ANALISIS PERBANDINGAN KEBUGARAN JASMANI DAN INDEKS MASSA TUBUH TERHADAP INDEKS PRESTASI AKADEMIK MAHASISWA PROGRAM STUDI ILMU KEOLAHRAGAAN ANGKATAN 2023 DAN 2024

COMPARATIVE ANALYSIS OF PHYSICAL FITNESS AND INDEX BODY MASS TO ACADEMIC ACHIEVEMENT INDEX STUDENTS OF THE SPORTS SCIENCE STUDY PROGRAM CLASS OF 2023 AND 2024

Kebugaran jasmani dan status gizi merupakan aspek penting dalam mendukung kesehatan dan performa akademik mahasiswa. Penelitian ini menganalisis distribusi IMT, korelasi IMT dan VO₂max, serta pengaruh keduanya terhadap IPK pada mahasiswa Ilmu Keolahragaan Universitas Negeri Surabaya. Sebanyak 40 mahasiswa (20 angkatan 2023 dan 20 angkatan 2024) dipilih melalui stratified random sampling. IMT diukur melalui data antropometri, sementara VO₂max diukur dengan Multistage Fitness Test. Analisis data dilakukan dengan independent sample t-test dan korelasi Pearson.Hasil menunjukkan tidak ada perbedaan signifikan IMT antar angkatan (p = 0,281), namun VO₂max angkatan 2023 lebih tinggi secara signifikan (42,43 vs 35,33 ml/kg/min; p = 0,0001). Korelasi IMT dan VO₂max signifikan pada kedua angkatan (r = 0,597 dan r = 0,867). Sebaliknya, IMT dan VO₂max tidak berhubungan signifikan dengan IPK. Faktor demografis juga tidak menunjukkan pengaruh terhadap kebugaran atau prestasi akademik. IMT normal cenderung mendukung kapasitas aerobik, namun tidak secara langsung memengaruhi IPK. Temuan ini menekankan pentingnya pendekatan multidimensi yang mencakup aspek fisik, psikologis, dan strategi belajar dalam

meningkatkan performa mahasiswa.

Physical fitness and nutritional status are important aspects in supporting students' health and academic performance. This study analyzed the distribution of BMI, the correlation of BMI and VO₂max, and the effect of both on GPA in Sports Science students of the State University of Surabaya. A total of 40 students (20 batches of 2023 and 20 batches of 2024) were selected through stratified random sampling. BMI is measured through anthropometric data, while VO₂max is measured by the Multistage Fitness Test. The results showed that there was no significant difference in BMI between batches (p = 0.281), but the VO₂max of the 2023 batch was significantly higher (42.43 vs 35.33 ml/kg/min; p = 0.0001). The correlation of BMI and VO₂max was significant in both batches (r = 0.597 and r = 0.867). In contrast, BMI and VO₂max were not significantly related to GPA. Demographic factors also did not show an influence on fitness or academic achievement. Normal BMI tends to support aerobic capacity, but does not directly affect GPA. These findings emphasize the importance of a multidimensional approach that includes physical, psychological, and learning strategies aspects in Improve student performance.
