MUSCLE DAMAGE DURING JUNIOR TENNIS TOURNAMENT: EFFECTS OF THE COMBINED RECOVERY METHOD Introduction Tennis movements comprise of acceleration, deceleration and changes in direction. These activities occur with high eccentric contractions of muscles, which are accompanied by symptoms such as muscle damage. The aim of this study was to investigate the muscle damage and the effects of the combined recovery method during junior single tennis tournament. Method Sixteen elite tennis players (experimental n=8, control n=8) participated in a 4-day tennis tournament. The experimental group participated in combined recovery method after every match. Blood samples were collected before, immediately after and 48h after the tournament to investigate creatine kinase (CK), lactate dehydrogenase (LDH) and C-reactive protein (CRP) levels. Delayed onset muscle soreness (DOMS) questionnaire was taken before, immediately after every match and 48h after the tournament. Result CK and LDH activity in the blood were increased significantly but there were no significant differences in CRP immediately after the tournament comparing to pre tournament. There were no differences on CK, LDH and CRP between the groups during and after the tournament. During tournament DOMS increased significantly in both groups. In the experimental group DOMS scores significantly decreased comparing to control group 48h after the tournament (p<0.05). Discussion Our results demonstrated that tennis matches increase significantly blood LDH, CK but not CRP levels. Previous studies have shown that eccentric contractions during sports games can increase CK and LDH enzymes in the blood, which show muscle damage indirectly (Kraemer et al., 2009; Nosaka et al., 2010; Potteiger, Blessing, & Wilson, 1992). Combined recovery method may not chanced the blood enzymes but decreased DOMS 48h after the last match Combined recovery can provide an advantage for being ready for the upcoming tournament.
