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.

In this paper, a study was conducted to estimate the maximum muscle strength which is a standard for selecting exercise intensity in weight training. We designed a device that estimates the muscle fatigue from the EMG signal, expecting to show a correlation between peak muscle strength and fatigue. Curl - Dumbbell was performed using a 4 kg dumbbell and the frequency change of the EMG was observed. At this time, the designed device acquires the signal using the MCU and finally Matlab was used to confirm the change in the center frequency value. The results of 10 subjects were analyzed using SPSS regression analysis. The statistical results showed a correlation of $R^2$ 0.583 and Significant probability of 0.010, and the relation of Y = 8.144-2.097 (slope (MDF)) was obtained. In conclusion, if the wearable device is manufactured in the form of a wearable device and the user can recommend the exercise intensity, the system will be able to retry the more efficient exercise.

[Purpose] The present study investigated the effect of endurance exercise with blood flow restriction (BFR) performed at either 25% maximal oxygen uptake (${\dot{V}}O_2$ max) or 40% ${\dot{V}}O_2$ max) on muscle oxygenation, energy metabolism, and endocrine responses. [Methods] Ten males were recruited in the present study. The subjects performed three trials: (1) endurance exercise at 40% ${\dot{V}}O_2$ max without BFR (NBFR40), (2) endurance exercise at 25% ${\dot{V}}O_2$ max with BFR (BFR25), and (3) endurance exercise at 40% ${\dot{V}}O_2$ max with BFR (BFR40). The exercises were performed for 15 min during which the pedaling frequency was set at 70 rpm. In BFR25 and BFR40, 2 min of pressure phase (equivalent to 160 mmHg) followed by 1 min of release phase were repeated five times (5 × 3 min) throughout 15 minutes of exercise. During exercise, muscle oxygenation and concentration of respiratory gases were measured. The blood samples were collected before exercise, immediately after 15 min of exercise, and at 15, 30, and 60 minutes after completion of exercise. [Results] Deoxygenated hemoglobin (deoxy-Hb) level during exercise was significantly higher with BFR25 and BFR40 than that with NBFR40. BFR40 showed significantly higher total-hemoglobin (total-Hb) than NBFR40 during 2 min of pressure phase. Moreover, exercise-induced lactate elevation and pH reduction were significantly augmented in BFR40, with concomitant increase in serum cortisol concentration after exercise. Carbohydrate (CHO) oxidation was significantly higher with BFR40 than that with NBFR40 and BFR25, whereas fat oxidation was lower with BFR40. [Conclusion] Deoxy-Hb and total Hb levels were significantly increased during 15 min of pedaling exercise in BFR25 and BFR40, indicating augmented local hypoxia and blood volume (blood perfusion) in the muscle. Moreover, low-and moderate-intensity exercise with BFR facilitated CHO oxidation.

The purpose of this study was to investigate the difference in dietary attitudes, dietary behaviors and health-related lifestyles among Korean college students (392 males, 808 females) participating in a web class of nutrition education. This cross-sectional survey was conducted by a self-administered questionnaire and data was analyzed by SPSS program. Most female subjects with weight-control attempt had eating habit problems such as overeating and food jags. The female subjects with weight-control attempt showed significantly higher rate of skipping dinner compared to those without weight-control attempt. As for frequency of exercise, the subjects with weight-control attempt exercised more frequently compared to those without weight-control attempt. In subjects, weight-control attempt was significantly associated with exercise. Nutrient adequacy ratio and mean adequacy ratio of the subjects with weight-control attempt were significantly lower compared to those without weight-control attempt. These results suggest that skipping dinner or exercise might be used as weight-control methods in Korean college female students participating in a nutrition education class via the internet.
