PENGARUH FARTLEK TRAINING TERHADAP PENINGKATAN KEKUATAN OTOT TUNGKAI PADA CALON SISWA DI M22TC

Background: Physical condition is an important factor in the success of
prospective civil service students, especially in facing physical fitness tests. One of the main components is leg muscle strength, which plays a role in activities such as running, jumping, and maintaining body balance. However, there are still many prospective students who have less than optimal leg muscle strength due to undirected training methods, one method that can be used is fartlek training, which is training with variations in speed from low to high intensity. Purpose: The purpose of this study was to determine the effect of fartlek training on increasing leg muscle strength in prospective civil service students at M2TC. Method: This study used a quantitative approach with a pretest-posttest design on 15 prospective civil service students at M2TC who were selected by purposive sampling. Data were analyzed using the Shapiro-Wilk normality test and continued with a paired sample T-Test to determine the effect of training. Results: The results showed that the data were normally distributed (p = 0.459 > 0.05). Paired sample T-Test showed a significant difference between pretest and posttest scores (p<0.001), with the average increasing from 136 to 187. Conclusion: Fartlek training has been shown to have a significant effect on increasing leg muscle strength in prospective civil service students at M2TC. This training is able to increase leg muscle strength through physiological adaptation and variations in exercise intensity.
