Introduction: Energy expenditure associated with the agility to maneuver the wheelchair is poorly studied in the aerobic fitness field tests. Thus, the objective of this study was to compare the physiological responses and the end-test scores obtained from the octagon multistage field test by Vanderthommen et al. (2002) (MFT) [1] and the modified condition in “8 form” (MFT-8).

Method: Sixteen trained wheelchair basketball players (6.6±2.3 years training duration, 2.9±1.2 points according to international classification) performed both tests in randomized condition. The levels performed (end-test score), peak values of oxygen uptake (VO2peak), minute ventilation (VEpeak), heart rate (HRpeak), peak and relative blood lactate (Δ[Lact] = peak - rest values) and the perceived rating exertion (RPE) were measured.

Results: MFT-8 induced higher VO2peak and VEpeak values compared to MFT (VO2peak: 2.5±0.6 versus 2.3±0.6 L⋅min-1 and VEpeak: 96.3±29.1 versus 86.6±23.4 L⋅min-1; P < 0.05) with no difference in other parameters. Significant relations between VEpeak and end-test score were correlated for both field tests (P < 0.05). No significant difference was found between peakVO2 estimated by Vanderthommen regression [1] and measured VO2peak for MFT (29.6±4.2 mL⋅min-1⋅kg−1 versus 32.1±7.8 mL⋅min⋅kg−1). At exhaustion, MFT attained incompletely VO2peak and VEpeak.

Discussion: Among experienced wheelchair players, MFT-8 had no effect on test performance but generates higher physiological responses than MFT. In field test, subject movement in his wheelchair when changing direction would be to measure and could have an effect on breathing propulsion-coupling [2].
