RELATIONSHIP BETWEEN PHYSIOLOGY AND PERFORMANCE OF HANDCYCLING IN ABLE-BODIED SUBJECTS

Introduction
Incremental step tests and sprint tests with lactate measurements are commonly used in handcycling diagnostics. However, it is still unclear if the physiological parameters elucidate the athlete’s performance characteristics. Therefore, the aim of this study was to analyze the relationship between physiological and performance measures under laboratory conditions in handcycling.
Methods
Twelve able-bodied triathletes without handcycling experience performed an initial familiarization protocol. The tests were performed in a racing handcycle that was attached to an ergometer. Following the familiarization, a 15s-All-Out sprint test was performed in which the peak power output (POmax,AO15) and the glycolytic rate (V̇Lamax) were determined. Additionally, the participants performed an incremental step test. At the end of every stage, lactate concentration, heart rate and perceived exertion were collected. Out of the step test, the maximal achieved power output (POmax,ST) and the interpolated lactate threshold (PO4mmol) were calculated. Power values were correlated among each other and with the alactic time (talac), the maximal lactate concentration after the sprint test (Lamax,AO15), the maximal heart rate during the step test (HRmax,ST), the V̇Lamax, and the maximal lactate concentration during the step test (Lamax,ST).
Results
POmax,AO15 was significantly correlated with V̇Lamax (r = 0.604, p = 0.037). POmax,ST was significantly correlated with PO4mmol (r = 0.577, p = 0.060), Lamax,AO15 (r = -0.680, p = 0.015) and V̇Lamax (r = -0.649, p = 0.022). PO4mmol was significantly correlated with Lamax,ST (r = -0.605, p = 0.037).
Discussion
The significant correlations indicate that anaerobic and aerobic performance measures in handcycling are related to their physiological equivalents. The usage of physiological measures in diagnostics seems to be promising for developing performance and the examination of different training regimes. Future research should replicate this study with elite athletes.
