This systematic review and meta-analysis of non-randomized clinical trials aimed to explore functional correction training after Functional Movement Screen (FMS™) and the effects of training on injuries of athletes and to determine whether it can improve the general athletic ability of athletes. Articles were included if the independent variable was functional correction training after FMS™ and if the dependent variables were athletes’ sports injury risk and general athletic ability. Data conditions were sample size, mean, standard deviation, number of athletes with sports injuries, and model asymmetry after intervention in the experimental group and control group. The subjects were athletes. A functional correction plan was used as the intervention for the experimental group, and the control group only performed daily training. Exclusion criteria were as follows: conference abstracts or non-peer-reviewed papers; cross-sectional, retrospective, or prospective cohort study design; and non-athletes. The following data were extracted from the original reports: authors, year, and publication; country; sample characteristics (sample size, age, sex); functional correction training program; daily training program; and main results (average value, standard deviation), number of athletes with sports injuries, and model asymmetry after the intervention in the experimental group and in the control group.
