Chilly plunges, high-street cryotherapy chambers and the much-publicised Wim Hof technique have made freezing restoration therapies a sizzling subject. Can brief, sharp exposures to very chilly temperatures actually profit cyclists, or do the associated dangers – to not point out to the discomfort – outweigh any potential beneficial properties?
“We use chilly water immersion through the summer season Excursions and its chief advantages are physique cooling within the warmth and quicker muscle restoration after train,” Loïc Cuigniez, medic with staff Lotto-Dstny tells Biking Weekly. “The chilly baths induce an anti-inflammatory response, lowering secondary muscle harm and enhancing muscle restoration. Since warmth additionally provides additional stress to the guts, the earlier the riders settle down, the higher they recuperate.”
Chilly remedy is available in a few codecs: Firstly, entire physique cryotherapy (WBC), publicity to extraordinarily low temperatures in specialised chambers or with units delivering chilly air to particular areas of the physique. Secondly, ice baths and cold-water immersion (CWI), submerging the physique in chilly water. Whereas each purpose to attain comparable physiological results, cryotherapy presents the benefit of exact temperature management and shorter publicity instances.
Complete-body cryotherapy includes immersing your entire physique in sub-zero temperatures for a short interval, sometimes two to 4 minutes. This makes it extra handy for elite athletes with busy schedules. The Leicester Metropolis soccer staff that received the Premier League in 2016 used a cryotherapy chamber to hurry up participant restoration throughout a interval of jam-packed fixtures. However for the reason that ‘iceman’ Wim Hof cometh, there was a heightened curiosity within the purported advantages of straightforward ice baths.
Proponents of ice baths consider that their advantages prolong past merely cooling down and ramping up restoration. Sceptics, however, warn that taking such chilly plunges to an excessive could possibly be at finest a waste of time and at worst doubtlessly life-threatening.
The advantages

■ Throughout or straight after the ice tub, they’ve a restoration shake with carbs and proteins, equipped by Precision Gasoline and Hydration.
■ We additionally promote energetic restoration periods post-race with a 15-minute straightforward spin on the rollers.
■ Through the bus journey to the resort, some riders put on compression clothes (Normatec) earlier than the soigneurs do their therapeutic massage.
The entire above assist to scale back perceived exertion the following day, making riders extra resilient and bodily and mentally able to compete once more.
Cryotherapy has been proven to be an efficient post-exercise restoration technique, with analysis demonstrating lowered delayed onset muscle soreness (DOMS),” explains Dr Laura Wilson, a senior lecturer in train physiology and diet on the London Sport Institute based mostly at Middlesex College. She has carried out research with endurance athletes to measure the impression of cryo chambers and cold-water immersion on efficiency and restoration. “It’s additionally led to lowered scores of perceived exertion (RPE) skilled in subsequent train bouts following cooling.”
Whereas cryotherapy chambers provide essentially the most intense, hi-tech chillout, they’re not low-cost and much from cell. An ice tub could be simply as efficient, says Wilson. “Chilly water immersion stays the commonest cryotherapy modality in observe. Different strategies together with ice pack utility or entire physique cryotherapy utilizing cooling chambers have all demonstrated comparable outcomes.”

For Lotto-Dstny riders, there’s no want for a cryo chamber. “We simply have a conveyable tub on the staff bus,” says Cuigeniez. “We fill it on the end line with chilly water of 10-15°C and riders go in with their legs immersed for 5 minutes.” At UAE Workforce Emirates, two-time Tour de France winner Tadej Pogačar is one other professional who values a post-race fast dip in a paddling pool filled with ice. The Slovenian is, in accordance with his medical director Adriano Rotunno, one in all a quantity to take an ice tub for its psychological advantages as a lot because the bodily ones.
