“…Several authors have reported a reduction of the cholesterol level after increased physical activity or training in healthy persons (12,19,29,30), while others have found no change in the value after a training period (20, 37). The plasma cholesterol concentration has been reported to be lower after physical training even in the absence of simultaneous body weight reduction (18,28,34). On training of patients with earlier cardiac infarction Bjorntorp et al (6) found no significant decrease of the plasma cholesterol, and neither was any significant reduction noted in the present series.…”
