Abstract

Background Problem: Nutrition plays an important role in fitness, yet there is limited understanding of how non-sporting students, particularly nutrition students, manage their fitness. This study fills the gap by exploring the relationship between physical activity, dietary habits, and fitness in this group. Research Objective: This study aims to examine the fitness profile of female undergraduate nutrition students and explore the factors associated with fitness such as physical activity level (PAL), nutritional status, and diet. Methods: To answer the research objective, a cross-sectional design was conducted, involving 114 healthy female students, aged 18-20 years old. Respondents were selected by using proportional random sampling, which enabled equal representation of each class in the study. Exclusion criteria: students have chronic disease or condition affecting physical fitness. Physical fitness was assessed using the Harvard Step Test, PAL was measured via an online self-administered IPAQ, nutritional status was assessed using a body mass index (BMI) calculation, and dietary data (energy and iron intakes) was assessed using 2x24 non-consecutive food records. Chi-squares or Fisher Exact tests were done to analyse the association between physical fitness and other variables. Finding and Result: We found that almost all of our respondents were at poor levels of physical fitness. There was no significant association between physical fitness and other variables such as PAL, BMI, and diet. Conclusion: This research supported previous findings that college students in health majors have poor fitness. Future studies should explore additional factors such as physiological stress, sleep pattern, or socio-economic status that may impact the fitness level of health-major students.

Abstract

This study aimed to describe the kinematic characteristics of front kick speed in regional level Pencak Silat athletes from South Lampung Regency preparing for the 10th Lampung Provincial Sports Week (PORPROV X) in 2026. A quantitative descriptive approach was employed involving ten athletes (six males and four females) who were actively participating in a centralized training program. Front kick performance was recorded using a high-speed Fujifilm X-T4 camera at 240 frames per second with a 50 mm focal length lens to minimize perspective distortion. The recorded videos were analyzed using Kinovea 2025.1.1 software through two-dimensional kinematic analysis. The measured variables included kick displacement, execution time, and average kick speed. The results showed that male athletes achieved higher average front kick speeds (2.75 m/s) than female athletes (2.33 m/s), primarily due to shorter execution times rather than greater displacement. Overall, performance was characterized by adequate movement range but lower temporal efficiency compared to values reported in elite athletes, indicating that execution time is a key determinant of front kick speed at the regional level. This study contributes to the biomechanics of Pencak Silat by providing empirical kinematic data at the provincial level and identifying execution time as a primary performance-limiting factor. These findings offer a biomechanical basis for targeted training interventions focusing on neuromuscular coordination, explosive strength, and movement acceleration. It can be concluded that improving temporal efficiency is critical to enhancing front kick performance. Future studies should incorporate larger samples and three-dimensional analysis for a more comprehensive understanding.

Abstract

Mahasiswa semester awal merupakan kelompok yang rentan terhadap stres dan tekanan psikologis akibat tingginya beban akademik serta proses adaptasi terhadap lingkungan perguruan tinggi. Penelitian ini bertujuan untuk menganalisis efektivitas latihan fisik terstruktur terhadap tingkat stres dan beban akademik mahasiswa di Institut Teknologi Sumatera. Penelitian ini menggunakan desain eksperimen semu dengan pendekatan pretest–posttest control group design. Sebanyak 120 mahasiswa dibagi menjadi kelompok eksperimen dan kelompok kontrol. Kelompok eksperimen mengikuti program latihan fisik intensitas ringan – sedang selama duabelas minggu dengan frekuensi tiga kali per minggu, sedangkan kelompok kontrol menjalani aktivitas rutin tanpa intervensi. Hasil penelitian menunjukkan bahwa kelompok eksperimen mengalami penurunan rerata skor beban akademik dari 72,4 ± 8,6 menjadi 64,1 ± 7,9 serta penurunan tingkat stres dari 21,6 ± 4,9 menjadi 15,2 ± 4,3. Sebaliknya, kelompok kontrol hanya menunjukkan perubahan kecil pada beban akademik (71,8 ± 8,2 menjadi 70,5 ± 8,4) dan tingkat stres (21,1 ± 5,1 menjadi 20,3 ± 5,0). Temuan ini menunjukkan bahwa latihan fisik terstruktur efektif dalam menurunkan stres dan persepsi beban akademik mahasiswa semester awal. Penelitian ini merekomendasikan integrasi latihan fisik sebagai strategi promotif kesehatan mental di perguruan tinggi.
