Hyperbaric Oxygen Therapy — Single Session (60 min)

Hyperbaric oxygen therapy (HBO) at Kyslík Hradec Králové delivers a 60-minute session inside a hard-shell mild hyperbaric capsule within the Extrifit Gym complex — the first and only publicly accessible HBO service in Hradec Králové. During the session the capsule is pressurised to approximately 1.3–1.5 ATA, increasing the concentration of oxygen dissolved in blood plasma beyond what haemoglobin alone can carry. This dissolved oxygen reaches tissues with restricted circulation, may reduce inflammation, and can support faster recovery from physical exertion. The setup is designed to fit naturally into an active lifestyle: book a session before or after your gym training, or on a rest day for systemic recovery. The session is non-invasive and performed fully clothed inside a comfortable reclining capsule. First-time users receive a briefing on ear pressure equalisation before entering. At 2 100 Kč per session, it is competitively priced within the Czech mild hyperbaric market and conveniently co-located with Extrifit's full fitness and wellness facilities.

Hyperbaric oxygen therapy (HBO) works on Henry's Law: under increased atmospheric pressure, more gas dissolves into liquid. Inside the pressurised capsule at Kyslík Hradec Králové, the air pressure rises to roughly 1.3–1.5 ATA — between 30 % and 50 % above sea-level atmospheric pressure. At this pressure, the oxygen concentration in the lungs increases proportionally, and a measurably higher volume of oxygen dissolves directly into blood plasma, lymph and interstitial fluid. This dissolved oxygen is not bound to haemoglobin and therefore can diffuse into areas that haemoglobin-delivered oxygen struggles to reach: ischaemic or poorly perfused tissue, inflamed muscle fibres, post-training micro-tears and skin layers distant from major capillary beds. The Extrifit Gym setting is particularly suited to athletes and physically active individuals. Post-workout HBO sessions may support faster clearance of inflammatory mediators, reduced delayed-onset muscle soreness (DOMS) and accelerated glycogen replenishment in muscle tissue. Pre-competition or pre-training sessions are also used by some athletes for priming tissue oxygenation. Beyond athletic recovery, regular mild HBO sessions have been associated — in observational data — with improved cognitive clarity, reduced fatigue, better sleep quality and a general increase in subjective energy. These effects are thought to be mediated by improved mitochondrial efficiency as cells in oxygen-depleted states receive an influx of dissolved O₂. The session at Extrifit Hradec Králové unfolds in three phases. First, pressurisation: you enter the capsule, the staff member seals it, and the internal pressure builds gradually over approximately 8–12 minutes. During this phase you will notice a sensation similar to descent on an aircraft — a mild pressure in the ears that you relieve by swallowing, yawning or performing a gentle Valsalva manoeuvre. The wellness team briefs all first-time users on this technique before they enter. Second, the plateau phase: the capsule holds at the target pressure for approximately 40 minutes. You can rest, read on a device, listen to music through earphones, or simply close your eyes. Third, depressurisation: pressure returns to ambient over about 8–10 minutes, completing the full 60-minute cycle. The capsule at Kyslík is a hard-shell unit — rigid construction that maintains stable pressure throughout and allows a more consistent experience than soft-shell alternatives. It is fully equipped with internal lighting, a ventilation circuit to keep temperature comfortable and a communication channel with the operator outside. Who benefits most: athletes in a training or competition block, individuals recovering from sports injuries or post-surgical tissue healing, people managing persistent fatigue, those experiencing post-viral energy deficit or cognitive slowness, and anyone seeking a periodic wellness top-up that works at a systemic rather than surface level. The gym environment means most clients are already health-oriented and integrate HBO as one layer of a broader recovery or wellness stack. Preparation is simple: wear comfortable, loose-fitting clothing, remove metallic jewellery or accessories, avoid a heavy meal in the two hours before the session and arrive five to ten minutes early for your first visit to complete a brief intake form. Contraindications include active fever, acute ear or sinus infection, recent ear surgery, untreated pneumothorax, active malignancy, uncontrolled hypertension and severe claustrophobia. The staff at reception can help clarify any concerns before you book.
