Isokinetic muscle performance and salivary immune-endocrine responses in handball players by Fourier transform infrared spectroscopy

[摘要] Research on professional sports has examined parameters to establish muscle function,1,2 as well as the association between physical fitness level and overtraining biomarkers, such as cortisol, salivary cortisol and immunoglobulin A (SIgA), and α-amylase, among others.3,4 In collective sports, evaluation of the knee joint is very important due to the demand imposed on it during training and competition. Isokinetic testing enables precise assessment of athletes’ muscle strength; therefore, this method allows evaluation of quadriceps and hamstring muscle strength, to determine the magnitude of generated torque, as well as the hamstring to quadriceps (H/Q) strength ratio. This evaluation is also widely used in injury prevention programmers.1,5,6
