An analysis of Q angle with respect to various body parameters in athletes

Abstract

The Q-angle is defined as the acute angle formed by the vectors for combined pull of the quadriceps femoris muscle and the patellar tendon. This angle helps indicating the force vector acting on the patella and patellofemoral joint and improve their individual performance by suitable workout. The present study aimed at analyze the Q angle with respect to various body parameters in athletes of Dakshina kannada district of Karnataka state. For the collection of required data 50 male and female athletes were selected respectively. Selected subjects were participated in State, National, Inter university competition since last 5 years. The Q angle was measured using a full circle universal manual goniometer made of clear plastic in the erect weight-bearing position with the subject standing. The collected data was analyzed by using mean, standard deviation z value and represented the data with the help of suitable graphs and tables.
