A standard tempo on a movement like a bench press might be as follows: 2 -0-1, which is 2 seconds down
during the eccentric phase when you're lowering the weight to your chest, no pause (when you change from eccentric to concentric) and 1 second up when you lifting the bar upwards.
In contrast, with the same absolute load (load lifted in both movements equal to 90 % of overhead squat), there was no difference in gastrocnemius muscle activity during the concentric phase yet greater muscle activity
during the eccentric phase when performing the overhead squat.
Not exact matches
When appropriate mechanics are achieved
during eccentric muscle lengthening the proper groove has been established ultimately promoting refined mechanics on the subsequent concentric
phase.
The stretch - shortening cycle is simply the time it takes your muscle to transition from an «
eccentric»
phase, in which a muscle is lengthening (such as
when your foot lands
during running), to a «concentric»
phase, in which the muscle is contracting (such as
when your foot pushes back off the ground).
