The Acute Physiological and Perceptual Responses Between Bodyweight and Treadmill Running High-Intensity Interval Exercises.

OBJECTIVE

The purpose of this study was to compare the acute physiological, perceptual, and enjoyment responses between bodyweight high-intensity interval exercise (BW-HIIE) and treadmill running high-intensity interval exercise HIIE (RUN-HIIE).

METHODS

Twelve adults [age: 29.5 ± 5.3 years; weight: 70.9 ± 15.0 kg; height: 167.9 ± 8.9 cm; peak oxygen consumption (VO peak): 48.7 ± 6.5 ml min·kg] performed both RUN-HIIE and BW-HIIE. RUN-HIIE consisted of two sets of 5, 60-s (s) run intervals at 100% of the speed achieved during VO peak testing followed by 60s of walking at 4.02 km/h. BW-HIIE consisted of two sets of 5, 60s 'all-out' effort calisthenic exercises followed by 60s of marching in place at 100 steps per minute. Oxygen consumption (VO), blood lactate (B), heart rate (HR), and rating of perceived exertion (RPE) were measured during exercise. Physical activity enjoyment (PACES) was assessed post-exercise. Creatine Kinase (CK) was measured before exercise and 48-h post-exercise. Muscle soreness was assessed before exercise, post-exercise, and 48-h post-exercise.

RESULTS

Oxygen consumption relative to VO peak was higher ( < 0.001) during RUN-HIIE (88 ± 3%) compared to BW-HIIE (77 ± 4%). HR relative to HRpeak was higher ( = 0.002) for RUN-HIIE (93 ± 1%) compared to BW-HIIE (88 ± 2%). B was higher ( < 0.001) after BW-HIIE (11.2 ± 3.2 mmol/l) compared to RUN-HIIE (6.9 ± 2.0 mmol/l). Average RPE achieved was higher ( = 0.003) during BW-HIIE (16 ± 2) than RUN-HIIE (14 ± 2). PACES was similar for RUN-HIIE and BW-HIIE ( > 0.05). No differences ( > 0.05) in CK were observed between RUN-HIIE and BW-HIIE.

CONCLUSION

Our results indicate 'all-out' calisthenic exercise can elicit vigorous cardiorespiratory, B, and RPE responses. Implementing this style of exercise into training requires minimal space, no equipment, and may elicit cardiometabolic adaptations seen with traditional forms of high-intensity exercise.
