Sports Fitness & Athlete Health Check-Up

A specialised blood and clinical assessment panel designed for active individuals and competitive athletes who want to optimise performance, avoid overtraining, and ensure their body is recovering adequately. The Sports Fitness check-up at Medianna Clinic combines standard safety markers with performance-relevant parameters — iron studies, ferritin, magnesium, Vitamin D, creatine kinase, thyroid function, and haematological markers — providing a detailed picture of an athlete's physiological baseline and any gaps that may be limiting performance or increasing injury risk.

Athletes and frequent exercisers are not immune to nutritional deficiencies — in fact, high training loads increase demand for iron, magnesium, vitamin D, and B vitamins, while simultaneously increasing losses through sweat, inflammation, and oxygen turnover. Overtraining syndrome, sports anaemia, and chronic muscle damage are all identifiable through targeted blood markers, yet standard check-ups rarely include the parameters most relevant to athletic health. Medianna Clinic's Sports Fitness panel assembles the markers with the strongest evidence base for sports medicine in general practice: haematological markers — full blood count with red cell indices, reticulocytes if anaemia suspected, providing a baseline for oxygen-carrying capacity, iron studies — serum iron, TIBC, ferritin (the most sensitive marker of iron stores; ferritin below 30 µg/L impairs endurance performance even without frank anaemia), magnesium — low in high-output athletes; implicated in muscle cramps, impaired recovery, and sleep quality, vitamin D 25-OH — essential for muscle function, bone health, and immune regulation; deficiency is common in northern/central European athletes training indoors, creatine kinase (CK) — a marker of acute muscle damage; persistently elevated CK outside competition periods suggests insufficient recovery or overtraining, thyroid function (TSH, FT4) — subclinical hypothyroidism causes fatigue and weight gain that can masquerade as overtraining, and testosterone/cortisol ratio (optional add-on) — an established overtraining marker in competitive athletes. **Who benefits most:** Endurance athletes (runners, cyclists, triathletes), team sport players, gym-focused individuals, and anyone experiencing unexplained performance plateaus, persistent fatigue, or frequent illness. Also valuable before starting a new training block or returning from injury. **Session protocol:** Blood is drawn fasting. The physician review contextualises markers in relation to training load and performance goals — not just standard reference ranges, which are derived from sedentary populations and may misclassify athletic norms. **Preparation:** Fast 8–10 hours. Avoid intense training in the 48 hours before the appointment (CK elevation from acute training can confound results). Bring your training log or a summary of weekly training volume if available. **Aftercare:** Resume normal activity when comfortable. The physician will advise on any supplementation or lifestyle changes suggested by the results.
