peak vertical barbell velocity (1.72 vs. 1.82 m / s).
However, increases in muscle fascicle length are also likely dependent on the mechanical
load incurred by the prime mover, as knee flexion (hamstring only) exercise seems to lead to greater adaptations in the hamstrings than hip extension (hamstring, gluteus maximus, and adductor magnus) exercise, even
when muscle length at
peak contraction is shorter (Bourne et al. 2016).
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).
And assuming that maximal bar speed is attempted, this produces a different
peak velocity for the same force
when using each external
load type.
In contrast, they found no difference in
peak bar velocity at all
loads except 75 % of 1RM
when comparing the bench press throw immediately preceded by a fast eccentric muscle action and the concentric - only muscle action condition.
Comparing the effects of different training variables, Swinton et al. (2011a) found that there was no difference in
peak knee joint angles
when using relative
loads ranging between 10 — 80 % of 1RM with the straight bar and hexagonal bar deadlifts.

Modeling has also shown that it's relatively inexpensive to increase the reliability of the total wind output to a level equivalent to a coal - fired power station by adding a few low - cost
