High-intensity exercise is gaining popularity in the public sector; empirical research on the efficacy of these types of activities is emerging.
PURPOSE: To determine the efficacy of a novel, 16-wk training program on measures of aerobic fitness, agility, aerobic power, muscular endurance, lower body explosive power, & self-reported activity level.
METHODS: The intervention group (N=129; 63 f, 24.65±5.55 yrs) had a baseline VO2max of 39.83±9.13. These individuals participated in 26, 70-min exercise sessions, & 4 fitness testing sessions over the course of 16 wks. Participants were matched with a non-exercise control group, paired by sex, age, & baseline VO2max. The control group (N = 129, 63 f, 24.26±5.59 yrs) had a baseline VO2max of 39.86±8.59 & completed pre & post VO2max testing only.
RESULTS: Participants in the fitness intervention group significantly increased their VO2max (2.72±0.31, Mdiff±SE; p<.001) & reported being more physically active (0.42±0.11, Mdiff±SE; p<.001) after the 16-wk intervention. Participants in the control group showed no significant pre-post changes. Participants in the fitness intervention showed a significant improvement in 3 of 5 components of the fitness field tests. Specifically, significant improvements were observed for the 1-min rower test (5.32±0.505, Mdiff±SE; p<.001), the 1-min push-up test (8.168±.709, Mdiff±SE; p<.001), & the 1.5-mile run test (1.79±0.169, Mdiff±SE; p<.001). No significant improvements were observed for the shuttle run (p=.173) or standing long jump (p=.137).
CONCLUSIONS: These findings demonstrate the efficacy of a novel, HICRT intervention across multiple dimensions of fitness for young & middle aged adults.
