Carbohydrate Feeding Frequency, Muscle Glycogen and Exercise Capacity in Runners

The Effect of Carbohydrate Feeding Frequency on Muscle Glycogen and Exercise Capacity in Runners

The aim of this study is to investigate the effects of regular sucrose feeds compared to a single large bolus given late in exercise, on muscle glycogen utilisation, exercise capacity and other markers of metabolism during running

• Be willing to have the necessary samples taken during the testing protocols
• Not a habitual smoker
• Have the capacity and willingness to provide informed consent (oral and written)
• Successful completion of the physical activity readiness questionnaire (PAR-Q)

Exclusion Criteria:

• Female
• <18 or >50 years old
• Not regularly participating in running activity (<3 times a week)
• Experience contraindications to the administration of the proposed anaesthetic (Lidocaine Hydrochloride)
