Carbohydrate ingestion and feel-good responses in recreational exercisers
Carbohydrate (CHO) intake, especially ‘sugary’ sports drinks, is perceived to be detrimental for health and weight management. However, CHO is an important macronutrient for energy provision during exercise, as well as fuel for the central nervous system. Therefore, CHO intake is a well known performance-enhancing ergogenic aid. In addition, CHO is also known to influence mood and lead to more pleasurable feelings during exercise. ‘Spin’ classes are becoming increasingly popular group-fitness cycling sessions where participants work at self-selected exercise intensities. CHO supplements may allow these recreational exercisers to increase energy expenditure during exercise, enhance their ‘affect’, mood and improve health and fitness parameters. Therefore, this study will examine the influence of CHO intake during 2-3 x 45-min spin classes per week, over a 10-week intervention period, on health and fitness parameters in recreational exercisers.
