Abstract

This study aims to examine the impact of nutrition on athlete performance when performing sports activities. This research uses qualitative descriptive research. Data collection on athletes' eating habits is often done using questionnaires to obtain accurate and systematic information on daily nutritional consumption patterns. Analyzing the relationship between nutrition and athlete performance is an important step to understanding how nutritional intake affects physical and mental abilities in sports. The population in this study was all athletes actively competing in various sports in East Nusa Tenggara and the study sample was 90 athletes. Overall, the data showed that regular eating habits, balanced nutritional intake (especially vegetables, fruits, and protein), and restriction of fast food and sugary/soda drinks contributed positively to athletes' performance. In conclusion, nutrition was shown to play an important role in improving athlete performance in East Nusa Tenggara. Research shows that a balanced consumption of carbohydrates, protein, fat, and vitamins and minerals helps athletes maintain energy, accelerate recovery, and improve endurance. Most athletes ate three meals a day, regularly ate breakfast, and consumed vegetables and fruits daily, which overall contributed positively to their performance.

Abstract

Energy transfer through the kinetic chain is a fundamental concept in explosive athletic movements. However, studies comparing the force transfer mechanisms between upper-limb and lower-limb movements, particularly in athletes in Eastern Indonesia, are still limited. This study aims to analyze and compare the biomechanical mechanisms of force transfer in the upper-lower limb kinetic chain through the Medicine Chest Pass (MCP) and Standing Broad Jump (SBJ) in SPOBNAS athletes in NTT Province. The study used a quantitative approach with a comparative and correlational design. A total of 18 athletes were divided into two groups: the MCP group (n=9) and the SBJ group (n=9). Data were collected through MCP and SBJ tests with three trials, and the best scores were recorded. Data analysis included descriptive statistics, Shapiro-Wilk normality test, Levene's homogeneity test, independent t-test, and Pearson correlation test. The results showed a significant difference between MCP and SBJ scores (p < 0.05; Cohen's d = 0.95), indicating a difference in force transfer characteristics between the two movements. Correlation analysis showed a moderate and significant positive relationship between SBJ and MCP (r = 0.47; p < 0.05; r² = 0.22). It can be concluded that MCP and SBJ represent different but interrelated kinetic chain patterns.
