Purpose: This study was conducted to evaluate the effects of neck and trunk stabilization exercise on static and dynamic balance in older adults. Methods: A total of 30 older adults participated in this study. Participants were randomly assigned to the neck and trunk stabilization exercise group (NTSG) (n=15) or the trunk stabilization exercise group (TSG) (n=15). The NTSG performed a trunk stabilization exercise added to a neck stabilization exercise that included biofeedback. Both groups received training for 30 minutes per day three times per week for eight weeks. The anterior, posterior limit of stability and sway length was used to measure static balance ability, while the timed up and go (TUG) test was used to measure dynamic balance ability. Results: Participants showed significant differences in sway length, anterior limit of stability, posterior limit of stability, and the results of the TUG test between their pre- and post mediation evaluations (p<0.05). The NTSG showed a more significant increase than the TSG (p<0.05). Conclusion: According to the results of this study, both exercises effectively improved static and dynamic balance ability. However, the neck and trunk stabilization exercise is more efficient for increasing the balance ability of older adults.

Purpose : The purpose of this study was to investigate the effect of stair exercise and Kegel combined exercise on the maximum voluntary ventilation (MVV) and limits of stability (LOS). Methods : 23 female students participated in this experiment. MVV was measured with a spirometer. The LOS was measured with a Biorescue. Subjects were randomly assigned to two groups. 12 subjects were assigned to the experimental group and 11 subjects were assigned to the control group. The experimental group performed 5 minutes of stair exercise and 5 minutes of Kegel exercise. The control group performed 10 minutes of stair exercise. After 5 minutes of exercise, 1 minute of rest was provided. Both groups exercised for 5 minutes according to the metronome beat 130 during the stair exercise. After 5 minutes of rest after exercise, MVV and LOS were measured again in the same way. The measurement sequence was also randomly alternated. Results : Significant differences were found within and between groups in the experimental group in MVV (p<.05). In LOS, significant differences were confirmed in left, right, forward, backward, and total LOS in the experimental group (p<.05). In the control group, there were significant differences in left, forward, and total LOS (p<.05). However, there was no significant difference between groups (p>.05). Conclusion : Based on the results of this study, it was confirmed that the stairs and Kegel combined exercise had a positive effect on MVV and LOS. However, in the short term, it was found that the stair and Kegel combined exercise was insufficient in time and the threshold of exercise to show the difference between groups in LOS. Therefore, additional research should be conducted by modifying the limitations of this study.

Purpose: Unilateral strength training effects on contralateral sides have been demonstrated in previous studies for lower extremity exercise, upper extremity exercise, and unilateral surface electrical stimulation. This study was performed to investigate the effects of unilateral ankle training on muscle strength and the balance of contralateral lower extremity in healthy adults. Methods: Thirty healthy subjects were randomized equally to a training or a control group. Those in the training group received unilateral ankle isokinetic strengthening training of the dominant leg (right side) for 4 weeks. Contralateral single-limb balance, including Anterio-Posterior Stability Index (APSI), Medio-Lateral Stability Index (MLSI) and Overall Stability Index (OSI), was assessed before and after intervention. Results: Comparison of pre- and post-test data revealed significant improvements in ipsi- and contralateral ankle strengths, and significant improvement in contralateral single limb balance. Conclusion: These results have practical implications because they demonstrate that unilateral ankle isokinetic exercise improves ankle muscle strength and balance ability of contralateral lower extremity.

The stability of protein tissues and protein fibers in the human muscle is investigated in the presented paper. The protein fibers are modeled via tube structures embedded in others proteins fibers like the elastic substrate. Physical sport and physical exercise play an important role in the stability of synthesis and strength of the protein tissues. In physical exercise, the temperature of the body increases, and this temperature change impacts the stability of the protein tissues, which is the aim of the current study. The mathematical simulation of the protein tissues is done based on the mechanical sciences, and the protein fibers are modeled via wire structures according to the high-order theory beams. The thermal stress due to the conditions of the sport is applied to the nanoscale protein fibers, then the stability regarding the frequency analysis is investigated. Finally, the impact of temperature change, physical exercise, and small-scale parameters on the stability of the protein tissues are examined in detail.

Background: The purpose of this study was to evaluate the pain, static balance, and dynamic balance abilities of women with chronic low back pain by performing thoracic and hip joint mobility exercises and lumbar stability exercises. Methods: The subjects of this study were 20 adult women with low back pain who lived in C city for more than 12 weeks. The experimental group performed the thoracic and hip mobility exercises with lumbar stability exercises and the control group performed the lumbar stability exercise with general exercise program. Both groups participated in the exercise program three times a week for six weeks, from December 20, 2022 to March 7, 2023. The balance ability were measured using BT4, and pain was measured using visual analog scale (VAS). The collected data were analyzed by independent sample t-test and paired t-test using SPSS version 23.0 program. Results: After 6 weeks of intervention, there was a significant change in VAS between the experimental group and the control group, and there was no difference between the two groups (p>.05). In the case of balance ability, there was a no significant increase in the experimental group (p>.05). Conclusion: Thoracic and hip joint mobility exercises and lumbar stability exercises for adult female patients with chronic low back pain may be partially effective in static balance and dynamic balance.

This study selected 10 university football male players and repeatedly treated them as sports massage group, exercise resumption group, and stability resumption. After maximum exercise, when sport massage, exercise resumption, and stability resumption were applied during recovery, blood lactic acid concentration and $LDH_5$ isozyme concentration were examined. Finally this study obtains the following conclusion 1. There was a significant difference in both lactic acid concentration and time between groups. Besides, the cross-action on group and time was significant. 2. There was a significant difference in both $LDH_5$ concentration and time between groups. Besides, the cross-action on group and time was significant. Based on the above findings, this study suggests that sport massage resumption and exercise resumption remove blood lactic acid more quickly than stability resumption to promote recovery. That means that sport massage and exercise resumption anre very effective for lowering the level of fatigue. Thus sport massage or exercise resumption treatment is considered to have a very positive effect on player's quick recovery and it should be used aggressively in a field.
