α, β,γ,δ: studies based on the same trial; ø: variables reported with inconsistent data among articles from the same trial.
As trial results are described in more than one paper, the bolded study represents the first published paper from a given exercise trial.
*statistically significant from baseline.
†statistically significant from control group.
‡statistically significant from comparison group(s).
§statistically significant from 4 months.
