Chilly plunges, high-street cryotherapy chambers and the much-publicised Wim Hof methodology have made freezing restoration therapies a sizzling matter. 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 positive factors?
“We use chilly water immersion in the course of the summer time 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, decreasing secondary muscle harm and enhancing muscle restoration. Since warmth additionally provides further stress to the center, the earlier the riders quiet down, the higher they recuperate.”
Chilly remedy is available in a few codecs: Firstly, complete 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 goal to realize related physiological results, cryotherapy provides the benefit of exact temperature management and shorter publicity occasions.
Entire-body cryotherapy includes immersing the whole physique in sub-zero temperatures for a quick interval, usually 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 because the ‘iceman’ Wim Hof cometh, there was a heightened curiosity within the purported advantages of easy ice baths.
Proponents of ice baths consider that their advantages lengthen past merely cooling down and ramping up restoration. Sceptics, alternatively, warn that taking such chilly plunges to an excessive might be at greatest a waste of time and at worst doubtlessly life-threatening.
The advantages

■ Throughout or immediately after the ice bathtub, they’ve a restoration shake with carbs and proteins, provided by Precision Gas and Hydration.
■ We additionally promote energetic restoration classes post-race with a 15-minute simple spin on the rollers.
■ Throughout the bus experience to the resort, some riders put on compression clothes (Normatec) earlier than the soigneurs do their therapeutic massage.
The entire above assist to cut 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 primarily based at Middlesex College. She has carried out research with endurance athletes to measure the influence of cryo chambers and cold-water immersion on efficiency and restoration. “It’s additionally led to lowered rankings of perceived exertion (RPE) skilled in subsequent train bouts following cooling.”
Whereas cryotherapy chambers provide probably the most intense, hi-tech chillout, they’re not low-cost and much from cellular. An ice bathtub may be simply as efficient, says Wilson. “Chilly water immersion stays the most typical cryotherapy modality in apply. Different strategies together with ice pack software or complete physique cryotherapy utilizing cooling chambers have all demonstrated related outcomes.”

For Lotto-Dstny riders, there’s no want for a cryo chamber. “We simply have a transportable bathtub 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 Staff 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 every of a quantity to take an ice bathtub for its psychological advantages as a lot because the bodily ones.
“It’s not meant for restoration or efficiency however simply to permit the rider to really feel higher after the stage,” Rotunno instructed Dutch newspaper Het Laatste Nieuws after Pogačar took a dip in the course of 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 time 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 when you really feel you’re getting positive factors from it, then completely happy days, crack on with it,” says Haines. “There’s additionally the often-overlooked profit that comes from placing your self by means of one thing disagreeable like an ice bathtub each few days.” He’s referring right here to psychological forbearance. “You’ll discover that your gruelling coaching hill experience within the freezing rain is marginally simpler to handle mentally when you can inform your self, ‘that is nothing in comparison with that ice bathtub 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 constructive impact on the endocrine system and the psyche, together with decreasing the signs of despair.
Chilly begins
Chilly water retains me sizzling on kind
Newbie rider Michael Kanizay, 56, from Melbourne, Australia, is a agency believer in chilly water immersion: “I don’t really feel as robust on the bike if I experience with out first doing chilly water immersion (CWI). I began day by 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 working. “As a aggressive bicycle owner in C grade/Cat 3 and Masters B grade/ Cat 2, driving six days per week, CWI has turn into a cornerstone of my routine. I take advantage of a salt water chlorinated pool at dwelling, immersing myself six occasions, 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 dwelling, 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 circumstances is clear throughout group rides in colder months. “There’s a buzz related to CWI, which I later came upon is because of dopamine launch. With 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 bother’ so that you get that hit of adrenaline, noradrenaline, cortisol and endorphins. There are these chemical substances speeding round your physique, making you are feeling invincible.”
It’s some extent 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 occasions.
“We discovered that WBC improves the general capability to supply 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 one 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 essentially untapped.
“Throughout train, core temperature will increase attributable to 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 cut back core temperature, thereby permitting cyclists to train for longer, or tolerate greater environmental temperatures for longer.”
The ‘Scottish bathe’
“Cryotherapy may be an efficient intervention for professional and beginner 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 possibly can apply cryotherapy, the simpler it’s more likely to be.”
Popping right into a cryotherapy chamber and even having a tin bathtub filled with ice on the finish of Sunday lengthy experience 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 method of acclimatising to chilly water immersion,” suggests Tom Haines. The deserves of alternating between cold and warm showers to induce among 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 dwelling.”
Potential pitfalls
Whereas cryo chambers are showing on the high-street and ice plunge tanks turn into the most recent must-have dwelling restoration accent, there are security issues amongst some consultants. Fast immersion in icy water poses dangers together with hypothermia, frostbite, and shock. Taking an ice-cold plunge has been linked to no less than one fatality within the US, prompting Professor Mike Tipton from the intense environments laboratory on the College of Portsmouth to subject 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 methodology’s emphasis on holding one’s breath and enduring excessive chilly publicity has are available for scrutiny amongst fears that the approach may deprive their mind of oxygen, growing the chance of fainting or hypoxic mind damage. Prof Tipton has reviewed a lot of the tutorial analysis accessible to this point and pours chilly water on most of the purported advantages of cold-water immersion for athletes. “Nearly all of present analysis is descriptive in nature and due to this fact contributes a restricted quantity to the understanding of the potential mechanisms underpinning the consequences of particular restoration methods,” he tells CW. “There are lots of areas that future mechanistic analysis ought to handle, with probably the most pertinent matters being the consequences of water temperature, hydrostatic stress and the appliance following totally different train sorts.”
Based on 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 decreasing irritation or mobile stress on this single-bout train mannequin.” As regards 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 speedy restoration after a sizzling race is ok, however dampening irritation throughout restoration is one thing I’m sceptical about. You don’t wish 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 wish to cease that?”
Elite biking groups aren’t about to ditch the chilly bathtub or post-ride ‘Scottish bathe’ simply but, although. As a way 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 bathtub isn’t doing you any hurt and feels good, then why not do it. However in terms of establishing a Lebron James ice tub within the backyard, the most effective 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 suitable diet and a good evening’s sleep.
