Michaud3 1Montana State University – Bozeman, MT, USA; 2University of Minnesota – Duluth, MN USA; 3US Paralympics Nordic Skiing and Crosscut Mountain Sports Center Elite Team – Bozeman, MT USA Para cross-country skiing and para biathlon – collectively referred to as para Nordic – are sports that have been Paralympic events since 1976 and 1988, respectively. PURPOSE: Given the complete lack of published VO2MAX testing protocols reported in the literature for para Nordic athletes, the purpose of this pilot study was to document the development of treadmill-based roller skiing graded exercise test (GXT) protocols for para Nordic athletes. METHODS: 3 women and 5 men (Mean±SD: 22±3 yrs age), including 3 sit (LW 12 disability classifications) and 5 standing (4x LW 8; 1x LW 5-7) skiers, volunteered and were training with the U.S. Paralympics Nordic Skiing Team at the time of testing. First, skiers warmed up roller skiing for 10-20 mins on an oversized treadmill (2.44 m wide x 3.05 m long belt size) using either skate roller skis (standing skiers) or roller skis mounted to their sit-ski buckets (sit skiers). Skiers were protected from falls with an overhead harnessing system during warm-up and testing periods. The GXT protocol, which was modelled after a protocol used with able-bodied skiers, started with the treadmill at a fixed grade (2-4%) and then increased in speed by 0.8 KPH (0.5 MPH; variable starting speed 6.4-8.0 KPH) for each stage until “threshold”, after which speed dropped by 0.8 KPH and grade increased by 1.0% for each stage until volitional exhaustion. Without metabolic testing, test success was based upon satisfying at least 2 of 3 criteria: 1) HRMAX ≥95% age predicted HRMAX; 2) Immediate post-blood lactate ≥8.0 mmol/dl. 3) RPE ≥9 (0-10 scale). With metabolic testing, test success was based upon satisfying at least 3 of 4 criteria: Same first two criteria; 3) RER≥1.15; 4) VO2 “plateau”. RESULTS: For the tests without metabolic testing, 2 satisfied all 3 criteria, 1 ...
