“all-out” Tethered Running as an Alternative to Wingate Anaerobic Test

An “all-out” tethered running on the treadmill represents an alternative form of exercise used for the assessment of anaerobic capacity. Contrary to the well known and frequently used “all-out” test on the cycle ergometer (Wingate anaerobic test), there is a lack of information concerning the parameters of anaerobic capacity obtained from tethered running on the treadmill. The aim of our study was therefore to compare the parameters of anaerobic capacity (maximal and mean power, fatigue index, and blood lactate concentration) in 30-second “all-out” tests performed on the isokinetic cycle ergometer and in the form of tethered running on the treadmill, respectively. The subjects underwent in random order in two different days a period of 30second “all-out” cycling on the isokinetic ergometer at a revolution rate of 100 rpm and tethered running on the treadmill at a velocity of 13 km/h. Analyses of the results showed that tethered running and isokinetic cycling did not differ significantly either in maximal or mean power. However, the fatigue index and blood lactate were significantly higher in tethered running than in isokinetic cycling. Taking into account the similar values of maximal and mean power production between the exercise modes examined it may be concluded that the 30-second “all-out” tethered running on the treadmill represents an acceptable alternative for the assessment of anaerobic capacity. However, in comparison with isokinetic cycling slightly higher values of fatigue index and blood lactate have to be expected.
