Effects of age, training background and duration of running on abnormal urinary findings after a half-marathon race

Abstract

The effects of such mineral ion manipulation upon muscle water content are further supplemented by glycogen depletion (pushed to a state of 'borderline ketosis', as an initial allowance of 92 g day-1 is tapered to 23 g day-' over the period 7-4 days before competition), with a final period of 'supercompensation', when 10 separate 40-g carbohydrate meals are taken at 90-min intervals. The sources of carbohydrate are limited to items such as bananas, raisins, dates, yams, tomatoes, apricots and peaches, the objective being to maximize the intake of potassium, and to minimize the intake of sodium. If the muscles still appear 'flat' on the day before competition, the intake of these carbohydrates is further boosted to 40gh-1. Protein (lgkg-1 of body mass) is taken as dry curd, with the objective of further minimizing sodium intake.
