FTP20 Test Review
The first review, "What is known about the FTP 20 test related to cycling? A scoping review," revealed there are only a few studies that have looked at the 20-minute test of FTP. The protocols of the different studies varied a lot, so it is difficult to find significant trends.
Overall, this is a thorough analysis of the 20-minute FTP test and how well it predicts/correlates with other measures. For example, it has decent correlation with MLSS and LT2, but shouldn’t replace them.
Interval Protocols and Time Near VO2max
In the next study, "Time Spent Near VO2max During Different Cycling Self-Paced Interval Training Protocols," the researchers compared 4-minute and 8-minute self-paced intervals with 4:1 and 2:1 recovery ratios. The findings suggest the 2:1 ratios tended to result in more time near VO2max.
But it raises a question: Is time near VO2max the goal? The assumption is that time at VO2max is better for adaptations. Does this assumption drive bad training practices?
Finally, this study also raises interesting questions about self-paced vs. set intensity intervals.
Inclusion of Sprints in Transition Period
The final study, entitled "The Inclusion of Sprints in Low-Intensity Sessions During the Transition Period of Elite Cyclists Improves Endurance Performance 6 Weeks Into the Subsequent Preparatory Period," looked at whether having some intensity in the transition period will help a subsequent preparation period. The findings suggest that including sprints improved 20 minute all-out TT, but there is still a question of whether there is a physiological benefit.
The test procedure was huge; there were differences between the groups. All that improved was their ability to ride at a higher percent of VO2max. Is it a simple improvement in an athlete's ability to suffer?
