چکیده
|
The effects of oxygen uptake, heart rate and muscle activity while performing a repetitive lifting task in normal, maximum and extreme reach distances were investigated in the study. ten subjects (5 females and 5 males) of age between 22-25 years were involved in the study. the results of oxygen uptake showed an increased of 11% and 39% from normal reach to maximum and extreme reach respectively. as for heart rate the results showed an increased of 8% and 17% from normal reach to maximum and extreme reach respectively. electromyogram reading of anterior deltoid and upper trapezious muscles showed a tremendous increased of more than 80% while bicep brachii muscles showed an increase of only about 1 % from normal reach. the findings from the study showed an increased in the physiological responses when the work reach distance was increased. and lifting task, posture and load on this study developed backpain.
