The purpose of this study was to compare peak force produced during the isometric midthigh pull (IMTP) and isometric squat (IsoSquat), performed at the same knee and hip angles (135 – 140°) and determine the reliability of both tests. Following a specific warmup, 22 international athletes from different sports performed 2 maximal effort tests of both the IMTP and IsoSquat. Peak force achieved during the IsoSquat was significantly greater (p = 0.01) than peak force achieved during the IMTP. Both tests were highly reliable for peak force ( %). Therefore, strength and conditioning coaches can select either test when examining lower extremity maximum strength. However, the IsoSquat produces higher peak force values and this may be a more accurate reflection of the athlete’s maximum strength.
