Different recovery types do not affect training parameters in high-intensity interval training based on whole body exercise

The purpose of the study was to evaluate the effects of two recovery types on the training parameters in high intensity interval training (HIIT) sessions using body weight training, the recovery included active and passive. Participating in this study, twenty male voluntaries performed two acute single sessions with a break between sessions of 7 days, each training session, was composed by (20-min duration sessions of a HIIT whole body training, consisting of 20 sets of 30 seconds at stimulus all-out of intensities of high-intensity interval training using different types of recovery, the time of duration by recovery was 30 seconds. Each cycle of exercise consisted of 30 seconds of "maximum intensity" stimulation followed by 30 seconds of recovery (active or passive). The following parameters were evaluated: heart rate, perceived exertion, perceived recovery, lactate concentration, feeling scale and number of movements in total. In the present study no differences were found in relative heart rates, perceived exertion, and lactate concentrations between protocols. No differences (p>0.05) were found on number total movements (Active: 695±52, Passive: 723±56) between protocols. Additionally, significant reductions (p<0.0001) on feeling scale were found after the exercise session using Active (Before: 4.35±0.58, After:0.85±1.22) and Passive (Before:4.30±0.80, After:1.00±1.45) recovery type, no differences were found between protocols. There were no differences (p<0.05) found for the respective area under the curve for rate of perceived recovery between protocols (Active:59.70±18.69, Passive: 64.58±14.89).
