ABSTRACT

The purpose of this study was to develop a simple dryland test that could be used to measure the anaerobic power of competitive swimmers. Sixteen well trained swimmers (17±1 years) completed a series of four submaximal and one maximal effort swims for determination of swimming economy. A linear relationship (V̇O2 vs velocity) was extrapolated to 110% of V̇O2max for each swimmer. Within seven days swimmers completed a freestyle swim at this pace for an average of 3.36 ± 0.20 min. During this time, oxygen uptake was measured continuously, accumulated O2 uptake was determined at 10 s increments and O2 deficit (anaerobic capacity) calculated (Hermansen and Medbø, 1984). A blood sample was taken 2 min post-swim for analysis of lactate. A 45 s maximal effort test was also administered using an isokinetic swim bench for determination of total muscular work, average power and force (last 5 s of the bout), and a fatigue ratio (percent decline in power from the first to last 5 s increment). The data revealed significant correlations between the O2 deficit swim and the swim bench test. It is suggested that a 45 s maximal effort test on the swim bench can be used as an accurate way of measuring and predicting a swimmer’s anaerobic profile.
