Muscular strength in the elderly is important factors deciding on functional state in daily lives, and functional state shows a health condition. Resistance training to prevent loss of muscle mass and muscle fiber atrophy due to aging can increase muscle mass and strength. Recently, resistance training to improve muscular strength and endurance has been actively researched. Resistance training increases activities of daily living and ability of the elderly, which makes healthy senescent. ADL/IADL is suitable for measuring health condition of the elderly. In this study, target muscles of resistance training were chosen through a correlation analysis between ADLs and elementary motion, and we presented a procedure to select target muscles and exercise equipments. This procedure consist of a survey method that were described detailed motion of ADL/IADL. So we should be to extract resistance training machine to improve functions of regarding fundamental motion. Result of study may improve daily life activities of the elderly through objectives and scientific approaches. Furthermore, it will be helpful to studies about various fields of the elderly.

PURPOSE: This study examined the difference in muscle activity of the trunk and legs during flat walking with or without an abdominal drawing-in maneuver. METHODS: This study was conducted on 15 healthy males and eight females who were attending D University in Busan. This experiment was conducted after 15 minutes of abdominal drawing-in training using a pressure biofeedback unit before the experiment, and the difference in the muscle activity of the trunk and legs during flat walking with or without an abdominal drawing-in technique was investigated. Surface electromyography was used, and the electrode attachment site was the right sternocleidomastoid muscle, splenius capitis muscle, rectus abdominis muscle, external abdominal oblique muscle, transverse abdominis muscle, erector spinae muscle, vastus medialis muscle, and vastus lateralis muscle (TM DTS, Noraxon, USA). The data were analyzed statistically using a paired t-test on SPSS version 18.0 (IBM). RESULTS: The muscle activity of the rectus abdominis muscle, external abdominal oblique muscle, transverse abdominis muscle, vastus medialis muscle were increased significantly and maintained more than walking without maintaining an abdominal drawing-in maneuver (p < .05). Moreover, muscle activity of the erector spinae muscle was decreased significantly and maintained more than walking without maintaining an abdominal drawing-in maneuver (p < .05). CONCLUSION: Maintaining an abdominal drawing-in maneuver during flat walking is more effective during walking training.
Purpose: This study was done to determine whether muscle strength training programs have an impact on improving symptoms of urinary incontinence (UI) and physical function among elderly women with UI who reside in long-term care facilities. Methods: A randomized controlled trial was conducted. Participants had to be over 65 years, score over 15 score on the mini-mental state examination, and be able to walk alone or with an assistant. Seventy residents were randomly allocated to either the training group (n=35) or control group (n=35). The program consisted of 50 minutes, twice a week for 8 weeks, and included Kegel's exercise, Thera-band training and indoor walking. Main outcomes were UI symptoms, peak vaginal pressure and physical functions measured with timed up and go test (TUG), one leg standing test (OLST), activities of daily living (ADL) and grip strength. Changes in outcome measurements were calculated from baseline to 4 weeks and to 8 weeks using repeated measures ANOVA. Results: There were significant differences in peak vaginal pressure (p<.001), TUG (p<.001), OLST (p=.012) and grip strength (p<.001) in the interaction between groups and time. Conclusion: Future studies are suggested to confirm the effect of muscle strength training in long-term care facilities where elderly women with UI reside.
The purpose of this study was to identify the superior exercise on the reduction of low back pain, between the Mckenzie exercise and the williams exercise. 24 chronic low back pain patients were randomly divided into 3 groups (Mckenzie exercise group = 8, williams exercise group = 8, control group = 8). Each group examined using the Borg scale in a reduction of low back pain, the EMG amplitude in a stationary sit-up position and in a stationary 1000 back extension position. The Results are as follow. 1. After the training period, the Mckenzie exercise group and the williams exercise group revealed reduction of low back pain, but the control group does not revealed it. 2. After the training period, there were no significant differences on the reduction of low back pain between the Mckenzie exercise group and the williams exercise group. 3. After the training period, no groups decreased on the abdominal muscle EMG amplitude. 4. After the training period, all groups revealed no significant differences on the abdominal muscle EMG amplitude. 5. After the training period, all groups decreased on the low back muscle EMG amplitude. 6. After the training period, all groups revealed no significant differences on the low back muscle EMG amplitude. Overall, the study suggested that the Mckenzie exercise and the williams exercise achieve the same effect on the reduction of low back pain, and the fact seems to be influenced by other factors without muscular adaptation.

