The Science Behind Ice Baths: How Cold Therapy Boosts Recovery
Ice baths, or commonly referred to as cold water immersion or cryotherapy, has grown in popularity as a method of recovery among many athletes to help reduce soreness of muscles, enhance recovery and even enhance performance. But what specifically makes ice baths give those levels of benefit? Before proceeding with the analysis of this frightening method, let us turn to the science that stands behind it.
How Ice Baths Work
An ice bath is a procedure that can be taken in a bath or a tub and the person submerges his or her lower body into water that ranges from 50-59°F or 10-15°C. This is because during cold weather, the skin’s blood vessels have to restrict their flow in order to keep the internal heat from dissipating. These anabolic effects stress vasoconstriction and leave reduced blood supply in the limbs and divert blood towards the core of the body.
When one gets out of cold water, the situation is reversed, the blood vessels expand and saturate muscles with nutrients and waft away metabolic wastes. This fresh blood may help alleviate soreness and fasten the rate of recovery in the team. This also revealed that cold temperatures lowers tissue temperatures, cellular metabolic rate and thus oxygen consumption and inflammation.
Gains in Exercise Recovery
Quicker Overload Break Between Training Sessions
A number of researches give some information that ice baths can be useful for the purposes of competition to enhance recovery between hard training sessions. In one study, 16 endurance cyclists were monitored in terms of the type of training they undertook and the intensity, duration and frequency over five consecutive days. The cyclists went for ice bath exercise right after the training. Scientists determined that the ice baths minimized presences of various markers of muscle and inflammation, as well as increased oxygen saturation. Finally it enabled the cyclists to sustain the same performance across several days and this renders Pneau as effective for multiple day events as compared to passive recovery.
Reduced Muscle Soreness
Consuming the cold water of an ice bath has once more prove reduce the onset of next day DOMS after intense training sessions. DOMS is characterized by a deep muscle soreness for 24 to 72 hours after taking part in activities that one is not used to or he/she has not practiced much. This is believed to be arising from damage to muscle fibers and soreness.
Several studies show that athletes who apply ice baths have less muscle soreness compared to those athletes who opted for passive recovery process. A study found out that the use of ice baths caused a decrease in muscle soreness of 26% more than the placebo group especially among the long distance runners the morning after the marathon. Scholars also postulate that because cold therapy has been claimed to inhibit cell metabolism and blood flow to the traumatized area as well as the activity of pain receptors, it acts more as a remedy to inflammation.
Faster Super Compensation Period
Numerous investigations reveal that ice bath enables athletes to preserve their power, strength, and endurance over multiple hard training days as compared to other passive recovery.
In one of the studies with healthy young males, the subjects conducted heavy resistance training sessions for the arm muscles for 4 consecutive days. Members in one group, had to take ice bath after exercising while the other group did not. Hence, percentage change on muscle soreness, muscle function loss and blood biomarkers of muscle damage were significantly less pronounced in the ice bath group than in the control group after 4 days.
Further studies revealed that ice bath encouraged quicker return to optimal power of match – related competitive rugby players in their 40 meter sprint speed during a 4 day tournament as opposed to the control group.
Boosted Blood Circulation
In addition to exercise recovery, ice bath enthusiasts are quick to point out that acute and transient cold stress is followed by a rewarming that enhances cardiovascular circulatory competence. It is believed that constriction and dilation of blood vessels as such a pump for elimination of the waste products and for the purpose of circulation similar to massage.
Others postulate that recurrent usage might cause a reduction of hypertension and enhancement of vascular profile. However, more research has to be done to support these hypothesized later, long-term cardiovascular advantages. If you suffer from heart issues or any other conditions, it is best to seek your doctors permission before starting cold therapy.
Potential Risks & Precautions
While the potential upsides are plentiful, ice baths do come with some risks if used improperly:
Hypothermia – It is possible to get a wrong temperature if a person spends too much time in water temperature below 59°F. The majority of them suggest that the child should spend no more than 10 to 15 minutes in a single session.
Potential freeze hazards - The excessive cold may also cause Paresthesia and even affect the tendons, muscles, and nerves of the hand, feet and other limbs.
Blood pressure heart issues – Extreme temperature change puts pressure on the heart. Ice baths are unsafe for people who have hypertension, cardiovascular disease or Raynaud’s syndrome.
For safety, begin with the short time, it’s advisable to spend in the car 30-60minutes starting and check the feeling of hands and feet after getting out. Ice baths should only be administered 2-3 times per week only when the pain is at its worst to give muscles enough time to recover in between. Listen to your body – any tingling or numbness, pain, or if your skin darkens – then you should get out of the sun.
Ice Bath Benefits: The Bottom Line
Ice baths are effective when it comes to enhancing muscular recovery from exercise-related muscle damage, relieving soreness, increasing exercise recovery, and improving the circulation of blood. Just don’t overdo it! It’s vital to pay attention to the body sensation so that one does not end up on the negative side such as hypothermia or nerve damage. If unsure do consult with your doctor before going ahead.
