1. Cycling & Prostate Health: Debunking the Myths

This is the most common question we hear in Colmar, a region famous for its cycling: “Is cycling bad for my prostate?”

The Reality: No, cycling does not increase the risk of prostate cancer or an enlarged prostate (BPH). However, intensive riding can cause perineal compression.

• The Symptoms: Numbness, tingling, or pain in the perineal area.
• The Solution: Choose a “cut-out” saddle (with a central opening) to relieve pressure on the urethra and nerves. Also, ensure your saddle is perfectly level.

2. Blood in Urine After Exercise: Should You Worry?

Some long-distance runners or athletes in high-impact sports (like rugby or boxing) occasionally notice pinkish urine after an intense session. This is known as exercise-induced hematuria.

While often caused by micro-trauma to the bladder wall (which “jostles” during a run, especially if empty), caution is key.

The Golden Rule: Any presence of blood in the urine—even if painless and seemingly linked to exercise—requires a urological evaluation to rule out underlying causes such as stones or polyps.

3. High-Impact Sports & Bladder Control

Stress urinary incontinence isn’t just for seniors. It affects many female athletes (CrossFit, running, trampolining) due to high intra-abdominal pressure.

• The Message: It is not an inevitable part of being an athlete.
• The Action: Specific pelvic floor physical therapy and learning “pelvic protection” techniques during exercise allow you to stay active without discomfort.

4. Hydration Protocol: Your Shield Against Kidney Stones

Dehydration is the number one risk factor for kidney stones in athletes. During hot summers, vigilance is vital.

Here is the protocol recommended by our experts to keep your kidneys healthy:

A. Pre-Workout (Anticipation)

Never start a session if your urine is dark.

• 2 Hours Before: Drink 500 ml of water. Your urine should be pale yellow (like lemonade).

B. During Workout (Maintenance)

The stomach can only absorb about 600 to 800 ml per hour.

• The Rhythm: Take 2 to 3 sips (150-200 ml) every 15 to 20 minutes.
• The Choice: For efforts lasting over an hour, add a pinch of salt to your bottle to compensate for sodium loss.

C. Post-Workout (The “Rinse”)

This is the critical window where crystals can aggregate in the kidneys.

• The Rule: Drink 1.5 times the weight lost within the following 2 hours.
• The Urologist’s Tip: Add fresh lemon juice to your recovery water. The citrate it contains is a powerful natural inhibitor against stone crystallization.

Summary

Exercise is your best ally, but it requires paying attention to your body’s urological signals. Whether you are cycling through the Alsace vineyards or hiking the Vosges trails, remember to hydrate consistently.
