Purpose: This study aimed to assess the effect of rowing ergometer training on the aerobic capacity and strength of male high school students over a 12-week period. Methods: Fourteen high school students volunteered to participate in the study. The subjects were divided into two groups: seven subjects in the experimental group and seven in the control group. The subjects in the experimental group performed rowing ergometer training for 75 min per session at three days a week for 12 weeks. The exercise intensity set the maximum heart rate (HRmax) from 40% to 80%. Aerobic capacity was measured by ventilation, cardiac output, and oxygen intake per body weight. Strength was measured by grip strength and back strength before and after training. Results: A significantly increased ventilation (p=0.01), cardiac output (p=0.01), and oxygen intake per body weight (p=0.00) were found in the experimental group. A significantly increased grip strength in the right and left hands (p=0.00, 0.00) and back strength (p=0.04) were observed in the experimental group. Conclusion: Rowing ergometer training can be an effective combined exercise for aerobic capacity and strength of high school students.

Purpose: The purpose of the study was to investigate the effect of a training program using virtual reality on the balance and lower muscular strength of Parkinson's disease patients. Methods: The study included 22 patients with Parkinson's disease who were arbitrarily classified into 2 groups: 11 patients in the experimental group and 11 patients in the control group. Balance was measured with the Berg balance scale (BBS), the functional reach test (FRT), one-leg stance test (OLST), and the timed up and go test (TUG); whereas, lower muscular strength was measured with the sit-to-stand test (STS). Ping-Pong, bowling, and tennis were selected for virtual reality training for the experimental group, and were performed for 30 minutes 3 times a week for 8 weeks. The control group did not undergo any of the virtual reality training programs. Results: A significant difference was observed in the BBS, FRT, OLST, TUG, and STS results within the experimental group that underwent the virtual reality training program. On the other hand, no significant difference was observed in the BBS, FRT, OLST, TUG, and STS values within the control groups. Conclusion: In conclusion, the virtual reality training program positively affects the balance and lower muscular strength in Parkinson's disease patients. This result indicates the possibility of application of the virtual reality training program to the management for Parkinson's disease patients, and highlights the need for the development and application of more efficient virtual reality training programs in the future.

Objective: In this study, we analyzed kinematic changes in the start phase of speed skating before and after physical training. Method: We introduced a new strength training program (2017) that was improved in terms of exercise type and intensity [%, one repetition maximum (1RM)] compared with the previous strength training program (2016). The new program was applied to elite speed skating athletes (four males and four females). To determine the improvement in starting technique, we recorded race images during the start phase of the 500-m race held in 2016 and 2017. The race images were collected using five high-speed cameras and kinematic characteristics of the start phase were analyzed by three-dimensional image analysis. Results: The 1RMs were improved by 11% on an average after the strength training. In 2017, records of four out of the eight athletes were shortened in terms of the initial lap time (100 m), and 500-m records were shortened in six athletes. The time to nine strokes was shortened in five athletes, and the ratio of correct kinetic chain was increased or maintained at a high level in six athletes. Conclusion: In this study, the new strength training program (2017), applied to elite speed skating athletes, showed a positive effect on starting technique and reduced the record times.

Objectives : The purpose of the research is to measure Dental Hygiene students' level of musculoskeletal pain before and after receiving scaling training which involves repetitive operations and examine effects the operations have on the students' grip and pinch strength. Methods : 15 subjects in Dental Hygiene at Y university located in Chungbuk were tested on November 2, 2011. Results : 12 students had a musculoskeletal pain before receiving scaling training. However, all the 15 students had a musculoskeletal pain after the training. Body part the largest number of the students complained of the pain on was shoulders(37.9%) followed by neck(20.8%), waist(13.9%), wrists(10.3%), then back(6.9%) before receiving the training. Then the result showed that shoulders are where the largest number of students(24.1%) felt the pain, followed by neck(17.2%), wrists and fingers(13.8%), waist(12.1%), back and lower arms(6.9%), then palms(5.2%) after the training. Visual Analogue Scale(VAS) increased to $6.35{\pm}2.09$ after receiving the training from $3.31{\pm}3.38$ and this shows statistically significant difference(p<.001). Upon inspection, average grip strength decreased to $23.23{\pm}5.79kg$ from $25.00{\pm}4.51kg$ after receiving the training and this shows statistically significant difference(p<.05). Key pinch was the strongest among the three pinch strengths followed by tripod pinch then tip pinch. Average of all the three pinch strengths showed to have statistically significant difference before and after the training(p<.05); Tip pinch from $6.53{\pm}1.36$ to $5.87{\pm}1.3$, key pinch from $13.47{\pm}2.5$ to $12.53{\pm}2.30$, and tripod pinch from $9.27{\pm}3.04$ to $8.03{\pm}2.72$. Conclusions : The result showed that scaling training has effects on Dental Hygiene students' musculoskeletal subjective symptoms and their grip and pinch strength changes after receiving the training.

