with increasing load even in elite weightlifters, and Musser et al. (2014) reported that barbell horizontal displacement may be at least partly determined by anthropometry, as barbell horizontal displacement in the first pull was associated with thigh and shank lengths in female Olympic weightlifters.

with increasing load.
They found that EMG amplitude increased
with increasing load in the deltoid only in the second pull, turnover, and recovery phases; in the biceps in the transition, second pull, turnover, and recovery phases; in the triceps only in the recovery phase, in the latissimus dorsi only in the first phase, and not at all in the pectoralis major.
Orloff et al. (1997) assessed the effect of load on peak trunk angle and found that there was no effect
with increasing load.
Power output actually increases
with increasing load in the snatch lift (Hadi et al. 2012) is greater during the snatch lift in the second pull than in the first pull, being around 2,000 — 3,000 W in the second pull phase and 600 — 1,000 W in the first pull phase (Garhammer, 2001; Gourgoulis et al. 2009; Harbili, 2012; Akkuş, 2012; Harbili & Alptekin, 2014).

with increasing load, is greater in males than in females, but smaller in more skilled athletes than in less skilled athletes.
Although peak velocity is less well - studied, linear barbell velocity reduces
with increasing load (Suchomel et al. 2014a), as do the angular velocities of the hip, knee and ankle joints (Suchomel et al. 2014e).
During the deadlift, it appears that trapezius muscle activity is greater
with increasing load while deadlift type or grip technique has no effect.
Enoka (1988) explored hip, knee and ankle joint power outputs in competitive weightlifters during the first pull and transition phases and reported that joint peak power output did not alter
with increasing load at the hip, knee or ankle.
Maximum barbell vertical displacement prior to the catch in the snatch lift ranges between 1.0 — 1.3 m (Baumann et al. 1988; Garhammer, 1985; Garhammer, 2001; Campos et al. 2006; Gourgoulis et al. 2002; 2004; 2009; Okada et al. 2008; Akkuş, 2012; Harbili, 2012; Ho et al. 2014; Harbili & Alptekin, 2014) but decreases
with increasing load (Garhammer, 1985; 2001; Hadi et al. 2012) and is greater in males than in females (Gourgoulis et al. 2002) but smaller in more skilled athletes than in less skilled athletes (Burdett et al. 1982).
