What specific wattage metrics should cyclists focus on to improve cornering, and how can they effectively integrate these metrics into their training to optimize cornering performance? For instance, should riders prioritize peak wattage, average wattage, or wattage variability during cornering exercises? Additionally, how can cyclists utilize wattage data to identify and address specific cornering inefficiencies, such as excessive braking or acceleration, and what role do factors like bike setup, tire pressure, and rider positioning play in this context? Furthermore, can wattage data be used to inform cornering technique decisions, such as when to adopt a more aggressive or defensive line through a turn, and how can riders balance the need for high wattage output with the need for control and precision during cornering? Finally, are there any cutting-edge training methods or technologies that cyclists can leverage to take their cornering performance to the next level using wattage data, and what are the key takeaways from recent research on the relationship between wattage and cornering performance in cycling?
