PURPOSE: The purpose of this study was to examine the effects of whole body periodic acceleration (pGz) on exercise induced muscle damage (EIMD) related symptoms induced by unaccustomed eccentric arm exercise.
METHODS: Seventeen active young men (23.4 ± 4.6 yrs) made six visits to the research facility over a two-week period. On day one, subjects performed a maximum 1-repetition (1RM) elbow flexion test and were randomly assigned to the pGz (n=8) or control group (n=9). Criterion measurements were taken on Day 2, prior to and immediately following performance of the eccentric exercise protocol (10 sets, 10 repetitions using 120% 1RM) and after the recovery period. During subsequent sessions (24, 48, 72, and 96 h) these data were collected before pGz or passive recovery. Measurements included: isometric strength (MVC), blood markers (CK, MYO, IL-6, TNF-α, TBARS, PGF2α, protein carbonyls, uric acid, and nitrites), soreness, pain, circumference, and range of motion (ROM).
RESULTS: Significantly higher MVC values were seen for pGz throughout the recovery period. Within group differences were seen in MYO, IL-6, IL-10, protein carbonyls, soreness, pain, circumference, and ROM showing small negative responses and rapid recovery for the pGz condition.
CONCLUSION: Our results demonstrate that pGz can be an effective tool for the reduction of EIMD and may contribute to the training-adaptation cycle by speeding-up the recovery of the body due to its performance loss lessening effect.
