Figure 2. Changes in the acute Exercise Enjoyment Score (possible score 1-7) (mean ±sd) measured prior to (top), during (middle) and after (bottom) training bouts (all measurements on the same day within subjects) in relation to the type of training and the duration of the study (circles=steady state, triangles=Meyer, Squares=Tabata). Notably, the ESS is generally declining across the course of the study, and the most intense training scheme (Tablata) was rated the least enjoyable.
