The Effect of Fartlex Exercise on EnduranceFutsal Players for High School State 11 Jambi City

Abstract

This study aimed to investigate the effect of fartlek training on the endurance of futsal players at SMA Negeri 11 Kota Jambi. The research employed a quantitative experimental method with a one-group pretest-posttest design. The population consisted of all active futsal players at SMA Negeri 11 Kota Jambi, with 15 players selected as the sample using total sampling technique. The intervention consisted of fartlek training conducted three times per week for eight weeks, totaling 16 training sessions. Data collection was performed using the Multistage Fitness Test (Bleep Test) to measure VO₂max as an indicator of aerobic endurance capacity. Data analysis was conducted using paired sample t-test with SPSS version 27, preceded by normality and homogeneity tests.

The results showed a significant improvement in players' endurance levels. The mean pretest score was 5.20 (SD = 1.474), which increased to 6.27 (SD = 1.534) in the posttest. Statistical analysis revealed a significant difference between pretest and posttest scores (p = 0.001 < 0.05), with a t-value of 25.239 exceeding the t-table value of 1.71. The normality test using Shapiro-Wilk showed that data were normally distributed (pretest sig = 0.560; posttest sig = 0.401), and the homogeneity test confirmed homogeneous variances (sig = 0.793). These findings indicate that fartlek training significantly improved the aerobic endurance of futsal players at SMA Negeri 11 Kota Jambi. The study concludes that fartlek training can be effectively implemented as a training method to enhance futsal players' physical endurance and overall performance.
