Abstract
This study aimed to examine and compare the effects of squat training with a constant knee angle and with different knee angles on acceleration ability in young female sprinters. In Study 1, twelve purposively selected female athletes aged 14–16 years performed all three conditions in a randomized and counterbalanced order, with a one-week interval between each condition. Data were analyzed using two-way ANOVA with repeated measures. The results showed that the 30-meter sprint time in Conditions 2 and 3 was significantly better than in Condition 1, with Condition 3 also significantly better than Condition 2. Similarly, sprint velocity from the start to 30 meters in Conditions 2 and 3 was significantly greater than in Condition 1, and Condition 3 was significantly greater than Condition 2 (p < .05). In Study 2, thirty purposively selected participants were divided into two groups: the first trained with a constant knee angle, and the second trained with different knee angles for six weeks. Data were analyzed using the t-test. The results showed no significant difference in 10-meter sprint time between the two groups; however, the second group had significantly better sprint times at 20 and 30 meters. For sprint velocity, there was no significant difference from the start to 10 meters, but the second group recorded significantly greater velocity from the start to 20 meters and from the start to 30 meters than the first group (p < .05). These findings indicate that squat training with different knee angles can improve the acceleration ability of young female sprinters more effectively than squat training with a constant knee angle.
