Abstract

Dancesport, as a discipline that combines artistic performance and competitive sport, requires technical mastery and strong psychological readiness. Achievement motivation becomes a critical performance determinant, shaped by internal and external factors. This study analyzed the influence of parental support and self-confidence on the achievement motivation of North Sumatra dancesport athletes competing at PON XXI Aceh–North Sumatra 2024. A quantitative approach with an ex post facto survey design was applied. The sample consisted of 10 randomly selected athletes, ensuring that all eligible participants were included in the study. Data were collected using validated Likert-scale questionnaires, and instrument validity was confirmed through expert review, pilot testing, and Cronbach’s Alpha reliability (all > 0.70). Data analysis was conducted using simple and multiple regression with SPSS 26. The results showed that parental support significantly influenced achievement motivation (F = 7.842; p = 0.012), self-confidence also had a significant positive effect (F = 18.074; p = 0.002), and their combination significantly contributed to motivation (F = 6.215; p = 0.028), explaining 64.7% of the variance. These findings conclude that the synergy of external support and internal psychological capital shapes achievement motivation in dancesport. The practical implication is that athlete development programs must integrate parental involvement with structured confidence-building strategies. Theoretically, this study contributes to integrating social support theory and achievement motivation theory in the Indonesian sports context, emphasizing the role of both social and psychological dimensions in athlete development.

Abstract

The necessity of power in volleyball is to support the game's technique. Volleyball players' leg muscles must be strong enough to sustain techniques like smashes, blocks, and serves. Proper workouts, such as plyometric exercises, should reinforce the importance of muscular leg power. This study aims to determine the impact of plyometric side-to-side box shuffle and leap to box exercises on leg muscle power and determine which workouts are more successful in developing volleyball participants' limb muscular explosiveness. This is an experimental study with a "Two Groups Prettest Posttest Design" as the research design. The sample size for this study was up to 30 female athletes, with Purposive Sampling being employed as the sampling strategy. The samples were randomly split into two groups. The vertical leap test was utilized to determine the strength of the limb muscles in this research. Normality tests, homogeneity tests, and t-tests are used in data analysis. The results revealed a sig value of 0.918, indicating a difference in enhancing muscular leg strength in footballers between side-to-side box shuffle and leap to box workouts. Jump to box training improves muscular leg strength more than side-to-side box shuffle training, with a ratio of rises of 22.00 percent and 16.73 percent, respectively.
