Objective: The purpose of the present study was to compare the effects of functional and non-functional fatigue protocols on the dynamic balance of amateur basketball players. Methods: Ten amateur basketball players (mean age= 21.4±1.5 years, mean height= 177.5±7.1 cm, and mean weight= 67.4±8.5 kg) volunteered to participate in this study. Stair climbing and specific basketball movement circuit training were used to induce the non-functional and functional fatigues, respectively. Dynamic balance was measured by the postural stability test (level 2) using the Biodex balance system. Paired T-test and independent T-test were used for data analysis at a significance level of P

Purpose: Forward Walking (FW) and Backward Walking (BW) on different gradients of the treadmill is a common exercise for lower extremity rehabilitation. However, limited studies are found about the three-dimensional analysis of lower extremity and status of the knee joint during FW and BW on different gradients. Therefore, this study aimed to investigate the lower extremity joints kinematics during FW and BW on incline and decline surfaces. Methods: The current research has a quasi-experimental design. Sixteen healthy males with the mean (SD) age of 22.4(2.5) years, volunteered to participate in this study. The subjects’ FW and BW with their preferred speed on a treadmill at four gradients (-7.5%, 0%, +5% and +10%), were analyzed by using motion capture system. All data were analyzed using paired sample t test (P

Purpose: Given the high prevalence of varus malalignment of the knee and the consequences of walking on different surfaces on this malalignment, the aim of the present study was to investigate the effect of walking inclination on knee angle in the frontal plane of patients with varus malalignment. Methods: 18 male subjects with varus malalignment classified at grade 3 bowleg, within the age range of 19-24 years, volunteered to participate in this study. The parameters of knee angle in the frontal plane at the moments of heel contact, midstance and toe off when walking on -7.5, zero, +5 and +10 percent of treadmill inclination were calculated using three-dimensional motion analysis system with six optoelectronic cameras. Repeated measures of variance and non-parametric Friedman test were used for data analysis. Results: The results of the present study showed that as walking inclination increases, knee angle in the frontal plane decreases. The only significant differences were related to varus angle between +10 and zero percent inclinations at the moment of midstance (P
