Background: Men with prostate cancer (PCa) may be referred to cardiac rehabilitation (CR) following a significant cardiac event, but it is unknown if these men have different effects of CR from men without a history of PCa. Purpose: To compare the effect of CR on cardiorespiratory fitness (VO2peak), body fat percentage, and body mass index in men with and without a history of PCa. Methods: CR participants with PCa were retrospectively compared with a cohort matched on age, clinical indication for CR, and date of referral to the CR program. Participants completed the standardized CR program at the Toronto Rehabilitation Institute, including 1 weekly supervised group session and 4 additional weekly home sessions including aerobic and resistance training for 26 weeks. Results: Twenty-seven (n = 27) men with PCa were identified and matched 1∶1 with controls. VO2peak increased in the PCa group (16.9 [5.1]–19.6 [6.2] mL·kg−1·min−1; Δ 2.7 mL·kg−1·min−1, P < .05) and in the control group (16.4 [4.2]–20.2 [5.8] mL·kg−1·min−1; Δ 3.8 mL·kg−1·min−1, P < .05) as a result of engaging in CR. There were no significant between-group differences in the postintervention outcomes (P > .05). Conclusions: Men with and without PCa experience comparable benefits following CR completion.

Background:

Women’s understanding of “moderate-intensity” physical activity (MPA) as presented in the media is not well-understood. This study assessed whether women who are presented a mass-media message about MPA can demonstrate a moderate-intensity walking pace without practicing this pace first.

Methods:

Insufficiently active women (n = 75, age 40 ± 12 years, 76% White) were shown a mass-media description of a MPA recommendation. Forty-one were randomized to also practice a moderate-intensity (55%−70% of maximum heart rate) walk. One month later, participants were asked to demonstrate a 10-minute moderate-intensity walk. Groups were compared on the proportion of participants who walked ≥10 minutes at a moderate intensity.

Results:

At posttest, more participants who received practice at baseline walked at a moderate-intensity ≥10 minutes than those who received no practice (P < .05).

Conclusion:

To understand MPA, it is not enough to simply hear and read a description of MPA. It is essential to practice MPA.
