For example, when comparing constant load (free weight) and constant resistance (pneumatic machine) bench presses, the constant resistance bench presses involve
higher peak velocities, because they allow greater acceleration at the start of the movement (Frost et al. 2008).
The high pull and hang high pull displays
the highest peak velocity with low loads (30 % of 1RM hang power clean), the highest force with high loads (80 % of 1RM hang power clean), and the highest peak power with moderate loads (45 % of 1RM hang power clean).

# 3 Lifting: Snatch and snatch variation — hang snatch, power snatch, snatch pulls and
high pulls — seem to provide a better chance of increasing
peak vertical bar
velocity, a distinctive feature that ultimately reflects the ability to generate and apply force over a longer period of time (special strength training).
Jump shrugs display greater
peak power output,
peak force,
peak velocity, and
peak angular
velocities than the hang clean and
high pull.
The jump shrug displays
highest peak power outputs,
peak velocity,
peak joint angular
velocities,
peak vertical displacement, and
peak landing forces with low loads (30 — 40 % of 1RM hang power clean).
On the other hand, if you measure force in the late phase (say around 300ms), after force has reached its
peak (e.g. Behm & Sale, 1993), then you will see a change in
peak force only if force production at
high velocities has altered.
In the snatch lift as performed in competition,
peak vertical bar
velocity can reach 2.1 m / s (Garhammer, 1985; Okada et al. 2011) and the second pull is the fastest phase of the lift (Campos et al. 2006; Harbili, 2012; Korkmaz & Harbili, 2012; Akkuş, 2012; Harbili & Alptekin, 2014; Harbili, 2015), although
peak vertical bar
velocity is even
higher with sub-maximal loads (Hadi et al. 2012).
The
highest peak linear
velocity and joint angular
velocities are achieved with the lightest loads.
Comparing the hang clean, jump shrug, and
high pull, Suchomel et al. (2014a; 2015d) found that the jump shrug produced greater
peak power output,
peak GRF, and
peak velocity than either the hang clean or the
high pull, although the force - time curves are similar across the first 80 % of the movement (Suchomel et al. 2015d).
Comparing the hang power clean, jump shrug, and
high pull, Suchomel et al. (2014a; 2015d) found that the jump shrug produced greater
peak power output,
peak GRF, and

They found that
peak power,
peak bar
velocity, and maximum bar displacement occurred with the lowest load tested (40 % of 1RM power clean) while
peak force and impulse occurred with the
highest load tested (140 % of 1RM power clean).
The
high pull also produced greater
peak power output and
peak velocity than the hang clean.
In contrast, using either constant resistance or variable resistance (which both increase
peak bar speeds) could be helpful for improving force at
higher velocities.
Acceleration is always
high at the start of the movement, zero when the barbell reaches
peak velocity, and negative at the end of the movement.
So inertia is also
high at the start of the movement, zero when the barbell reaches
peak velocity, and negative at the end of the movement.
The IMF Bz component turned southward, remained south between 05:32 UT and 08:20 UT on May 15 reaching a value of − 44 nT at 05:56 UT and the
