What are the current understandings and research findings on the impact of shorter cranks on muscle firing sequences in Zone 2, and how do these changes affect the overall efficiency and effectiveness of a riders pedaling technique?
Specifically, Im interested in knowing whether the use of shorter cranks can alter the activation patterns of the primary movers, such as the quadriceps, hamstrings, and glutes, and if so, how these changes influence the riders ability to maintain a consistent power output and cadence in Zone 2.
Additionally, are there any notable differences in the muscle firing sequences between riders with varying levels of experience, fitness, and pedaling technique when using shorter cranks in Zone 2, and if so, what are the implications for coaches and riders looking to optimize their training and performance?
Furthermore, how do the changes in muscle firing sequences with shorter cranks in Zone 2 affect the riders overall energy expenditure, fatigue, and perceived exertion, and are there any potential benefits or drawbacks to using shorter cranks for riders who spend a significant amount of time in this intensity zone?
Lastly, what are the limitations and future directions of current research on this topic, and what are the key areas that require further investigation to fully understand the impact of shorter cranks on muscle firing sequences in Zone 2?
