Nutritionist Monique Ryan answers some more questions about the effects of cycling on bone density.
It is not unusual during a full season of racing to hear about a pro cyclist or two breaking a clavicle or other bone in a multi-rider pile-up. But is there something inherent to cycling that increases your risk for developing a break when you hit the pavement hard?

Osteoporosis prevention and treatment has long focused mainly on women. It is true that men build larger and stronger bones early in life and are less likely to develop this disease, which is characterized by less dense, brittle bone mass more susceptible to fracture. Yet according to the National Osteoporosis Foundation, two million men currently have osteoporosis and another 12 million with low bone mass are at risk. Clearly a focus on prevention is also important for men, and osteoporosis is likely underdiagnosed in this gender and certainly not as extensively studied. There are many steps
Dear Monique,In your April 25th column (More prepping for long rides), you mentionweighing before and after a ride. Is the weight differential entirely fluidor food in the stomach? Can you say a bit more about this differential?Should riders shoot for some change, no change, under what circumstances?Thanks,JoelHi Joel,The difference between your weight before and after a training riderepresents the amount of sweat that you did not replace with fluid intakeduring the ride.

Dear Monique:What is your opinion regarding the effect of sodium phosphate loadingon cycling performance for a time trial?Thanks,LKDear LK;Sodium phosphate is a phosphate salt, and phosphate salts can playan important role in metabolism at it relates to sports performance. Phosphatesalts may buffer lactic acid and produce energy via the oxygen energy system-and consequently enhance performance during aerobic endurance activities.The important questions regarding the use of phosphate salts are the following.Does the research support that phosphate salt loading actually improvesperformance?
