SYNERGISTIC EFFECTS OF COMPLEX TRAINING AND CLOSED KINETIC CHAIN EXERCISES ON EXPLOSIVE POWER AND LIPID PROFILE REGULATION IN COLLEGIATE SOCCER PLAYERS

The present study evaluated the combined effects of an 8-week Complex Training (CT) and Closed Kinetic Chain (CKC) intervention on physical performance and lipid profiles in 15 collegiate soccer players. Paired samples t-tests revealed significant improvements in standing broad jump (t = 3.85, p = 0.002) and medicine ball put (t = 2.31, p = 0.036), confirming enhanced explosive power. The intervention produced clinically meaningful lipid profile modifications, with a highly significant increase in HDL cholesterol (t = 4.62, p < 0.001) representing a 2.2% improvement, along with significant reductions in triglycerides (t = 2.98, p = 0.010), VLDL (t = 2.31, p = 0.036), and total cholesterol (t = 2.14, p = 0.050). However, sit-ups (t = 1.87, p = 0.082) and flexibility (t = 1.02, p = 0.324) did not change significantly, while LDL reduction (t = 2.08, p = 0.056) trended toward significance. Distribution analysis identified individual variability patterns, with persistent positive skew in medicine ball put and 40m sprint, and leptokurtic distributions in total cholesterol and LDL indicating outlier subgroups requiring individualized attention. The findings demonstrate that combined CT and CKC training concurrently enhances explosive capabilities and improves cardiovascular risk profiles.
