Monitoring the degree of stress and muscle breakdown caused by intense resistance training and early detection of rhabdomyolysis, a serious condition where damaged muscle cell contents are released into the blood Assessing liver health and function as the liver bears a high metabolic load due to proteins and common dietary supplements in this sport Evaluating kidney efficiency in eliminating protein metabolism byproducts such as urea and creatinine, especially with high-protein diets Measuring cortisol levels as chronic elevation due to training or psychological stress can impede muscle building and increase muscle breakdown Providing an overview of metabolic health through triglycerides and complete blood count

Bodybuilders and amateur weightlifters who lift heavy weights regularly Individuals following high-protein diets or taking sports supplements (protein, creatine, etc.) Beginners who rapidly increase training intensity and are at risk of muscle injuries Athletes experiencing persistent fatigue or poor recovery after exercise Individuals with severe muscle pain and dark-colored urine after exercise

Severe and unusual muscle pain (extreme stiffness) lasting more than 72 hours after exercise Dark-colored urine (tea or cola-colored) after an intense training session, a warning sign of rhabdomyolysis General fatigue and persistent exhaustion with difficulty recovering between training sessions Yellowing of the eyes or skin, or pain in the upper right abdomen (possible liver issues) Before starting a new intensive training cycle or afterward for comparison and monitoring

Total creatine kinase (CK): at rest, usually ranges between 30-200 U/L, after intense exercise it may rise to 500-1000 or more, values above 5,000 are of significant concern Creatinine: may be slightly higher than the general average due to large muscle mass, which produces more creatinine Liver enzymes (ALT, AST): should be interpreted cautiously and in relation to rest periods from exercise Cortisol: has a daily rhythm, highest in the morning, and rises with chronic stress Triglycerides: desirable < 150 mg/dL

Q: Frequently Asked Questions (FAQs)

What is rhabdomyolysis and why is it important for bodybuilders? Rhabdomyolysis is a medical emergency where skeletal muscle fibers are severely damaged and release their contents, such as myoglobin and enzymes, into the bloodstream Myoglobin can block kidney tubules and cause acute kidney failure Symptoms include severe muscle pain, weakness, and dark-colored urine Excessive intense training, especially in beginners or after a break, is a common cause A massive elevation in CK enzyme (over 5,000–10,000 U/L) is a key indicator Why measure CK-MB if the focus is on skeletal muscles? CK-MB is the isoenzyme primarily found in heart muscle In severe rhabdomyolysis, CK-MB may rise slightly because a small amount is also present in skeletal muscles The main benefit is differentiation: if total CK is extremely high and CK-MB is also significantly elevated, it may indicate a concurrent cardiac injury (rare) requiring further evaluation In skeletal muscle injuries, the CK-MB to total CK ratio is usually low (<5%) Does elevated liver enzymes (AST, ALT) always mean liver problems? No, especially in this sport AST is abundant in skeletal muscles as well After intense resistance training, AST rises mainly due to muscle injury, not necessarily the liver Abstaining from exercise for 72 hours before testing is necessary to identify the true source of elevation ALT rises more specifically for the liver

Precise monitoring of muscle enzymes, liver, and cortisol levels to ensure effective weightlifting without compromising your vital health and recovery.

Scientific name: Basic Bodybuilding Monitoring Package

A laboratory package specifically designed for gym-goers and weightlifting enthusiasts. It focuses on assessing muscular and metabolic stress by measuring total creatine kinase and its cardiac isoform (CK-MB) as indicators of muscle tissue health and injury, and liver enzymes (ALT, AST) which rise with muscular and liver stress. It also includes as...

Service type Laboratory test (Blood)

Duration 10-15 minutes

Fasting Fasting is not required

Included Services

Assessment of muscle stress and tissue injury (total creatine kinase CK and CK-MB analogue).
Liver function tests (ALT and AST enzymes and total bilirubin).
Kidney function assessment (creatinine and urea nitrogen BUN).
Measuring total cortisol hormone as an indicator of overall stress and hormonal balance.
A complete blood count (CBC) and a triglyceride level test.
Consult a sports medicine or internist for a comprehensive interpretation of the results.

Normal Levels

Total creatine kinase (CK): at rest, usually ranges between 30-200 U/L, after intense exercise it may rise to 500-1000 or more, values above 5,000 are of significant concern
Creatinine: may be slightly higher than the general average due to large muscle mass, which produces more creatinine
Liver enzymes (ALT, AST): should be interpreted cautiously and in relation to rest periods from exercise
Cortisol: has a daily rhythm, highest in the morning, and rises with chronic stress
Triglycerides: desirable < 150 mg/dL

Conditions & Notices

Mandatory fasting: You must fast for 10-12 hours before the sample is taken for accurate triglyceride testing. Water is permitted.
Complete abstinence from exercise: Avoid any strenuous physical activity or training for at least 72 hours (3 days) prior to the test. This is crucial to ensure that muscle enzymes (CK, AST) return to their baseline levels and to avoid misleading results.
Timing of cortisol sample collection: Blood should be drawn early in the morning (7-9 am), when cortisol levels are at their daily peak.
Adequate hydration: Drink normal amounts of water before the test, as dehydration can raise creatinine and urea levels.
Stop taking supplements: Stop taking sports supplements (especially creatine, steroids) 5-7 days before the test after consulting a doctor.
