Description

<p>For the present research, a study was conducted with rapidly growing late adolescent high school athletes with the aim of understanding basic data such as pre- and post- exercise physical measurements, body metabolism, and examining the effects of fatty acid intake on exercise performance. The participants (n=24; male=11, female=13) in the study were first- and second-year high school students who belong to their school’s basketball club.</p><p>Data collection in the study consisted of the participant’s physical measurements and blood test, and their Rating of Perceived Exertion (RPE) before and after exercise. The exercise intensity was calculated using the Metabolic Equivalents (METs) of daily club activities. The participants completed a dietary intake survey using Brief-type self-administered Diet History Questionnaire for 15-years-olds (BDHQ15y).The participants also completed a physical measurements and blood test, and a Rate of Perceived Exertion (RPE) before and after exercise. We investigated the effect of a 2-week regiment of food containing medium-chain triglycerides (MCT) and long-chain triglycerides (LCT).</p><p>Results of the study showed significantly higher values Creatine Kinase (CK) after the 2-week period. Participants also showed no significant difference between males and females students before and after. No severe adverse effects were observed.</p><p>In conclusion, this study suggests that MCT intake up to 6 g/day is safe for high school students. Further study will be needed to show it’s effectiveness in reducing muscle fatigue.</p>