“It’s not supposed for restoration or efficiency however simply to permit the rider to really feel higher after the stage,” Rotunno informed Dutch newspaper Het Laatste Nieuws after Pogačar took a dip through the first stage of the 2023 Tour in Bilbao. “We don’t do extended submersions, as a result of the longer the submersion, the extra deleterious it’s to efficiency,” the physician defined. “It’s purely to chill down physique temperature – an acute submersion, we go out and in for lower than a minute at a wholesome temperature.” Pogačar’s team-mate Adam Yates has additionally taken to cooling down within the staff’s ice-filled inflatable paddling pool after a stage – maybe no shock from a rider who partially blamed the warmth of the French summer season for the time he misplaced on the Tour in 2018.
Resilience enhance
It’s the reported ‘really feel higher’ advantages of cold-water immersion which have piqued the curiosity of Tom Haines, sport and train psychologist and coach on the College of Nottingham. “I’m very a lot of the college that claims should you really feel you’re getting beneficial properties from it, then comfortable days, crack on with it,” says Haines. “There’s additionally the often-overlooked profit that comes from placing your self by way of one thing disagreeable like an ice tub each few days.” He’s referring right here to psychological forbearance. “You’ll discover that your gruelling coaching hill journey within the freezing rain is marginally simpler to handle mentally should you can inform your self, ‘that is nothing in comparison with that ice tub yesterday’.”
Backing up this idea is a 2020 examine revealed within the Worldwide Journal of Environmental Analysis and Public Well being that discovered that CWI can have a optimistic impact on the endocrine system and the psyche, together with lowering the signs of melancholy.
Chilly begins
Chilly water retains me sizzling on type
Newbie rider Michael Kanizay, 56, from Melbourne, Australia, is a agency believer in chilly water immersion: “I don’t really feel as sturdy on the bike if I journey with out first doing chilly water immersion (CWI). I began every day CWI again in March of 2019 out of curiosity. I’d heard Wim Hof interviewed on a podcast and I already used the yogic respiration methods Wim urged to beat chilly sensations on the bike and whereas operating. “As a aggressive bicycle owner in C grade/Cat 3 and Masters B grade/ Cat 2, using six days per week, CWI has turn out to be a cornerstone of my routine. I take advantage of a salt water chlorinated pool at house, immersing myself six instances, specializing in respiration for about six seconds every time. Initially, with water round 20°C, it was refreshing, however as winter units in, temperatures drop to 10°C. Even when away from house, I substitute with a 90-second chilly bathe. “Bodily, CWI invigorates me, enhancing my alertness and vitality. Skipping it leaves me missing in vitality. Decreasing my core physique temperature doubtlessly will increase efficiency capability, particularly throughout intense indoor rides when overheating hampers efficiency. My improved tolerance to chilly situations is obvious throughout group rides in colder months. “There’s a buzz related to CWI, which I later discovered is because of dopamine launch. Having the ability to do one thing that takes me out of my consolation zone may be very empowering and I really feel like I take a component of that with me into the day.”
The usefulness of cold-water immersion isn’t restricted to post-ride cooling, in accordance with Haines. “Ice baths impact your sympathetic nervous system, instantly ramping up your physique’s activation hormones,” he says. “The mind thinks ‘oh sh**t, that is hassle’ so that you get that hit of adrenaline, noradrenaline, cortisol and endorphins. There are these chemical compounds dashing round your physique, making you’re feeling invincible.”
It’s a degree echoed by Jorge Lopes Storniolo, physiologist within the division of pathophysiology and transplantation on the College of Milan. “Earlier than train, intense chilly publicity might positively have an effect on the physique, from the autonomic nervous system viewpoint,” Storniolo explains. His Milan analysis staff carried out a examine amongst 28 cyclists, monitoring their coronary heart exercise earlier than, throughout, and after train, to measure how cryotherapy affected efficiency. WBC was discovered to extend time to exhaustion by round 12-14% and shortened coronary heart?charge restoration instances.
“We discovered that WBC improves the general means to provide mechanical energy,” says Storniolo. “The time to exert maximal work will increase proportionately to a persistent discount of sympathetic tone [baseline stimulation of the sympathetic nervous system] after the only WBC session.” Although a lot of the analysis surrounding cryotherapy focuses on post-exercise restoration methods, its potential for manipulating core temperatures and enhancing train efficiency is basically untapped.
