The main objective of this study was to determine if an acute bout of static stretching of the quadriceps muscleaffects the sense of joint position, the threshold to detect passive movement, and the sense of force. Thirty young, healthymen (age : 22.1 ± 2.7 years) were randomly divided into two groups. The Stretching Group (n=15) underwentstretching of the dominant quadriceps muscle, which comprised ten passive stretches lasting 30 seconds each, while theControl Group (n=15) remained seated for the same length of time. A repeated-measures analysis of variance was usedto establish intragroup differences over time, and an independent sample t-test was used to compare the dependentvariables between groups at each moment. None of the measurements revealed any significant change between bothgroups in each assessment moment or between moments within groups (p>0.05). This study demonstrated that staticquadriceps muscle stretching has no effect on the sense of knee joint position, threshold to detect passive movement, andforce sense, suggesting that stretching does not have appreciable effect on the spindle firing characteristics and tendonorgans activation.
