Comparing the stiff - legged deadlift with the leg curl and back squat, Wright et al. (1999) found that there was little difference between the stiff - legged deadlift and the leg curl but both the stiff - legged deadlift and
leg curl produced greater hamstrings muscle activity than the back squat.
Not exact matches
Doing a single set of squats will
produce more growth that 4 - 5 sets of
leg curls.
The hams are large muscles mostly comprised of fast - twitch fibers, which means that they can
produce lots of force and training them once a week with a couple of sluggish sets of
leg curls would be disrespectful to their power.
This is the same finding as for resistance training exercises, where isolated knee flexion exercises (such as
leg curls)
produced the best results with the greatest regularity.
Additionally, isolation exercises such as the glute - ham raise and prone
leg curl appear to be effective (and in some cases) superior exercises for
producing high levels of erector spinae muscle activity compared with some other isolation and compound exercises.
Oliver and Dougherty (2009b) compared the hamstrings EMG amplitude
produced by the Razor
curl and the
leg curl.
The plank with arm reach, side plank with arm reach, and the birddog with elastic resistance
produced greater external oblique muscle activity compared to the
curl up with bent
legs.
They found that the Razor
curl produced similar levels of hamstring EMG amplitude to the
leg curl.
Comparing hamstring strain injury prevention and rehabilitation exercises, Orishimo & McHugh (2015) found that the supine sliding
leg curl (Slider)
produced greater gluteus maximus EMG amplitude during the eccentric phase than the standing elastic - band resisted hip extension, the standing trunk flexion (Glider) or the standing split (Diver).
