摘要：This study is with a view to obtaining fundamental information necessary for the evaluation of tolerance for the upper exercise by examining vital influences of the machine speed and cranking direction in terms of heart rate (HR) and oxygen intake (V0₂), using upper body isokinetic exerciser. Subject were 3 healthy normal males averaging 22.0 years. Using Cybex upper body exerciser (UBE), experiments were made on possible influences 2 work load conditions upon vital reactions of HR and V0₂ at a constant physical work load. Twice repetition was made of each experiment. The experimental procedure was all randomized. The present syudy confirmed slight influence of the cranking direction and large vital influences of the machine speed in order of 90, 60, 30 rpm. The observed correlation of HR and V0₂ seems to make it possible to use HR which is more simply determinable, as a physiological index instead of measuring V0₂.
