BACKGROUND: High-energy demand for adolescent athletes not followed by adequate dietary intake can effect metabolism function in the body. The aim of this study was to investigate the effect of intakes from cow milk as an additional energy sources for metabolism (physiologic aspect), before and after performed physical activities.
METHODS: Twenty-four 18-21 years old soccer athletes, with no allergy history toward cow milk experienced soccer competition in regional level at least 3 years, with routine physical activities between 3-5 times a week. Athletes were divided randomly into three group (fresh cow milk, pasteurization milk and mineral water) that consumed for three weeks respectively. This research used Pretest-Posttest Randomized-Groups Design, with doing test twice that is pre-test (before beverages consumption) and post-test (after beverages consumption three weeks respectively). Every pre-test and post-test always doing in 2.4 km Cooper test. Before (p1) and after (p2) 2.4 km Cooper test measurements for blood lactate were performed.
RESULTS: Fresh cow milk (1.49±1.23) and pasteurization milk (1.71±0.94) gave significant effect (P<0.01) toward blood lactate before 2.4 km Cooper test (p1). After 2.4 km Cooper test (p2), only pasteurization milk (10.08±6.71) gave significant effect (P<0.05) withmblood lactate lower than mineral water (14.60±4.10) and fresh cow milk consumption (12.08±3.03).
CONCLUSIONS: Pasteurization milk gives significant effect toward physiological system, in case of blood lactate, with the enormous influence seen when prevent lactate accumulation before the 2.4 km Cooper test. And lower blood lactate after 2.4 km Cooper test may help athletes to do subsequent physical activity without feeling significant fatigue.
