Effects of Differing Durations and Intensities of Cardiovascular Exercise on Aversion and Feeling States in New Women Exercisers

20 previously sedentary women completed three assigned cardiovascular exercise protocols, each of varying lengths (15 to 25 min.) and intensities. No statistically significant difference was found on measures of pre to postexercise changes in feeling states, or aversion, between protocols. Findings suggest that, contrary to previous research, longer exercise sessions may not always be less acceptable to participants than shorter ones, especially when a “cool down” period is added at the end Assigned exercise durations and intensities may, however, be less likely to be associated with positive postexercise changes in feelings than self-selected amounts.
