The purpose of the present study was to: 1. To investigate the effects of sixteen weeks of training (aerobic/resistance) and four weeks of detraining on the cardiovascular system of men aged 70-80 yrs. 2. To investigate the effects of sixteen weeks of training (aerobic/resistance) and four weeks of detraining on the musculoskeletal system of men aged 70-80 yrs. 3. To investigate the effects of sixteen weeks of training (aerobic/resistance) and four weeks of detraining on resting anabolic hormones and the hormonal response to exercise in men aged 70-80 yrs. Methodology Thirty-two previously sedentary men aged 70-80 yrs ...

To investigate the effects of sixteen weeks of training (aerobic/resistance) and four weeks of detraining on resting anabolic hormones and the hormonal response to exercise in men aged 70-80 yrs. Methodology Thirty-two previously sedentary men aged 70-80 yrs volunteered to participate in the study. Each subject completed a medical history questionnaire, underwent a detailed medical examination and completed an incremental execise test to volitional fatigue on a cycle ergometer. Pre-training tests included body composition by dual-energy X-ray absorptiometry (DEXA), muscular strength, muscular power and rate of force development (RFD), peak oxygen consumption (V02 peak) and peak cardiac output (apeak). During a 30 min sub-maximum cycle exercise test (10 mins @40W, 50% and 70% V02 peak)a, V02 , heart rate (HR), stroke volume (SV) and blood pressure (BP) were measured after each 10 mins of work, pre-training, after 16 wk training and after four wk detraining.