“Throughout train, core temperature will increase on account of warmth manufacturing ensuing from muscular contractions,” says Laura Wilson, “and this will increase ‘thermal pressure’ which negatively impacts endurance efficiency. However cryotherapy can be utilized earlier than train to scale back core temperature, thereby permitting cyclists to train for longer, or tolerate increased environmental temperatures for longer.”
The ‘Scottish bathe’
“Cryotherapy could be an efficient intervention for professional and novice cyclists alike,” insists Wilson, who recommends making use of it as quickly as fairly doable after a race. “The processes that result in exercise-induced muscle harm (EIMD) and the resultant signs – soreness and swelling, and so forth – are initiated as quickly as train begins, so the sooner you’ll be able to apply cryotherapy, the simpler it’s more likely to be.”
Popping right into a cryotherapy chamber and even having a tin tub filled with ice on the finish of Sunday lengthy journey isn’t a straightforward choice for many of us. However a ‘Scottish Bathe’ is. “Merely turning the bathe to chilly for a minute earlier than getting out is a gradual means of acclimatising to chilly water immersion,” suggests Tom Haines. The deserves of alternating between cold and hot showers to induce a number of the advantages of cold-water immersion are backed up by analysis revealed within the Journal of Bodily Remedy in Sport. “Round 10-Quarter-hour at 10-15°C is right,” says Wilson, “and this temperature is probably going achievable from the chilly water faucet at house.”
Potential pitfalls
Whereas cryo chambers are showing on the high-street and ice plunge tanks turn out to be the most recent must-have house restoration accent, there are security considerations amongst some specialists. Speedy immersion in icy water poses dangers together with hypothermia, frostbite, and shock. Taking an ice-cold plunge has been linked to at the least one fatality within the US, prompting Professor Mike Tipton from the acute environments laboratory on the College of Portsmouth to challenge a warning. “I wouldn’t do something that places such an quantity of stress on the physique with out having a check-up that I used to be match and wholesome sufficient to do it,” he says.

The Wim Hof technique’s emphasis on holding one’s breath and enduring excessive chilly publicity has are available for scrutiny amongst fears that the method may deprive their mind of oxygen, growing the chance of fainting or hypoxic mind harm. Prof Tipton has reviewed a lot of the educational analysis obtainable to this point and pours chilly water on lots of the purported advantages of cold-water immersion for athletes. “The vast majority of present analysis is descriptive in nature and subsequently contributes a restricted quantity to the understanding of the potential mechanisms underpinning the consequences of particular restoration methods,” he tells CW. “There are a lot of areas that future mechanistic analysis ought to tackle, with essentially the most pertinent subjects being the consequences of water temperature, hydrostatic strain and the applying following completely different train varieties.”
In line with Tipton, chances are you’ll be higher off doing an energetic warm-down on the rollers than taking a chilly dip. Additional examination of analysis (Peake et al. 2017) backs this up, suggesting that “CWI is not any simpler than energetic restoration for lowering irritation or mobile stress on this single-bout train mannequin.” With reference to irritation, Tipton says: “If CWI reduces the inflammatory response to exercise-induced trauma, it might in truth be counter-productive.” Tom Haines shares this view: “Utilizing ice baths for fast restoration after a sizzling race is okay, however dampening irritation throughout restoration is one thing I’m sceptical about. You don’t need to scale back irritation quickly as a result of it’s a part of the method that helps us absolutely recuperate, restore and construct again stronger. Why would we need to cease that?”
Elite biking groups aren’t about to ditch the chilly tub or post-ride ‘Scottish bathe’ simply but, although. As a method of cooling the physique down and inducing some notion of enhanced restoration, it stays a part of the professionals’ armoury. As Haines factors out, if dipping your aching legs in a chilly tub isn’t doing you any hurt and feels good, then why not do it. However in the case of organising a Lebron James ice tub within the backyard, one of the best recommendation appear to be: don’t take a surprising ice plunge alone, don’t do it with out your GP’s say-so and don’t do it on the sacrifice of well-established and absolutely examined restoration strategies reminiscent of warm-down train, the appropriate diet and a good night time’s sleep.
