This study was designed to investigate the effects of a 6-week progressive exercise, mainly calisthenics, and education for low back pain on muscular endurance, flexibility, and self-perceived pain in low back patients. Eighteen female patients, aged 48±6.84 years, were volunteered to participate in the study as subjects. Standing height, body weight, percent body fat, waist-hip ratio(WHR), sit-and-reach trunk extension, sit-up, back sit-up, and pain ratings were measured in pre test. Upon the completion of the pre test, they went through the six weeks of interventions composed of progressive exercise and education for the first four weeks and the exercise only for the last two weeks. Then, they were tested in the post test by the same manner as the pre test. The results of pre and post test were compared by the paired t-test. The main results of the present study were as fellows: First, there were no significant changes by the interventions in body weight and WHR, whereas percent body fat were reduced significantly by the interventions. Second, flexibility and muscular endurance were enhanced significantly by the interventions. Third, self-perceived low back pain ratings and perceive ratings of pain in the daily activities were reduced significantly by the six weeks of interventions. It was concluded that low back pain would be relieved by the progressive exercise and education for low back pain, and that the interventions would be helpful to prevent additional injuries by increasing the flexibility and muscular endurance.

The purpose of this study was to determine heart rate (HR), ratings of perceived exertion (RPE) and oxygen uptake (Vo2) at the anaerobic threshold (AT) in two different exercise modalities, cycle ergometer and treadmil exercise (running). Subjects were 13 women patients with coronary heart disease. All sub-maximal and maximal Vo2 values but Vo2 at the AT for women were significantly higher in treadmill exercise than cycle ergometer. Submaximal and maximal HR values were not significantly different between the two exercise modalities. However, mean RPE values at the AT were significantly higher in cycle ergometer than treadmill exercise. We suggest that appropriate HR values in exercise training should be the same in cycling and treadmill exercise. while RPE values should be 1 or 2 higher in cycling than running.
