High-Intensity / VO2 Max Recovery
High-intensity sessions place heavy demands on muscles, the nervous system, and energy stores, so recovery needs careful timing across the season. During Base, recovery focuses on learning to tolerate intensity while preserving adaptation signals. In the Build phase, it manages accumulated sympathetic stress and hormonal load. As you approach Peak, the emphasis moves to central nervous system restoration and sleep quality. In Transition, recovery becomes restorative and unstructured. This protocol shows you how to recover without losing the adaptations that make you faster.
Athlete Guide
-
Objective: Support mitochondrial biogenesis, neuromuscular adaptation, and tolerance to higher aerobic strain.
0–2 hr post-session:Rehydrate promptly, with electrolytes as required (eg. PF&H 1500 mg/L).
Eat within 30–45 min: 1.2 g/kg carbohydrate + 0.3 g/kg protein.
2–24 hr:
Eat balanced meals every 3–4 hr; prioritise complex carbohydrates and lean protein.
Light stretching or yoga in the evening; 8–9 hr sleep.
-
Objective: Maintain high-intensity adaptations while managing sympathetic stress.
0–2 hr:Refuel as above; avoid ice baths or aggressive cooling.
Gentle mobility and breathing control to promote recovery.
2–24 hr:
Distribute protein evenly (0.25–0.3 g/kg every 3–4 hr).
Hydrate steadily; consider tart cherry or beetroot foods (not concentrates) for natural polyphenols.
Mindfulness or relaxation before bed.
-
Objective: Preserve performance readiness and CNS recovery while preventing maladaptation.
0–2 hr:Carbohydrate-protein refuelling within 30 min; avoid high-fat meals.
5–10 min gentle cooldown, deep breathing, or meditation.
2–24 hr:
Maintain hydration and structured relaxation.
Avoid stimulants (high caffeine, alcohol).
-
Objective: Restore full autonomic and hormonal balance.
0–2 hr:Normal balanced meal; no need for precision fuelling.
2–24 hr:
Rest or light activity (walk, yoga, swim).
Spend time outdoors; aim for natural light exposure.
Coach Guide
-
High-intensity work at this stage promotes mitochondrial biogenesis and improved VO₂ kinetics (Gibala et al., 2012). Adequate carbohydrate intake post-session supports glycogen restoration and training quality without fully suppressing AMPK–PGC-1α signalling (Bartlett et al., 2012). Encourage natural antioxidant sources rather than supplementation to allow redox-mediated adaptation.
Coaching cue: Educate athletes that recovery nutrition supports consistency, not indulgence; focus on rhythm rather than rigidity. -
During block loading, sympathetic activation and elevated cortisol are prominent (Meeusen et al., 2013). Recovery should restore parasympathetic dominance through breathwork, mindfulness, or low-intensity movement to aid this (Stanley et al., 2013). Cold-water immersion may blunt angiogenic and mitochondrial signals and should be reserved for competition or heat conditions (Roberts et al., 2015).
Coaching cue: Reinforce that feeling tired is expected; emphasise recovery as a skill rather than a reaction. -
Focus on central nervous system recovery and hormonal equilibrium. High-intensity training can transiently suppress testosterone and thyroid activity; prioritising sleep and carbohydrate sufficiency supports restoration (Halson, 2014).
Coaching cue: Help athletes distinguish “training fatigue” from early maladaptation; maintain open dialogue on mood, sleep, and drive. -
Autonomic and endocrine systems require recalibration. Encourage unstructured movement, exposure to daylight, and psychological detachment (Kellmann et al., 2018).
Coaching cue: Facilitate reflective debriefs; link physiological recovery with mental reset and intrinsic motivation.
