Fitness & Training

Fitness & Training Tests help athletes and active adults track the biology behind energy, recovery, and performance. This page brings together core and optional labs you can use to screen for common issues (iron deficiency, low vitamin D, electrolyte balance), support a diagnostic work-up when appropriate, and monitor trends across training blocks.

Start with a core panel—CBC, CMP/electrolytes, lipid panel, A1c or fasting glucose—then add targeted markers like ferritin/iron, vitamin D, thyroid tests, creatine kinase (CK), high-sensitivity CRP (hs-CRP), magnesium, and B12/folate. Labs guide smart choices about fueling, recovery, and follow-up with your clinician. They do not replace a medical exam, imaging, or sports-medicine evaluation if you have symptoms or an injury.

Signs, Situations & Related Needs

  • Energy & stamina: persistent fatigue, heavier legs, slower splits, plateau

  • Recovery strain: lingering soreness, repeated “post-viral” dips, poor sleep recovery

  • Hydration & heat: cramps, dizziness, GI issues during long sessions or in hot/humid conditions

  • Bone & soft tissue: frequent strains or stress-reaction concerns

  • Women’s health: cycle changes, low energy availability, iron questions

  • Training checkpoints: pre-season baseline, mid-season tune-up, post-illness return, altitude or heat blocks
    Seek urgent care for chest pain, severe shortness of breath, fainting, or neurologic symptoms.

Why These Tests Matter

What testing can do

  • Screen for modifiable factors that affect training (iron status, vitamin D, electrolytes, glucose control).

  • Stratify risk for cardiometabolic health (lipids, A1c/glucose) and overuse strain (CK, hs-CRP trends).

  • Monitor progress across cycles to fine-tune fueling, recovery, and medical follow-up.

What testing cannot do

  • Diagnose every cause of fatigue or pain without clinical context.

  • Replace ECG/cardiology work-ups, imaging, or sports-medicine exams when indicated.

  • Guarantee performance outcomes—labs inform decisions; training, sleep, and nutrition still matter.

What These Tests Measure (at a glance)

  • CBC (Complete Blood Count): red/white cells and platelets; screens for anemia or infection. Hydration and training status can shift hemoglobin/hematocrit.

  • Iron Studies (Ferritin, Iron, TIBC/Transferrin, % Saturation): iron stores and transport for oxygen delivery. Ferritin rises with inflammation; pair with symptoms and hs-CRP.

  • CMP (Electrolytes, Kidney/Liver, Proteins): sodium, potassium, chloride, CO2, BUN/creatinine, glucose, AST/ALT, albumin. Hard sessions and dehydration can affect numbers.

  • Lipid Panel (± ApoB, Lp[a]): LDL/HDL/triglycerides; ApoB refines risk; Lp(a) is inherited.

  • Glucose Control (Fasting Glucose, A1c ± Insulin): day-to-day and 3-month averages; informs fueling and recovery.

  • Thyroid (TSH ± Free T4/T3): energy, temperature regulation, and mood. High-dose biotin can interfere—hold if advised.

  • Vitamin D (25-OH): bone and muscle function; low in indoor/winter training.

  • Vitamin B12 & Folate: red cell production, nerve health.

  • Magnesium (± RBC Mg) & Phosphorus: muscle function, cramping; sweat loss matters.

  • Creatine Kinase (CK): skeletal muscle breakdown; draw on a rest day for clearer baselines.

  • hs-CRP (high-sensitivity C-reactive protein): low-grade inflammation; trend over time, don’t overreact to single spikes.

  • Urine Albumin-Creatinine (as indicated): early kidney stress signal in high-risk settings (heat, ultra-endurance).

