Übungen bei Sarkoidose — ermüdungsabgestuft, Herz-Screening ZUERST, Vitamin-D-Paradox

ATS/ERS/WASOG 1999 statement + 2024 ATS update + ACCESS study framework. Sarcoidosis is a granulomatous multisystem disease — pulmonary involvement affects ~90% of patients (hilar adenopathy, parenchymal disease at various stages); but the systemic reach extends to cardiac (LBBB + ventricular arrhythmia + sudden death risk in cardiac sarcoidosis), neuro (cranial neuropathy + aseptic meningitis), ocular (uveitis), cutaneous (erythema nodosum, lupus pernio), hepatic, and renal (nephrocalcinosis). Fatigue is the dominant symptom — the Sarcoidosis Fatigue Assessment Scale exists precisely because fatigue defines disability for many patients more than dyspnea does. Marcellis 2013 + Naz 2018 RCTs established that progressive aerobic + light strength training reduces fatigue and improves 6-minute walk distance without triggering flares. CRITICAL: cardiac sarcoidosis screening (Holter + cardiac MRI per consensus) BEFORE aerobic prescription — untreated cardiac sarc has sudden death risk that an exercise plan must respect. Steroid-induced osteoporosis is common from chronic prednisone. The vitamin D PARADOX in sarcoidosis is the single most important nutrition lever — sarcoid granulomas express 1α-hydroxylase that converts 25-OH-D → 1,25-OH-D without normal feedback, risking hypercalcemia (Burke 2015 + Kavathia 2010). AVOID megadose vitamin D supplementation; CONFIRM 25(OH)D + 1,25(OH)D + calcium + PTH with rheumatology/pulmonology BEFORE any dose.

Volya's catalogue carries the foundation moves: supported-glute-bridge for posterior chain low-intensity work, wall-push-up for scaled upper-body strength, scapular-retraction for posture, cat-cow for spinal mobility + parasympathetic, supine-knee-to-chest for low-back release, diaphragmatic-breathing for parasympathetic + chest-wall mobility + pulmonary mucus mobility, pursed-lip-breathing for dyspnea management (sarcoidosis interstitial process), standing-march for managed cardio (after cardiac screen), sit-to-stand for functional + bone-loading (steroid osteoporosis). The AI coach also knows the nutrition side — Mediterranean anti-inflammatory backbone (Nardi 2019 + Sweis 2020), vitamin D PARADOX confirm labs FIRST before any supplementation, calcium dietary moderate AVOID supplements without checking serum + 24h urine calcium, omega-3 1-3 g/day EPA+DHA, protein 1.2-1.4 g/kg/day for steroid lean-mass loss, AVOID oxalates moderate if hypercalciuria, cardiac sarc low-sodium <2 g/day, AVOID alcohol excess with methotrexate hepatotoxicity. CRITICAL: Foundation for Sarcoidosis Research (FSR) + ATS + rheumatology + pulmonology + cardiology if cardiac sarc + neurology if neuro-sarc + ophthalmology if uveitis + nephrology if renal + endocrinology. This is NEVER a replacement for pulmonology + multispecialty care.
