Background: Pectoralis major (PM) tendon tears are a relatively uncommon injury that typically occurs in young, active population during weightlifting or recreational sports. Musculotendinous junction and chronic PM often require reconstruction due to inadequate remnant stump inability reduce the humeral footprint. Indications: We favor operative repair of all young patients medically appropria...

AbstractObjectives Recent studies investigated the determinants of trail running performance (i.e., combining uphill (UR) and downhill sections (DR)), while possible specific physiological factors specifically determining UR vs DR performances isolating DR) remain presently unknown. This study aims to determine cardiorespiratory responses outdoor time-trial explo...

Objective-To determine the effect of stretching and jogging on the series elastic muscle stiffness of the plantar flexors and on the range of dorsiflexion at the ankle joint. Methods-24 healthy subjects participated in this study. Each subject undertook all of the following protocols, in random order: (1) stretching protocol: five 30 s static stretches with 30 s rest between stretches; (2) aero...

The effect of instrument-assisted soft tissue mobilization (ISTM) on passive properties and inflammation in human skeletal muscle has not been evaluated. Passive properties of muscle, inflammatory myokines and subjective reporting of functional ability were used to identify the effects of ISTM on the plantar flexors. 11 healthy men were measured for passive musculotendinous stiffness (MTS), pas...
