Abstract

Overhead passing is a fundamental skill in volleyball that significantly influences game performance. Modified ball training is often used to enhance players' motor skills, but its effectiveness compared to non-modified training remains underexplored. This study aims to analyze the effect of modified and non-modified training on motor skills and its impact on overhead passing ability in the volleyball team of SMP Negeri 23 Kerinci. The study employs a quantitative experimental design with 16 volleyball players divided into two groups: modified ball training and non-modified training. Normality was tested using the Shapiro-Wilk test, and since the data were not normally distributed, the Mann-Whitney test and multiple linear regression were used for statistical analysis. The results indicate that modified ball training significantly improves overhead passing ability compared to non-modified training (p = 0.014). Players with higher motor skills showed greater improvement than those with lower motor skills. Regression analysis revealed that motor skills positively influence overhead passing (β = 0.506, p = 0.009), while modified training has a negative but significant effect (β = -0.564, p = 0.005), suggesting its effectiveness for players with higher motor skills. Coaches are encouraged to implement modified training to enhance volleyball players' technical skills.

Abstract

This study examined whether a four-week progressive upper-body resistance training program improves straight punch frequency-speed in club-level pencak silat athletes, for whom sport-specific upper-limb training evidence is scarce. A one-group pretest-posttest quasi-experimental design was used. Twelve athletes (aged 14 years or over, at least one year of training experience, injury-free) were purposively selected from 65 active club members in Padang, Indonesia. Participants completed 16 supervised sessions (four per week for four weeks) combining progressively loaded bench press, shoulder press and triceps extension (60% to 75-80% 1RM) with explosive transfer work (explosive push-ups, medicine-ball chest passes and throws, plyometric push-ups). The outcome measure was the number of legal straight punches delivered to a bag in a maximal 10 s effort, scored by the same rater under an identical protocol at both time points. Both distributions were normal (Shapiro-Wilk p = 0.561 and p = 0.190) and were analysed with a paired-samples t test (α = 0.05). Punch frequency rose from 46.33 ± 5.84 to 54.00 ± 3.52 punches/10 s, a mean gain of 7.67 punches (16.6%; 95% CI 5.25 to 10.08), t(11) = 6.99, p < 0.001, Cohen's dz = 2.02 (95% CI 1.00 to 3.01); between-athlete variability also fell significantly (Pitman-Morgan t(10) = 2.67, p = 0.024). Progressively loaded upper-body training with explosive transfer work therefore appears to be a practical, low-cost way of raising punch frequency-speed in pencak silat, most plausibly through early neural adaptation. Because the design was uncontrolled and the sample small, these findings are preliminary and require confirmation in randomised controlled trials.
