1 The study of Barlow et al. [58] was based on 60 surfing sessions and 39 recreational surfers of varied ability.
2 This study was based on 85 surfing sessions by the same surfer, of an intermediate level according to the Hutt et al. [60] surfer skill rating scale.
3 The study of Barlow et al. [58] used an absolute cut-off speed of 2.5 m s−1, whereas in this study the cut-off was determined independently for each session by use of hinge functions.
