And this explains why the patterns of joint angle - specific strength gains differ
between isometric training with either long or short muscle lengths: they are caused by different adaptations.
Not exact matches
An influential 21 - week study by Ahtiainen J.P. et al. showed a correlation
between T levels and the changes in
isometric strength and muscle size, which means that both serum basal testosterone concentrations and
training - induced acute testosterone responses are strongly associated with muscle and strength gains.
Instead of performing one
isometric hold of 15 seconds, as some lifters do, you can do five seconds, then four, three, and so on, while the reps you do in
between train the muscles through a full range of motion.
Similarly, if full range of motion
training with free weights is similar to
isometric training with long muscle lengths, then we should see parallels
between those two types of
training, as well.
The easiest way to understand how these factors drive the differences in adaptations
between full range of motion
training and partial range of motion
training, is to look at
isometric training at either short or long muscle lengths.
Studies exploring
isometric training at different muscle lengths have identified differences in regional hypertrophy
between training groups, but not always in muscle fascicle length (Noorkõiv et al. 2014).
I
train with these workouts every other day and in the days in -
between, if they are not rest days, I will add a workout C, where I will practice
isometrics, endurance, locomotion or a combination of these.
