Blazevich et al in their study of reliability and validity of two isometric squat (IS) tests, reported that IS with an isometric rack showed significant and high correlation (r = 0.77) with 1RM squat. However, when Demura, S studied the relationship between 1RM and isometric measurement of squat(IS), their study showed that some component (wide stance and parallel depth) of the squat correlated well with 1 RM whereas others did not. Simple linear regression analysis in their study revealed a relationship of Y = 0.992X + 30.3 (Y: 1RM, X: IS). This suggested that the IS using a back dynamometer may become an effective index for predicting 1RM squat. However, since the standard error of an estimate provided by the regression equation was quite large, (11.19 kg) therefore, it could not estimate 1RM in non-athletes; this study concluded that estimating a 1RM by Isometric squat using a back dynamometer maybe difficult. Though some studies have been conducted to estimate 1RM from isometric strength measurement, there is a dearth in literature to prove the same. Therefore the investigators aim to find out if isometric strength can be compared with 1RM in female subjects without weight training experience. Hence the purpose of this study is to find if there can be comparisons between 1RM (Brzycki's prediction equation) measurement and isometric MVC using a digital hand-held dynamometer in healthy females.
