PURPOSE: The purpose of this study was to determine the energy expenditure of stand up paddleboarding (SUP) and performance variations among board designs. METHODS: 24 male and female participants (23 + 6 yrs, 179 + 10 cm, 75 + 11 kg, 13 + 8% body fat) completed the study. In the laboratory, participants performed three stages of increasing intensity on a paddleboard ergometer, measuring heart rate, watts, VO2, and VCO2, via a metabolic cart. Participants reported to the river for an initial field trial, which consisted of three time trials on a river (R), touring (T), and inflatable (I) paddleboard using a randomized crossover design. Time to complete the trials was measured, and heart rate was used to estimate VO2. On a separate visit, participants performed a 5-minute steady-state trial using Douglas Bags to measure VO2, VCO2, and VE.RESULTS: A significant relationship (r2=0.72, p2 during laboratory testing, y=0.012x + 0.939. Time to complete the trials was less for R and T boards compared to I board (6.0 + 1.3, 5.9 + 1.2, and 7.0 + 1.4, respectively, p2 (L) during the course was less for R and T compared to I (12.0 + 3.1, 11.9 + 3.1, and 13.7 + 4.0, respectively, p2=0.89, p2, y=0.9801x – 0.0429. CONCLUSION: These data demonstrate that board design and hydrodynamic profile contribute to paddling speed during SUP. The energy demand of SUP is comparable to moderate rowing, canoeing, kayaking, and vigorous swimming and substantiates SUP as an effective form of aerobic exercise.
