Abstract

Trail running has physiological characteristics that differ from conventional running due to variations in elevation and unstable terrain. This study aimed to analyze the relationships between vital lung capacity, leg muscle power, and VO₂max in trail running athletes. A cross-sectional correlational design was used with 60 trail running athletes from clubs in Bandung, selected through purposive sampling. Vital lung capacity was measured using a spirometer, leg muscle power using the vertical jump test, and VO₂max using the 15-minute Balke test. Data were analyzed using Pearson correlation and multiple linear regression. Vital lung capacity showed a very strong positive relationship with VO₂max (r = 0.904; p < 0.001), while leg muscle power showed a strong positive relationship with VO₂max (r = 0.801; p < 0.001). Both variables were simultaneously and significantly associated with VO₂max (F(2,57) = 142.019; p < 0.001; R² = 0.833). These findings indicate an association between respiratory capacity, lower-limb neuromuscular capacity, and aerobic capacity in trail running athletes. The cross-sectional design limits the interpretation of the findings to associations between variables and does not establish causal relationships.

Abstract

Penelitian ini bertujuan untuk mengetahui tingkat self-efficacy, tingkat prestasi, serta pengaruh self-efficacy terhadap prestasi atlet Taekwondo Kyorugi DKI Jakarta. Metode penelitian menggunakan kuantitatif korelasional dengan melibatkan 100 atlet Taekwondo Kyorugi DKI Jakarta yang dipilih melalui teknik purposive sampling. Data self-efficacy dikumpulkan menggunakan instrumen Self-efficacy Scale (SES), sedangkan data prestasi diperoleh dari rekap perolehan medali atlet periode 2023-2026. Karena data tidak berdistribusi normal (uji Kolmogorov-Smirnov dan Shapiro-Wilk), analisis hubungan menggunakan korelasi Spearman’s rho dan regresi sederhana. Hasil menunjukkan mayoritas atlet (60,00%) berada pada kategori self-efficacy sedang dan 28,00% kategori tinggi, dengan rata-rata skor self-efficacy sebesar 71,30. Atlet meraih rata-rata 11,88 medali selama periode penelitian. Uji korelasi Spearman’s rho menunjukkan hubungan sangat lemah tidak signifikan antara self-efficacy dan prestasi atlet (rho = 0,018; p = 0,862), diperkuat oleh hasil regresi sederhana yang juga tidak signifikan (R Square = 0,001; F = 0,093; p = 0,760). Simpulannya, self-efficacy tidak berpengaruh signifikan terhadap prestasi atlet Taekwondo Kyorugi DKI Jakarta, kemungkinan karena ketidaksesuaian (nonconcordance) antara pengukuran self-efficacy pada satu titik waktu dengan data prestasi yang bersifat akumulatif jangka panjang, serta dominannya faktor fisik, teknik, dan taktik. Meskipun demikian, penguatan aspek psikologis tetap relevan sebagai bagian program pembinaan prestasi atlet, khususnya bagi atlet dengan self-efficacy rendah.
