Effects of Music and Vibration on Morning Muscle Strength and Cognitive Measures in Males

概要

Athletes often compete in the morning when they are biologically weaker; normally in competition heats or quarterfinals to qualify for the finals scheduled in the evening. Some athletes may even choose to perform at submaximal levels in these qualifying rounds, especially when they are expected to perform multiple times in the same day (such as weightlifting at the Olympic Games). Gross muscular performance such as power output or force production is greater in the evening than the morning (\~3-14% variation. Similarly, time-trial performance and repeated sprint performance (RSP) a good measure of performance in team sport) is \~3 and 5 % greater in the evening than the morning. To the best of our knowledge, no study has yet investigated combined effect of vibration technology after a warm-up or music of different frequencies during testing on cognitive and physiological performance. As a daily variation in muscle strength has been widely reported in a similar population the aims of the present study are to investigate if we can improve morning muscle performance by vibration technology after a warm-up or music of different frequencies during testing on cognitive and physiological performance.
