Abstract

Stiffness is an index for determination of elastic properties of body and its optimum range is different in various
motion patterns. The Spring-mass model is used for calculating stiffness. In this method, the whole leg is modeled
with a linear simple spring. The aim of this study is determination of lower body stiffness and evaluation of its
correlation with agility, as dominant motion pattern in racket sports. 12 national-level male racket-players (age:
25±4 years & weight: 80±7 kg) participated voluntarily in this study. Leg and vertical stiffness were measured
during running on treadmill and hopping test. Pearson’s correlation coefficients were used to examine the
relationships between stiffness and agility test records. Statistical significance was set at P< 0.05. There wasn’t
significant correlation with agility in this study. The reason could be of the contrast influence of knee and ankle
stiffness on performance. This problem requires separate evaluation of joint stiffness.

Abstract

This study investigates the impact of an anterior cruciate ligament (ACL) injury prevention program on the performance of elite female kabaddi players. Given the debilitating consequences of ACL injuries, the primary aim is to evaluate the effects of an eight-week prevention program on improving the performance of these athletes. This quasi-experimental research was conducted on 27 elite female kabaddi players (aged 18 to 24 years), who were divided into intervention and control groups. The intervention group underwent an eight-week injury prevention training program. The tests included T-test, 20-meter run, Y-balance test, flexibility, hopping, and movement screening. Data analysis was performed using Levene's test and ANCOVA. The results of the ANCOVA indicated that the intervention group scored significantly better than the control group in the Y-balance test for both the right (p=0.002) and left (p=0.001) legs, single-leg hopping (right leg: p=0.004 and left leg: p=0.001), crossover hopping for the right leg (p=0.023), and the sit-and-reach flexibility test (p=0.003). However, no significant differences were observed in the speed, agility, triple hopping, and functional movement screening (FMS) tests. Results: The findings suggest that the eight-week PEP program has a significant impact on dynamic balance for both the right and left legs, hopping (single-leg and crossover hopping for the right leg), and hamstring and lower back flexibility in elite female kabaddi players. However, it did not have a significant effect on left leg hopping, speed, agility, or FMS scores.
