The effects of obesity on the balance and gait parameters like step width and foot angle (degree of toe out) in young adults were studied. 60 subjects of both the genders were taken. 30 were taken as a control group (non-obese, BMI < 25) and 30 were taken as experimental group (obese, BMI 30 >). Functional Reach Test (FRT) was used for Balance Testing and the Footprint method was used for Gait parameters measurements. The value of functional reach test in females was 11.90 +/- 0.12 inches in control group and 7.01 +/- 1.80 inches in experimental group (t = 5.31, P < 0.001) and in males, it was 16.45 +/- 0.72 inches in control and 11.66 +/- 0.53 inches in experimental group (t = 6.47, P < 0.001). The degree of toe out in females was 6.66 +/- 0.08 degrees for control and 8.13 +/- 0.21 degrees for experimental group (t = 4.08, P < 0.01) and in males, it was 6.59 +/- 0.04 for control and 9.79 +/- 0.51 for experimental group (t = 6.53, P < 0.001). The step width was found to be 4.41 +/- 0.15 inches (control group) and 6.27 +/- 0.35 inches (experimental) in males (t = 4.53, P < 0.01) and it was 3.95 +/- 0.03 inches (control) and 3.42 +/- 1.05 inches (experimental) in females (t = 0.77, P > 0.05). We concluded that obesity has a negative impact on balance of an individual. The degree of toe out was more in obese group as compared to normal BMI group in both genders. The Step Width measurement was more in males of obese group than that in males of normal BMI group but it showed statistically insignificant when compared in females of both groups.
研究了肥胖对年轻人平衡和步态参数（如步宽和足角（外展角度））的影响。选取了60名受试者，男女各半。30名作为对照组（非肥胖，BMI<25），30名作为实验组（肥胖，BMI>30）。采用功能性伸展测试（FRT）进行平衡测试，采用足迹法测量步态参数。对照组女性的功能性伸展测试值为11.90±0.12英寸，实验组为7.01±1.80英寸（t = 5.31，P<0.001）；男性对照组为16.45±0.72英寸，实验组为11.66±0.53英寸（t = 6.47，P<0.001）。对照组女性的外展角度为6.66±0.08度，实验组为8.13±0.21度（t = 4.08，P<0.01）；男性对照组为6.59±0.04度，实验组为9.79±0.51度（t = 6.53，P<0.001）。男性的步宽在对照组为4.41±0.15英寸，实验组为6.27±0.35英寸（t = 4.53，P<0.01）；女性对照组为3.95±0.03英寸，实验组为3.42±1.05英寸（t = 0.77，P>0.05）。我们得出结论，肥胖对个体平衡有负面影响。肥胖组的外展角度在男女中均高于正常BMI组。肥胖组男性的步宽测量值高于正常BMI组男性，但两组女性比较时差异无统计学意义。
