Heat the Certified Athletic Trainer’s Perspective Hi I’m Dr. Feder Jim Clover, MED, ATC, PTA Coordinator SPORT Author “Sports Medicine Essentials”
The Quest • Not to Kill anyone • To provide a healthy Environment for the Athletes • To get the best performance out of the athlete Secondary • Reasonable cost • With in the limitations of the staff (Coach’s, Athletic Trainer, students , etc.) • With the resources available
Temperature Regulation The hypothalamus is a small organelle within the brain which adjusts bodily functions through hormones which: -Increase heart rate -Begin the sweating mechanism -Increase blood flow to the skin surface
One Problem The Black Helmet / Uniform
Consistent daily monitoring of body weight • This allow athletes to recognize water deficits which require consumption of fluid • -2 to -3% of body weight, reduction of training duration/intensity • -4 to -6%, or consultation with an experienced physician • in excess of -7% out till cleared
How Much Water to Bring • Calculate Sweat Loss via Weight Charts • Weigh in before practice and out after in the same dress “shorts”
Problems • Two a Day – Three a day (needs to stop) • Both Male and Female (playing same sports) • What do they do in-between Practice • Not having a ATC on staff • Not knowing the sweat rate of each of your athletes
How much is enough? • More than you want just to satisfy your thirst • Sources of water are: 1. Fluids - 1 cup or 8 oz = 240 mL every 20 min • Foods - fruit & veggies are 90% water Add up the number of athletes, number of cooler (size of cooler) and figure about how much should be taken out and consumed Bring their own
What to drink & Eat • Electrolyte drinks (e.g. Gatorade) are usually not needed for typical North American diet (can be used for first aid). • Stay away from caffeinated, carbonated, diet drinks, and alcohol as they take water out of your body. • Water is the best; juices and/or no caffeine sport drinks are also good (juices contain energy restoring glucose). • Eat 4 meals a day
Things to check • Look for typical heat strain symptoms; feeling over-heated, fatigue, headache, nausea, weakness, dark concentrated urine, etc. • Sweat that drips off your body no longer allows for cooling by evaporation; thus, unless there’s another medical reason for it, this is a sign that your body is heating up • Let the athlete change t-shirts.
Control methods -Drinking adequate amounts of fluids -Protective clothing (light colors reflect heat) -Protective equipment (vests, fans) -More?
What else are they doing? • The commissioner banned players with minor-league contracts from taking ephedra in the wake of Bechler‘s death
Administration Wants a number • Temperature 100 -106 degrees (Based on what?) • Heat Index (does it work everywhere?)
There is a number www.hqinc.net
The History ofTHE PILL • The Core Temp Ingestible Core Body Temperature Sensor was developed in the late 1980s by HQ Inc., of Palmetto, Florida • Costs around $30 each • The pill relies on a temperature-sensitive quartz crystal temperatures ranging from 60 °C to 150 °C.
Is This A Special Sports Pill?NO! Sports physiology Firefighting Research & medicine Agriculture Occupational safety Food Production & Safety Military Industry
The Process • Upon swallowing, the vitamin-size pill acts as an internal thermometer, providing continuous readings of a player's body temperature, which can be picked up by a sensor placed against the low back. • Pills are ingested a couple of hours before the start of practice, allowing the capsules time to reach the small intestine, where core body temperature readings accurate to within 0.1 °C can be taken. • The capsule remains in the body for only 24 to 36 hours before it is eliminated.
TheScience • Temperature readings are transmitted wirelessly to a handheld data recorder. • The receiver is held to the low back, and the handheld device's antenna retrieves the original temperature data.
Heat Monitoring • Allows for real-time on-site monitoring • Provides absolute vs. relative data immediately • Temperature patch reflects internal (core) body temperature • SportsTempThermostrip • www.sportstemp.com • $1.50 each
Acclimatization • Heat acclimatization is specific to the stress imposed on the human body. For example, passive exposure to heat induces some responses, notably an improved ability to dissipate heat. • Complete heat acclimatization requires up to 14 days, but the systems of the body adapt to heat exposure at varying rates.
Acclimatization • The early adaptations (initial 1-5 days) involve an improved control of cardiovascular function, including expanded plasma volume, reduced heart rate, and autonomic nervous system which redirects cardiac output to skin capillary beds and active muscle • Excess dietary water and electrolytes do not speed the process of heat acclimatization.
