The tests themselves were hard, but nothing compared to the <a title=\"Lab test potions\" href=\"https:\/\/www.alananna.co.uk\/blog\/2010\/potions-for-lab-tests\/\">disgusting potions<\/a> I had to drink beforehand &#8211; For that reason alone I&#8217;m glad that they are over!<\/p>\n<p>I met Jon yesterday for a quick synopsis of what he thinks the test have shown, and some finally tests to calibrate my work rates with my heart rates so that I can devise some effective training routines. It also gave us a chance to compare my performance with the similar tests done in a previous experiment I did for Jon about a year ago.<\/p>\n<p>I won&#8217;t go into the results that Jon noticed as I&#8217;m sure he wants to keep those to himself until he&#8217;s published his thesis, but it was reassuring that my performance had improved.<\/p>\n<p>The first thing of note was that I&#8217;d lost about 3kg in weight. That&#8217;s good and as long as my power outputs had remained the same that should mean that I&#8217;d be a little bit faster. Last year, my Critical Power (CP) was 251 Watts, this year it had increased by about 10% to 275 Watts.<\/p>\n<p>Now, Critical Power doesn&#8217;t really mean that much as it is defined as the the maximum sustainable power output you can maintain for a given  amount of time. So, your CP for 1 min will be very much higher than it is for 30 minutes. The CP measurements above are based on a ramp test that I did prior to the lab tests and should be a CP figure for around 30 minutes. Whilst doing the tests yesterday, the 275 Watt setting wasn&#8217;t uncomfortable and it did feel as though i;d be able to sustain it for a good 20-30 minutes. Maybe a little longer if needed.<\/p>\n<p>So, it was good news all round &#8211; A decrease in weight and an increase in power means that my power-to-weight ratio is a fair bit higher than it was. This should in theory equate to me being faster on the bike, especially up the hills. I certainly felt OK on last nights ride.<\/p>\n<p>I guess really I should aim for a similar amount of improvement by this time next year. If I could lose another 3-4kg and increase my CP to 300 Watts I&#8217;d be pretty happy.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>My recent lab tests with Jon at the Sports and Exercise Science Department are finally over.
