“Women are not small men.”

“taking a broad view of the world and having a lot of tolerance and patience and making myself grow in whatever environment I’m in”

Key Discussion Points:

  • How did you get into your field of work/research?

  • What has you most excited these days?

  • Why can’t both sexes hydrate the same way?

  • What hydration sources out there being pushed commercially actually cause dehydration?

  • When are the best times to hydrate? Is there a wrong time?

  • How does dehydration play into injuries?

  • How should athletes hydrate properly while traveling by plane?

  • What eating habits should athletes have on 2-3 hour practice days?

Key Lessons:

  • If you start with good habits, you will further your career down the road

  • Most sports drinks are designed to replace carbohydrates first, and then provide some fluid second

“A standard sports drink has between 6-8% carbohydrate solution..when you look at that was a chemical..physiological standpoint...that concentration of carbohydrates are too concentrated to flow into the body easily.” SS @ 13:03

  • You can remove stress by watching what you are eating and drinking

  • Optimal hydration will better your overall performance

  • There is NO pure water in the body; plain water isn’t the main solution for hydration

“If you are just drinking plain water, you’re not really maximizing what your body recognizes as the solution..so just a little bit of sodium in plain water..that will allow the body to pull that fluid in.” SS @ 18:28

  • Hydrate throughout the day with MORE than just water

“...its eating watery fruits and veggies, its drinking mineral water that has the sodium in it or its making you own sports drink with 500 ml of water (16oz), dash of salt and a little bit of maple syrup (tsp.)..you’ll get some glucose..sodium, and then you’re going to get your fluid and its going to be absorbed.” SS @ 18:48

  • When dehydrated, you are prone to tissue tears, cramping, ACL injuries,etc.

  • Compression tights during travel help with getting up and walking around as much as you can to prevent swelling in the ankles

  • Have your products to make your protein drinks WITH you on your flights

“12-13 hour flight...having two protein base drinks on the flight...the protein helps with the hydration aspect and the amino acids counteract some of the jet lag.” SS @ 24:37

  • You want to maximize the food before you have practice

“..at least 90 minutes before you start and you can top up with  snack..a 150 calorie snack, about 30 minutes before you start training, so you’re going to be well fueled.” SS @ 26:56

  • Stay hydrated all the way through practice with “functional hydration drinks” (glucose, sodium, potassium)

  • HYDRATE and FUEL for whatever you are doing

The Importance of Thermoregulation
The way your body deals with stress after exercise or extreme conditions is through thermoregulation; through changing constriction of vessels, through sweating, respiration; without thermoregulation there is no human.

Definition of Being an Athlete?

"A combination of mind, body, and spirit. There is not one without the other. You can’t be a complete athlete if you aren’t mentally strong and also aware of what you’re doing and how your body fits in space and time. Physically you can’t be an athlete without all the training components and nutrition components and spiritually, without that inner drive and the awareness of how you give and take from others, you can’t really be a complete person or a complete athlete. " -Dr. Stacy Sims
