Biomechanical Analysis of Standing Long Jump of Junior National Football Girls with the Implementation of General Warming Up and Ramp Warm-Up

Abstract: The study investigates the biomechanical analysis of the standing long jump (SLJ) among junior national female football players, explicitly comparing the effects of general warming up (GWP) and RAMP warm-up techniques. A total of 20 participants, aged 13 to 18 from Chhattisgarh, India, were selected for this analysis using a Repeated measures design. The focus was on evaluating the sagittal plane movements related to the peak flexion of the hip joint angle (HJA) and knee joint angle (KJA) during the SLJ. Data was collected using Kinovea software to analyze the joint angles after each warm-up method. The statistical analysis employed Pearson product-moment correlation to assess relationships between the variables, with a significance level set at p<0.05. The findings revealed a strong negative correlation (-0.707) between HJA and GWP, indicating that as one variable increases, the other decreases, which is statistically significant with a p-value of 0.000. In contrast, the correlation between KJA and GWP was weak (-0.028), with a non-significant p-value of 0.907. When examining RAMP warm-up effects, a moderate negative correlation (-0.643) was found between HJA and RAMP warm-up, significant at p=0.002p=0.002. However, the KJA and RAMP warm-up relationship was weak (-0.227) and not statistically significant (p=0.337p=0.337). Overall, this study highlights essential biomechanical differences in SLJ performance influenced by different warm-up methods among junior female football players, suggesting that specific warm-up strategies affect joint angles and potentially impact jumping performance. Further research could explore these dynamics in greater detail to optimize training protocols for athletes.
