“…Thus, after that equilibrium has been attained, two possibilities are given: (i) these capacitances differ in size or in resistance, so that the process of lactate removal is characterized by different time constants, in which case two exponentials are necessary to characterize the function describing lactate removal from the body, or (ii) these two capacitances have the same size and resistance, so that the process of lactate removal from the two body fluids is characterized by equal time constants, in which case a mono-exponential fully describes the entire phenomenon. The body of evidence in favour of the latter hypothesis is important though ancient (Åstrand 1960;di Prampero et al 1978a, b;Gisolfi et al 1966;Hermansen and Stensvold 1972;Margaria et al 1933Margaria et al , 1963b.…”

Powers higher than the maximal aerobic power can be attained relying on anaerobic lactic and alactic metabolisms as energy source. These metabolisms are analysed separately in this Chapter, where the power and capacity of both have been quantified. Anaerobic lactic metabolism has been treated first, although it is still a controversial issue on quantitative grounds, because several authors denied the possibility of performing a correct estimate of the metabolic energy corresponding to a mole of lactate accumulation in blood. Thus, its analysis is preceded by a preliminary discussion of the principles and assumption behind the concept of energetic meaning of blood lactate accumulation is based. Then, anaerobic alactic metabolism is discussed, for which a distinction between average and instantaneous powers is introduced: the former reflects the rate of ATP resynthesis from the Lohmann's reaction and the latter refers to the maximal rate of ATP hydrolysis and concerns the ATP already available at the contraction site. This analysis shows that the maximal power generated by anaerobic alactic metabolism is extremely high, up to some 20 times higher than the maximal aerobic power for the instantaneous methods. The price to pay for this is an extremely low capacity, so that exercise can be sustained at maximal power only for a very short time, of the order of a few seconds for average power, some milliseconds for instantaneous power. Such an organization of energetic metabolism, with a wide range of powers and capacities for the ensemble of the metabolic pathways, allows animals, humans included, to face the multiple needs that a prey-predator system imposes. In general terms, animals have evolved in such a way that power is highest when capacity is lowest, and vice versa.

“…In studies that were carried out with the aim of determining the effects of different types of recovery exercises after exhaustive effort on blood lactate removal [7,8,9,10], results show that active recovery carried out in low intensity is more effective when compared with exercise recovery carried out in moderate intensity or passively. In general, the procedures used during active recovery vary according to the intensity of the activity, the type of exercise and the time of activity [8,11,12].…”

“…Moreover, more blood carrying lactate could reach the visceral region, considered an important site of lactate removal [10], as the venous return is facilitated in such conditions. Gisolfi et al [9] claim that the increase in the rate of lactate removal in recovery exercises is probably due to the following factors: 1) faster distribution of lactate to the liver for conversion into oxidation or glycogen, 2) increased use of the lactate by the heart muscle, and 3) possible increased oxidation of lactate used as fuel for muscle work. Therefore, the completion of 30 minutes of exercises after maximal effort contributes to the reduction of the oxygen debt.…”

Introduction. Despite physiological changes caused by immersion in liquid medium, few studies have been conducted to determine the kinetics of blood lactate removal under these conditions. The aim of this study was to verify the effect of active recovery, using a specific water bike, on the blood lactate concentration after maximum intensity exercise. Material and method. Ten healthy cycling athletes performed an Anaerobic Threshold Test by Heart Rate (HR) on a bicycle ergometer and an Anaerobic Threshold Test by Subjective Effort Perception on an aquatic bicycle ergometer. Three maximal test was performed immediately before each recovery type, in three different days: Passive Recovery on Land -PRL (horizontal position for 60 minutes), Passive Recovery in the Water -PRW (horizontal position, with the help of floats, in swimming pool for 60 minutes) and Active Recovery in the Water -ARW (the volunteer performed exercises on a water bicycle to an intensity corresponding to 85% of the intensity of LA in water, for 30 minutes, and remained in the same position of the PRW for another 30 minutes). Blood samples were collected 5, 15, 30 and 60 minutes after the maximal test, for lactate analysis. Results. The [La] blood did not show the difference between the three types of recovery at 5 th min. From 15 th min on, the difference between the ARW and the other two types of passive recovery was significant, and the ARW showed lower values. There was no significant difference between the PRW and PRL. Conclusion. Mere immersion in water is not enough to maximize the removal of blood lactate. This study demonstrates that active recovery held in water is effective for the removal of blood lactate in cyclists.

“…It is believed that the best recovery intensity would be at AT power output or even passive, since there is no lactate formation during light-intensity exercise. Two previous studies showed that the best lactate removal occurs for recovery intensities of 52% [41] and 63% of VO 2max [42]. When comparing active and passive recoveries, Abderrahmane et al [43] demonstrated that interval training in moderately trained individuals with active recovery increased VO 2max and maximal aerobic velocity.…”
