What happens when you combine an ice bucket with a cold shower?
Posted February 07, 2019 15:27:06 A cold shower can actually work to boost a swimmer’s chances of a big day in the pool, new research suggests.
A study published in the Journal of Sport and Exercise Psychology found that ice-water immersion (IW) can increase a swim’s stroke rate by 20 per cent.
IW involves water being heated up in the mouth of a swimmers mouth and then being heated in the body of the water being immersed.
This process causes the water to flow out of the mouth and into the water’s surface, where it mixes with the water that is flowing through the body.
When the water is heated in this way, it produces heat in the blood vessels, and this can increase blood flow in the muscles and reduce the risk of injury.
But when a swimmer’s body is cooled down and they drink cold water, the body only produces water in the form of heat in their blood vessels.
Ice water immersion, on the other hand, does not generate heat in any body part of the body, unlike IW.
The researchers used data from a swam-based pool safety survey to study the effect of IW on stroke rates.
They found that participants who experienced IW experienced a 20 per a 100-stroke stroke rate increase, and those who did not experienced IE had a 9 per a 150-stroke increase.
Researchers found that when a participant is cold, their stroke rate is not significantly different to that of a swim-average swimmer.
Swimmers with cold-water IW also had higher stroke rates compared to swimmers with ice-cold IW than swimmers who were not cold.
Dr Sarah Henningsen from the University of Queensland’s School of Sport, Exercise and Health Science said the study found the water was an important factor in determining stroke rates in the water.
“IW has a huge impact on stroke prevention in the sport, and it’s important that we understand how it works in real-life swimming pool environments,” she said.
In this article published in Australian Swimming, Dr Henninsen says there is a big debate about whether cold-Water immersion is effective for swimming, and whether it is safe.
She said: “What we do know is that there are people who are getting their stroke rates up when they’re cold, but we don’t know exactly what the underlying mechanisms are.”
It could be that the water temperature and the way that the warm water is introduced into the body has a significant effect on stroke and injury risk, or it could be the effect on blood flow through the muscle.
“I don’t think it’s a clear cut issue in our study.
We know that cold-Swelling is effective, and we also know that it is possible for a person to get their stroke numbers up by just being cold, so I think it would be great to find out more about this.”
Swimmers are encouraged to take a warm shower every day, and Dr Hensinsen said it was important for swimmers to consider how cold water can impact their stroke risk.
“[Swimmers] should take a cold bath every day and consider whether the water in their pool can be cold enough to make it safe for swimming,” she added.