Quick View: Panels & Uses

Group Why it matters Notes
CBC + Iron Studies Oxygen delivery; iron stores Add ferritin; avoid testing during acute illness
CMP + Electrolytes Hydration, kidney/liver context Schedule after an easy/rest day
Lipids + A1c/Glucose Long-term heart & fuel status Consider ApoB and Lp(a) for family risk
Thyroid (TSH ± FT4/T3) Energy, thermoregulation Check biotin interference guidance
Vitamin D, B12, Folate Bone, muscle, nerve support Season, sun, and diet influence levels
CK + hs-CRP Muscle load & inflammation Test on rest days; trend values

How the Testing Process Works

  1. Pick your starting set: most begin with CBC, CMP, Lipids, A1c or Fasting Glucose, plus Ferritin/Iron and Vitamin D.

  2. Add goal-based tests: TSHCKhs-CRPMagnesiumB12/Folate; consider ApoB/Lp(a) for family or personal risk.

  3. Time your draw: aim for a rest or easy day (24–48 hours after hard training); follow any fasting instructions on your order.

  4. Get results securely: most post within a few days.

  5. Plan next steps: review with your clinician or sports RD to refine nutrition, recovery, and follow-up.

Interpreting Results (General Guidance)

  • Trends beat single values: compare to your personal baseline and training log.

  • Account for timing: intense work can raise CK and liver enzymes and shift electrolytes and hematocrit.

  • Ferritin with context: pair with CBC and hs-CRP; ferritin may appear “normal” despite low stores during inflammation.

  • Out-of-range findings need clinician review—avoid self-treating with high-dose supplements.

Choosing Panels vs. Individual Tests

  • General training baseline: CBC • Ferritin/Iron Panel • CMP/Electrolytes • Lipid Panel • A1c or Fasting Glucose • Vitamin D • TSH

  • Recovery check (in-season): CK • hs-CRP • CMP/Electrolytes • Ferritin (if symptoms)

  • Strength/Power emphasis: CMP/Electrolytes • CK • Vitamin D • Magnesium • Lipids

  • Women’s health / REDs focus: CBC • Ferritin/Iron • Vitamin D • B12/Folate • TSH • CMP; discuss cycle timing with your clinician

  • Altitude or heat training: CBC/hemoglobin trend • CMP/Electrolytes • Ferritin/Iron • CK on rest days

FAQs

Do I need to fast?
Follow your order instructions. Fasting is common for lipids and glucose/insulin.

When should I schedule the blood draw?
On a rest day or at least 24–48 hours after a hard session to avoid CK and enzyme spikes.

Can supplements affect results?
Yes. Biotin can interfere with some thyroid assays; high-dose iron or vitamin D skews levels. Follow any holds listed on your order.

Are these anti-doping tests?
No. These labs support health and performance; anti-doping testing is handled by sport governing bodies.

How often should I repeat labs?
Common checkpoints are pre-seasonmid-season, and post-season, or after illness/injury. Your clinician may tailor timing to your training load and prior results.

Should I test hormones?
Hormone testing (e.g., testosterone, estradiol) is case-by-case. Discuss goals, symptoms, and timing with your clinician.

The Cardio IQ™ Diabetes and ASCVD Risk Panel with Scores measures advanced cardiovascular and metabolic markers to evaluate risk for atherosclerotic cardiovascular disease and type 2 diabetes. This panel includes lipid analysis, glucose-related biomarkers, and inflammation indicators, helping assess cardiometabolic health. Results provide clinicians with detailed scoring to identify patterns that may influence prevention and long-term disease management.


The Aldolase Test measures levels of aldolase, an enzyme involved in breaking down glucose for energy. Elevated levels may indicate muscle damage, muscular dystrophy, polymyositis, dermatomyositis, or certain liver diseases. Doctors use this blood test to help diagnose and monitor muscle disorders, evaluate unexplained weakness, and track treatment response. It is often ordered alongside CK and other enzyme tests for a complete evaluation of muscle health.

More than one-fourth of the world's population is unfit. This 25% of people aren't physically fit enough to be considered healthy.

But how can we tell if we're a part of that population? How do we measure our fitness level, and do we need to keep track of things like muscular endurance and body mass index (BMI)?

