‘Priming’ exercise and O2 uptake kinetics during treadmill running

Abstract: We tested the hypothesis that priming exercise would speed kinetics during treadmill running. Eight subjects completed a square-wave protocol, involving two bouts of treadmill running at 70% of the difference between the running speeds at lactate threshold (LT) and max, separated by 6-min of walking at 4 km h −1 , on two occasions. Oxygen uptake was measured breath-by-breath and subsequently modelled using non-linear regression techniques. Heart rate and blood lactate concentration were significantly elevated … Show more

“…In order to determine the time needed to achieve VO 2max , mathematical adjustments were made to analyze VO 2 kinetics during the Tlim using mono-exponential functions as suggested by Jones et al (2008) and described in the following equation:…”

“…However, previous research has employed both low and high intensity cycling protocols prior to 260 running and have reported little or no significant change to muscle recruitment patterns (Bonacci et al, 2011). Similar evidence has stated that prior submaximal or moderate intensity exercise is not sufficient to influence subsequent physiological variables, including the speeding of V O 2 (Gerbino, Ward, & Whipp, 1996;Jones et al, 2008). Our results show that V O 2 values at t 1/2 and MRT are significantly 265 reduced in time (Table 3) and are likely due to the elevated metabolic starting point during the C-R condition.…”

“…Potentially, this could impact upon our proposed TRIMPS score particularly for the determination of v max . Priming exercise, however, seems to be specific to the exercise modality and has not been found in running (Jones et al 2008). On this evidence we feel that, for running at least, our TRIMPS score should be sufficiently robust, however, it would be prudent to ensure that no exercise in the very heavy domain is used prior to the trials to establish the speed-duration relationship.…”
