Effects of Mid-Season Camp Period Loading on Sports Injury Anxiety and Physical Performance of Professional Male Soccer Players

Objective This study aimed to investigate the effects of 3-week mid-season camp period loading on sports injury anxiety level and physical performances of professional male soccer players. Methods Thirty-four male soccer players [mean age 21.76 (3.42) y] were included in the study. Sports injury anxiety level with the Sports Injury Anxiety Scale, quadriceps muscle strength was assessed with the digital hand dynamometer, flexibility was assessed with the sit-and-reach test, dynamic balance was assessed with the Y balance test, power was assessed with the single-leg jump test, agility was assessed with the t-test, and sprint was assessed with the 20-m sprint test. Results There was no significant difference between the pretest and posttest values of Sport Injury Anxiety Scale scores (p=0.657). A significant difference was found between the pretest and posttest values of quadriceps muscle strength and dynamic balance (p=0.040, p=0.048, respectively). There was no significant difference between the pretest and posttest values of flexibility, single-leg jump, agility, and sprint (p=0.289, p=0.128, p=0.064, p=0.471, respectively). Conclusion The 3-week mid-season camp period loading improved quadriceps muscle strength and dynamic balance, but did not affect the sports injury anxiety level, flexibility, jumping performance, agility, and sprint. The results should be considered by sports professionals. It is recommended that further studies be conducted on the effects of different camp period contents, durations and loads in regions with different physical conditions (sea level, high altitude, etc.).
