“…In accordance with the literature, the supramaximal exercise performed with normal frequency breathing (i. e., 1 breath every 4 strokes) induced a significant increase in heart rate and blood lactate in all subjects [9,14]. In parallel, it is interesting to note that the 50-m performed at maximal speed also induced, with normal frequency breathing, a significant decrease in arterial oxygen saturation in the whole population.…”

The aim was to assess the cardiac, arterial oxygen saturation, lactate, hormonal and Borg rating of perceived exertion (RPE) responses to acute apnea in relation to apnea capacity in 18 middle-aged triathletes. Subjects were monitored while swimming two 50-m freestyle exercise trials with fins at maximal speed: with normal frequency breathing (NB) and with complete apnea (Ap); the latter was used to assess apnea capacity. The subjects with significant alteration in swimming performance inducing a time increase greater than 2.5% during Ap vs. NB were put in the group: bad apnea capacity (Bad Ap); the others, who showed no significant alteration in performance, were put in the group: Good Ap. Under apnea, both groups showed a decrease in arterial oxygen saturation (p<0.05). In Ap conditions, only Bad Ap had a significant lower maximal heart rate vs. NB (p<0.05), with lower blood lactate (p<0.05) and arm stroke frequency (p<0.01). No change in saliva hormonal concentrations was found during the experiment for both groups, whereas RPE responses were increased in the Good Ap group under Ap vs. NB conditions. In conclusion, a good apnea capacity seems to be associated with lower cardiovascular and metabolic apnea alterations in middle-aged recreationally-trained triathletes.

“…These results are in line with previous studies that suggested that blood lactate recovery is faster in trained than untrained individuals during active recovery (Gmada et al, 2005), and that lactate recovery at a relative exercise intensity, expressed as a percentage of V O 2max , improves with increased aerobic power (Evans & Cureton, 1983). Further support for the role of V O 2max in lactate recovery comes from trained individuals who, compared with untrained participants, are able to remove lactate at higher exercise intensities (Davies et al, 1970;Dodd et al, 1984;Hermansen & Stensvold, 1972;Weltman et al, 1979).…”

The aims of the study were to investigate blood lactate recovery and respiratory variables during diagonal skiing of variable intensity in skiers at different performance levels. Twelve male cross-country skiers classified as elite (n06; V O 2max 07393 ml × kg (1 × min (1 ) or moderately trained (n06; V O 2max 06195 ml × kg (1 × min (1 ) performed a 48-min variable intensity protocol on a treadmill using the diagonal stride technique on roller skis, alternating between 3 min at 90% and 6 min at 70% of V O 2max . None of the moderately trained skiers were able to complete the variable intensity protocol and there was a difference in time to exhaustion between the two groups (elite: 45.097.3 min; moderately trained: 31.4910.4 min) (P B0.05). The elite skiers had lower blood lactate concentrations and higher blood base excess concentrations at all 70% workloads than the moderately trained skiers (all P B0.05). In contrast, V E /V O 2 and V E /V CO 2 at the 70% V O 2max workloads decreased independently of group (P B0.05). Partial correlations showed that V O 2max was related to blood lactate at the first and second intervals at 70% of V O 2max (r0(0.81 and r0(0.82; both P B0.01) but not to V E /V O 2 , V E /V CO 2 or the respiratory exchange ratio. Our results demonstrate that during diagonal skiing of variable intensity, (1) elite skiers have superior blood lactate recovery compared with moderately trained skiers, who did not show any lactate recovery at 70% of V O 2max , suggesting it is an important characteristic for performance; and (2) the decreases in respiratory exchange ratio, V E /V O 2 , and V E /V CO 2 do not differ between elite and moderately trained skiers.

“…Further, the Δ of whole blood LA showed no difference between both groups. This was also observed by Gmada et al who observed that whole blood LA peak values measured after different test modes did not differ between an aerobically trained and a untrained group (Gmada et al, 2005).…”

Introduction: To determine endurance capacity and to give specific training recommendations, blood lactate (LA) concentrations are frequently used in performance diagnostics. In blood, LA is stored in red blood cells (RBC) and in plasma. Higher LA uptake by RBC might lead to delayed muscle fatigue since RBC serve as a dilution space for LA and more LA can be taken up by plasma which is released from the working muscle. Therefore, the aim of this study was to investigate the distribution of lactate in plasma and RBC in aerobically well-trained athletes (AA) in comparison to an untrained control group (CG). Materials and Methods: 13 AA and 13 CG participated in this study and conducted a high intensive treadmill test consisting of 2x4 minutes of running at 95% of the maximal running velocity with an active break of 4 minutes. Venous blood was drawn before and after the test. LA was measured in whole blood, plasma and RBC. Further, the ratio (LARatio) was calculated using the following formula: LA of RBC / LA of plasma. Results: AA exhibit significantly higher values in VO2peak and maximum running velocity. After the running test, LA in whole blood, RBC and plasma is increased significantly in both groups. No interaction effect (group X time point) was observed in any parameter. Values of LARatio did not show any significant differences. Conclusion: This study showed that the LA distribution in RBC and plasma after a high intensity running test is very similar in well trained endurance athletes and in untrained control subjects. Hence, LA uptake by RBC cannot or only in part be seen as a
