Physiological determinants of peak power output in sprint cycling

There is a good understanding of determinants that influence performance in cycling such as air resistance, body mass and the positioning of the rider. Physiologists and biomechanists at the English Institute of Sport have been capturing high-resolution force-velocity and power data from a range of elite track cyclists that span a multitude of different training stimuli and performance for many years. One key physiological marker in track sprint cycling is peak power output (PPO). However, the specific physiological determinants that relate to PPO are not well understood and have only been limited to anthropometric studies, which have had conflicting results. Elite athletes typically experience a range of training stimuli, intuitively causing different adaptations to skeletal muscle depending on the different stimuli. It would therefore be interesting to investigate what are the underlying physiological adaptations during certain phases of strength and power training and how these stimuli affect the muscle architecture, neuromuscular system and more importantly, performance.
