As can be seen in Table
2, the anthropometric characteristics of the cyclist (188 cm, 81 kg) were different from those of Merckx (184 cm, 72 kg) and Moser (182 cm, 76 kg), who broke the world record in the past, but even more different from recent world record holders like Rominger (175 cm, 65 kg) and Boardman (177 cm, 69 kg). The morphotype of the latter two cyclists confers them relatively small FA values of 0.3220 and 0.3342 m2, respectively. These result in very low
C x values, which could explain to a great extent the elevated record speeds attained by these cyclists, i.e., 55.291 km/h by Rominger and 56.375 km/h by Boardman. Indeed, aerodynamic efficiency is a performance-determining variable at speeds above 50 km/h (
15,
25). The FA value of the subject in this study (0.3755 m2) represents 18.1% of his BSA, which agrees with previous reports that consider FA to be a constant fraction of BSA (
12). The present values are also in keeping with those observed by Swain et al. (
45) for riders with similar physical characteristics (0.378 m2 and 17.8% of BSA), but slightly lower than values reported by Capelli et al. [0.393 m2 and 20% (
4) and 0.42 m2 and 22% (
5)] and Sjøgaard et al. [25% of BSA (
43)].
