Objective. e objective of this study is to find and compare the effects of isokinetic training and virtual reality training on sports performances in university football players with chronic low back pain. Design. is is a randomized, double-blinded controlled study. Methods. e study was conducted on 45LBP participants at university hospital. First group (n � 15) received isokinetic training, second group (n � 15) received virtual reality training, and the control group (n � 15) received conventional training exercises for four weeks. Clinical (pain intensity and player wellness) and sports performance (40 m sprint, 4 × 5 m sprint, submaximal shuttle running, countermovement jump, and squat jump) scores were measured at baseline, after 4 weeks, 8 weeks, and 6 months. Results. Four weeks following training VRT group shows more significant changes in pain intensity and player wellness scores than IKT and control groups (p ≤ 0.001). Sports performance variables (such as 40 m sprint, 4 × 5 m sprint, submaximal shuttle running, countermovement jump, and squat jump) scores also show significant improvement in VRTgroup than the other two groups (p ≤ 0.001). Conclusion. Overall, our study suggests that strength training through virtual reality training protocol improves pain and sports performances than isokinetic training and other conventional trainings in university football players with chronic low back pain. 1. Introduction Football has become one of the world’s leading team events; according to FIFA’s survey, there are 265 million people actively participating in this game around the world. In- crease of the number of players also increases the number of sports injuries, which was noted especially in the lower back region (47%) [1]. Low back pain (LBP) is considered to be the major disability affecting this game and the pain is as- sociated with trunk balance control [2]. Recent studies re- port that an injury to the muscles and proprioceptors in the trunk during the sports activities affects the trunk balance control mechanisms [3]. e decline in trunk balance control may occur due to technological development, ab- normal physical activity, pathological changes, and poor training in sports. ese factors finally lead to low back pain Hindawi Evidence-Based Complementary and Alternative Medicine Volume 2020, Article ID 2981273, 10 pages https://doi.org/10.1155/2020/2981273
