Association between anaerobic components of the maximal accumulated oxygen deficit and 30-second Wingate test

The purpose of this study was to analyze the relationship between the anaerobic components of the maximal accumulated oxygen deficit (MAOD) and of the 30-second Wingate anaerobic test (30-WAnT). Nine male physical education students performed: a) a maximal incremental exercise test; b) a supramaximal constant workload test to determine the anaerobic components of the MAOD; and c) a 30-WAnT to measure the peak power (PP) and mean power (MP). The fast component of the excess post-exercise oxygen consumption and blood lactate accumulation were measured after the supramaximal constant workload test in order to determine the contributions made by alactic (AL_MET) and lactic (LA_MET) metabolism. Significant correlations were found between PP and AL_MET (r=0.71; P=0.033) and between MP and LA_MET (r=0.72; P=0.030). The study results suggested that the anaerobic components of the MAOD and of the 30-WAnT are similarly applicable in the assessment of AL_MET and LA_MET during high-intensity exercise.

Aerobic profile of climbers during maximal arm test

This study compared measurements of upper body aerobic fitness in elite (EC; n=7) and intermediate rock climbers (IC; n=7), and a control group (C; n=7). Subjects underwent an upper limb incremental test on hand cycle ergometer, with increments of 23 W · min(-1), until exhaustion. Ventilation (VE) data were smoothed to 10 s averages and plotted against time for the visual determination of the first (VT1) and second (VT2) ventilatory thresholds. Peak power output was not different among groups [EC=130.9 (±11.8) W; IC=122.1 (±28.4) W; C=115.4 (±15.1) W], but time to exhaustion was significantly higher in EC than IC and C. VO(2 PEAK) was significantly higher in EC [36.8 (±5.7) mL.kg(-1).min(-1)] and IC [35.5 (±5.2) mL.kg(-1).min(-1)] than C [28.8 (±5.0) mL.kg(-1).min(-1)], but there was no difference between EC and IC. VT1 was significantly higher in EC than C [EC=69.0 (±9.4) W; IC=62.4 (±13.0) W; C=52.1 (±11.8) W], but no significant difference was observed in VT2 [EC=103.5 (±18.8) W; IC=92.0 (±22.0) W; C=85.6 (±19.7) W]. These results show that elite indoor rock climbers elicit higher aerobic fitness profile than control subjects when measured with an upper body test.
