Leaking During Exercise: The Athlete Problem Nobody Talks About

A problem hiding in plain sight

Surveys of female athletes have repeatedly found that a substantial proportion (in some studies of high-impact sports, a majority) experience urinary leakage during training or competition. It is most common in running, gymnastics, trampolining, CrossFit-style training, and heavy lifting. Almost none of them mention it to anyone. Many quietly modify or abandon activities they enjoy, and the reason rarely gets recorded as what it actually is.

Being fit does not protect you

This is the part that confuses people most. Leakage is not a marker of being out of shape, some of the most affected people are among the fittest. The mechanism explains why. Every landing, every jump, and every heavy lift generates a spike in intra-abdominal pressure that has to be resisted by the pelvic floor. Athletes generate far larger and far more frequent pressure spikes than sedentary people. If the pelvic floor cannot match that load at the exact moment it occurs, you leak. The pelvic floor has to keep pace with the rest of your training, and it is almost never trained deliberately.

Timing matters as much as strength

A pelvic floor contraction has to be automatic and correctly timed, a fraction of a second before impact, not something you consciously initiate. Many athletes have adequate raw strength but poor reflexive timing, so the contraction arrives late. That is a neuromuscular coordination problem rather than a strength problem, and it explains why simply doing more kegels often fails to help. It also explains why leakage can appear suddenly after a training change: a new movement pattern outpaces the timing you had.

Breath-holding and bracing make it worse

Heavy lifting technique frequently involves the Valsalva manoeuvre, holding your breath and bracing hard. That is effective for spinal stability and it drives significant downward pressure into the pelvic floor. Combine habitual bracing with a pelvic floor that is not matching the load and leakage becomes predictable. This does not mean you should stop lifting; it means the pelvic floor needs to be part of the training conversation.

What Emsella offers active patients

The practical appeal is that it requires no technique on your part and no time out of training. A 28-minute session produces roughly 11,000 supramaximal contractions while you sit fully clothed, engaging the whole pelvic floor rather than the portion you can consciously isolate. For athletes, the neuromuscular re-education is arguably as valuable as the strength gain, improved recruitment and timing is what shows up during a landing. Training continues throughout; there is no recovery period.

When the floor is too tight rather than too weak

An important caveat specific to athletes. Some highly trained people, particularly those who brace constantly, have a hypertonic pelvic floor, chronically over-contracted, unable to fully relax, and consequently unable to generate a strong contraction when needed. That presentation can also leak, and strengthening it further is the wrong answer. Distinguishing weak from tight requires assessment, and it is a real reason not to self-prescribe.

Practical adjustments meanwhile

Empty your bladder before training rather than mid-session. Look at whether leakage is specific to particular movements, double-unders and box jumps are common triggers, and scale those temporarily rather than stopping altogether. Reconsider habitual breath-holding on submaximal lifts. And stop treating it as an inevitable cost of being active; that framing is the reason so few people address it.

You do not have to modify around it

The most common outcome we see is women who had quietly stopped running, or stopped a class they liked, going back to it. Book a consultation at our Cambridge practice for an assessment of whether your pelvic floor is weak, poorly timed, or overly tight, because the answer changes the plan entirely.
