The assessment of the plantar-flexors muscle strength in older adults (OA) is of the utmost importance since they are strongly associated with the performance of fundamental tasks of daily life. The objective was to strengthen the validity of the Calf-Raise-Senior (CRS) test by assessing the biomechanical movement pattern of calf muscles in OA with different levels of functional fitness (FF) and physical activity (PA). Twenty-six OA were assessed with CRS, a FF battery, accelerometry, strength tests, kinematics and electromyography (EMG)...

BACKGROUND AND PURPOSE: Major League Soccer (MLS) has aggressively expanded from 10 teams to 23 teams. With the addition of more teams, the league will have to dictate a schedule that maximizes the league's popularity, while also maintaining the health of the players. A longer season and congested game schedule could increase the risk of injury for players. The purpose of this commentary is to make recommendations for the prevention of injuries among MLS players with respect to proposed league expansion...
