There was a significant difference overall in the change in testosterone levels over time between the different feeding protocols ( p < 0.001); the 5 h time period explained 16% of the variance ( p = 0 < 0.001), and the different feeding protocols explained a further 17% of the variance, with a feeding protocol x time interaction approaching significance; p = 0.053 ( Figure 1 ).
