Abstract

Balance control is a key factor in daily activities and learning a new skill. The aim of the present study was to investigate the relationship between arousal and activation with performance in a dynamic balance task. Thirty voluntary subjects participated (mean age: 22.1±1.23) in this study. Skin Conductance Level (SCL) as arousal index was recorded continuously during the performance of a dynamic balance task. Reaching distance was recorded on Y balance test (YBT) as performancemeasure. Pearson correlation coefficient was used to analyze the data. Results indicated a negative linear relationship between activation and performance, while arousal did not correlate with performance. Activation also predicted performance with a medium strength (r=0.57). The quality of the task was affected by activation, but not arousal. Confirmation of these data in future studies will lead to comprehension of the interaction between physiological measures and its behavioral associations in high level sport performance, especially in emotional contexts. © IDOSI Publications, 2012.
