As you heard in the interview with Bob, race nutrition and GI distress is not limited to the consumption ofgrams of fat or carbohydrate. Hydration and mineral loss is also a factor. Bob mentioned the simple method of assessing your sweat rate in the interview, but I thought I would take a few minutes to elaborate on this and actually break down the steps that I use, so that you can do likewise to determine your sweat loss.
The basic process is this:
- Weigh yourself prior to your workout
- Weigh yourself after your workout
- Note how much fluid you consumed during
- Note (generally how much fluid you lost through peeing)
My spreadsheet has:
- Duration (minutes)
- Weight Prior
- Weight After
- Weight Change in pounds: multiply by 16 to convert to ounces
- Fluid Consumed
- Fluid Excreted
- Sweat Rate in ounces: ((H+I)-J))/(E/60)
- Use a reliable digital scale and make sure it's the same scale before and after
- Eliminate as many variables as you can by removing as many articles of clothing as is possible
- From the moment of the pre to post, note every ounce consumed or peed (estimate if necessary)
- Real life tips for assessing
- Be sure to note the average temperature as your sweat rate will vary
- I am now logging my pre exercise hydration as an insight to performance. It should not really affect this calculation other than to increase your pre-exercise weight measurement
