Reaction time is an indirect index of processing capabilities of the central nervous system. The present study was carried out to determine if there is any influence of body mass index on "simple reaction time in healthy young females. In this study, 60 young female participants were allotted to one of the three anthropometric groups based on their body mass index (BMI). Their reaction time to auditory as well as visual stimuli was recorded. Results were expressed as mean, standard deviation and data was analyzed using one - way ANOVA with post-hoc Tukey's HSD test. Visual as well as auditory reaction time was longer in subjects having higher and lower BMI than normal. Visual reaction time was significantly longer in subjects with lower BMI as compared to that of subjects with normal BMI (P < 0.05). Thus body mass index of an individual affects sensory motor association.
反应时间是中枢神经系统处理能力的一个间接指标。本研究旨在确定体重指数对健康年轻女性“简单反应时间”是否有任何影响。在本研究中，60名年轻女性参与者根据其体重指数（BMI）被分配到三个人体测量组之一。记录了她们对听觉和视觉刺激的反应时间。结果以平均值、标准差表示，并使用单因素方差分析和事后Tukey's HSD检验进行数据分析。BMI高于或低于正常水平的受试者的视觉和听觉反应时间更长。与BMI正常的受试者相比，BMI较低的受试者的视觉反应时间明显更长（P < 0.05）。因此，个体的体重指数会影响感觉运动关联。
