The effects of 12-months supervised periodized training on health-related physical fitness in coronary artery disease: a randomized controlled trial

We compared the impact of a one-year periodized exercise training versus a non-periodized exercise training on health-related physical fitness (HRPF) including body composition, cardiorespiratory and muscular fitness in patients with coronary artery disease (CAD). Fifty CAD patients (60.4 +/- 9.9 years) were randomized to either a periodized training group (PG) (n = 25) or a non-periodized training group (NPG) (n = 25). Both consisted of a combined training programme, performed 3 days/week for 12 months. Thirty-six CAD patients (PG: n = 18, NPG: n = 18) successfully completed the exercise regimes. In both groups, a favourable main effect for time was evident for peak VO2, peak workload, anaerobic threshold and respiratory compensation point workloads and VO2, whole body skeletal muscle mass and quality index at 12 months. In conclusion, a periodized model is as effective as a non-periodized model in promoting increases in HRPF outcomes following a one-year intervention. These findings indicate that health-professionals can add variation to cardiac rehabilitation workouts without compromising effectiveness.

Automated summary

The study compared the impact of one-year periodized and non-periodized exercise training on health-related physical fitness in patients with coronary artery disease. The results showed that the periodized model was as effective as the non-periodized model in promoting increases in HRPF outcomes, allowing health professionals to add variation to cardiac rehabilitation workouts without compromising effectiveness.
