“…The effects of higher lactate concentration in limiting exercise performance during an intense intermittent exercise shown by Ahmaidi et al (1) are largely confirmed by other literature studies (4,17,19,5,25). We supposed in the present study that the lower blood lactate concentration associated with the higher HR and higher oxygen uptake values in SR could be the factors in favor of the higher time limit exercise duration obtained for SR compared with AR and PR ( Figure 5).…”

This study aimed to determine the effect of 3 different recovery modes (passive [PR], active [AR], and dynamic stretching [SR]) on exercise time to exhaustion (Tlim) and cardiorespiratory and blood lactate responses during supramaximal exercise. Exercise sessions consisted of 2 series of 4 repeated, intermittent supramaximal cycling exercise interspersed in random order with PR, AR, or SR before the supramaximal continuous cycling time limit (Tlim) exercise test performed at 120% of maximal aerobic power. Ten healthy volunteer soccer athletes aged 25.7 ± 2.4 years participated in this study. During each exercise session, heart rate (HR), oxygen consumption V(O2)), blood lactate concentration, and Tlim exercise performance were recorded. Higher values were obtained in HR (p < 0.01) and in V(O)2 (p < 0.001) with SR and AR compared with PR. Moreover, lower blood lactate concentration (p < 0.01) was observed with SR and AR compared with PR. A greater Tlim exercise duration was obtained for SR compared with AR (p < 0.05) and PR (p < 0.01). Dynamic stretching appeared as the best recovery mode to enhance performance and cardiorespiratory and lactate responses during intermittent supramaximal cycling exercise.

“…Interestingly, capillary density has been shown in animals to decrease during maturation, i.e., as the fiber cross-sectional area increases with respect to growth (58,62,63). A higher functional capillarization would also explain the faster lactate clearance previously reported after exercise (4,6,12,22).…”

We quantified energy production in 7 prepubescent boys (11.7 ± 0.6 yr) and 10 men (35.6 ± 7.8 yr) using (31)P-magnetic resonance spectroscopy to investigate whether development affects muscle energetics, given that resistance to fatigue has been reported to be larger before puberty. Each subject performed a finger flexions exercise at 0.7 Hz against a weight adjusted to 15% of their maximal voluntary strength for 3 min, followed by a 15-min recovery period. The total energy cost was similar in both groups throughout the exercise bout, whereas the interplay of the different metabolic pathways was different. At the onset of exercise, children exhibited a higher oxidative contribution (50 ± 15% in boys and 25 ± 8% in men, P < 0.05) to ATP production, whereas the phosphocreatine breakdown contribution was reduced (40 ± 10% in boys and 53 ± 12% in men, P < 0.05), likely as a compensatory mechanism. The anaerobic glycolysis activity was unaffected by maturation. The recovery phase also disclosed differences regarding the rates of proton efflux (6.2 ± 2.5 vs. 3.8 ± 1.9 mM · pH unit(-1) · min(-1), in boys and men, respectively, P < 0.05), and phosphocreatine recovery, which was significantly faster in boys than in men (rate constant of phosphocreatine recovery: 1.3 ± 0.5 vs. 0.7 ± 0.4 min(-1); V(max): 37.5 ± 14.5 vs. 21.1 ± 12.2 mM/min, in boys and men, respectively, P < 0.05). Our results obtained in vivo clearly showed that maturation affects muscle energetics. Children relied more on oxidative metabolism and less on creatine kinase reaction to meet energy demand during exercise. This phenomenon can be explained by a greater oxidative capacity, probably linked to a higher relative content in slow-twitch fibers before puberty.

Faster oxygen uptake kinetics during recovery is related to better repeated sprinting ability

et al. 2010

This study was designed to test the hypothesis that subjects having faster oxygen uptake (VO(2)) kinetics during off-transients to exercises of severe intensity would obtain the smallest decrement score during a repeated sprint test. Twelve male soccer players completed a graded test, two severe-intensity exercises, followed by 6 min of passive recovery, and a repeated sprint test, consisting of seven 30-m sprints alternating with 20 s of active recovery. The relative decrease in score during the repeated sprint test was positively correlated with time constants of the primary phase for the VO(2) off-kinetics (r = 0.85; p < 0.001) and negatively correlated with the VO(2) peak (r = -0.83; p < 0.001). These results strengthen the link found between VO(2) kinetics and the ability to maintain sprint performance during repeated sprints.
