Change was certainly in the air on Tuesday. Instead of upper body strength, it was met-con madness. Instead of breezy, Spring weather, it was 80% humidity. High humidity = sticky floors, so it must be time for some plate pushes.
Working with a partner, and with only one person working at a time, divide the reps amongst each other however you see fit, although the preference was for an even division of labor. Each pair must complete all the reps of one exercise before moving on to the next.
1 plate push was equal to a trip to 1/2 court and back, although a few of the craftier pairs split the reps into 1/2 court trips (so P1 did a 1/2 court push, and then P2 did the other 1/2 court push to complete the rep – very smart).
So, yes, it was somewhat humid on Tuesday. However, all jokes regarding the weather aside, Tuesday night is a great reminder to all of us of the need to hydrate properly as the summer weather starts to roll in. A few quick facts for ya:
Human’s are 45-70% water.
Muscle tissue is 75% water.
A human can survive 4x longer without food than without water.
Fluid loss as a % of bodyweight:
1% = Elevation of core body temperature, impaired performance
3% = Significantly impaired performance
5% = Cardiovascular Strain
7% = Decreased ability to regulate heat
10% = Heat Stroke, unconsciousness
At 90 degrees and 40% humidity, the heat index (what the temperature feels like to the body) is roughly 92;
At 90 degrees and 60% humidity, the heat index is 100 degrees;
At 90 degrees, and 80% humidity, the index is 112 degrees.
The problem with higher humidity, besides making us feel hotter and more uncomfortable, is that we actually become hotter. Our bodies first line of defense to getting hot is to sweat – as air absorbs the moisture from sweat, we feel cooler. Except, when it’s humid, the air, already saturated with water, doesn’t absorb the sweat-moisture. Thus, we don’t feel cooler, and our bodies have to compensate by working harder and harder to try and cool us down. Of course, when sweating doesn’t work to cool us down and we continue to heat up, overheating results, which causes loss of the water and chemicals that the body needs. Overheating, or more commonly, heat exhaustion, can lead to dehydration and chemical imbalances within the body.
Outside of activity, you should be consuming half your body weight in ounces of water a day. For more on that – and since everyone’s been digging the inclusion of videos lately – I refer you to coach Max Wunderle ‘s (of CrossFit Endurance/Tri-Max Fitness) take on the subject:
With that, drink up, and we’ll see everyone back on Thursday (in which, I swear, there are no planned plate-pushes…)
