Resumen
The purpose of this study was to test the hypothesis that surfers would achieve a higher V[Combining Dot Above]O2peak when tested in a swim flume vs. on a swimbench ergometer. Forty-eight surfers (male: 38, female: 10) aged 18-45 years participated in the study. Protocol 1 and 2 both measured heart rate, oxygen consumption (V[Combining Dot Above]O2), and respiratory exchange ratio while subjects performed an incremental paddling test both on a swimbench ergometer and in a swim flume. Protocol 2 additionally measured muscle activity and changes in skin temperature. V[Combining Dot Above]O2peak was significantly higher in the swim flume (33.03 +/- 1.04 ml[middle dot]kg-1[middle dot]min-1) vs. on the swimbench ergometer (29.86 +/- 1.08 ml[middle dot]kg-1[middle dot]min-1) (p value < 0.001). There were also significant differences in muscle activation and changes in skin temperature between the flume and ergometer (p-value < 0.05). Surfers significantly increased their V[Combining Dot Above]O2peak in the water suggesting previous reports of V[Combining Dot Above]O2peak likely underestimated surfer's aerobic fitness when measured on a swimbench ergometer. Future research investigating the aerobic fitness of surfers should be conducted while paddling in water or account for the 11% difference in V[Combining Dot Above]O2peak when tested on a swimbench ergometer.
