Experimental Approach to the Problem
The WAnT has previously been used as test by which RSA
protocols are validated (2,30). It is therefore necessary to
determine whether bothWAnT performance and physiological
responses are indeed related to the repeated sprint-type
efforts that might be expected during match play. If both the
performance and physiological responses of the RAST display
agreement with those of the WAnT, the RAST could
therefore be used as a suitable replacement to the WAnT
for assessing anaerobic fitness
while incorporating running
locomotion and repeated sprint
movement, characteristics that
are inherent to most team
sports. In this regard, the
present study tested whether
there would be a relationship
between physiological and
analogous performance variables
obtained from both RAST
and WAnT protocols using
collegiate-level soccer players.
Measurements of V̇O2, blood
lactate (BL), and heart rate
(HR) were used to examine
the physiological differences
and relationships between protocols,
and PP and MP were
used to examine performance
relationships.
