Preliminary evaluation of a 10-wk. resistance and cardiovascular exercise protocol on physiological and psychological measures for a sample of older women.

A preliminary 10-wk. study was conducted to determine the effect a combined strength and cardiovascular exercise protocol had on both physiological and psychological change in 17 older (M age = 66.8 yr.), formerly sedentary women. The protocol was associated with better adherence than typically found for new and returning exercisers. Significant improvements over 10 wk. were found on Body Mass Index, body fat, resting heart rate, and balance. Significant, positive changes in mean ratings were also found on Physical Self-concept, Total Mood Disturbance, Depression, and Fatigue (small to moderate treatment effect sizes). Although no significant changes were found for rated Tension, Vigor, Anger, and Confusion, mean changes were in the desired direction and rated Tension showed a moderate effect size. The need for replication, including a control group and follow-up, plus continued research on exercise protocols both well-tolerated and effective for older individuals and other specific groups, were discussed.
