Purpose: Athletes can achieve the desired sportive performance only if their physical and physiological structure suits their branch. But physical form is only one of the characteristics required for a high level of performance. Combined with motoric elements such as strength, speed, endurance, flexibility and quickness, it can positively affect performance. This research aimed to investigate the relationship between body composition and speed in adolescent athletes. Method: 53 male athletes with an average age of 14.52±.575 years, an average body weight of 64.16±8.19 kg, an average height of 1.74±.064 cm, and an average BMI of 21.06±2.25 kg.m-2 were taken into the study. "Personal Information Form," "60 Meter Sprint Test," and "Body Composition Measurement" were used as data collection tools in the research. The study data were analyzed with Pearson Correlation Test among descriptive statistics. Results: According to the data obtained from the study, a significant positive relationship (p<.05) was found between weight and height and BMI. No significant association was found between body composition and speed. Conclusion: The body composition of adolescent athletes did not play a determining role in sprint performance. However, in line with the findings of the studies in the literature, increases in BMI values are directly proportional to increases in individual body weight. This may negatively affect running-based biomotor skills such as speed, agility and acceleration.
