Abstract

This study aims to determine (1) the effect of giving Open Kinetic Chain Training to adolescent athletes on Quadriceps Femoris muscle strength after ACL surgery, (2) knowing the effect of giving Open Kinetic Chain Training to adult athletes on Quadriceps Femoris muscle strength after ACL surgery, (3) determine the effect of giving Close Kinetic Chain Exercises to adolescent athletes on Quadriceps Femoris muscle strength after ACL surgery, (4) determine the effect of giving Close Kinetic Chain Exercises to adult athletes on Quadriceps Femoris muscle strength after ACL surgery. This research is descriptive quantitative research. The sample was 16 post-ACL surgery patients at the Ibest Sport Physiotherapy Clinic Solo, covering the OKC and CKC exercise categories and based on the age categories of teenagers and adults. Samples were taken using purposive sampling technique. Variables in this study include: 1) Quadriceps Femoris (Y) Muscle Strength; 2) OKC Practice (X1); 3) CKC Training (X2); and 4) Age (Z). Research data was obtained from measurements using an Electromyograph (EMG). The data were analyzed using descriptive analysis and two-way Anova analysis at a confidence level of 95% or alpha = 0.05. The swimmer test includes homogeneity and normality tests. Hypothesis testing uses the two ways Anova test and t test. The results showed that from the two-way Anova analysis, the training factor Sig. equal to 0.000 < 0.05 while for the age factor the value of Sig. equal to 0.000 < 0.05. The average value of EMG results for the OKC Training group was 109.63, while for the CKC Training group it was 124.50. The tcount value is -4.515. The highest average increase in muscle strength after CKC training in the adult age category was 12.55%.
