Usual modal analysis techniques are based on the Fourier transform. Due to the ∆T.∆f limitation, they perform poorly when the modal overlap μ exceeds 30%. A technique based on a high-resolution analysis algorithm and an order-detection method is presented here, with the aim of filling the gap between the lowand the high-frequency domains (30% < μ < 100%). A pseudo-impulse force is applied at po...

PURPOSE To investigate the within-session reliability of bilateral- and unilateral-stance isometric midthigh-pull (IMTP) force-time characteristics including peak force (PF), relative PF, and impulse at time bands (0-100, 0-200, 0-250, and 0-300 milliseconds) and to compare isometric force-time characteristics between right and left and dominant (D) and nondominant (ND) limbs. METHODS Profess...

The maximal rate of rise in muscle force [rate of force development (RFD)] has important functional consequences as it determines the force that can be generated in the early phase of muscle contraction (0-200 ms). The present study examined the effect of resistance training on contractile RFD and efferent motor outflow ("neural drive") during maximal muscle contraction. Contractile RFD (slope ...

BACKGROUND Aquatic plyometric programs are becoming increasingly popular because they provide a less stressful alternative to land-based programs. Buoyancy reduces the impact forces experienced in water. PURPOSE To quantify the landing kinetics during a range of typical lower limb plyometric exercises performed on land and in water. STUDY DESIGN Crossover design. METHODS Eighteen male par...
