running and hot weather

hunnymonster

Given that we've all been talking about the effect of the heat wave on performance, I went away to look for the science. An interesting abstract I found was (below) but I don't have access to the full paper. Of those that I hace access to, there seems to be an unnatural tendency to obsession on rectal temperatures for marathon runners, so I've not delved too deep. Anyone got more info?

Heat and cold : what does the environment do to the marathon runner?

The marathon poses a considerable physical challenge for athletes of all levels. When combined with high heat and humidity, not only is performance potentially compromised, but health and well-being are also at risk. There are well recognised effects of heat and hydration status on the cardiovascular and thermoregulatory systems that can account for the decreased performance and increased sensation of effort that are experienced when competing in the heat. Elevated exercise heart rate and core temperature at the same absolute exercise intensity are commonly reported. Dehydration occurring during exercise in the heat and results in reductions in stroke volume, cardiac output and blood pressure, as well as a marked decline in blood flow to the working muscles. Recent work suggests that hyperthermia may have a direct affect on the CNS and the brain may contribute to fatigue during prolonged exercise in a warm environment. At present, evidence supports a significant role of catecholaminergic neurotransmission, but there are a number of metabolic and circulatory perturbations occurring within the brain that may also be important in the fatigue process.

i've got the full paper and will mail it to you if you want. pm me your e-mail address.

You get tired when exercising in the heat. Top notch research, that. :eek:

hunnymonster

lol, I assume they go into a bit more detail in the paper, I guess what I'm really trying to figure out is if the performance effect is quantifiable?

Thanks griffin100, have send you my email address.

Freudian slip there, HM.

Am I the only one who absolutely loves running in this weather? Sun on your back, no breeze, eyes stinging from the sweat...it gives a real 'summer holidays' feeling. Fair enough racing might be a bit harder, but training in it is fantastic (IMO).

I agree. Main problem is that we don't get enough of it so that when we race in it we are not well prepared. With no sceintific basis whatsoever, it has been proven that this glorious weather occurs on Weekends only on marathon days when you are running (if you are spectating, it will be raining), exam time & Mon-Fri during work hours thus giving us no time to acclimatise to it for racing.

It has actually been scientifically proven that the best weather tends to occur on Mondays. Something to do with less industrial activity happening over the previous two days creates a cleaner atmosphere and thus better weather.

I love running in a very hot condition I get energy from the sun.

Yeah Mr Spy, for 100 metres :pac: Even I did 12 x 100m yesterday evening.

Nice I am working 2morro so I have to go trainning earlier I cant wait to do some fly 60 flat out

I'm in New York for the summer, so I'm quite worried about the heat. I've decided to switch from the Berlin to the Dublin marathon so the toughest weeks of training will be after I come back to more temperate climes. Does anyone have any experience of training in New York or similar? Particularly in the summer.

I tried to run 11 miles last Saturday and the temp. was about 24 degrees. I think I ended up running about 9:30 pace instead of my target of close to 8:00. I wasn't properly hydrated to begin with, so I wasn't taking any risks.

Seres

the heat kills me when running , spent a couple of weeks in the north of brazil and everyday i went out running , i got out of breath really quickly , pace never really improved and always felt heavy.