PURPOSE: The aim of this study was to investigate the effect of closed and open kinetic exercises on knee extensor strength and balance in patients with early stroke. METHODS: Thirty patients with early stroke participated in the study. Participants were randomly assigned to three groups: an open kinetic chain (OKC) exercise group (n=10), a closed kinetic chain (CKC) exercise group (n=10), and a control group (n=10). All participants received conventional physical therapy for 30 minutes. In addition, the two experimental groups (OKC and CKC) participated in a 30-minute knee strengthening training program. Training for the experimental groups was carried out three times a week for four weeks. Outcomes such as knee extensor strength and balance ability (Tetrax, Functional Reaching Test, Timed Up and Go Test) were measured before and after training. RESULTS: There were significant differences in knee extensor strength and balance ability between the pre- and post-treatment of all groups (p<.05). The improvement of knee extensor strength was significantly higher in the OKC group than in the other groups (p<.05), and the improvement of dynamic balance was significantly higher in the CKC group than in the other groups (p<.05). CONCLUSION: These results showed that both open and closed kinetic chain exercises are effective in the improvement of knee extensor strength and balance ability. This study suggests that open and closed kinetic exercise training is an effective training for strength and balance in patients with early stroke.

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.

PURPOSE: The purpose of this study was to examine the effects of respiratory muscle training on respiratory function, respiratory muscle strength, and cough capacity in stroke patients. METHODS: This study used a nonequivalent control group pre-post test design. We recruited thirty-four stroke patients(16male, 18female), who were assigned to intervention (n=17), or control (n=17) groups. Both groups participated in a conventional stroke rehabilitation program, with the intervention groups also receiving respiratory muscle training 20 minutes a day, three times a week, for 4 weeks. Respiratory function (forced vital capacity) and respiratory muscle strength (maximal inspiratory pressure, maximal expiratory pressure) were assessed by spirometry. Cough capacity (peak expiratory flow) was assessed using a peak flow meter. The collected data were analyzed by independent and paired t-tests. RESULTS: The intervention group showed a significant increase in the forced vital capacity (FVC), maximal inspiratory pressure (MIP), maximal expiratory pressure (MEP) and peak expiratory flow (PEF) at the end of the program, while the control group showed no significant changes. CONCLUSION: This study showed that respiratory muscle training increased respiratory function, respiratory muscle strength, and cough capacity in stroke patients and prevented a decrease in cough capacity. These findings suggest that respiratory muscle training effect on respiratory function, respiratory muscle strength and cough capacity for rehabilitation in patients with stroke.

The effects of a hypocaloric diet with or without strength training on body fat distribution and serum lipid concentrations in obese elderly women were investigated. Twenty-six healthy women (age 66±4.6 yr; body mass index 32.3±2.9 kg/m²) were randomly assigned to 3 groups: control (C; n=8), hypocaloric diet (DO; n=9) or hypocaloric diet with strength training (DST; n=9). Subcutaneous adipose tissue (SAT), visceral adipose tissue (VAT), and inter and intra muscular adipose tissue (IMAT) were measured using magnetic resonance imaging. Serum lipid concentrations including total cholesterol (TC), high density lipoprotein cholesterol (HDLC), low density lipoprotein cholesterol (LDLC), and triglycerides (TG) were measured. No significant changes occurred in body weight and percent body fat in the C group over the 16-week period. The DO and DST groups lost similar amounts of weight and fat after 16 weeks. SAT and VAT decreased after weight loss in the DO and DST groups but not in the C group. IMAT was significantly reduced in the DO and DST groups, whereas in the C group IMAT increased. The loss in IMAT mass was similar in the DO and DST groups. TC and LDLC decreased in the DO and DST groups but not in the C group. There were no differences between the DO and DST groups in decrease in TC and LDLC. HDLC decreased in the DO group but not in the C and DST groups. TG tended to decrease in the DST group. In conclusion, body fat distribution including SAT, VAT, and IMAT and serum lipid concentratons were modulated by weight loss resulting from the hypocaloric diet with or without strength training in obese elderly women. Strength training did not enhance the improvement in body fat distribution and serum TC and LDLC concentrations by the hypocaloric diet.
