تأثیر خستگی موضعی بر پارامترهای منتخب کینماتیک راه‌رفتن مردان دارای زانوی پرانتزی

Background: Since fatigue is known as one of the limitations in individuals with genu varum which could result in functional insufficiency, the purpose of this semi- experimental study was investigation of the effects of local fatigue on selective parameters of kinematic gait in active male individuals with genu varum as well as the normal ones. Methods: The selected subjects were 30 active male students (15 with genu varum and 15 normal ones) 20 to 25 years old according to the inclusion criteria. Kinematic data were collected using a digital system. Moreover, local fatigue quadriceps muscle has been measured by Isokinetic Dynamometer System. Analysis of univariance was used to test the difference in genu varum group and normal group. Results: Results demonstrate significant difference in gait kinematic parameters such as stride, speed and knee angle in stroke phase in genu varum group in comparison to the normal group. Conclusion: Principle of specificity in athletic training should be applied as an aspect of training regimen a given stressors on the body parts. There will be a specific adaptation to imposed demands.
