Source notes

Mobility work takes time in an athlete's training week, so it matters whether that time helps performance as well as movement. Across 22 studies, programmes involving dynamic stretching, yoga, Pilates, dance or combinations of stretching generally improved or maintained at least some performance measures. The participants were mainly junior or young adult athletes. Twenty studies showed some benefit or maintenance under the authors' broad criteria, while two showed no meaningful impact. The results covered strength, jumping, speed, balance and sports skills; they were not combined into a single pooled improvement.

The encouraging pattern does not establish one best mobility method. Some studies found improvements within a training group without a clear advantage over its comparison group. Controls often continued routine training without the added mobility work. Programmes also involved strength, balance or movement practice, so a performance gain could not necessarily be attributed to greater range of motion alone. Many studies did not measure that change directly.

How Does This Show Up in Real Life?

A coach choosing mobility work can ask which movement the athlete needs to perform better, rather than selecting a routine only because it increases flexibility. The authors recommend exercises relevant to the sport and monitoring changes in range of motion. A controlled movement through a joint's available range may serve a different purpose from simply holding a stretch. The evidence supports considering mobility alongside existing conditioning, with the choice and timing shaped by the training schedule. Keeping performance stable during a busy competition period can also matter, even when a test score does not improve. However, these findings do not show that mobility should replace strength or skill training, or that every athlete needs the same style or amount.

The studies were small and generally of moderate to low quality. Only one confirmed that outcome assessors were blinded. The variety of sports, exercises and tests prevented a meaningful pooled analysis. Apart from one eight-month study, programmes averaged about seven weeks. Lasting benefits after training stops remain uncertain, and no studies included masters athletes, limiting conclusions for older competitors.

This is a reason to consider well-chosen mobility work as part of athletic preparation, with realistic expectations. The evidence is more useful for identifying possible additions to a programme than for promising a particular performance gain or ranking yoga, Pilates and stretching against one another.
