The effect of core training on dynamic balance and agility has yet to be established in literature, especially among junior athletes.
OBJECTIVE:
To investigate the effect of core training on dynamic balance and agility among Indian junior tennis players.
METHOD:
Thirty junior tennis players from various parts of Delhi and the national capital region participated in the study. The study featured a pre-test/post-test experimental design. The subjects were divided into the experimental group (mean age 15.20 0.41, mean BMI 20.23 1.54) and the control group (mean age 15.53 1.06, mean BMI 20.71 1.53). The control group performed regular training, and the experimental group followed a five-week core training program along with regular training. The subjects were evaluated with t-test for agility and the Star Excursion Balance Test (SEBT) for dynamic stability.
RESULTS:
A significant difference was found in the post-test values of agility (t-test 0.000) and dynamic balance using SEBT ((anterolateral; 0.00), (lateral; 0.02), (posterolateral; 0.00), (posterior; 0.00), (posteromedial; 0.01), (medial; 0.03), and (anteromedial; 0.03)] except in the anterior direction ( 0.23)) between the experimental and the control group. The experimental group showed a significant difference in the pre- and post-test values of the t-test and SEBT except in the anterior direction.
CONCLUSION:
Core training programs can be incorporated safely with players’ regular training to improve their dynamic balance and agility, which can eventually lead to better performance.
