Why the study?
Does hard physical training improve ECG findings, blood pressure, and serum markers in middle-aged sedentary men?
Does hard physical training improve ECG findings, blood pressure, and serum markers in middle-aged sedentary men?
Hard physical training in sedentary middle-aged men improves lipid profiles and ECG findings but carries a high risk of orthopaedic complications.

May support lipid and ECG benefits in middle-aged men; leaves open randomized confirmation given orthopaedic risks.
In a group of 68 middle-aged sedentary men participating for 2 months in hard physical training, 5 were initially advised against participation for medical reasons; 54 subjects completed the training program. The frequency of orthopaedic complications was high. A slight decrease of the number of abnormal ECG findings at rest and at work (premature beats and ST-changes) was found after training. The blood pressure reaction during work in relation to the heart rate response was not changed. A significant reduction of the iron and cholesterol levels in the serum occurred.
