Abstract
Purpose: The purpose of this study was to determine the effect of specific liquid ergogenic aids on performance. Performances after gatorade or coca cola was ingested were compared with performances when water was ingested. Performances after gatorade was ingested and after coca cola was ingested were also compared to each other. Physiological performance in this study was measured in terms of heart rate, oxygen consumption, and weight lost during exercise. Motor skill performance was measured by height attained in the vertical jump, speed in a movement time test, and the number of baskets made in a field goal speed test. Procedure: A total of sixty-five volunteer male students at Texas A&M University were given an Astrand-Rhyming six minute bicycle ergometer test. Each subject was a high school basketball letterman. From this group, forty subjects recorded heart rates of 168 beats per minute or lower. These forty subjects were introduced to the work bout and test procedures. As a result of problems in completing the work bout, two subjects were dropped while two other subjects were assigned as alternates. The work bout was designed to simulate a high school basketball game. Two thirty-minute halves were separated by a ten-minute half. Subjects ran on a motor driven treadmill at varying speeds from 3.5 to 11.5 miles per hour. At ten-minute intervals, beginning after three minutes of treadmill work, subjects performed a vertical jump test, movement time test, and a field goal speed test. Expired air was collected for five-minutes prior to the work bout, at half time, and immediately after the total work bout. Weight loss was calculated using pre-exercise and post-exercise measures of body weight. Heart rate was monitored every ten-minutes during the work bout. Each subject took the complete test three times, once while ingesting water, a second time while ingesting coca cola, and a third time while ingesting gatorade. The thirty-six subjects were divided into six groups, each group taking the three treatments in a different order. The analysis of variance for repeated measures technique was utilized to analyze the data. ...
