FS

Sessions 1–3

2.6 ± 0.8

Affective valence (i.e. pleasure-displeasure) was assessed using the single-item, 11-point Feeling Scale [44]. The FS uses a bipolar scale and ranges from – 5 ‘very bad’ to + 5 ‘very good’, with anchors designated for 0 (neutral) and all odd integers in-between.

Sessions 4–7

Average

1.9 ± 0.6

RPE

Sessions 1–3

12.7 ± 2.1

Exercise exertion was monitored using a rating of perceived exertion using the 15-point Borg scale [45]. The scale ranges from 6 ‘no exertion’ to 20 ‘maximal exertion’ with anchors designated for all the odd integers in-between.

Sessions 4–7

EES

Sessions 1–3
