The advantages of linear vs non-linear periodisation is a popular strength training topic. There is (some) evidence that non-linear periodisation is better than linear periodisation for strength improvements both in untrained and trained subjects, and some coaches find that it is easier to fit in a non-linear program during “the season” (i.e. when the athletes are doing what they are supposed to be doing).
There is of course many ways to program a non-linear periodisation. Some feel that the daily program should be determined by a pre-exercise test of readiness, other just prescribe a different set range for each training day (e.g. Day1: 8-12, Day2: 3-5, Day 3: 12-15) or prescribe different training modalities for each day (e.g. Day1: Max-Effort, Day2: Power, Day3: Sub-maximal).
(As usual, the precision which with the different programs are prescribed exceeds the knowledge about the differences in outcome with quite a bit.)
I have found very little on the topic of non-linear periodisation for isometric strength training. Has anyone tried something similar for deadhangs? For example: Day1: 5 x 10s, Day2: 2x3 x 5s, Day 3: 3x20s?
