Purpose: The multiple sclerosis disease is one of the most common progressive neurological diseases in young adults. According to this matter, that risk possibility is two or three times more than healthy people. The purpose of current study is to survey the effect of balance training on posture sway in multiple sclerosis patients Study method: The current study is semi-experimental. In this regard, 20 patients with multiple sclerosis from MS Society of Iran with age range of (41/85 12/59) and scale score of disability progression (0-5) were participated in this study during 10 weeks (three times a week and Each session 1.5 hour). The posture sway in subjects were measured before and after practicing with static stabilometer machine, and also the paired sample t test with (P≤0.05) for results comparison was used. Results: The results of research showed that the effect of balance training on general fluctuations decrement (P= 0.000), anterior - posterior (P=0.02) and sway speed range (P=0.01) was meaningful but the exercises effect on medio-lateral sway (P=0.07) was meaningful. Conclusion: The achieved results from the study showed that the selected balance training was effective on general posture sway especially anterior–posterior.
The aim of this study is to examine the effect of eight-week core and balance training on single-leg sway parameters and well-directed kick of male soccer players. 24 male players of an amateur soccer club aged 14 to 15 participated in the study. The participants were randomized into an experimental group (EG, n=12) performing core and balance trainings with soccer training and a control group (CG, n=12) performing only their routine soccer training programs for 8 weeks. Biodex Balance SD (Biodex Inc., Shirley, NY) device was used to measure single-leg sway parameters and Mor–Christian general aptitude soccer test was used to evaluate well-directed kick. EG athletes showed statistically better results in well-direct kick and dominant-leg-sway parameters than CG athletes (p < 0.05) while there was not seen any changes on non-dominant leg sway parameters (p > 0.05). When classical soccer practice supported by core and unstable surface exercises, possible developments in balance affects dominant and non-dominant legs of athletes to achieve in soccer the necessary skills more easily so it can be concluded that regular soccer training with core and balance exercises would be particularly effective in improving balance parameters and soccer skills.

The purpose of this study was to investigate of acute effects of anaerobic exercise at different intensities on dynamic balance performance. Twenty sedentary men who were 23.70 ± 1.45 years old, were voluntarily participated in the study. Single-blind, randomized controlled crossover design was used as experimental design. For determining dynamic balance, dynamic balance test on isokinetic balance device with dominant-single-leg test procedure was used. To create anaerobic exercise effect, Wingate anaerobic power test was used with different loads. Dynamic balance performance was measured one time before anaerobic exercise trials. During the following four days, anaerobic exercise trials with different intensities were applied in order to create anaerobic acute effect. Dynamic balance test procedure immediately applied after all anaerobic trials. For analyzing obtained data, repeated measures analysis of variance and LSD correction tests were applied. In terms of other trials, 10.0% and 7.5% anaerobic exercise trials showed significant decrement in overall and anterior-posterior balance points (p < 0.05). In terms of other trials, 10.0%, 7.5%, and 5.0% anaerobic exercise trials showed significant decrement in medial-lateral balance point (p < 0.05). Besides, balance points increased in 10.0% trial, while the balance points gradually decreased to 7.5% trial from control. In summary, it could be said that dynamic balance positively influenced from anaerobic exercise when it low intensity, and negatively influenced from anaerobic exercise when it high intensity.
