Previous studies strongly have supported importance of aerobic capacity for 2000m rowing performance [1–3] and there are few studies that demonstrated anaerobic capacity had critical role in rowing performance [4–6]. The purpose of the present study is to investigate the relationship between 2000m rowing performance and anaerobic capacity, which were estimated by critical power (CP) model [7, 8] and by all-out tests of short duration as well. We also examined aerobic capacity.
Subjects and Methods
Nine male collegiate rowers (age:20.0 ± 1.0 yrs, height:174.5 ± 4.5 cm, weight:70.1 ± 7.5 kg) performed 1) incremental exercise tests to determine VO2max, 2) CP test (400m, 600m, 800m and 1000m), and 3) 2000m test. For each subjects, the amount of work (power×time) was plotted against exercise time. The CP was determined as the slope of the linear regression between the work and time. The anaerobic work capacity (AWC) was determined as the y-intercept of the linear regression. AWC was evaluated with standard error of estimation (SEE)  for the sake of accurate observation. If SEE of regression line was greater than 10 % of AWC, it was recalculated except one trial that had largest error.
These results are in accordance with the established interpretation by which contribution of aerobic capacity to rowing performance are well recognized [1–6]. However, our data suggest that anaerobic capacity estimated by AWC also have a pivotal role for rowing performance. Since CP and AWC are affected by familiarity of subject to intensive exercise  and physiological condition such as fatigue caused by consecutive training sessions, examination of anaerobic capacity might predict rowing performance more precisely in practical competitive situation.
