Do Ice Baths Actually Improve Muscle Recovery? Read This Before You Try It Out

‘Cold water immersion’, extra generally often known as ‘ice baths’ are routinely used by skilled athletes after sports activities occasions.

Dipping into ‘icy’ water (normally round 10 °C) for five to 10 minutes is claimed to enhance muscle restoration and improve future sports activities performances, however what’s the science behind these claims?


We requested 5 specialists in train physiology: Do post-exercise ice baths improve performance? Here is what they stated.

What occurs to muscle tissue once they get chilly?

Many individuals use ice packs or a bag of frozen peas at dwelling to cut back ache and swelling if they’ve pulled a muscle.

Johanna Lanner, an skilled in muscle physiology from the Karolinska Institute in Sweden, explains how this works:

“Cooling i) reduces nerve impulse transmission and thus reduces the level of pain perception and ii) induces constriction of blood vessels in peripheral tissues (e.g., muscle) which results in reduced fluid diffusion that may assist in reducing exercise-induced acute inflammation.”

Llion Roberts, an skilled in train physiology from Griffith University in Australia, says: “Cold water immersion can be identified to assist restore heart rate variability, the variation within the millisecond time durations between successive coronary heart beats.”

Interestingly, ice baths can affect our minds in addition to our muscle tissue. James Broatch, an skilled in train physiology from Victoria University in Australia, undertook a analysis examine which compared “the effects of an ice bath with a placebo condition that participants were tricked into thinking was as effective as an ice bath”.


In the placebo situation contributors had a heat bathtub with what they thought was a particular ‘restoration oil’ however was really only a pores and skin cleanser.

Broatch says “participants in both the ice bath and placebo conditions rated their belief in the benefits of their assigned recovery condition similarly, which in turn translated into a similar recovery of leg extension strength over a 48-hour post-exercise period.” 

What impact do ice baths have on muscle restoration after train?

Lanner says that ice baths are efficient at “reducing the symptoms of exercise-induced delayed onset muscle soreness i.e., pain and stiffness experienced in muscles several hours to days (usually 24-72 hours) after unaccustomed or strenuous exercise”.

For this motive, ice baths are commonly used for muscle restoration after sports activities competitions. 

What impact do ice baths have on train efficiency?

As ice baths assist muscle tissue get better, it could comply with that they will enhance sports activities efficiency. Unfortunately it’s not that easy – Hakan Westerblad, an skilled in mobile muscle physiology from the Karolinska Institute in Sweden, says “scientific studies show varying outcomes regarding the effect of post-exercise ice baths on subsequent performance, with results ranging from minor positive effects, via no effects, to negative effects.”

One of the problems with measuring the impact of ice baths on train efficiency is that there are a lot of several types of train, equivalent to endurance or power coaching.


Roberts says “somewhat surprisingly, after strength exercise, cold water immersion may in fact hinder the benefits of exercise”.

He and his colleagues “found large reductions and/or blunting of the desired results from strength training such as increasing strength and muscle mass, and cellular improvements within the muscle. This was most likely a result of the cold water negatively interfering with the natural protein and cellular responses that happen in the muscle after each strength session.”

Effects on endurance coaching could also be fairly completely different. Christopher Mawhinney, an skilled in sports activities science from Mahidol University in Thailand, says: “Interestingly, there is evidence which suggests that cooling the exercised muscle increases the cellular signal which turns on mitochondrial biogenesis”. 

Mitochondrial biogenesis is when cells improve their numbers of mitochondria, that are buildings that launch vitality. Mitochondrial biogenesis is without doubt one of the optimistic results that comes from endurance coaching, so ice baths may assist to amplify this profit.

The results of ice baths on train efficiency differ depends upon what sort of train is concerned.

Rogers summarizes: “Cold water immersion following strength exercise should be undertaken with caution or avoided. Its use following one-off circumstances like big sports events or endurance exercise is recommended, and may even provide additional benefits for subsequent endurance exercise performance.”

The takeaway: Don’t use ice baths to enhance your power coaching, however they might be helpful for endurance workouts.
