|a Core strength training (CST) has been a popular training method in the health and fitness industry. Although strong core muscles are believed to help athletic performance, only few scientific studies have been conducted to identify the effectiveness of CST on improving athletic performance. The purpose of this study was to identify the effects of a 6-week CST program on running kinetics, lower extremity stability, and running performance in competitive and recreational runners. Twenty-eight healthy adults (age; 36.9+9.4yrs, height; 168.4+9.6cm, mass; 70.1+15.3kg) volunteered for this study. After a screening process, they were randomly assigned to one of two groups. A test-retest design was used to assess the differences between CST (n exp) and no CST (n con) on ground reaction force (GRF) measures, lower extremity stability scores, and 5000 meter (m) running performance. Tests were performed before and after 6-wks of training. Variables of the GRF were determined by calculating peak impact vertical GRF (vGRF), peak active vGRF, duration of the breaking horizontal GRF (hGRF), and duration of the propulsive hGRF as measured while running across a force plate. Lower extremity stability in three directions (anterior, posterior, and lateral) was assessed using the star excursion balance test (SEBT). Running performance was determined by 5000 m run times measured on outdoor tracks. Six 2 (pre, post) X 2 (exp, con) mixed-design ANOVAs were used to determine how CST influenced each dependent variable, p< .05. A significant interaction was found in 5000 m running time, p< .05. No significant interactions were found for other variables, p> .05. However, the experimental group showed greater improvement in SEBT score. Although CST did not significantly influence kinetic variables in the experimental group, the peak impact vGRF did not excessively increase and the peak active vGRF did not change while 5000m running performance improved. Possible limitations such as dissimilar running velocities between pre- and post-training GRF tests and the weather conditions during 5000 m run test may have affected the outcome of the study. Based on the results of this study, it is recommended performing CST to improve core muscular strength and possibly better lower extremity control. Since the participants were novice level at CST, the training may have raised awareness of an upright position or good running posture during run for the experimental group. |
