[Reaction of the cardiovascular system with lifting and lowering of loads].

It was investigated the influence of lifting and lowering of loads on the systolic, diastolic blood pressure and on the heart rate. Male subjects had to move 20 kg and female subjects 10 kg in different ways (2 different working frequencies and 3 back bending angles). At higher working frequencies the heart rate in men and women was in the range of the physical endurance limit. An important finding was the difference in the diastolic blood pressure response during lifting and lowering of loads with the higher working frequency in men.
