My local pool has just raised the water temp to 30 ' C ( 86 ' F ) ! At this temp I am exhausted after 4 lengths. A full workout of 60 to 90 mins is impossible without suffering heat exhaustion. They have already had 1 swimmer collapse on poolside after swimming hard for 40 mins.
This has happened because a ' disabled swim group ' who use the pool for 45 mins once a week keep complaining about how cold the pool is. The pool management can't figure out the pool temp software so the temp is set that high for 24/7. It used to be 27' C ( 80.6' F ) and was then raised to 28'C (82.4 ' F ) 1 year ago.
I can't set workouts for my club that cause heat distress if carried out so it is a nightmare. My training is on hold until i can change this and I will have to move my masters club to another pool if not changed. Maybe ' Shaky's ' pool has space for us ?
Emmet Hines in his book says that 82 ' F ( 27.7' C ) is ideal for training, and that anything over 84' F ( 28.4 ' C ) is too hot.
Does anyone else suffer through hot water temperatures ? Can anyone recommend online research that I can use to prove the dangers of excercising in hot water ?
"At temperatures above 78 to 82 degrees Fahrenheit, chlorine dissipates faster, algae grows better, and the formation of scale (calcium carbonate deposits) is more likely to occur." From Pool Chemistry Fact Sheet (link is a pdf)
"Water chemistry is another factor that comes into play when the water is too warm it is very problematic to treat warm water with chemicals. Bacteria, algae and other organisms thrive under warm water conditions this is obviously harmful not just for athletes but the general public in a commercial swimming pool, for competitive pools the water should be no higher than 82°F (28°C), for recreational pools the recommended maximum is 84°F (29°C)." From What is the ideal temperature for a commercial pool.
"When your pool water heats up to around the 85°F (29°C) mark, bacteria and algae get nice and comfy, and start reproducing at exponential rates. Keeping your pool below that mark won’t get rid of algae and bacteria completely, but will make it more difficult for them to bloom and grow and become a problem." From What is the perfect pool temperature.
I have used this info successfully in the past when swimming in an overheated pool. The swim instructor complained that the kids were too cold at 89F. When I pointed out the possibility of cooties (technical term) from bacteria and more work/chlorine shocking required, they put a lock on the thermometer and set it at 84F.
