Strava Data Shows Huge PR Gains Following Performance Lab Sessions with Misti Walbridge
Updated: Jan 2, 2020
This data and writing is pulled from a review of the Performance Lab by third party review at Sicklines.com, a mountain biking website. Toni Walbridge is the author of the results below with everything in quotes written by him.
"Misti has been riding mountain bikes for the better part of 20 years. She does not race but does ride 4 to 5 days a week on average and enjoys the sharp end of riding that the PNW and BC have to offer."
Bellingham Performance Lab with Dr. Steve Noble
Athlete: Misti Walbridge
Duration: May 21, 2018 - June 7, 2018
Performance Lab session breakdown: Six 30 minute sessions.
Before treatment data using Strava for Personal Record (PR) accumulation during time frame April - July, 2017:
April, 2017: 37 PRs (note sessions did not start until May 21, 2018 so we are looking back at the month prior to any treatment as a comparison)
May, 2017: 46 PRs
June, 2017: 56 PRs
July, 2017: 44 PRs
After treatment data using Strava for PR accumulation during time frame April - July, 2018:
April, 2018: 52 PRs (see note above for April, 2017)
May, 2018: 61 PRs (Misti's first session in the PL was on May 21, 2018)
June, 2018 105 PRs
July, 2018: 142 PRs
"In the chart below, the darker colors equal more PR’s. Below you can see her last four years of PR data. Examining the accumulation of PR’s as one measure of relative improvement, we see 52 PRs in April, 61 PRs in May, 105 PRs in June, and whopping 142 PRs in July. Comparing those numbers to the same period in 2017, we see 37 PRs in April, 46 PRs in May, 56 Ps in June, and 44 in July.
"In summary, prior to starting treatment her PR frequency was up only slightly over 2017 but following her Performance Lab sessions, her PR rate was 2x to 3x as much. When we take into account that she rode approximately 33% more miles in June and July of 2018 vs 2017, the PR rate drops to 1.5 to 2x which is still a very strong correlation. Moreover, Misti’s treatments occurred through early June yet her measured improvement in terms of PRs did not peak until July. The best hypothesis we have is that while her muscles were immediately firing better it takes much longer for other performance influencing aspects of her physiology and psychology to realign and realize maximum performance."
"Beyond the Strava data, I’ll add a few anecdotal comments of my own. Misti and I have been riding together for the better part of 20 years and we ride together several days a week. Over the past few months I have witnessed Misti riding not just faster but riding lines that she previously wouldn’t have even considered attempting. Her confidence seemed to soar and I watched as several lines that had been “in her head” were suddenly no problem. In this way, the Performance Lab seemed almost transformative for her. It appears that it didn’t just make her better at what she was already doing but opened her up to challenging lines that she would have never considered."
