On the other hand, regional hypertrophy (but not always muscle fascicle length) seems more important than changes in joint angle - specific neural drive for the joint angle - specific gains in strength
after isometric training at long muscle lengths (Alegre et al. 2014; Noorkõiv et al. 2014).
Traditionally, it has been assumed that neural factors were responsible for joint angle - specific gains in strength
after isometric training at all joint angles (Kitai & Sale, 1989; Noorkõiv et al. 2014).
And joint angle - specific strength gains are smaller than
after isometric training at short vs. long muscle lengths.
Since these results are not unusual, there is clearly a different type of joint angle - specific strength gains
after isometric training with short muscle lengths, compared to
after isometric training with long muscle lengths.
Overall, there is a slightly different pattern of joint angle - specific strength gains
after isometric training with either short or long muscle lengths.
Not exact matches
Although there is good evidence for velocity - specificity occurring
after dynamic strength
training, some studies have also shown that strength
training with «explosive»
isometric contractions produces different results from «sustained» maximal force
isometric contractions.
Overall, EMG amplitude in maximum voluntary
isometric contractions does not appear to be altered differently
after high - force or high - force - intent
training, compared to
after high - velocity or explosive - intent
training (Lamas et al. 2012; Tillin & Folland, 2014; Balshaw et al. 2016).
In one study, Remaud et al. (2010) assessed joint angle - specific changes in maximum voluntary
isometric contraction (MVIC) torque and in neural drive
after isotonic and isokinetic types of external load, using knee extension
training.
So eccentric
training is helpful for preventing muscle strains, but this may be partly because of various specific changes that happen
after eccentric
training, including specific gains in eccentric strength (relative to
isometric or concentric strength) and not just because of overall strength gains.
After her studio closed, the pair adapted her methods as Physique 57 ®, a combination of interval
training,
isometric exercises and orthopedic stretches that aims to lengthen and sculpt muscles for a lean body.
