Purpose: The study was to examine the effect of lumbar stabilization exercise on back pain, physical fitness, sleep, and depression in middle-aged women who have chronic back pain. Methods: With one group pre-post test design, 18 subjects who have had more than 6 months of back pain were recruited by convenience sampling in D metropolitan area. Lumbar stabilization exercise was based on Tai Chi for back pain program developed by Lam(2003). This program was mainly focusing on strengthening lumbar stabilizing muscle for one hour per session, twice a week for 20 weeks. Degree of back pain, back pain disability, sleep, and depression were measured at three time points(pretest, 12 weeks, and 20 weeks) by a structured study questionnaire. Physical fitness variables including waist flexibility, mobility, and back muscle strength were measured three times at health promotion center located in the university hospital. Data were analyzed by frequency, descriptive statistics, and repeated measures of ANOVA. Results: Mean age of subjects was 52 years(SD = 6.4). Most of them(90%) had suffered from back pain more than one year and 67% was taking medicine to relieve their back pain. Results showed that back pain score and disability score were not significantly decreased after the exercise. On physical fitness variables, however, waist flexibility(F = 3.50, p = .04) and mobility(F = 3.31, p = .04) were improved after the exercise. Quality of sleep(F = 4.48, p = .03) was improved gradually and depression scores were also decreased(F = 3.12, p = .05) after the exercise. Conclusion: This lumbar stabilization exercise was not able to reduce chronic back pain, but could improve physical fitness and psycho-social variables for community dwelling women who have chronic back pain. Further study is needed to replicate this exercise with control group to confirm the positive effect.

Purpose: The purpose of this study was to investigate the effects of Pilates exercise on the back pain index, pelvic tilt angle, and physical fitness of pregnant women with low back pain. Methods: All study participants, all of whom had pregnancy-induced back pain, were randomly assigned to either a Pilates exercise group (PG, n = 8) or control group (CG, n = 7). The PG performed a Pilates exercise for 50 minutes three times a week for eight weeks. The back pain scale and pelvic tilt angle were measured using a visual analogue scale and angulometer, respectively. Cardiopulmonary endurance, flexibility, and grip strength were measured to examine the physical fitness. The variables were analyzed using two-way repeated-measures ANOVA with the Holm-Sidak post hoc procedure. Results: Back pain in the PG significantly decreased from 4.69 ± 1.28 to 1.06 ± 0.94, whereas the CG showed significantly increased back pain from 2.63 ± 2.20 to 4.71 ± 2.56. The left pelvic angle in the PG showed a significant decrease from 13.94 ± 3.70° to 12.29 ± 2.95°, while the CG showed a non-significant difference from 13.07 ± 4.42° to 17.37 ± 3.13°. The right pelvic angle in the PG showed a significant decrease from 13.50 ± 4.47° to 10.34 ± 3.66°, while a non-significant difference in the CG from 44 ± 4.98° to 15.30 ± 3.61° was found. These results showed that the regular participation in Pilates exercise was effective in reducing the pelvic tilt angle. In terms of physical fitness, the PG showed a significant increase in cardiopulmonary endurance, flexibility, and grip strength. However, the CG showed any significance increase in those variables. Conclusion: Eight weeks of Pilates exercise was associated with a decrease in lower back pain, a maintained or reduced pelvic tilt angle, and increased cardiopulmonary endurance, grip strength, and flexibility in pregnant woman with lumbar pain.

This study was conducted to investigate the effect of a 24-week combined exercise training program in older women with hypertension. Women with hypertension who were 70 years and older were randomized into two groups: combined exercise group (CE; n = 15) and a control group (n = 15). The CE group performed a combined exercise training program four times per week for 24 weeks and the control group did not. Five factors, including body composition (percent body fat and skeletal muscle mass), health-related physical fitness, adipocytokines (interleukin-6 [IL-6] and tumor necrosis factor-alpha [TNF-α]), kidney risk factors (glomerular filtration rate [GFR] and cystatin C), and systolic and diastolic blood pressure were measured before and after the program. The findings showed that total muscle mass, health-related physical fitness factors, and GFR increased significantly in the CE group compared to those in the control. Additionally, systolic and diastolic blood pressure and IL-6, TNF-α, and cystatin C levels in the CE group decreased significantly after the intervention. In contrast, total muscle mass decreased significantly and blood pressure remained unchanged in the control group. These results suggest that CE training may positively impact circulating levels of adipocytokines and cystatin C and improve physical fitness levels in elderly women with hypertension. Therefore, CE training helps to prevent renal disease and improve health-related physical fitness, eventually leading to a better quality of life.

Background: It has been suggested that engaging technology can empower individuals to be more proactive about their health and reduce their health risks. The aim of the present intervention was to study the effects of technology-aided testing and feedback on physical activity and biological age of employees in a middle-sized enterprise. Methods: In all, 121 employees (mean age $42{\pm}10$ years) participated in the 12-month three-arm cluster randomized trial. The fitness measurement process (Body Age) determined the participants' biological age in years. Physical activity was measured with the International Physical Activity Questionnaire Short Form. Results: Physical activity did not change during the intervention. Biological age (better fitness) improved in all groups statistically significantly (p < 0.001), but with no interaction effects. The mean changes (years) in the groups were -2.20 for the controls, e2.83 for the group receiving their biological age and feedback, and -2.31 for the group receiving their biological age, feedback, and a training computer. Conclusion: Technology-aided testing with feedback does not seem to change the amount of physical activity but may enhance physical fitness measured by biological age.

Objectives: The purpose of this study was to examine the effect of smoking on aerobic physical fitness among physical education major male university students participating in regular exercise. Methods: A group of 42 healthy male students majoring physical education were divided into two groups: non-smokers (n=$26, 20.61{\pm}2.78 $yrs) and smokers (n=16, $21.25{\pm}2.29 $ yrs). Graded exercise testing for maximal oxygen consumption ($VO_2max$) was measured by Bruce protocol. Results: $VO_2max$ was not different between non-smokers and smokers, however, exercise duration time in non-smokers was more longer than smokers'. In non-smokers, ventilatory threshold (VT) time was delayed longer than smokers (p<0.01). %VT/VEmax was significantly different between non-smokers and smokers (p<0.01). Resting heart rate (p<0.01) and recovery heart rate at 80 seconds (p<0.01) in non-smokers were significantly lower than those of smokers. The decrease in heart rate recovery in non smokers was greater than in smokers at 40(p<0.05), 60(p<0.05) and 80(p<0.01) seconds. Conclusions: These results suggest that smoking has negative effects on aerobic fitness of male university students in physical education major.
