Purpose: The purpose of this study was to review the effects of physical activity on musculoskeletal outcomes in older Koreans. Methods: Experimental studies were retrieved from the search engines (PubMed, CINAHL, PsycINFO, Cochrane, RISS, KISS, and KoreaMed). The selected studies for analysis were 27 articles of musculoskeletal outcomes (gait, muscle strength, flexibility, balance, grip strength, endurance, body fat, and weight) from 515 articles. Results: The most common type of physical activity was a resistance exercise. There were significant improvements in gait (71.4%), muscle strength (86.7%), flexibility (63.6%), balance (72.2%), grip strength (71.4%), endurance (71.4%), body fat (57.1%), and weight (28.6%). The activity programs that apply over 150 minutes a week showed greater improvement of 69.5% than 65.0% from those did not meet the guidelines totally. Conclusion: Based on the review, we conclude that regular physical activity in the elderly may improve the musculoskeletal outcomes. To be more effective programs, it is necessary to meet the guidelines of 150 minutes a week or 30 minutes of moderate-intensity activities on 5 days per week for the elderly.

The purpose of this study was to investigate the effects of exercise therapy to oldwomen's muscle strength, flexibility and IADL. To identify the effect of exercise therapy on oldwomen's muscle strength, flexibility and IADL, this study attempted to determine grip strength, back strength, leg strength, flexibility of upper and low(flexion, extension, abduction), flexibility of trunk(flexion, extension) and IADL, using dynamometer, goniometer and Geriatric center IADL, for 34 female. Thirty-four subjects participating in this study consisted of A group(from sixty-five to sixty-nine, eleven person), B group(from seventy to seventy-four, twelve person), C group(over seventy-five years old, eleven person). Data from the findings of this experiment were computed for and standard deviation by using repeated measurement of MINI TAB. As a result, the following conclusion was drawn : 1. Subject group showed significantly higher scores on effect of exercise between three age group after regular exercise. 2. Subject group showed significantly higher scores on muscle strength(grip strength, back strength, leg strength) and there is a difference between three age group after regular exercise of muscle strength. 3. Subject group showed significantly higher scores on flexibility (upper, lower, trunk) and there is a difference between three age group after regular exercise of flexibility. 4. Subject group showed significantly higher scores on IADL(Instrumental activities of daily living) and there is a difference between three age group after regular exercise. As a result of this study, the effect of exercise training program had improved muscle strength, ROM (range of motion) of joint, IADL. Thus exercise training program could be beneficially applied for the prevention of disability and promotion of health and wellbeing in the aged easily and safely.

Braincomputer interface (BCI) technology is making advances in the field of humancomputer interaction (HCI). To improve the BCI technology, we study the changes in the electroencephalogram (EEG) signals for six levels of grip strength: 10%, 20%, 40%, 50%, 70%, and 80% of the maximum voluntary contraction (MVC). The measured EEG data are categorized into three classes: Weak, Medium, and Strong. Features are then extracted using power spectrum analysis and multiclass-common spatial pattern (multiclass-CSP). Feature datasets are classified using a support vector machine (SVM). The accuracy rate is higher for the Strong class than the other classes.

Most of carrying works have been performed in almost all production process, conveyer objects, machine equipment and work method. Then, they are made by unfitted design which doesn't consider physical condition of workers. So, it causes them to bring about forceful motion. This study investigated the back power for what difference between lumbar bending angle and back power by selecting 21 male aged 22∼30 years old. Lumbar angle were shared each 30, 60, 90 degrees and measured. The results of this study was that as lumbar angle was increasing, back power was decreased and were very significant differences for angles respectively. Besides. sample correlation coefficients were calculated in order to analyze the relationship between back power, anthropometric dimensions and grip strength. Back power was correlated with weight, arm length, hand length, breadth of palm, breadth of lower arm, breadth of wrist and left-right grip strength.

This study was conducted to induce muscle loss using dexametasone and then use the extract to determine its effectiveness in a muscle loss animal model. Animal experimental groups were divided by five groups. Changes in the weight of the animals were measured for a total of 5 weeks. After animal sacrifice, muscle mass was measured, and animal behavior evaluation was conducted using grip strength test and pole test. The expression levels of MAFbx protein was measured using muscle samples. Oral administration of Fomes fomentarius extract was effective in suppressing muscle atropy and increasing muscle, which was confirmed through animal behavior evaluation and muscle-related protein expression.

We can establish hypothesis that the grip strength of the CTDs gorup is weaker, SNAP is lower, and NCV is stower than the normal subjects. This paper is to drive out the characteristics of pinch strength and EMG for subjects G1 and G2 who are supposed to be in CTDs and the normal group. The results are as follows: (1) The pinch strength of the CTDs group is weaker than the normal group. It is remarkably decrease in the afternoon for G2 group. (2) There was no significant difference on SNAP among three groups. (3) There was significant difference on NCV among three groups.

This study was done to investigate levels of physical fitness, self efficacy(SE), instrumental activities of daily living(IADL), and quality of life (QL), and their relationships among the elderly Data were collected from 47 noninstitutionalized elderly dwell-ing in their own homes and 43 institutionalized elderly living in homes for older people. The ages of the subjects were 65 years and over. The data were col lected from January 20th to February 20th, 1995. Physical fitness was measured with T.K. K dyna mometer, grip dynamometer, stop watch, and Purdue pegboard. Structured questionnaires developed by Kim by Lawton & Brody, and by Ro were adopted to measure SE, IADL, and QL, respectively. The data were analyzed using t-test, ANOVA, and Pearson correlation coefficients. The results were as follows : 1. The noninstitutionalized elderly had higher scores in such measures of physical fitness as body weight, skinfold thickness, flexibility and coordination as compared to the institutionalized elderly. 2. On the following measures of physical fitness, men showed higher levels than women ; in height when standing, height when sitting, body weight, and muscle strength. Women had more trunk flexibility than men. 3. Muscle strength was positively correlated with height when standing, height when sitting, and body weight. The following measures of physical fitness, muscle strength, flexibility and coordi nation, were negatively correlated with "up and go”. 4. The noninstitutionalized elderly had higher scores in SE(t=2.28, p<0.05), IADL(t=2.24, p<0.05), and QL(t=2.41, p<0.05) as compared to the institutionalized elderly. 5. SE was positively correlated with both IADL(r=0.41, p<0.001) and QL(r=0.54, p<0.001), and the latter two variables were a positively correlated (r=0.30, p<0.001). 6. SE was positively correlated with the physical fitness measures of height when standing, body weight, strength of leg muscles, strength of back muscles, grip strength, and level of touching the floor, but negatively correlated with "up and go”. 7. Positive correlations were revealed between IADL and the physical fitness measures of height, strength of leg muscles, level of trunk muscle extension, level of touching the floor, and coordination. The IADL was negatively correlated with “up and go”. 8. QL was positively correlated with body weight (r=0.28, p<0.01) and skinfold thickness (r=0.26, p<0.05). 9. Age was negatively correlated with the physical fitness measures of height when standing, height when sitting, “up and go”, strength of leg muscles, strength of back muscles, grip strength, level of trunk muscle extension, and coordination. 10. Age was also negatively correlated with SE (r=-0.24, p<0.05) and IADL(r=-0.22, p<0.05). The above results suggest that caring elderly in their own homes were more effective and that nursing interventions to enhance physical fitness, SE, IADL, and QL especially for the institutionalized elderly are stressed.
