Although many scientific research studies have looked at the physiological profiles of traditional sport athletes, little scientific research has been done on extreme sport participants, in particular, elite bicycle motocross (BMX) freestyle riders. The purpose of this study was to look at the physiological profiles of BMX freestyle riders. Seven men (age 25.85 ± 1.86 yrs, height 173.44 ± 6.20cm, mass 76.51 ± 8.53kg) with at least 3 years of professional BMX freestyle riding experience participated in the study. Tests performed included cardiovascular endurance (on a cycle ergometer), flexibility (sit-and-reach), muscular strength, (one-repetition maximum bench press, isometric pull, and grip strength with hand dynamometer), lower limb power (vertical jump), anaerobic power (Wingate test), and body composition (3-site skin-fold test). The results indicate that BMX freestyle riders exhibited similar fitness characteristics to that of other elite athletes, such as wrestlers, soccer players, and baseball players, and were above average in overall fitness when compared to the male general population ages 20–29. Findings showed that the BMX riders lacked in upper body strength, and lower limb power when compared to elite football, baseball, and basketball players indicating possible areas for improvement in their training programs.
