As you might already know, both types of muscle action are equally important for the muscle building process, and muscles actually produce the biggest amount of force during the eccentric part of the movement.

Some studies have indicated that electroencephalography (EEG)- derived movement - related cortical potentials (MRCPs) are greater during eccentric muscle actions than in concentric contractions (Fang et al. 2001; 2004).

Voluntary activation is lower during eccentric muscle actions compared to during concentric muscle actions (Westing et al. 1990; Amiridis et al. 1996; Beltman et al. 2004), although some studies have suggested that this effect is limited to untrained people, and that trained individuals are able to reduce this eccentric - specific deficit (Amiridis et al. 1996).

To date, muscle moment arm studies using cadavers or computerised models have not been able to provide data on the moment arm lengths of the trapezius during its primary actions.

With the shoulder and triceps getting large pieces of the action during a bench press, there simply isn't a better upper body exercise for muscle gain.

E.J. Higbie at University of Georgia tells us, «Greater maximum force can be developed during maximal eccentric muscle actions than during concentric.»

Test - re-test reliability is greater during submaximal compared to maximal muscle actions, when comparing with a single day compared to between days, and when using visual feedback about force levels being produced.

When muscles are lengthened or shortened, this seems to alter the cross-sectional area of the muscle fiber, which probably changes muscle conduction velocity (Kamen & Caldwell, 1996) and may also change the geometry of the particular region of the muscle being measured during the muscle action.

However, whether the same normalization method is appropriate for high speed muscle actions is less clear (Ball & Scurr, 2013), particularly as it is common to find percentages of EMG that are > 100 % of MVIC during high velocity sports movements such as sprint running (Kyröläinen et al. 2005; Liebenberg et al. 2011).

The linearity of the relationship between the size of the EMG amplitude recorded and the force produced during isometric or slow, controlled dynamic muscle actions is unclear.

There are preliminary indications that hip adductor strengthening programs may be beneficial for reducing the incidence of adductor - related groin strain injury (Engebretsen et al. 2008; Hölmich et al. 2010; see review by Esteve et al. 2015) and also that wearing compression shorts may be beneficial for reducing the load on the adductor longus during return to sport post-injury, by virtue of reducing the muscle activity during cutting actions (Chaudhari et al. 2014).

An EMG amplitude can therefore be taken as a global measure of motor unit activity during the muscle action being performed.

When using surface electrodes, the equipment detects the voltage in any number of muscle fibers that are close to the surface of the skin, which may or may not be innervated quasi-randomly at any given moment during a muscle action (Reaz et al. 2006).

Assessing the effect of bench press muscle action and region, Newton et al. (1997) found that a greater concentric average velocity was achieved at all loads between 15 — 90 % of 1RM during the bench press throw when preceded by the eccentric muscle action compared to the concentric - only muscle action.

It therefore showed that the aspects of an exercise that determine transfer to sport are not limited to the movement pattern, but include other factors such as the muscle group being trained (the hamstrings are key to sprinting ability), and the mode of the contraction (eccentric muscle actions are very important during sprinting).

Also, there is a difference between the shortening and lengthening phases, with EMG amplitude being lower for the same force output during lengthening muscle actions compared to similar shortening muscle actions (Disselhorst - Klug et al. 2009).

This is because EMG amplitude represents the extent to which the individual motor units within a muscle are active during a joint action.

In practice, this means that drawing inferences about the muscle force that might be produced during fatiguing muscle actions is not appropriate.

This builds on older work finding that increasing loads during carrying actions increases gluteus medius muscle activity (Neumann and Cook, 1985; Neumann et al. 1992), particularly when loads were carried unilaterally rather than bilaterally (Neumann et al. 1992) or on the contralateral side rather than on the ipsilateral side (Neumann and Cook, 1985).

Van den Tillaar & Ettema (2009) found that no difference existed between the triceps brachii muscle activity between successful and unsuccessful 1RM attempts or between periods (pre-sticking, sticking and post sticking) during concentric muscle actions.

Concerns over validity aside, it has been proposed that P - EMG provides a good indicator of the maximal EMG amplitude during performance of the muscle action, while A-EMG provides a better indicator of the overall EMG amplitude averaged across the whole movement (Hibbs et al. 2011).

The waveform can be taken as a global measure of motor unit activity during the muscle action being investigated (Farina et al 2004b).

In fact, our muscles are actually stronger during eccentric muscle actions!

The muscle activity of the medial and lateral regions of the latissimus dorsi are affected by muscle action (e.g. medial region greater during lateral trunk bending, lateral region greater during rowing).

On the other hand, many other researchers have reported that the EMG amplitudes of the prime movers are lower under unstable conditions than under stable conditions, both during isometric (McBride et al. 2006; Chulvi - Medrano et al. 2010) and dynamic (Kohler et al. 2010; Chulvi - Medrano et al. 2010; Saeterbakken & Fimland, 2013c; Andersen et al. 2014) muscle actions.

The researchers suggested that these findings imply that hip flexor length affects gluteus maximus and hamstrings EMG amplitudes during squatting motions, at least during eccentric muscle actions.
