Abstract

INTRODUCTION
The purpose of this study was to measure changes of rest interval following eccentric muscle contraction exercise on circulating substance, parameters related to damage and regeneration in skeletal muscle.
METHOD
Fifteen healthy men who had not been involved in a resistance-training program at least 6 months prior to the present study were recruited as subjects. All subjects performed maximal eccentric exercise of the elbow flexors with their dominant arm. The exercise consisted of 10 sets of 6 maximal voluntary eccentric contractions of the elbow flexors with 1-min, 3-min and 5-min rest between sets. Circulating substance (leukocytes, neutrophils), Muscle damage index (ROM, VAS, Plasma CK) and muscle regeneration (CD34+) were examined before, immediately after, 1, 2, 3, and 4 days following the exercise.
RESULT
VAS and Plasma CK were significantly decreased in the 3-min and 5-min rest than in the 1-min (p<.05). ROM was significantly faster in the 3-min and 5-min rest than in the 1-min (p<.05). Circulating substance (leukocytes, neutrophils and CD34+ were not significantly different at time course between rest.
CONCLUSION
These results confirmed that difference in rest time affects a muscle damage related index.
