Abstract: Strength training is commonly employed to enhance underlying strength and power traits in elite athletes. Strength assessments are then used to assess the progression of these traits especially isometric strength tests which has gained traction in recent years for instance, the isometric squat as a preferred lower limb test. However, the relationship between isometric squats and dynamic squats in predicting 1-repetition maximum (1RM) is unclear. To investigate the accuracy of predicting the 1RM squat using peak force obtained from Isometric Squat (IsoSqt). A repeated measures design was utilized, where 29 participants were required to test their dynamic 1RM squat followed by two IsoSquat Peak force testing sessions. In order to participate, participants needed a minimum of one year of resistance training experience, proficiency in executing a 1RM squat, no sustained injuries or illnesses in the six months leading up to the study, and the ability to squat a weight equivalent to 1.5 times their body weight. The peak force was measured using dual force plates at knee angles of 60, 90 and 120 degrees. Participants were directed to place their feet in the same position as while performing their 1RM squat. There was a significant and very large correlation between Squat 1RM and peak force at all knee angles. There was no significant difference between predicted and obtained values for the 1RM squat. The standard of error obtained from the equation was 0.6 ± 10.4%. Isometric Squat Peak Force is a highly reliable test for assessing squat 1RM.