If you're asking any of these questions, you need a fitness health assessment. Fitness tests can help you and your healthcare providers understand what level of fitness you're at. With this information, you can plan to improve your fitness and lower your health risk.

To learn more about fitness lab tests and fitness in general, keep reading.

What Is a Fitness Health Assessment?

A fitness health assessment includes various exercises and tests that help evaluate your current level of health. To cover different kinds of health, it's important to assess different areas of the body and different abilities.

A fitness health assessment will include many different stages. Here are some examples:

  • General health evaluation
  • Body composition measurements
  • Cardiovascular endurance testing
  • Muscular endurance testing
  • Flexibility testing
  • Fitness lab tests

Each one of these categories is essential in determining the condition of your health. So, it's important not to skip any areas.

Since it's the least physical part of the evaluation, many people skip blood testing. It may not seem like an indicator of endurance or strength, but it still allows you and your healthcare team to determine how well the insides of your body are doing.

It's important to note that - just because you work out and/or eat right - doesn't mean that you're healthy on the inside. This is why we need to get a good look at the whole picture before your healthcare provider can truly say whether or not you fall within normal limits for your age.

Benefits of Getting a Fitness Health Assessment

The results of your fitness health assessment can tell you and your healthcare providers a lot about your health inside and out.

First, it gives your healthcare team a baseline. By knowing where your health levels and physical capacities are now, you and your healthcare provider can make better decisions about your health in the future.

For example, your healthcare provider may note some hypertension and high blood glucose during your exam. With this information, they now understand what your future goals need to focus on. Even better, they know how to help you improve from these numbers.

Next, a health assessment can be great for people already struggling with chronic illness or those starting to develop signs of something more serious. For these individuals, fitness tests can act as an incentive.

Fitness health assessments are concrete, and they provide exact numbers. From this objective data, patients can begin bettering themselves and improving their overall health. Seeing those numbers improve acts as a sort of incentive for these individuals.

Lastly, we should highlight the importance of fitness tests in training. Whether you're an athlete who's in conditioning or someone who likes going to the gym with their personal trainer, fitness tests can make it easy to set goals. Your trainer can test your current physical condition and help you figure out what your future goals are.

Overall, fitness health assessments are good for anyone and everyone. Even if you're not an athlete, fitness tests can help better your health overall and keep you more mindful about your body's condition.

What Are the Signs and Symptoms of Poor Fitness?

Since your fitness level has to do with the condition of your entire body, the signs and symptoms of being unfit are plentiful. Also, these signs and symptoms exist all over the body.

Here are some examples of the most common signs and symptoms of poor fitness:

  • Labored breathing
  • Shortness of breath after light activities
  • Mood swings
  • Weak or aching muscles after minimal activity
  • Insomnia or other sleeping problems
  • The development of health-related chronic diseases

This last sign is worth talking about. Notice how we're referring to health-related chronic diseases rather than all of them.

It's important to note that some people are predisposed to form these kinds of diseases due to genetic or environmental factors. So, we're not including congenital diseases or genetic predispositions here.

Rather, we're talking about some of the most notable chronic illnesses that have formed in individuals because of their eating habits, exercise habits, and other lifestyle choices. This could include hypertension, type II diabetes, coronary artery disease, and the like. Although these conditions have a genetic component, they can be exacerbated by poor diet and activity choices.

When in doubt, talk to your healthcare provider about your health and your goals.

How Is Fitness Monitored With Lab Tests?

Before wrapping up, we should talk about fitness lab tests. As we said, this is the most underrated part of the fitness health assessment. However, it can tell you the most about your actual health.

Just because someone isn't obese doesn't mean that they're healthy on the inside. Likewise, just because someone is obese doesn't mean they're unhealthy.

Since you cannot determine someone's health by looking at them, you should get lab testing. Here are some common tests that healthcare providers order to evaluate fitness level and health risk:

Fitness lab tests will include all of these basic tests, along with several others. This gives you a bigger picture of your fitness levels than you'll see from recorded training sessions.
