BP4 Shows The Proof is In The Pudding

The data  in the link(see big orange results button) shows a comparison of ten cyclist using standard “tops” position vs BP4 position. The workloads are identical, performed on a calibrated Velodyne Ergometer using the subjects own bikes. A medical grade SensorMedics Vmax metabolic cart was calibrated before each assessment and used to collect the metabolic data. Each workload was 5 minutes long and is used in the spread sheet below for rider comparisons. The two VO2 test for each rider were performed one week apart at the same time of day using the same training volume and diet for each week prior to testing. As can plainly be seen, the BP4 position was beneficial for 6 out of the 10 riders in this experiment. This may or may not seem to be a huge win for us, but consider what the position of the rider was. Each participant rode on a flat grade in a lab. No wind, no changes in incline or decline. All we did was change the angle of the hands on the tops. Under those conditions, it was not expected that we would  have much of a change in rider physiological response, but as one can see from the tabulated breakdown, 6 of the riders had a better VE and some had a better VO2. A better VO2 from changing hand position? That’s crazy, but it’s true. What is not seen in these results were the riders feedback about how they felt while riding in the…
