Sport climbing improves the speed of the Instrumented Stand and Walk Test. Box plots for each test point (before the intervention = baseline, and after the intervention = after 12 weeks) show the respective median, minimum, maximum and the first and third quartiles of the speed of the ISAW in meters per second in 22 Parkinson’s Disease participants (H&Y 2–3) after a 12-week sport climbing intervention (SC) compared to a control group of 24 PD participants (H&Y 2–3) who performed unsupervised physical activity (UT). The SC showed a significant increase in speed of the ISAW (baseline: 0.9 m/s, 12 weeks: 1.0 m/s, p < 0.001), while the UT did not (baseline: 1.0 m/s; 12 weeks: 1.0 m/s).
