Effects of high-intensity interval training on pulmonary function.

摘要: To determine whether high-intensity interval training (HIT) would increase respiratory muscle strength and expiratory flow rates more than endurance (ET), 15 physically active, healthy subjects (untrained) were randomly assigned to an ET group (n = 7) or a HIT 8). All performed incremental test exhaustion (VO2max) on cycle ergometer before after training. Standard pulmonary function tests, maximum inspiratory pressure (PImax), (PEmax), maximal volume loops pre each week of 4-week program, 3 days week, at 90% their VO2max final workload, while the exercise 60-70% VO2max. The five 1-min bouts with 3-min recovery periods cycled for 45 min continuously. A five-mile time trial (TT) was prior to, 2 weeks, completion Both groups showed improvements (P 0.05) between groups. increased in either group. These data suggest that both whole-body are effective increasing offering time-efficient alternative improving aerobic capacity performance.