The aim of this study was to investigate the effects of respiratory muscle training (RMT) with abdominal drawing-in maneuver (ADIM) on pulmonary function. Twenty-two subjects with restrictive breathing participated in this study. All the subjects were randomly assigned to three groups (7 subjects in RMT group, 7 subjects in RMT with ADIM group, 8 subjects in control group). The first group performed the RMT by using incentive respiratory spirometer (IRS). The second group performed the RMT by using IRS and the ADIM by using a Stabilizer. The exercises were conducted over four days. The pulmonary function was evaluated using the spirometer to measure the force exploratory volume in 1 second ($FEV_1$) and forced vital capacity (FVC). Measurements were conducted on the first day and the last day. A paired-t test was used for pre-post changes and the change rates in FVC and $FEV_1$ among each group were investigated by a one-way ANOVA. The findings of the the study were as follows: 1) There were significant differences of FVC and $FEV_1$ between pre and post in the two training groups (p<.05) 2) There was no significant difference of the change ratio the FVC and $FEV_1$ between the RMT group and RMT with ADIM group. Therefore, it is concluded that respiratory muscle and ADIM training, combined with two methods of treatment would suggest positive evidence for improving pulmonary function.
Purpose: This study is to investigate the muscle activity based on real-time visual feedback training methods by rehabilitative ultrasound image in elderly and correlation between Heckmatt scale grade, muscle tone and thickness. Design: Cross-sectional study: Pilot study Methods: 6 elderly participated in the study with 2 conditions. Under the condition of rehabilitation ultrasound imaging equipment, all subjects performed voluntary maximal muscle contraction of the quadriceps 3 times using visual feedback based on Rehabilitative Ultrasound Imaging 1.0 (RUSI 1.0). Under the condition of only ultrasound images, all subjects performed voluntary maximal muscle contraction of the quadriceps 3 times using ultrasound image-based visual feedback. The muscle thickness and tone of the quadriceps were measured and the grades were classified by Heckmatt scale and all variables were comparative analyzed. Results: Heckmatt scale grade showed a negative correlation with muscle thickness at relaxation (p<0.05), and a negative correlation with the difference value obtained by subtracting muscle thickness at relaxation from muscle thickness at contraction in ultrasound image condition (p<0.05). The muscle tone during relaxation showed a negative correlation with the muscle thickness during relaxation (p<0.05). Conclusion: In the case of voluntary maximum muscle contraction of the quadriceps muscle in the elderly, it can be seen that the muscle thickness is getting larger when the RUSI 1.0-based visual feedback is provided than with only ultrasound image provided. And the lower Heckmatt scale grade is, the thicker the muscle is, and the lower the muscle tone is.
There can be little dissension that the ultimate goal of all physical therapy interventions with the elderly is to restore or maintain the highest level of function possible for the individual. Whenever physical therapists take on this challenge, they assist elders in maintaining their identities as competent adults. Advancing age is associated with profound changes in body composition, including increased fat mass, decreased fat-free mass(particularly muscle), decreased total body water and decreased bone density. Along with these changes in body compositions, and perhaps as a direct result of them, elderly people have lower energy needs, reduced strength and functional capacity and a greatly increased risk for such diseases as noninsulin-dependent diabetes mellitus and osteoporosis. Resistance training is considered a promising intervention for reversing the loss of muscle function and the deterioration of muscle structure that is associated with advanced age. This reversal is thought to result in improvements in functional abilities and health status in the elderly by increasing muscle mass, strength and power and by increasing bone mineral density. In the past couple of decades, many studies have examined the effects of Resistance training on risk factors for age-related diseases or disabilities. We have explored the positive and negative aspects of older adults' participation in resistance training programs. The benefits to older adults are reported to be increased strength, endurance, muscle capacity, and flexibility; more energy; and improved self-image and confidence. The negative aspects include some pain or stiffness and other nonspecific problems. The positive and negative aspects of resistance training are therefore very similar to those in younger populations. Scientific investigations over the past 10 years have demonstrated that resistance training can be safely and successfully implemented in older populations. Even the frail and very sick elderly can benefit and improve their quality of life. Proper design and progression of a resistance training program for older adults is vital to optimal benefits from resistance exercise. The results of data provided by this research on resistance training for health shows that there is enough existing evidence to conclude that resistance training, particularly when incorporated into a comprehensive fitness program, can offer substantial health benefits which can be obtained by persons of all ages. These benefits, including improvements in functional capacity, translate into an improved quality of life.

