To find a subject and to understand the sentence clearly "As this goes along with an increase in α1-power and is supported by the fact that the perception of positive mood marginally missed significance in the post-exercise measurement, one might speculate that a low intensity run seems to have the most positive effect." Hello, everyone. 1. I am not sure what is a subject in this sentence for "... is supported by the fact that...". Maybe the whole part which comes before that? In other words, "Concurrence in an increase in α1-power is supported by...". Or only "an increase in α1-power"? In other words, " An increase in α1-power is supported by...". 2. to understand the meaning concerning "the fact". "the fact that the perception of positive mood marginally missed significance in the post-exercise measurement" It means that there was not a significance in post-exercise test regarding the perception of positive mood. Is it right? Thank you in advance!
