Reliability of the Maximal Lactate Accumulation Rate in Rowers
Int J Sports Med DOI: 10.1055/a-2206-4959The maximal lactate accumulation rate (VLamax) has been linked to lactic
anaerobic performance. Hence, accurate and reliable assessment is crucial in
sport-specific performance testing. Thus, between-day reliability data of
rowing-specific VLamax assessment was examined. Seventeen trained rowers (eight
females and nine males; 19.5±5.2 yrs;
1.76±0.08 m; 70.2±8.9 kg;
V̇O2max: 54±13 ml/min/kg)
performed 20-s sprint tests on two separate days (one week apart) on a rowing
ergometer. VLamax, peak lactate concentration, time to peak lactate, and mean
rowing power were measured. Good to excellent intraclass correlation
coefficients (ICCs), low standard error of measurement (SEM), and acceptable
levels of agreement (LoAs; 90% confidence interval) for VLamax
(ICC=0.85; SEM=0.02 mmol/L/s;
LoA±0.09 mmol/L/s), peak lactate
(ICC=0.88; SEM=0.3 mmol/L;
LoA±1.4 mmol/l), time to peak lactate (ICC=0.92;
SEM=0.1 min; LoA±0.5 min), and mean rowing power
(ICC=0.98; SEM=3 W; LoA±39 W) were
observed. In addition, VLamax was highly correlated (r=0.96;
p≤0.001) to rowing power. Thus, VLamax and sprint performance
parameters can be measured highly reliably using this sport-specific sprint test
in rowing. [...] Georg Thi...
