Does continuous walking training improve exercise capacity and physiological parameters compared to interval cycle ergometer training in men after CABG surgery?
Continuous walking training is a safe and equally effective alternative to interval cycle ergometer training for early cardiac rehabilitation in men after CABG surgery.

Walking training is a good alternative to the commonly used cycle ergometer training. It is still necessary to develop rehabilitation programs based on walking characterized by a high degree of safety and effectiveness. Aim: Application of continuous walking training as an alternative to interval cycle ergometer training in men after coronary artery bypass graft (CABG) surgery, using the 6-minute walk test (6-MWT) to determine the initial training load. Material and methods: Forty-four men aged 45 to 76 years, up to 3 months after CABG surgery, were randomly assigned to continuous training on a treadmill (study group) or interval training on a cycle ergometer (control group), performed 6 times per week (12-15 sessions). Participants underwent the treadmill exercise stress test (TEST) and 6-MWT at the begining and after completion of the rehabilitation program. Before and 3 minutes after the 6 th and 12 th training session blood lactate concentration was determined. Results: Energy expenditure in TEST increased from 4.4 to 6.3 MET in the study group and from 5.0 to 6.5 MET in the control group. Distance walked in 6-MWT increased from 420 to 519 m and from 438 to 510 m, respectively. Resting heart rate (HR) and double product (DP) decreased only in the study group as well as systolic blood pressure (SBP), HR and DP at peak exercise load in baseline TEST. Mean energy expenditure during training sessions was 2.6 MET in the study group and 2.8 MET in the control group (NS). Exercise blood lactate concentration did not exceed 2.0 mmol/l in both groups. Conclusions: Both rehabilitation programs were of similar effectiveness and their intensity did not exceed the anaerobic threshold.
Dolecińska et al. (Mié,) realizaron un ECA en cirugía de injerto de derivación de arteria coronaria (CABG) (n=44). Se evaluó el entrenamiento continuo de marcha en una cinta de correr frente al entrenamiento por intervalos en un cicloergómetro en la distancia recorrida en la prueba de marcha de 6 minutos (6-MWT) después de la intervención (p=NS). El entrenamiento continuo de marcha en una cinta fue igualmente efectivo que el entrenamiento en cicloergómetro por intervalos para mejorar la capacidad de ejercicio en hombres después de la cirugía de CABG.
