Purpose: This study was to investigate the effects of isometric exercise on muscle activity and body balance ability in asymmetrical walkers. Research design, data, and methodology: Twenty gait asymmetry people were divided to unilateral exercise group (UG, n=10) and bilateral exercise group (BG, n=10). UG were performed unilateral exercise for 60 minutes, three times a week, and 16 weeks, and BG were performed one side and then the other side alternately for 60 minutes, three times a week, and 16 weeks. Muscle activity and body balance ability were measured before, after 4 and 16 weeks isometric exercise. Moreover, SI (symmetry index; SI) was calculated from the measured value of SL (step length). Statistical analyses were conducted using one-way ANOVA and two-way ANOVA with repeated measures, a paired t-test, and multiple comparisons according to Scheffe. Results: In the muscle activity, ST decreased significantly in short step length(S-SL) and BG of LS compared to before isometric exercise(p<.05), and GCM decreased significantly in BG of S-SL(p<.05). As for body balance ability, the mSEBT-A difference between L-SL and S-SL was decreased significantly in UG(p<.05). And the respective total scores of L-SL and S-SL, mSEBT-PM and mSEBT-PL were increased significantly in BG(p<.05). Conclusions: As a result, in this study above, it was confirmed that isometric exercise improved muscle activity and body balance ability in asymmetrical walkers.

The purpose of this study is to investigate the difference of muscle activity according to application of a foam roller during pilates. The 8 male subjects were selected and quadruped position, bridge, and core control movement of pilates were randomly assigned to 9 movements on a static mat motion, static foam-roller motion, and dynamic foam-roller actions. This program was conducted once at intervals of 1 week. The muscle activity of erector spinae, rectus abdominis, external oblique, gluteus medius, rectus femoris, and biceps femoris were measured and the collected data was analyzed by one-way ANOVA. First, in the quadruped, the rectus abdominis and external oblique, rectus femoris of the dynamic foam-roller actions showed higher muscle activity than the static mat motion and the static foam-roller motion(p <.001), gluteus medius muscle activity was also significantly higher (p <.05). biceps femoris were significantly higher in static foam-roller motions than in static mat-motion and dynamic foam-roller actions(p <.05). Second, biceps femoris muscle activity was highest in dynamic foam-roller actions than static mat-motion and static foam-roller motions during bridge(p <.001). Third, in the sitting core control, the rectus abdominis and gluteus medius of the dynamic foam-roller actions showed higher muscle activity than the static mat motion and the static foam-roller motion(p <.001). and activity of erector spinae muscle was also significantly higher (p <.01). external oblique were significantly higher in static mat-motion than in static foam-roller motions and dynamic foam-roller actions(p <.05). Considering the muscle activity during pilates exercise, it would be more effective to apply the method and difficulty.

The purpose of the present study was to investigate the effect of climbing resistance training on GLUT-4 protein and LDH isozyme activities of the soleus and gastrocnemius muscles in rats. Each experimental group was randomly divided into a control group (n=6) and a resistance exercise (n=6) group. Sprague-Dawley rats were made to climb a 180 cm tower for 12 wk. Weight changes in the resistance exercise group were significantly higher than in the control group (p<0.05). GLUT-4 protein expression of the soleus and gastrocnemius muscles was significantly higher (p<0.05) in the resistance exercise group than in the control group. There was no difference in soleus tissue LDHA4 isozyme activity between the groups. In the case of other LDH isozyme, when compared with the control group, the resistance exercise group showed a significantly higher activity (p<0.05). LDHA4 activity of gastrocnemius muscle tissue was not different between the groups. However, the activity of the resistance exercise group of all the other LDH isozymes was significantly higher than that of the control group (p<0.05). In summary, based on the results of this study, over 12 weeks of resistance training, the total body weight of the rats was reduced and the GLUT-4 activity in the gastrocnemius and soleus muscles was increased. In addition, except for LDH A4 all of the other LDH isozymes activities were increased. These results suggest that climbing resistance training affects the balance of body composition, increases LDH B-type isoenzymes and glucose metabolism capacity, and improves mitochondrial function.
