Veteran 434 Apex, NC | Subject: Trick for dealing with the heat So I've been doing this for a few years now and have heard most tricks for dealing with the heat. But one I hadn't heard as much and hadn't tried is ice down your shorts. I raced Austin yesterday in warm (I personally call it hot but I know for the Texans it's not) temps and tried this. It's the single best thing I've tried so far. Tight tri shorts keep it all trapped right there where your femoral arteries are and yes, it cools things off in general down there. The ice easily lasted until the next aid station with ice. Just an FYI. |

Master 2406 Bellevue, WA | Subject: RE: Trick for dealing with the heat Ice in the shorts is one of my solutions for running in 90+. Another solution I commonly use is to run with a cup of ice in one hand, and hold the ice in the other hand and let it melt, then get more ice. Ice melting in the palm of my hand seems to make a big difference without any "wow that's cold!" shock effect. I don't like ice under the hat because I wear contacts and water running into my eyes is bad.

Veteran 434 Apex, NC | Subject: RE: Trick for dealing with the heat Originally posted by JoelO No chafing issues? Nope, none. The only downside is that you constantly look like you wet yourself but hey, the cool kids are into peeing themselves during the race anyway, right? |

Regular 549 | Subject: RE: Trick for dealing with the heat Watched a bit of Kona online and saw many people doing this. The commentator said the same.....Ice along the femoral artery cools the body. And the leader at the time was doing it at every aid station. |

Extreme Veteran 1986 Cypress, TX | Subject: RE: Trick for dealing with the heat Originally posted by hessma The commentator said the same.....Ice along the femoral artery cools the body. Applying ice to the femoral artery does cool the body. That said... The huge problem with this is there isn't enough ice, time, or surface area to even put the smallest dent in your core body temperature. Basically the only way one can cool down quickly in that regard is for the body to be immersed in a ice/cold water bath. Applying a small bit of ice to the major arteries is like putting a bandaid on a gunshot wound. Not enough ice applied for not enough time. It's a perception/placebo effect. It's a very temporary cooling of the skin temperature. Two seconds later you're just as hot as before. I'm not knocking the placebo effect as the mental game plays a role but perception is not reality and the reality is that applying a tiny bit of ice to a tiny part of your body doesn't do anything to your core temp. There have been some PubMed articles. The most cited article on exercise-related hyperthermia is this one: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2629045/ Ice-Pack ApplicationSome medical professionals recommend applying ice packs or ice bags to the major arteries of the body as a means of whole-body cooling.35,36 The most common placement sites are the neck, groin, and axillae. The goal of this treatment is to cool the blood as it is pumped through the carotid, axillary, and femoral arteries. However, even when ice bags were applied to the entire body (24 to 28 bags of ice), cooling rates were in category C (0.028°C · min−1).19 In fact, these results suggest that it would take approximately 110 minutes to cool an EHS patient from 42.2°C (108°F) to 38.89°C (102°F) with this method. Given proper planning and available resources for category A treatments, the use of ice packs or ice bags for the treatment of EHS should be discontinued, because the extraction of heat from the body is ineffective for the body temperatures typically associated with EHS.19 So a few ice cubes isn't going to do jack. There was also a good discussion on ST a few years ago in which some guy who works for/with the Dept of Defense designing cooling systems for soldiers commented that there's really no way to effectively cool oneself during a race. The only way to do so was through immersion or some bazillion dollar high-tech ice vest that's not at all practical. He was a fan of the evaporative cooling effect, not that it cooled the core at all but it makes your skin feel cooler which makes you think you're cooler. Some of his quotes: The company I work for sells high end cooling systems to the US Military for helicopter pilots and tank crews. I'll give you my two cents on the subject coming from someone who has personally sold cooling systems for some of the most demanding temperature requirements out there for the past 7 yrs and also has a graduate level engineering background. Note that the systems we provide are vapor compression (like your fridge) but rather pump cooled liquid to a vest worn under a soldiers flight gear (like wearing a radiator). In our ever present quest to field cooling systems for the average infantry soldier on the ground who is very weight constrained, we've examine many different systems and technologies. None of them are effective enough at a physiological level and yet practical (i.e. you're not lugging around 10lbs of batteries, etc). The military has examined hand cooling in a manner much more complicated than you described. What they found was that your hand basically needs to be in a vaccum environment to bring your blood vessels to the surface to have any appreciable cooling effect. There are some commercial products out there that do this...i think one is called Avacore. It's defnitely not race portable though. We've examined targeted cooling on specific parts of the body (groin, kidneys, back of neck, etc) but again you can't get enough cooling into such a tiny surface area when combining the mass flow rate of blood past it. I'm an engineer / business development guy for a defense contractor and for the last 7yrs have worked with the US Army on cooling systems for soldiers. We've had systems fielded in Iraq / Afghanistan for 10yrs and I've had the benefit of working with some of the top government researchers in human cooling and human factors. We use vapor compression as a cooling medium which is not feasible for a triathlon since no one wants to carry around 10lbs. But our system uses a vest that targets the core body of the wearer. The rationale behind this is that you cool the heart and it pumps out cool blood to the extremities. Again this solution isn't feasible in a tri because no one wants to wear a vest! |

