“…Multiple studies have been conducted [7,9,10,11,12] to obtain the physiological profiles (VO 2max , peak heart rate, VO 2peak , and peak blood lactate) of athletes across a variety of water-based sports. The devices used include cycle ergometers [9], treadmills [6,7,13], tethered swimming [7,9,10], swim flume [14], and swim ergometers [2,6,8,15]. VO 2max and VO 2peak results obtained utilizing cycle ergometers or treadmills for data collection in a surfing population lack specificity to surfing due to the sport’s dominance of upper body demands.…”