This study investigated the effect of whole-body vibration on muscle function and muscular reaction in the knee joint. We recruited thirty healthy subjects and divided them into a training group, who experienced whole-body vibration, and a control group, who did not. The training group performed whole-body vibration exercises for 30 min per day, 3 days a week, for 8 weeks. We measured knee joint torque to estimate muscle strength and reaction, using BIODEX System 3. Knee joint peak torque and total work performed increased significantly in the training group, and muscle acceleration time decreased. These results suggest that stimulation by whole-body vibration can improve muscle strength and reaction by improving muscle tone and increasing blood temperature and flow speed in muscular fiber. Our results also indicate that 4 weeks of exercise with whole-body vibration is required to improve the reaction response, and six weeks to improve strength.

Purpose: The purpose of this study was to classify patients with chronic back pain according to the degree of their back pain, and to compare the pain dysfunction index with the qualitative changes in abdominal muscles. Therefore, we aimed to provide a basis for the treatment intervention method for patients with back pain. Methods: Twenty patients with chronic back pain were purposive sample to a group of 10 patients with a back pain index of 60 % or more and a group with less than 60 % of back pain, and the subjects who voluntarily participated in the study After receiving the letter, I conducted the research the dysfunction of back pain was measured by the Korean version of the Oswestry Disability Index (KODI), and the ultrasonic wave (Ultrasound MyLabOne, ESAOTE, Italy) And the white area index, and the abdominal muscle movement was used as the exercise instrument POWER breathe K5 (Hab direct, UK), which strengthens the respiratory muscles through threshold-muscle traction. Result: In this study, patients with chronic back pain were subjected to breathing exercises, which led to the decrease in back pain dysfunction. The ultrasonographic analysis of abdominal muscles revealed that both the white area index and muscle image density in the skeletal muscle and in the outer muscle of the abdomen gradually decreased over time. Conclusion: It is thought that introducing back pain patients to abdominal muscle reinforcement training is effective in improving the functions of the patients' muscles, thus increasing their quality of life.

Edible insects are an interesting alternative global food resource. The purpose of this study was to investigate whether ingestion of silkworm (Bombyx mori) pupae powder with and without resistance exercise training (isometric contraction training) increased muscle mass in ICR mice. To achieve this, 28 ICR mice were grouped into control (CON), resistance exercise training (EX), silkworm pupae powder ingested control (SP), and silkworm powder ingestion with resistance exercise training (SPEX) groups. The change in body weight ratio was significantly decreased in the EX and SPEX groups compared to the CON and SP groups. Total blood protein levels were the highest in SPEX mice compared to those in other groups. The albumin concentration increased only in the EX group. Blood GOT and GPT levels were not significantly affected. Changes in Akt and Gsk-$3{\beta}$ protein expression were not significant but there was a tendency for Akt to increase and for Gsk-$3{\beta}$ to increase following the ingestion of the powder. The size of the gastrocnemius muscle increased significantly in response to resistance exercise training only. Furthermore, the ingestion of silkworm pupae powder tended to increase muscle mass without significance. These results suggested that the ingestion of silkworm pupae powder with resistance exercise training might enhance muscle mass without hepatotoxicity. However, future study may be needed to obtained detailed results and practical suggestions.
