Purpose: The purpose of this study was to examine the impact of gluteus medius (GM) strengthening training using the pressure biofeedback unit for lower extremity muscle function and balance ability in stroke patients. Methods: Twenty-seven stroke patients (14 men, 13 women) volunteered to participate in this study. They were randomly assigned to 3 groups: pressure biofeedback unit GM training, general GM training, and control group. Experimental group 1 performed GM strengthening training using PBU in the sidelying position. Experimental group 2 performed GM strengthening training without PBU in the sidelying position. The training program lasted 4 weeks (20-minute sessions, three times a week). Muscle function was assessed by measuring muscle strength and endurance, and Berg balance scale (BBS), Lateral Reach Test (LRT), and limited of stability (LOS) velocity were measured for evaluation of balance ability. Results: Enhancement of muscle strength and endurance was significantly higher in experimental group 1 than in the other two groups (p<0.05). In comparison of the balance function, experimental group 1 showed a significantly enhanced ability to balance (p<0.05). After the intervention, experimental group 1 showed a significant reduction of LOS velocity in the anterior direction and affected direction (p<0.05). There was no significant difference than the other two groups but a large reduction was observed. Conclusion: These findings suggest that selective gluteus medius strengthening training using the pressure biofeedback unit is effective for lower extremity muscle function and balance ability in stroke patients.

Objective: The purpose of this study was to examine the effect of the core muscle strength enhancement of the elderly on 8 weeks training using the core exercise equipment for the elderly on the ability to control the whole-body center of mass in posture stabilization. Method: 16 females (10 exercise group, 6 control group) participated in this study. Exercise group took part in the core strength training program for 8 weeks with total of 16 repetitions (2 repetitions per week) using a training device. External perturbation during standing as pulling force applied at the pelvic level in the anterior direction was provided to the subject. In a UCM model, the controller selects within the space of elemental variables a subspace (a manifold, UCM) corresponding to a value of a performance variable that needs to be stabilized. In the present study, we were interested in how movements of the individual segment center of mass (elemental variables) affect the whole-body center of mass (the performance variable) during balance control. Results: At the variance of task-irrelevant space, there was significant $test^*$ group interactions ($F_{1,16}=7.482$, p<.05). However, there were no significant main effect of the test ($F_{1,16}=.899$, p>.05) and group ($F_{1,16}=1.039$, p>.05). At the variance of task-relevant space, there was significant $test^*$ group interactions ($F_{1,16}=7.382$, p<.05). However, there were no significant main effect of the test ($F_{1,16}=.754$, p>.05) and group ($F_{1,16}=1.106$, p>.05). Conclusion: The results of this study showed that the 8 weeks training through the core training equipment for the elderly showed a significant decrease in the $Vcm_{TIR}$ and $Vcm_{TR}$. This result indicates that the core strength training affects the trunk stiffness control strategy to maintain balance in the standing position by minimizing total variability of individual segment CMs.

The pivotal emphasis of the physical training for the security agents of the security headquarters in the North Korea is to inspire them with the defense physical training-centered ideology and the war spirit. Their special martial arts is the protectee-centered offensive arts rather than the self-centered arts. It puts emphasis on training black belt-holders in diverse martial arts rather than in a certain martial art. Thus, the physical training for security agents in the South Korea should be also developed into the ways to rear them as black belt-holders in diverse martial arts rather than to foster them as high grade-holders in a certain martial art. And also, professors majoring in security and physical science have to develop jointly the measures to improve the physical and mental agility and the basic physical strength to inspire rapid handling and perseverance, to develop the physical training program to reduce mental and physical stress of security guards, to develop the standard for the examination of physical strength suitable for the body figures of Korean people and the regular evaluation with the standard and to apply traditional folk-games such as the swing and the seesaw to the physical training for security guards.

PURPOSE: To determine the effect of weight ball throw training as a preparatory exercise before golf practice for 8 weeks on back muscle strength, weight shifting of lower body, head speed of club, and driving distance of amateur golfers. METHODS: A total of 18 subjects were randomly assigned to the experimental group (n=9) and the control group (n=9), respectively. For the experimental group, Weight ball throw training was provided to the height of waist and shoulder similar to golf swing with the following schedule: 3 kg weight ball throw training from the first week to the 4th week; 5 kg weight ball throw training from the 5th week to the 8th week. Before and after 8 weeks of training, back muscle strength, weight shifting of lower body, head speed of club, and driving distance of subjects in the two groups were measured. RESULTS: The experimental group showed significant differences in rotational back extension torque, weight shifting of lower body, head speed of club, and driving distance during golf swing (p<.05). However, the control group only showed significant difference in driving distance during golf swing (p<.05). Back extension torque, weight shifting of lower body, and head speed of club showed significant differences between the two groups during golf swing (p<.05). CONCLUSION: Weight ball throw training can positively change rotational back muscle strength, weight shifting of lower body, head speed of club, and driving distance of amateur golfers. Therefore, it might be used as an effective warming up exercise for amateur golfers.

Background: Unstable surface-based core training can significantly enhance core strength, but no studies have compared the effects of balance pad- and sling-assisted exercises. Objects: To study the effects of unstable surface-based balance pad- and sling-assisted core strength exercises on muscle activity. Methods: Twenty male students aged 20-25 years participated in this study. The effects of three types of core strength exercises, performed with a sling or balance pad, on the activities of three muscles, i.e., the right musculus obliquus externus abdominis (EO), right erector spinae (ES), and right gluteus maximus (GM), were examined. Results: 1) In the glute bridge exercise, the percentage of maximum voluntary contraction of the EO, ES, and GM were significantly different between the balance pad- and sling-assisted exercises. The relative contribution of the ES and GM activities to all muscle activity were not significantly different between the two training types, whereas that for EO showed a significant difference. 2) There was no significant difference in the percentage value of maximum voluntary contraction (%MVC) among the EO, ES, and GM during the "leg-lifting with flat support" exercise, and there were no significant difference in the relative contributions between the two training types. 3) In the "side bridge leg separation exercise", the %MVC of the ES, EO, and GM were significantly different between the two training types. Conclusion: Sling training for core muscles was generally better than balance pad assist training. The majority of physiotherapy patients require core training. Our results could guide physiotherapists in the choice of targeted exercises for these patients.
