Acute effects of proprioception, massage and dynamic stretching warm up protocols on serum CK and LDH activity levels after one session of Plyometric training in male volleyball players

The purpose of the present study was to identify the acute effect of proprioception, massage and dynamic stretching warm up protocols on serum CK and LDH activity levels after one session of Plyometric training in men volleyball players. Thirty-two volleyball players (mean age: 21/20 ± 1/73 years and body mass index: 22/11 ± 2/53 kg / m²) were randomly assigned to 4 groups of proprioception, massage, dynamic stretching and control groups. Experimental groups (after 15 minutes of specified warming-up) and control group performed 30 minutes plyometric training. Blood samples were taken before, immediately after and then 24 and 48 h after exercise. Immediately after plyometric training, the serum level of CK activity in massage, dynamic stretching and control groups were significantly increased (P<0.05). After 48 hours, the serum level of CK activity reached to the basal level, excluding the massage group which was significantly higher than basal level (P=0.0001). No significant change was found in the level of LDH activity in any group (P>0.05). It seems that in volleyball the use of proprioceptive warm up training is more effective for prevention of muscle injuries in comparison to other warming-up methods
