Differential correlates for aerobic physical activity and resistance training: a systematic review

Worldwide, physical inactivity is a major public health concern. Both aerobic physical activity (PA) and resistance training (RT) are forms of exercise that provide numerous health benefits. The present systematic review aimed to examine the evidence among studies that have formally compared the correlates of both aerobic PA and RT in the same sample. Literature searchers were concluded in April 2022 using four common databases. Eligible studies were selected from English language peer-reviewed journals which reported at least a bivariate correlation between the correlate and aerobic PA and RT. Findings were grouped by the correlate in accordance with the capability, opportunity, motivation, behavior (COM-B) model. The analysis identified 18 studies with 16 independent samples. Overall, evidence suggest that there are many similarities between aerobic PA and RT participation. There were positive associations for both aerobic PA and RT for physical and psychological capabilities, reflective and reflexive motivation. There were mixed associations for environmental opportunities, and social opportunities had no association for aerobic PA but mixed evidence for RT. The analyses emphasized that comparative research is lacking in certain areas, principally for environmental opportunity and reflexive motivation.
