dc.description.abstractTo compare the effects of test protocols with different increments in workload and duration on peak oxygen uptake (V̇ O2peak), and related physiological parameters during seated upper-body poling (UBP). Methods: Thirteen upper-body trained, male individuals completed four UBP test protocols with increments in workload until volitional exhaustion in a counterbalanced order: 20W increase/every 30s, 20W/60s, 10W/30s and 10W/60s. Cardio-respiratory parameters and power output were measured throughout the duration of each test. Peak blood lactate concentration (bLapeak) was measured after each test. Results: The mixed model analysis revealed no overall effect of test protocol on V̇ O2peak , peak minute ventilation (VEpeak), peak heart rate (HRpeak), bLapeak, (all p ≥0.350), whereas an overall effect of test protocol was found on peak power output (POpeak), (p=0.0001), respiratory exchange ratio (RER) (p=0.024) and test duration (p<0.001). There was no difference in POpeak between the 20W/60s (175±25W) and 10W/30s test (169±27W; p=0.092), whereas POpeak was lower in the 10W/60s test (152±21W) and higher in the 20W/30s test (189±30W) compared to the other tests, (all p=0.001). In addition, RER was 9.9% higher in the 20W/30s- compared to the 10W/60s test protocol, (p=0.003). Conclusions: The UBP test protocols with different increments in workload and duration did not influence V̇ O2peak and can therefore be used interchangeably when V̇ O2peak is the primary outcome. However, POpeak and RER depend upon the test protocol applied and the UBP test protocols can therefore not be used interchangeably when the latter are primary outcome parameters.en
