- Abstract
Twenty healthy young women participated in thislaboratory research. They completed the Exercise Induced Inventory (EFI - Gauvin & Rejeski, 1993) before, immediately after, and 15-wins after a 20-minute progressive treadmill exercise during which they ran for 5-wins at 50%, 60%, 70% and 80% of their maximal heart rate reserve (MHRR). Before, during every stage of exercise, and twice after exercise, the participants were asked to continuously identify a letter in a specific position in unexpected words - presented in 8 second intervals over a period of three minutes - while their information processing speed (IPS,) was gauged. Results showed that IPS was shortest when participants ran at 80% of MHRR, suggesting that quick mental choices are made easier under heightened levels of arousal. No changes in affect (transient mood states) from pre- to post-exercise were seen. These findings appear to support the circumplex model of affect claiming that affective valence is invariant (unchanged) when distracting mental tasks are undertaken during exercise.
