Özet
The purpose of this study was to investigate the impact of exercise induced muscle damage created by upper arm on target shooting performance. Eleven healthy and moderately active males [(mean +/- SD) age: 21.91 +/- 2.66 years; stature: 175.33 +/- 4.83cm; body mass: 70.12 +/- 6.83kg; body fat %: 11.20 +/- 3.83], who did not perform any high intensity physical training towards upper body extremities during last 3 months, volunteered to participate in this study. Target shooting performance for both arms were measured, following assessment of serum CK activity and muscle soreness level using visual analogue scale, before (baseline) and at 5th minute, 24th, 48th, 72nd, 96th and 120th hours after muscle damaging exercise protocol. Two sets of 25 repetitions, totally 50 maximal eccentric contractions were performed with forearm flexors, as muscle damage exercise protocol. Repeated measure ANOVA and Friedman test was used for statistical analysis. Repeated measures ANOVA showed significant changes in serum CK activity [F(5-50)=40.028, p<0.01] and in target shooting performance for both dominant [F(6-60)=3.271, p<0.01] and non-dominant [F(6-60)=3.136, p<0.01] arms, relevant with time intervals. According to Friedman test, muscle soreness for both arms changed significantly (p<0.01) within time intervals. Compared to baseline values significant (p<0.05) changes were recorded following muscle damaging exercise protocol regarding to serum CK activity, muscle soreness and shooting performance. Consequently, the results of this study revealed that exercise induced muscle damage affect target shooting performance negatively. The respondents should be careful while adding unaccustomed exercises including intense eccentric contractions during the process of training planning, in sports which target shooting skills are important features.
