Active and Passive Recovery and Acid-Base Kinetics Following Multiple Bouts of Intense Exercise to Exhaustion

Abstract

The purpose of this study was to profile the effect of active versus passive recovery on acid-base kinetics during multiple bouts of intense exercise. Ten males completed two exercise trials. The trials consisted of three exercise bouts to exhaustion with either a 12 min active (20% workload max) or passive recovery between bouts. Blood pH was lower in the passive (p) recovery compared to active (a) throughout the second and third recovery periods [second recovery: 7.18 +/- 0.08 to 7.24 +/- 0.09 (p), 7.23 +/- 0.07 to 7.32 +/- 0.07 (a), P < 0.05; third recovery: 7.17 +/- 0.08 to 7.22 +/- 0.09 (p), 7.23 +/- 0.08 to 7.32 +/- 0.08 (a), P < 0.05]. Exercise performance times did not differ between recovery conditions (P = 0.28). No difference was found between conditions for recovery kinetics (slope and half-time to recovery). Subsequent performance during multiple bouts of intense exercise to exhaustion may not be influenced by blood acidosis or mode of recovery.

Effects of recovery type after a judo match on blood lactate and performance in specific and non-specific judo tasks

“…The results of the present study are also in line with those of the previous ones which reported that AR was better than PR for lactate removal from the blood (Greenwood et al 2008;Siegler et al 2006;McAinch et al 2004;Gupta et al 1996;Weltman and Regan 1983;Weltman et al 1979). The moment when the differences started (9-10 min after the match) is similar to that reported in studies using other tasks (Hudson et al 1999;Gupta et al 1996) and with a previous study with a judo match simulation (Franchini et al 2003).…”

“…For recovery periods of 10-20 min some studies have indicated that active recovery (AR) is better than passive recovery (PR) for blood lactate removal (Greenwood et al 2008;Siegler et al 2006;McAinch et al 2004;Gupta et al 1996;Weltman and Regan 1983;Weltman et al 1979). However, the effect of AR on subsequent performance is controversial when the interval between the first and the second bout is 10-20 min (Greenwood et al 2008; Monedero and Donne 2000;Watts et al 2000;Thiriet et al 1993;Bond et al 1991;Weltman and Regan 1983;Weltman et al 1977Weltman et al , 1979.…”

Blood lactate removal after a rowing all-out test depends on the active protocol proposed

“…However, it should also be considered that scientific evidence of a performance decrease after active recovery has been reported [36][37][38][39]. As such, it is necessary to continue studying this issue, particularly in rowers because the literature regarding this discipline is still incipient [7,18].…”

Effects of Gas Exchange on Acid‐Base Balance

“…It has been hypothesized that an active recovery process, that is maintaining some level of activity of the exercised muscle groups during the immediate postexercise recovery period, is beneficial for the restoration of blood acid-base state (55,270,271) and muscle function (270). These studies demonstrated that low-intensity, prolonged activity during rest periods between bouts of high-intensity exercise increase the rate of clearance of plasma H + and lactate − .…”
