This study aimed to 1) analyse the effect of the pedalling activity in different 4-min time trials (TT4) (laboratory and field conditions) and 2) make the comparison between TT4 and MAP determined from the classical incremental exercise test in laboratory. It was hypothesized that the exercises performed on the field would determine higher physical (PO) and mental (AL) involvements due to different environmental conditions.Sixteen male cyclists underwent an incremental test to exhaustion and three TT4 under different conditions: cycle ergometer (CE), level ground (LG), and uphill (UP).Correlation was observed for PO with a trivial effect size and narrow limits of agreement (LoA) between MAP and CE TT4 (r = 0.96, p < 0.001). The comparison between the CE, LG, and UP tests indicates that PO was significantly higher in UP compared with CE (+8.0
