I’m doing a clinical trial (99% sure I have placebo, and supplement was meant to increase, not decrease performance), did a VO2 test in June, and another today (3 months apart). I went from 66 down to 57. This was despite an increase in training and weight training.
8 weeks prior to test 1, I averaged 225 TSS (stdev 110) per week. So pretty low and irregular. Ramp test a few days before showed 219.
After test 1, I started resistance training at the gym (all over, but with a focus on squats, lunges, deadlifts, leg press). I did this for 6-8 weeks before a lockdown meant the gyms closed. I put on about 1.5kg in muscle I reckon.
8 weeks prior to test 2, I averaged 350 TSS (stdev 80). So more TSS and more regular. Also a greater reliance on sweet spot and using TrainNow more often (mostly sweet spot, threshold and vo2). Ramp test prior showed 238 (8% increase).
So yeah. A little perplexed/disappointed with the results. Physio suggested that my oxygen uptake was much lower this time. My lactate was higher than last time as well. Going to focus on more VO2 max work instead of sweet spot and try again in a few months.
Anyhow, thought some of you may be interested.
