This PTQ article reviews scientific literature on concurrent training and examines whether combining aerobic and resistance exercise has meaningful impacts on performance. Visit the NSCA online to read more about personal training.

This review analyzes relevant variables involved in acute interference effects of concurrent training (CT) sessions of aerobic exercise followed by strength exercises. The aerobic exercise intensity, mode, volume, duration of recovery interval between exercises, muscle groups involved, and utilization of ergogenic aids are the variables identified in this review. High-intensity interval aerobic exercises result in more pronounced negative effects on strength-endurance exercise but not in maximal strength. Cycling results in more negative effects on strength endurance performance exercise than running. A 4-hour to 8-hour recovery interval seems to be enough to avoid interference on strength-endurance performance. Reduction in strength-endurance performance is located in muscle groups involved in both exercises. Low aerobic exercise volume (3 km) with; 18 minutes of duration does not diminish strength endurance, whereas higher volumes (5 and 7 km) with ;30 and ;42 minutes of duration, respectively, generate impairments. Caffeine, carbohydrate, and beta-alanine are not able to revert the deleterious effect on strength-endurance performance, whereas creatine and capsaicin analog supplementation are. Thus, these variables must be taken into consideration to prescribe and organize a CT session. This information may help coaches to organize exercise sessions that minimize or avoid the impairment in strength performance after aerobic exercises.

This article will explain the interference effect and provide a rationale for why low-intensity steady-state (LISS) cardiovascular training may be a useful tool for those interested in improving their body composition.

High-intensity strength training paired with explosive, high-velocity movements is suggested to enhance endurance performance. It is recommended that a practical approach be taken when implementing this model of strength training, which would involve a thorough preparatory period.
