Publicly accessible short-read RNA sequencing (SRS) of clinical exercise studies were extracted from the Gene Expression Omnibus. Oxford Nanopore long-read RNA sequencing (LRS) was performed on mouse gastrocnemius before and following treadmill exercise. Differential gene expression (DGE), differential alternative splicing (DAS), and differential isoform expression (DIE) were analyzed. Gel-based/droplet digital RT-PCR and western blots were performed to validate expression changes of select genes. Both SRS and LRS illustrated significant DGE in skeletal muscle post-exercise, whereby 89 RBPs were significantly up-/down-regulated. rMATS analysis of SRS data revealed that exon-skipping and intron-retaining splicing events were the most common. Swan analysis of LRS data revealed 61 RBPs with significant isoform switching: one of these RBPs, mHnrnpa3, underwent a significant non-coding to protein-coding switch. HnRNP-A3 protein levels validated nearly two-fold increases at 1 hour and 24 hours post-exercise.

The two R codes are related to the feasible balance region calculations for Figures 2, 3, and 4 in the paper.
The MATLAB codes are related to the simulations of the recoverable initial quasi-static states, the results of which are shown in Figure 5 of the paper.
