摘要: Purpose: This study compared the metabolic and performance effects of riding front-only suspension (FS) front-and-rear (FRS) mountain bicycles on an off-road course that simulated competitive cross-country race conditions (>105 min in duration, with ∼70% time spent uphill). Methods: Seven bikers (73.8 ± 7.6 kg; 61.0 4.3 mL·kg–1·min–1) completed two randomized FS FRS trials. Bikes were similar, excluding rear wheel FRS, which increased bike weight by ∼2 kg. Each trial consisted four laps rugged 8 km trail 154 m elevation gain per lap. The first three performed at VO2max; VO2, HR, RPE collected during third laps. final lap was as a maximal time-trial effort. Results: During laps, similar between FRS. However, significantly faster than ascending segment (17.6 2.9 vs 18.9 3.4 min, P = ...
