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

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
Consistent daily monitoring of body weight

ProblemsTwo a Day – Three

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

Turf vs Grass
![Page 13: Jim Clover, MED, ATC, PTA Coordinator SPORT Author “Sports Medicine Essentials” Hi I’m Dr. Feder.](https://reader035.fdocuments.us/reader035/viewer/2022070407/56649e185503460f94b03f8b/html5/thumbnails/13.jpg)
All Athletes are not built the same
![Page 14: Jim Clover, MED, ATC, PTA Coordinator SPORT Author “Sports Medicine Essentials” Hi I’m Dr. Feder.](https://reader035.fdocuments.us/reader035/viewer/2022070407/56649e185503460f94b03f8b/html5/thumbnails/14.jpg)
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
min2. 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
![Page 15: Jim Clover, MED, ATC, PTA Coordinator SPORT Author “Sports Medicine Essentials” Hi I’m Dr. Feder.](https://reader035.fdocuments.us/reader035/viewer/2022070407/56649e185503460f94b03f8b/html5/thumbnails/15.jpg)
What to drink & EatElectrolyte 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
![Page 16: Jim Clover, MED, ATC, PTA Coordinator SPORT Author “Sports Medicine Essentials” Hi I’m Dr. Feder.](https://reader035.fdocuments.us/reader035/viewer/2022070407/56649e185503460f94b03f8b/html5/thumbnails/16.jpg)
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.

-Drinking adequate amounts of fluids
-Protective clothing (light colors reflect heat)
-Protective equipment (vests, fans)
-More?

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.
The History of THE PILL

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.
The Process
![Page 30: Jim Clover, MED, ATC, PTA Coordinator SPORT Author “Sports Medicine Essentials” Hi I’m Dr. Feder.](https://reader035.fdocuments.us/reader035/viewer/2022070407/56649e185503460f94b03f8b/html5/thumbnails/30.jpg)
The ScienceTemperature 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 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
![Page 34: Jim Clover, MED, ATC, PTA Coordinator SPORT Author “Sports Medicine Essentials” Hi I’m Dr. Feder.](https://reader035.fdocuments.us/reader035/viewer/2022070407/56649e185503460f94b03f8b/html5/thumbnails/34.jpg)
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.
Acclimatization
