Here is another thought on your athlete’s interset rest/recovery period. How about isometrics in the rest period as a way to maximise hypertrophic adaptation?
You might want to consider such practice as Schoenfeld et al. (2020) reported significantly increased hypertrophy of the mid-thigh in a group which trained with isometric holds (30 secs) in the interset rest period. There was a catch however, it was reported that the isometric holds had a detrimental effect on leg press strength gains.
As you can see there is a bit of a theme over some of my previous posts in that keeping athletes/players busy during the interset rest period is most likely beneficial for hypertrophic adaptation. Its benefits for strength gains especially via neuronal mediated adaptation however, is questionable. Nonetheless, you might want to think about this type of interset training if you are returning athletes from injury, and atrophy of the affected muscle is an issue.
