Real active recovery — what works and what doesn't


The recovery world is full of marketing-heavy products and thin evidence. Cryotherapy. Compression. USD 2000 saunas. Recovery socks. "Anti-inflammatory" supplements. Here I sort what the literature supports, what's well-marketed placebo, and what's straight-up counterproductive.


The honest hierarchy (highest to lowest ROI)


### 1. Sleep — the ONLY non-negotiable


If you sleep well, everything else matters little. If you don't sleep, nothing else works.


  • 7-9 hours/night in continuous block, not fragmented.
  • Deep sleep is where GH (growth hormone) is released and muscle microfractures repair.
  • Mah et al 2011: basketball players who slept 10h/night improved 9% free throws and 5% sprints — without touching training.
  • For amateur athletes: working to hit 9h+ one night/week is better than any recovery gadget.

    • What helps sleep: total darkness, cool (64-68°F), no screens 30 min before, zero caffeine after 2 PM, magnesium before bed if needed.


    ### 2. Food in the post-session window


    30-60 min after a session >90 min: 1-1.2 g CHO/kg + 20-30 g protein. Critical period where glycogen synthesis and muscle repair peak.


  • Concrete example (155 lb athlete): 80g oats + 1 banana + 30g whey + 1 tbsp honey.
  • After 60 min, the window closes (doesn't fully close, but absorption speed drops 30-50%).

    • ### 3. Easy walking (15-30 min) post-hard session


    After a Z4+ session or long run, 15-30 min walk in the evening or next day:

  • Improves circulation without adding load.
  • Reduces DOMS (delayed onset muscle soreness) per Andersson 2008.
  • Zero cost, zero equipment.

    • ### 4. Hydration + electrolytes


    17-25 fl oz of water with sodium (300-500 mg) in the 2h post-session. Restores plasma volume.


    Pro tip: weigh before and after the workout. For every kg lost, drink 1.2-1.5 L (not exactly 1 L — the body pees part).


    The "it depends" — works in some cases


    ### 5. Sauna 80-90°C (176-194°F), 15-20 min, 2-4 times/week


    Evidence:

  • Lifts plasma volume 5-15% (Scoon 2007) — useful for heat acclimation.
  • Reduces mild systemic inflammation.
  • Improves cardiovascular recovery post-session.

    • When not to: after a very hard session, if still dehydrated, or with cardiovascular issues.


    ### 6. Ice baths (50-59°F, 10-15 min)


    Works for: acute recovery between back-to-back sessions (e.g. UTMB with multiple days). Reduces inflammation and DOMS short-term.


    Does NOT work for: gaining training adaptation. Cold immersion post-strength session inhibits muscle protein synthesis (Roberts 2015). If you train strength and want to gain mass, no ice bath after.


    ### 7. Compression (socks, sleeves)


    Works: light perceived DOMS relief, improves recovery sensation.

    Does not work: doesn't improve performance or measurable recovery speed objectively.

    Verdict: reasonable placebo. If it makes you feel better, OK. Not hard science.


    ### 8. Foam roller / massage


    Works: improves acute range of motion (15-30 min post). Reduces perceived DOMS.

    Does not work: doesn't accelerate real muscle recovery or "release lactate" (full myth).

    When to use: before quality session (improve mobility) more than after.


    What does NOT work (and is heavily sold)


    ### Anti-inflammatory supplements (turmeric, mega-dose omega-3)


    For the amateur athlete with a reasonable diet, minimal to zero impact. They make sense for diagnosed chronic inflammation profiles. Not for "normal post-session recovery."


    ### Compression socks during the session


    Doesn't improve performance. Zero evidence. Just psychology.


    ### Full-body cryotherapy (-110°C, 3 min)


    Same effect as a home ice bath but 100x more expensive. Zero comparative advantage.


    ### "Detox" / "body cleansing" supplements


    Your liver and kidneys detox on their own. No products needed.


    ### Static stretching before running


    Reduces performance in sprints and strength work (Behm 2016). Yes useful end of day as mobility — not before.


    What you can do at home with zero cost


    1. Sleep 8h (free, max ROI).

    2. Walk 20 min after work (free, high ROI).

    3. Eat protein + carbs post-session (cost of your normal food).

    4. Hydrate well (tap water + a pinch of salt).

    5. Foam roller 10 min/day before quality (~USD 20 once).

    6. Dry sauna 1-2x/week if you have club or gym access (~USD 50/mo).


    In Vetta


    The engine marks recovery days explicitly. It's not "rest for rest's sake" — it's the day where muscle repairs and gets stronger. Simple rule: TSB > +5 = race-ready, TSB between -10 and +5 = productive, TSB < -15 = force recovery.


    [Connect Strava](/signup) and the engine shows your TSB live + suggestions for when to back off.
