Health-Related Quality Life (HRQoL) is a multidimensional way of examining health which can determine the impact of diseases, injuries, and disabilities on health. The existing literature has mixed findings on which type or combination of exercise most improves HRQoL and is focused on clinical populations with specific conditions. There is a lack of literature on the general population under 65 years old and with lack of time being the most common reason for adults not exercising, an intervention that has similar time requirements for each type of exercise needs to be performed.

Purpose: The purpose of this study was to compare the effects of aerobic exercise training (AET), resistance exercise training (RET), and a combination of aerobic and resistance exercise training (CET), on HRQoL measured by the Medical Outcomes Study 36-Item Short Form Health Survey (SF-36), specifically in 1) HRQoL in addition to 2) Physical and 3) Mental Component Summary Scores from baseline to the end of the eight-week intervention.

Methods: Inactive men and women (ages 58 � 7 years) who were overweight or obese, with elevated blood pressure were randomized to one of three 8-week exercise programs (AET, RET, CET), or a waitlist-control group. All exercise participants had the same exercise duration (time-matched) of three days per week for 60 minutes per session for a total of 180 minutes per week.

Results: Of the 69 randomized participants, 66 completed the eight-week intervention, however, all 69 were used in an intention-to-treat analysis. Compared to the CON group, the only significant improvements (mean [95% CI) from baseline to follow-up were in the AET group in the subscales of vitality (10.3 [0.7, 19.9]) and social functioning (10.3 [0.7, 19.9]). Based on the baseline and follow-up HRQoL scores, the intervention significantly improved within the AET group in the mental component summary score (4.0 [0.8, 7.3]) and the RET had no significant improvements. HRQoL. The CET group significantly improved within the overall score (6.4 [1.4, 11.4]), the physical component summary score (3.4 [0.1, 6.8]), and the mental component summary score (3.6 [0.4, 6.7]).

Conclusion: This preliminary data suggests that performing a combination of aerobic and resistance exercise for one hour, three times per week significantly improves HRQoL, however, large studies with a longer intervention are warranted.
