简要总结
This study provides participants with two diets that vary in their glycaemic index values (low vs. high), whilst also measuring cognitive performance and mood.
详细描述
Therefore, the current study introduces cognitive testing into study procedures. Participants will consume the favourable and unfavourable conditions (each containing three meals) on separate days following a crossover, randomised, couterbalanced design. The primary dependent variable is cognitive function, whilst secondary measures include glucose and mood. It is hypothesised that the favourable meal profile will be associated with cognitive and physiological benefits relative to the unfavourable meal profile.

主要结局
Change in cognitive performance between time points assessed
时间窗: This was tested 9 times a day, with two days, giving a total of 18 times. Each battery of four tasks lasted approximately 15 minutes
A participants performance over four cognitive tasks
次要结局
- Glycaemic profile(This was measured 23 times a day, for two days, giving a total of 46 times)
- Sleepiness(This takes approximately 30 seconds to complete. Participants were tested six times a day. There were two test days. Giving a total of 12 times, or approximately 6 minutes overall.)
- Fullness(This takes approximately 30 seconds to complete. Participants were tested six times a day. There were two test days. Giving a total of 12 times, or approximately 6 minutes overall.)
- Mood (alertness, anxiety and contentment) using the Bond-Lader (1974) Visual Analogue Scale(This takes approximately 5 minutes to complete. Participants were tested six times a day. There were two test days. Giving a total of 12 times, or approximately 60 minutes of mood scale completion.)
- Hunger(This takes approximately 30 seconds to complete. Participants were tested six times a day. There were two test days. Giving a total of 12 times, or approximately 6 minutes overall.)
