Physical fitness is an
essential requirement for basketball athletes, enabling them to engage in
training and competition effectively and efficiently. Several factors influence
physical fitness, including body composition and nutrient intake. Body composition
significantly impacts the performance of basketball athletes, with
anthropometric measurements affecting hand grip strength, crucial for ball
handling and throwing. Optimal nutrient intake is essential for maximizing
athletic performance. This study aims to investigate the correlation between
body composition and macronutrient intake on physical fitness. This
quantitative study employed a cross-sectional design. Participants included 32
male and 16 female athletes from the UNESA Basketball Team. Body composition
was measured using Bioelectrical Impedance Analysis (BIA), macronutrient intake
was assessed using the Semi-Quantitative Food Frequency Questionnaire (SQ-FFQ),
and physical fitness was evaluated using the Multi-Stage Fitness Test (MFT).
The relationship between variables was analyzed using Pearson and Spearman Rank
correlation tests. The findings revealed a significant correlation between body
fat percentage (p = 0.001), subcutaneous fat (p = 0.000), and muscle mass (p =
0.000) with physical fitness. Additionally, a significant correlation was found
between energy intake (p = 0.002), protein intake (p = 0.000), and fat intake
(p = 0.001) with physical fitness. However, carbohydrate intake (p = 0.117)
showed no significant correlation with physical fitness. This study concludes
that body composition, specifically fat percentage and muscle mass, has a
significant correlation on physical fitness. Energy, protein, and fat intake
are significantly correlated to physical fitness, while carbohydrate intake
does not show a significant correlation.
