The purpose of this study was to investigate the effects of rhythm of aerobic exercise in elderly women. Thirty subjects were randomly divided into two groups: The aerobic exercise with rhythm (experimental group, n=9) and aerobic exercise without rhythm (control group, n=10). All subjects performed aerobic exercise composed of functional movements. During the exercise, control group subjects were performed the functional movement exercise only to the beat without music or rhythm and experimental group subjects were performed the functional movement exercise to the rhythm of the music. All subjects performed exercise for 50 minutes, twice a week, total of 8 weeks. The forced vital capacity (FVC), forced expiratory volume in one second (FEV1), and maximal voluntary ventilation (MVV) were measured. Functional movements were assessed using FMS (Functional Movement Screen). Quality of life (QOL) were assessed using SF-36. Evaluation was performed before and after 8 weeks of exercise and one month later for follow-up. The FVV, FVC1, MVV, FMS, and SF-36 have shown a significant difference in time as a result of the twoway repeated-measures analysis. The post mean change of FVC1, MVV, FMS, and SF-36 were significantly different between groups. In this study, aerobic exercise, which is composed of rhythmic functional movement, helped improve functional movement and QOL for the elderly women. When the experimental group and the control group were compared, the improvement of the experimental group with music and rhythm was more positive than the exercise using the same functional movement.

Objective: The purpose of this study was to investigate the effects rhythmic and non-rhythmic aerobic exercises on depression and balance of healthy elderly people. Design: Randomized controled trial. Methods: Nineteen older subjects were randomly divided into 2 groups for rhythmic and non-rhythmic aerobic exercises. Both aerobic exercises consisted of functional movements such as turning in opposite directions, and running in place, the exercise consisted of movements that could activate balance. The rhythmic training group initially used music with 8 beats, and then later progressed to 16 beats. Additionally, we adjusted the pace of the music using songs from 125 beats per minute (bpm) to 160 bpm. Both groups were exercised for 50 minutes a day, twice a week, for a total of 8 weeks. We measured the condition of the patients before the intervention, and after 8 weeks of intervention. The Beck depression inventory (BDI) was used to measure the degree of depression. The Berg balance scale (BBS) was used to measure static and dynamic balance ability. We measured the subject's subjective balance confidence using the fall efficacy scale (FES). Results: Both groups showed significant improvement in BDI, BBS, and FES (p<0.05). The rhythmic aerobic exercise group showed a significant improvement only in the BBS change values compared to the non-rhythmic group (p<0.05). Conclusions: According to this study, both rhythmic and non-rhythmic aerobic exercises resulted in significant improvement in the degree of depression and balance ability of the elderly. The rhythmic aerobic exercise was more effective for dynamic balance ability.

For patients suffering from spinal cord injuries, both of the possibility of having complications with the respiratory system and the related fatal rate are still high, while pneumonia is the most important cause of these fatalities. This research was carried out to find out what effects does a breathing exercise have on the respiratory functions and the improvement in the quality of life. The study was carried out for male patients suffering cervical spinal cord injuries for the purpose of inspiratory muscle strengthening. The objects of the study were 17 non-smoking-at-present male patients with C4 to C6 cervical spinal cord injuries. They had practiced inspiratory muscle strengthening training for three times a week for six weeks. The quality of life and the dyspnea (breathing difficulty) were self-measured before and after the training. As a result, the change in respiratory function was only significantly reduced (p<0.01) within the chronic group. In terms of the changes in the quality of life, the sub-acute group has only seen a significant improvement (p<0.05) for the VT(vitality), while the chronic group has seen significant improvements(p<0.05, p<0.01) in: GH(general health); BP(back pain); and VT(vitality). In this research, the inspiratory muscle strengthening has reduced the dyspnea (breathing difficulties) and improved the quality of life.

Background: The aim of this study was to examine the concurrent validity and inter-and intra-rater reliabilities of smart device based application, against force platform-based portable device Wii balance board (WBB) measurements for the flight time and jump height during the vertical jump. Material and methods: Thirty participants (23.8 ±3.41 years) completed three vertical jumps, which were evaluated using WBB and application for smart device. To assess the concurrent validity, jump height and flight times were obtained from each device. Inter-and intra-rater reliabilities were determined by replicating data analysis of smart device based application recordings. Results: Flight time and jump height collected from smart device based application showed excellent agreement level with WBB (flight time and jump height: ICC [2,1]=0.972). However mean flight time and jump height from the smart device based application was significantly higher than WBB (mean difference: 0.006 sec, 0.745 cm, p < 0.05). Intra-rater sessions showed good level of agreement (flight time: ICC [2,1] = 0.967, jump height: ICC [2,1] = 0.974), and inter-rater session showed almost perfect reliability (flight time: ICC [2,1] = 0.985, jump height: ICC [2,1] = 0.987). Conclusions: Smart device-based applications could be used to replace pressure-based portable devices for clinical evaluations in post-injury rehabilitation as well as evaluating sports performance.
