Understanding the Role of Cryotherapy in Recovery: Insights from Recent Research

Cold Therapy • 3 min read • Based on research by James R. Broatch, Mathilde Poignard, Christophe Hausswirth, David J. Bishop, François Bieuzen (2019)

Have you ever stepped into a cold plunge after an intense workout, hoping to feel rejuvenated and ready for your next challenge? The allure of cold therapy, particularly whole-body cryotherapy, has captivated athletes and wellness enthusiasts alike. The promise of enhanced recovery and improved performance often drives people to seek out these icy treatments.

However, recent research sheds light on the effectiveness of cryotherapy in enhancing training adaptations, particularly following high-intensity interval training (HIIT). In a study conducted by Broatch et al. (2019), scientists sought to determine whether post-exercise cryotherapy truly provides the benefits it claims. The findings may reshape how we approach recovery protocols in our wellness routines.

What the Study Revealed

The study involved 22 well-trained male participants who engaged in four weeks of high-intensity cycling workouts. After each session, half of the group underwent three minutes of whole-body cryotherapy, while the other half rested passively. The researchers measured a range of performance metrics, including peak oxygen uptake (VO2peak) and peak power output, before and after the training period.

The results were surprising. Regular post-exercise cryotherapy did not lead to significant improvements in aerobic adaptations or performance metrics compared to the control group. In essence, the cold exposure did not enhance the benefits typically associated with high-intensity training.

Understanding the Mechanism

Whole-body cryotherapy involves short exposures to extremely cold temperatures, typically around -110°C to -160°C. The theory behind its use in recovery is that this intense cold can reduce inflammation, alleviate pain, and promote faster recovery. However, the study found that these expected benefits did not translate into enhanced aerobic performance or hormonal responses.

More specifically, the researchers observed no significant differences in hormonal responses such as adrenaline, noradrenaline, and cortisol levels between the cryotherapy and control groups. Additionally, sleep patterns remained unchanged. This suggests that while cryotherapy may feel refreshing, it may not yield the physiological adaptations that many seek through rigorous training.

Practical Implications for Your Recovery Protocol

So, what does this mean for those of us who incorporate cryotherapy into our recovery rituals? While whole-body cryotherapy is often touted for its recovery benefits, this study indicates that it may not be the most effective strategy for enhancing endurance training adaptations. Athletes and trainers should consider these findings when planning their recovery protocols.

Instead of relying solely on cryotherapy, it may be beneficial to explore other recovery strategies that have demonstrated more significant effects on performance adaptation. This could include practices such as active recovery, proper nutrition, and sleep hygiene, which have been shown to support resilience and overall well-being.

Key Takeaways

Whole-body cryotherapy did not improve performance adaptations in endurance training, according to recent research.
Consider integrating other recovery strategies, such as nutrition and sleep hygiene, into your wellness routine for better results.

🧊 Wim's Wise Words

Whole-body cryotherapy does not augment adaptations to high-intensity

What This Paper Is Actually Saying

Here's what Broatch and colleagues set out to answer: if you add whole-body cryotherapy after every hard training session for four weeks, do you get better results than just training alone? The answer, with statistical confidence, is no. Both groups improved — because high-intensity interval training is extraordinarily effective at improving aerobic power and VO2 peak. The cryotherapy group just didn't improve any more than the group that sat and rested.

No difference in peak power. No difference in time-trial performance. No difference in hormonal markers — adrenaline, noradrenaline, cortisol all moved similarly between groups. Sleep quality, unchanged. Twenty-two well-trained men, four weeks, rigorous methodology. The signal is clear.

Where This Fits in the Larger Conversation

This paper exists in tension with some of the most compelling cold therapy research of the past decade. The same first author — Broatch — was involved in earlier work showing that cold water immersion could promote mitochondrial biogenesis during extended training periods. The hypothesis going into this study was reasonable: if immersion in cold water augments aerobic adaptation, perhaps whole-body cryotherapy — which produces comparable reductions in tissue and core temperatures — might do the same.

It didn't. And that gap matters. Cold water immersion and whole-body cryotherapy are not the same tool. Water extracts heat from the body roughly 25 times more efficiently than air, even air at -110 degrees Celsius. The physiological stimulus, despite the dramatic temperature difference, may simply not be equivalent. WBC is drier, faster, and — it turns out — less metabolically disruptive than full immersion.

The goal was never just to feel less sore. It was to get better. And this research draws a clean line between those two things.

Where Experts Agree and Disagree

There's genuine scientific agreement that cold therapy — in various forms — reduces perceived soreness and attenuates acute inflammation after exercise. That's well-documented. The disagreement is whether that's always a good thing. A growing body of research, including landmark work by Roberts and colleagues, has shown that regular cold water immersion after strength training can blunt muscle hypertrophy by interfering with the inflammatory signals that drive adaptation. The inflammation feels like the problem. But it's also the signal.

This paper adds a different nuance: WBC doesn't even reliably produce the recovery benefits that would justify its use during heavy training blocks. It's not that it helps recovery at the cost of adaptation. It's that the evidence for significant benefit is simply thin.

My Practical Recommendation

If you're in a hard training block — building aerobic capacity, chasing performance gains — whole-body cryotherapy after every session is probably not the tool you need. Save cold exposure for competition windows, travel recovery, or periods where you're managing accumulated fatigue rather than trying to drive new adaptation. Cold water immersion used strategically, not daily, appears to be the more evidence-backed choice.

The Surprising Connection

What strikes me most here is a subtle design insight the authors almost understate: both groups improved significantly. VO2 peak up five to eight percent in four weeks. Peak power up six percent. The training worked beautifully. The cryotherapy question turned out to be a footnote to a much cleaner story about what high-intensity interval training actually does to a well-trained body. Sometimes the most useful finding is the control condition — a reminder that the basics, done consistently and at the right intensity, are already extraordinarily effective.
