For bodybuilders, achieving peak performance isn’t just about lifting weights and eating right; it’s also about understanding the intricate workings of their bodies. While rigorous training and meticulous nutrition are cornerstones of success, understanding what’s happening inside your body on a biochemical level can make all the difference between hitting plateaus and achieving breakthroughs. In this article, we explore why blood testing is not just beneficial but essential for bodybuilders looking to optimise their performance, recovery and long-term health.

Why bodybuilders NEED bloodwork

Bodybuilders subject their bodies to intense physical demands, which can impact hormone levels, nutrient balance and overall organ function. Blood testing provides 5 important benefits:

1. Optimised Performance: Blood testing helps bodybuilders optimise hormone levels, such as testosterone and oestradiol, critical for maximising muscle growth, strength gains, and overall athletic performance.

2. Enhanced Recovery: By monitoring markers like C-Reactive Protein (CRP) and assessing nutrient levels (e.g., vitamin D, iron), bodybuilders can manage inflammation more effectively and support quicker recovery times between intense training sessions.

3. Health Monitoring: Regular blood tests provide insights into organ function (e.g., liver, kidney) and cardiovascular health (lipid profiles), allowing bodybuilders to proactively manage potential health risks associated with high-intensity training and dietary requirements.

4. Personalized Nutrition and Supplementation: Blood testing identifies nutrient deficiencies (e.g., vitamin B12) and metabolic markers (e.g., thyroid function), enabling bodybuilders to tailor their nutritional intake and supplementation plans to meet specific training goals and enhance overall well-being.

5. Long-Term Sustainability: By understanding their body’s biochemical responses through blood testing, bodybuilders can adopt sustainable training practices and lifestyle adjustments that support long-term health, performance, and longevity in their athletic careers.

Which tests should bodybuilders use and why?

Testosterone (Free/Total) + SHBG: Regulates muscle mass, strength, and recovery. Monitoring these levels helps optimize performance and hormone balance.

Elevated levels can result from anabolic steroid use, which increases testosterone levels beyond natural limits. Conversely, low levels may indicate overtraining, stress, or inadequate recovery.

FSH & LH: Stimulate testosterone production and are crucial for reproductive health and hormonal equilibrium.

Elevated levels may suggest the body’s attempt to stimulate testosterone production. Low levels can indicate suppressed production due to exogenous testosterone use.

Oestradiol: Important for bone density, cholesterol regulation, and managing water retention.

Elevated levels can occur due to aromatization of excess testosterone into oestrogen, often seen with steroid use. Low levels may occur with inadequate fat intake or excessive exercise.

Lipid Studies (Cholesterol, Triglycerides, HDL & LDL): Vital for cardiovascular health and energy metabolism, critical during intensive training phases.

Anabolic steroids can impact cholesterol levels, leading to elevated cholesterol and triglycerides. HDL (“good cholesterol”) may decrease, while LDL (“bad cholesterol”) may increase, predisposing to cardiovascular disease.

Thyroid Function Tests (TSH, FT4, FT3): Regulate metabolism, energy levels, and overall muscle function optimization.

Anabolic steroids can alter thyroid hormone levels, potentially leading to thyroid dysfunction. Elevated or suppressed TSH, FT4, or FT3 levels may indicate thyroid gland disruption.

Kidney Function (EUC): Monitor electrolytes and kidney health, essential for filtering metabolic waste and maintaining fluid balance.

Intense training and anabolic steroid use can stress the kidneys, resulting in elevated creatinine and urea levels. Abnormal electrolyte levels may also occur, affecting fluid balance.

Full Blood Count (FBC): Provides insights into oxygen-carrying capacity, immune function, and overall health.

High-intensity training can cause temporary changes in red blood cell count (e.g., elevated hematocrit), reflecting increased oxygen demand. Persistent elevation may indicate dehydration, overtraining, or underlying health issues.

C-Reactive Protein (CRP): Indicates inflammation levels, impacting recovery and injury prevention.

Elevated CRP levels indicate inflammation, which can result from intense training, muscle damage, or infection. Chronic elevation may suggest ongoing tissue stress or injury.

In conclusion, integrating regular blood testing into your bodybuilding regimen isn’t just about optimising performance; it’s about safeguarding your health and ensuring sustainable progress. By leveraging these targeted tests, bodybuilders can tailor their training and nutrition plans more effectively, while proactively managing potential health risks associated with rigorous physical training. Embrace the power of knowledge with blood testing and unlock your true potential as a bodybuilder.