Regular 606 Portland, Oregon | Subject: RE: Trick for dealing with the heat Originally posted by hessma Ice along the femoral artery cools the body. Does it really? I can definitely agree that it will mentally cool you off. But is the energy consumed melting the ice, warming it up and evaporating it off sufficient to actually make a significant difference on body temp? According to the math here: https://answers.yahoo.com/question/index?qid=20100528075246AAuz8j8a single ice cube could potentially decrease a 70kg body (of water) by about 1.25 degrees C. So I guess as long as all that heat comes from the body, and none drips off before vaporizing...maybe it would be pretty helpful. A cup of ice may be able to bring you down a degree or two in the real world. Cool. Edited by dfroelich 2014-10-27 6:29 PM |

Master 3205 ann arbor, michigan | Subject: RE: Trick for dealing with the heat The real trick is to heat acclimate for the two to three weeks prior to the race. Then you will be well prepared to tolerate the high temperatures. All of the tricks are helpful but there is no substitute for training in heat to get you ready to race in heat. I did two weeks in sweatsuits, wool hats, running tights, multiple layers, etc leading up to my last really hot race and it made a pretty amazing difference on race day. |

Veteran 434 Apex, NC | Subject: RE: Trick for dealing with the heat I completely defer to the science on this one. Thanks for the information. Still, the ice down the shorts method seemed to work better than anything else I have tried. Maybe there is a mental benefit of ice on the privates. What was the Seinfeld episode with George at the beach? I guess that was different. Anyway, I'll be doing this at the next race since I can't submerse myself in ice water during the race. |

471 | Subject: RE: Trick for dealing with the heat 3 - 4 ice cubes inserted deep into the anal passage is very effective at bringing the core body temperature down. It does take a bit of technique to surreptitiously get the cubes up there, but with practice it can be done quickly and smoothly without attracting too much attention. They need to go longways by the way, not sideways. |

RIchard Hammond from the UK Top Gear did a series called Miracle of Naute, on season 1 ep. 3. he looked at heat control. He was looking at ways huskeys control their heat. One way was passing a lot of their blood through their paws on to the cold ground. I can't find any clips but he used something called CoreControl the Cooling Glove (I think) which cooled the blood passing through on hand. He was looking at cognative function, more than athletic function, but it worked very well. So the ice in a cup in your hand does have some backing! |

Master 8247 Eugene, Oregon | Subject: RE: Trick for dealing with the heat LOL I thought I was the only one who actually stuck my head in the big cans of ice water! Done it in several races in Vietnam when I just thought I would puke from the heat, and provoked a pretty negative response from a race official in Singapore when I did it there at the finish of a race. I guess it isn't that sanitary, but if it's that or puke/pass out, I'm headed for the ice bucket! Edited by Hot Runner 2014-10-28 7:29 AM |

Probably not as effective as putting it in my shorts, but it seems to work and it's easier to do while running. |

Extreme Veteran 1942 In front of computer when typing this. | Subject: RE: Trick for dealing with the heat Smoom, I do that all the time in races. I actually like doing it with a tri top and find that if I throw ice down my back it settles right over my kidney area, which feels really good when you are too hot! And I've done the "down the pants ice" too- feels good and I've never had chafing issues either. My thought is that if it is hot enough for you to want to do that, you are already pretty wet anyway! The only thing I don't like is that sometimes the water drains into your shoes and you end out running in soppy shoes, but I would take that over the heat any day! |

Veteran 512 Tempe, Arizona | Subject: RE: Trick for dealing with the heat I remember the first time I tried this (ice down the shorts) during the run section of my first Olympic in Arizona. It was brutally hot (101°F, no wind and no shade) and on the 2nd loop I was dumping water and ice on my head, putting ice in my bra, in the small side and back pockets of my shorts, and down my shorts. I started giggling as I was slowly overtaking a guy, and he asked me why I was laughing. I replied "One tip to remember, don't put more than one ice cube down your shorts at a time, they end up in one location and start jiggling around - it's very very distracting". He burst out laughing and had to stop! Obviously, I overtake people by distraction For me, the best thing was putting ice in my side and back pockets of my shorts, especially the back pocket - it worked really well and if I zipped the pocket up, the cubes lasted quite a long time. |

I did this somewhat accidentally in Augusta. Felt good, man. |
