular training program inspired in many sports to improve cardiovascular and strength conditioning. These routines of high-intensity interval training combine athletic aerobic skills with strength and balance exercises. It is not known if this form of routine is as effective as other traditional modes (aerobic high and low impact, step, cycling and running). The purpose of this study was to investigate the heart rate and perceived exertion responses during a Body Attack routine. The sample for this study comprised ten voluntary young females Physical Education and School Sports students (Age mean=21.5±1.6; Height mean=1.65±0.06; Weight mean=60.3±5.19; BMI=22.1±1.89). The routine comprised a warm up track; seven cardiovascular tracks, three strength tracks and flexibility and relaxation track. The heart rate was measured during the routine using Polar Team System and perceived exertion using Borg¿s 6-20 scale, immediately after each track. Repeated measures analysis of variance test was used to compare tracks. The heart rate mean of all routine was 148±16bpm and differences were obtained within performed tracks (F=701.7 p=0.000). These results were within the cardiovascular target training zone mean from all tested subjects (133±1.2 to 174±1.3). The subjects were near the cardiovascular superior limit (166±16.7bpm) in track 4 and inferior limit in track 3 (135±21bpm). Perceived exertion mean values were 14±2, between the 12-15 suggestions to elicit a training effect. The perceived exertion assessment was higher than other studied modes. Body-attack activity has potential to improve aerobic fitness of its participants.
