EFFECTS OF PROGRESSIVE EXERCISE ON ATTENTIONAL FOCUS

To replicate 1986 work of Salmela and Ndoye on whether physical arousal from riding a stationary bicycle led to narrowing of attentional focus 17 subjects responded to a verbal 5-choice RT task while pedalling to exhaustion. Increased heart rates with increased physical stress (bicycle resistance increased) was not associated with narrowing of attention. When heart rates were 160 and 180 bpm, RTs to stimuli peripherally located to the right were slower than central ones. Further evaluation is required.
