Downs and ups
Monday, June 25, 2012
Down: I FINALLY moved the scale! This week's 3 pound loss puts me at 50 pounds gone. Whoop! I have been dancing around 201 since November. Lowest in March was 199 point something: onederland, which of course freaked me out, I ate excess, crawled back up to 201, 203. Working, working, working to get that scale down. Plenty of non-scale victories to sustain me, although the scale is a big factor for me. What a nice surprise this morning.
Motivated by the scale victory, I set out to run (my kids say it's really a jog cause I go so slow). Hoping for 3 miles, ready to be happy with 2.7, depending on my body feedback. I left 3 hours later than usual; in Texas speak, that's 3 hours hotter. It was probably 88 or so. Good bit of humidity. Still, just a run. No biking before, no swimming before. I was really surprised when about a mile and a half, I couldn't catch my breath. I slowed down a little, my legs didn't want to keep going. I walked a bit, finally felt my lungs expand fully, started running again. A little dizzy, a little nauseous, couldn't get a deep breath, so I walked home. I've been tri-training almost 2 months. Bonking and injury were two of my big concerns, so I've tried not to push myself too hard.
Being a biologist, I want to know: why today? Breakfast was a banana instead of my usual yogurt (just a run, no swim, no bike). Was I missing my proteins? I get the idea that exercise needs carbs, readily available energy. I can't equate slamming sugars with working out: What about the insulin spike 20-30 mins after sugar? What about the microtears in muscles that need protein to repair? What about the long term energy release from amino acids and protein? Those myosin heads pulling with every muscle contraction cycle need amino acids! (yes, a little anatomy is a dangerous thing).
Heat and humidity, I'm sure, played their part. Still, I drank 2 glasses of water before I left.
Yesterday, I fell off my bike: fight or flight kicked in, I know. As I was walking home this morning, I imagined all of my energy reserves (glycogen, anyone), burning off with the fight or flight adrenaline yesterday, especially in my shaky legs. I imagined my muscles this morning during the run looking for energy, hey, where did it all go?
I have been on anti-anxiety meds for several years (hello, parenting 3 ADHD kids). The past month or so, I've been slowly decreasing my dosage. I've wondered in the past whether the meds helped my heart rate and respiration "stabilize". Maybe the decrease in meds, improper fuel, extra dose of heat = bonk?
So: the ups: my heart rate, respiration, body temperature, blood flow to my skin (my daughter asked what was wrong with my face cause it was so red). Another up: my endurance and confidence. Yes, I bonked, which has been along term worry for me. I recognized it, slowed down, got myself home, so it wasn't so bad. If I bonk during the triathlon in 3 weeks, I will simply walk (and drink plenty of water!)
