What are the specific mechanisms by which smoking impairs cycling-related muscle function and strength, and to what extent can even moderate smoking habits impact athletic performance in cyclists? Are there certain muscle groups or physiological systems that are more susceptible to the negative effects of smoking, and can these effects be reversed or mitigated through smoking cessation and training? How do smoking-related declines in cardiovascular function, such as reduced aerobic capacity and increased peripheral resistance, intersect with muscle function and strength in cycling, and are there any data on the impact of smoking on muscle damage and recovery in cyclists?
