Hey fitness coaches! Let's have a real talk about something that should be on your radar - rhabdomyolysis, or rhabdo for short. I know, I know...that word sounds like a mouthful. But trust me, you don't want to miss the signs of this potentially serious condition in your online clients.

If you've ever had a client message you in a panic because they noticed red or brown discoloration in their urine after an intense training session, it's quite likely they were experiencing rhabdo. And before you think "Ah, it's probably no big deal" - it absolutely warrants your immediate attention.

What Exactly Is Rhabdomyolysis?

What Exactly Is Rhabdomyolysis?

Rhabdo is a syndrome where damaged skeletal muscle fibers rapidly break down and leak their contents, like myoglobin proteins, into the bloodstream. If severe enough, this muscle damage can cause complications like acute kidney injury as the kidneys struggle to clear the excessive myoglobin from the body.

While rare, rhabdo has to be taken seriously in the fitness realm because overexertion from extreme exercise routines is one of the leading triggers, especially if the person is new to that level of intensity.

The ‘classic’ triad of symptoms includes muscle pain (23% of patients), weakness (12% of patients) and dark urine (Coca-cola colored or tea-colored, 10% of patients).

Who's At Risk for Rhabdo?

Risk for Rhabdo

No client is completely immune, but there are some key risk factors that increase susceptibility:

Out of Shape Beginners

De-conditioned individuals who jump into a way-too-intense workout routine they're nowhere near prepared for are prime candidates, especially if they have underlying health issues like diabetes, thyroid disorders, or are dehydrated.

Experienced But Overzealous Clients

Even very fit clients aren't exempt - overly gung-ho folks who attempt personal record lifts or mile times may end up in the rhabdo danger zone if they completely overtrain and obliterate their muscles in the process.

Those With Certain Health Conditions

Some genetic muscle disorders like McArdle's disease can make folks hypersensitive to exercise-induced rhabdo. Other conditions like sickle cell trait also increase the risk.

Classic Rhabdo Symptoms to Watch For

Fitness client and coach

While the telltale sign of rhabdo is discolored urine ranging from pinkish-red to cola brown due to the myoglobin dump, there are other red flags:

- Excruciating, widespread muscle pain and  extreme muscle weakness 

- Muscle tenderness and swelling in affected areas

- Nausea, vomiting, and abdominal pain

- Confusion, odd behavior, and fatigue (indicating kidney issues)

The sooner you can get a client showing these symptoms to head to the ER for IV fluids to flush the kidneys and supportive treatment, the better their prognosis will be.

How to treat it?

How to treat Rhabdomyolysis?

Here are some common ways to treat rhabdomyolysis:

1. Aggressive intravenous fluid therapy: Large volumes of intravenous fluids, such as normal saline or lactated Ringer's solution, are administered to induce diuresis and flush out myoglobin from the kidneys, reducing the risk of acute kidney injury.

2. Alkalinization of urine: In some cases, sodium bicarbonate may be given intravenously to alkalinize the urine, which can help facilitate the excretion of myoglobin.

3. Electrolyte correction: Potassium, calcium, and phosphate levels are monitored and corrected as necessary, as they can become imbalanced due to muscle breakdown.

4. Mannitol: This diuretic agent may be administered to increase urine output and help flush out myoglobin.

5. Pain management: Medications such as NSAIDs or opioids may be given to alleviate muscle pain and discomfort.

6. Dialysis: In cases of severe acute kidney injury or electrolyte imbalances, dialysis (hemodialysis or continuous renal replacement therapy) may be necessary to remove myoglobin and correct metabolic abnormalities.

7. Treating the underlying cause: Identifying and addressing the trigger for rhabdomyolysis, such as trauma, excessive exercise, medications, or infections, is crucial to prevent further muscle damage.

8. Rest and monitoring: Allowing the affected muscles to rest and closely monitoring renal function, electrolyte levels, and potential complications like compartment syndrome are essential components of treatment.

CK levels that are five times the upper limit of normal levels are evidence of rhabdomyolysis. Early recognition and prompt initiation of aggressive fluid resuscitation and other supportive measures are critical in managing rhabdomyolysis and preventing potentially life-threatening complications.

Lifestyle Tips to Prevent Rhabdomyolysis

Lifestyle Tips to Prevent Rhabdomyolysis

• Gradual Progression: Increase exercise intensity slowly to allow muscles to adapt.

• Avoid Overexertion: Don't excessively repeat the same muscle movements without rest.  

• Stay Hydrated: Drink plenty of water to maintain proper hydration.

• Listen to Your Body: Respect pain and fatigue signals, don't push past limits.

• Be Mindful of Eccentric Training: Control eccentric muscle lengthening carefully.

• Suitable Environment: Avoid exercising in extreme heat or humidity.  

• Use Supplements Cautiously: Some, like creatine, may affect hydration.

• Minimize Extra Weight: Don't overload muscles with heavy equipment or gear.

• Allow Recovery: Take adequate rest between intense workout sessions.

Summary

Workout recovery- Rhabdomyolysis

Look, as fitness professionals, we never want to see our clients experience an issue as serious as rhabdomyolysis. But the harsh reality is that the very training programs we design to make them fitter can potentially put them at risk if precautions aren't taken. 

By educating yourself on rhabdo's causes, symptoms, and prevention strategies - and openly discussing it with clients so they stay alert - you demonstrate true coaching excellence. Rhabdo is treatable when caught early, so staying vigilant could make a life-saving difference for someone in your care.

FAQs 

1. How common is rhabdo in the fitness world?

It's considered rare, but it does happen, especially among amateur athletes engaging in extreme exertion during events like marathons, CrossFit competitions, military training, etc.

2. What should I do if a client suspects rhabdo? 

Advise them to immediately stop exercising, boost fluid and electrolyte intake, and get an emergency medical evaluation. Provide their medical team details on the workout that precipitated symptoms.

3. Does rhabdo mean permanent kidney damage?

Not necessarily - with proper treatment, most recover full kidney function. But if kidney failure ensues, it can be life-threatening without dialysis.

4. As a fitness coach, can I be liable for a client's rhabdo?

Potentially, if the programming was found to be woefully inappropriate for their ability level warnings were ignored. Proper screening helps mitigate this risk.  

5. How can I prevent rhabdo in my clients?

Start conservatively with beginners, perform thorough assessments, increase intensity slowly, modify for any risk factors, and discontinue workouts at first signs of trouble.
