SUMMARY:

Introduction: Patellar tendinopathy is an overuse injury. It is possible
that mechanical hyperalgesia may modify intracortical pathways.
However, it is unclear whether potential neural modifications present in
individuals with patellar tendinopathy affect the rate of torque
development (RTD). Objective: to compare the rate of torque
development in amateur athletes with patellar tendinopathy and healthy
individuals. Secondarily, to compare isokinetic performance and single-
leg vertical jump with countermovement and to correlate RTD and jump.
Methods: this is a cross-sectional study composed of 60 male amateur
athletes of sports with intense demands on the knee extensor
mechanism, aged between 18 and 40 years. Thirty men with patellar
tendon pain were allocated to the tendinopathy group, and 30 without
pain to the control group. Measurements of isometric torque
development rate (RTD) (0-30 ms, 0-50 ms, 0-100 ms and 0-200 ms),
isometric peak torque, isokinetic peak torque, power and single-leg vertical jump with countermovement were analyzed. Comparisons of
RTD between groups were analyzed via Generalized Estimating
Equations, the remaining variables were analyzed by One-way ANOVA
with Bonferroni post hoc and Pearson's intraclass correlation
coefficient was calculated to quantify the association between RTD and
single-leg vertical jump with countermovement. Results: the
tendinopathy group presented lower late TDT (0-200 ms) in the involved
limb compared to the contralateral limb (p value <= 0.016) and in all time
intervals compared to the control group (p value < 0.05), in addition to
deficits in the height of the single-leg vertical jump with
countermovement, power, isokinetic and isometric peak torque.
Conclusion: Amateur athletes with PT presented deficits in the involved
limb in the rate of quadriceps torque development, lower functional
performance in the single-leg vertical jump with countermovement
compared to the contralateral limb and healthy controls.
