squats have previously been shown to be a predominantly knee joint or quadriceps dominant exercise, 22 and it could be argued that, due to its hip dominance and greater activation of the posterior chain, the deadlift may be a suitable alternative. 23 Therefore, the purpose of this study is to

Therefore, the purpose of this study was to examine the application of the 2-parameter, linear model to the full-body resistance training movement, the deadlift, and to estimate the critical resistance (CR: the highest sustainable resistance that can be lifted for an indefinite number of

(A vertical jump task in which jump height was computed, a squat test in which pulse rate [PR] was measured, and a deadlift task in which amount of weight in one-repetition maximum [1RM] was estimated

The purpose of this study was to determine the degree to which structural dimensions are related to strength performance in novice adolescent powerlifters. Ninety-nine high school males were measured for 17 anthropometric dimensions and maximal performance in the bench press and deadlift. Body mass and limb circumferences had the highest relationships with lifting performance. Removing the effect of body mass dramatically reduced the relationships between structural dimensions and lift performances. Multiple regression analysis indicated that size and structural dimensions could account for 68.9% and 62.4% of the known variance in the bench press and deadlift, respectively. Body size was the major determinant of weightlifting ability in adolescent male athletes, with structural dimensions playing a lesser role in determining success.

Hemodynamic and left ventricular systolic function were studied by Doppler echocardiography in 14 young and 15 older adult hypertensive patients and in 15 young and 12 older normotensive individuals. Measures were made at rest and during upright deadlift isometric exercise, at 30% of maximum voluntary contraction for 3 min. At rest, young and older hypertensive patients demonstrated impaired left ventricular systolic function compared to both old and young normotensive subjects. The impaired systolic function was associated with less augmentation in systolic indices during exercise compared with resting values in young and elderly hypertensive patients, and to a lesser degree in the normotensive elderly when compared with young normotensives. These data indicate that at rest, left ventricular systolic function may be compromised in hypertensive patients with left ventricular hypertrophy and, to a lesser extent, in the normotensive elderly. However, other factors in chronic hypertension may contribute to abnormal systolic function and override the effects of aging alone.
