Here are some results from the testing. Look them over carefully to see in what ways improvements were made and in what ways we failed to improve, or maintain improvement.
Skier A:
May 2005 | May 2006 | October 2005 | October 2006 | ||||
MPH | Lactate | MPH | Lactate | MPH | Lactate | MPH | Lactate |
8 | 2.40 | 8 | 1.92 | 8 | 0.64 | 12 | 0.96 |
13 | 4.28 | 16 | 3.88 | 17 | 4.96 | 18 | 4.52 |
Here notice the increase in speed at similar lactates. Also notice the improvement from year to year even from May to May, but also from October to October.
Skier B:
October 2005 | May 2006 | October 2006 |
Work at 1mmol | Work at 1mmol | Work at 1mmol |
11mph | None | 12.1 mph |
Work at 4mmol | Work at 4mmol | Work at 4mmol |
16.2 mph | 15.9 mph | 18.7mph |
This is another way to see something similar. The work this skier does is the speed. At 1mmol the skier could ski at 11mph last October. This May this skier could not ski at 1mmol. This is a decrease in low end fitness. However in October this year this skier could ski at 12.1mph at 1mmol lactate.
At threshold last October this skier was skiing 16.2mph. This October this skier was skiing 18.7mph. This skier did the max portion of the test at 18mph since they didn’t reach threshold until over 18mph (skier eventually got up to 20mph). In Oct 2005 this skier did the max portion at 16mph.
Skier C:
October 2005 | October 2006 | ||
MPH | Lactate (mmol) | MPH | Lactate (mmol) |
8 | 1.00 | 10 | 0.64 |
12 | 1.38 | 12 | 0.80 |
16 | 2.96 | 16 | 1.20 |
18 | 4.88 | 18 | 2.32 |
20 | N/A | 20 | 6.12 |
Here is an example of improvement from one year to the next at all intensities. Note the speeds and lactates. This skier (like skier B) also passed through threshold at high 18mph and made it through a stage at 20mph.
This protocol has been used by other teams for many years without this difficulty, but we have truly maxed out this test. By reaching 20mph and even 16mph we are starting to tax a skier’s neuromuscular ability at such a level that they cannot reach their cardiovascular limits. We have learned a lot about the skiers up through threshold but over a short period of time (2 years) they have outgrown this protocol and where we were learning more at above threshold intensities last year this year we were not successful at learning much over threshold – and so we must change our testing methods. Boo-yah.
Things we have learned.
Train hard, rest well and enjoy the process.
