The influence of internally focus of attention during vigorous-intensity aerobic exercise for improving health status.

The purpose of this study was to examine the influence of internal focus on the ratings of perceived exertion and affect during acute high-intensity cycling exercise. Fourteen healthy male participants were recruited (22.1 ± 1.8 years). The participants performed an incremental maximal test to assess the participants' aerobic capacity and three experimental trials. In the experimental trials, the participants pedaled on a stationary cycle ergometer at 70％ V˙O_2max for 20-min in three conditions: control, internal sensory monitoring, and active self-regulation. During the 20-min cycling in each condition, the participants rated their overall and peripheral perceived exertion (RPEover, RPEperi) in 5-min intervals. Before and after 20-min cycling, participants assessed their positive engagement, negative affect, and tranquility. No significant differences in both RPEs were observed among the three conditions. In all conditions, positive engagement was higher after cycling. In addition, there were no significant differences in negative affect and tranquility. Our study suggests that internal focus does not influence perceived exertion and affects when participants conduct ACSM recommended vigorous intensity exercise. Further research needs to examine the reason that no influence of internal focus has emerged in our study.
