The purpose of this study was to examine the effects of an aquarobics exercise program on the physical fitness and blood lipids in elderly women. The subjects of the study were twenty-six elderly women enrolled in an Aquarobics exercise program consisting of 60 minutes per session, 3 times a week during the period of 12 weeks. The effects of the program were assessed using the instruments to measure physical fitness and blood lipids before and after the aquarobics exercise program. Data was collected between September and December in 2006, and analyzed by frequency, paired with a t-test, using a SPSS. The results were statistically significant in muscle strength, muscle endurance, flexibility, and cardiopulmonary endurance, but no significant differences were found in agility, total cholesterol, triglycerides and high density lipoprotein cholesterol. Aquarobics exercise can be an effective nursing intervention to improve muscle strength, muscle endurance, flexibility and cardiopulmonary endurance in elderly women.

In this study, Theta Gamma Coupling (TGC) analysis was carried out after performing simple and repeated upper limb exercise and comparative experiment to observe changes in the motor cortex of the brain through TGC and to see if mobile rehabilitation therapy is actually effective. As a result, exercise using mobile devices showed higher TGC values in motor cortex as compared with simple repeat upper limb exercise. In addition, paired t-test using SPSS showed statistically significant difference between exercise using mobile devices and simple repeat exercise at P3(t=3.390, df(degree of freedom)=12, p value=0.005). Exercise using mobile devices is effective for rehabilitation because it increases the Theta-Gamma Coupling and activates the motor cortex. Also, since the mobile game contents required the subject to detailed athletic ability adjustment with immersion in the task, it may be thought that brain activation is stronger than simple rehabilitation.

PURPOSE: This study analyzed the effectiveness of respiratory exercise in stroke patients conducted in Korea over the past 10 years (2012-2023). METHODS: Using the RISS, KCI, KISS, and NDSL databases, previous studies on stroke and respiratory exercise were searched, and relevant articles were collected following the PRISMA guidelines. Twelve articles were selected, and the quality of the studies was evaluated using the PEDro scale. RESULTS: Twelve studies were selected, and the qualitative evaluation of these studies showed that five articles received a score of six out of 10, while five articles received a score of five. The remaining two articles received scores of four and three, respectively. The intervention duration for respiratory exercise ranged from 20 to 30 minutes per session, with a frequency of three to five sessions per week, conducted over a period of three to eight weeks. These results indicated that respiratory exercise effectively improved the respiratory function, physical function, and respiratory muscle activation in stroke patients. CONCLUSION: Respiratory exercise was reported to have a positive affect the respiratory function, physical activity, and respiratory muscle activation in stroke patients.

PURPOSE: The purpose of this study was to investigate the changes in the flexibility and elasticity of the muscles when the hamstrings were stretched in one direction and when they were stretched in three directions. METHODS: In this study the subjects were divided into two groups, namely the 'one-direction stretching exercise of the hamstring muscle in the neutral position' group (female: 14 people, male: 14 people) and the 'three-way stretching exercise' group (female: 12 people, male: 14 people) considering the positions of the three hamstring muscles. The elasticity and flexibility of the hamstring muscles were measured before and after the self-extension exercise, and the average value of two measurements was noted. To evaluate the flexibility of the hamstring muscle, a 'sit and reach' test was performed, and muscle elasticity was measured using the MyotonPRO® device. RESULTS: After the stretching exercise, flexibility increased in both groups. In terms of muscle elasticity, the body dynamic strength and resonance frequency of the stretching one-direction stretching group decreased after the stretching exercise. CONCLUSION: To alter the muscle characteristics and increase the flexibility when performing a stretching exercise, selecting and stretching only one muscle with the lowest range of motion yields effective results. The ideal technique to be employed appears to be to stretch the entire hamstring muscle in one direction from the neutral position.

The objective of this study was to develop an FES exercise protocol that can enhance muscle force and fatigue resistance and to evaluate the resulting effects. We investigated contraction and fatigue properties of vasti of 10 normal subjects and 4 paraplegics by applying different types of electrical stimulation. Based on the results, we have been training quadriceps of a male paraplegic patient. The results suggested that the exercise be applied 7 days a week, and confirmed that low frequency and intermittent stimulation delays fatigue. After the two-year FES exercise, the patient's knee extensor torque increased by about ten folds and the fatigue index decreased to half of the preFES value.
