Lactate Levels

High-intensity intermittent bicycle exercise was used to deplete muscle glycogen levels by 70% and elevate blood lactate levels to greater than 13.0 mmol/l. Thereafter subjects either cycled with one leg for 45 min followed by 45 min of passive recovery (partially active recovery) or rested for 90 min (passive recovery). During the first 45 min of partially active recovery 1) blood lactate (P less than 0.05) and pH levels (P less than 0.05) returned more rapidly to preexercise values than during passive recovery, 2) the rate of net glycogen resynthesis (0.28 mumol . g-1 . min-1) was the same in both legs, and 3) muscle lactate levels were significantly lower (P less than 0.05) in the passive than in the active leg. Thereafter the rate of net muscle glycogen resynthesis was unchanged (0.26 mumol . g-1 . min-1) and lactate removal could theoretically account for only 18% of the glycogen resynthesized. Overall, the rate of muscle glycogen resynthesis and muscle lactate removal was not different from that measured during passive recovery. After high-intensity exercise 1) glycogen repletion is not impeded by light exercise, and 2) blood glucose is an important substrate for glycogen resynthesis.

The purpose of this study was to investigate the effect of two recovery strategies between men's gymnastics events on blood lactate removal (BL) and performance as rated by expert "blind" judges. Twelve male gymnasts (21.8 ± 2.4 years) participated. The sessions were composed of routine performances in the six Olympic events, which were separated by 10 min of recovery. All gymnasts performed two recovery protocols between events on separate days: Rest protocol, 10 min rest in a sitting position; combined protocol, 5 min rest and 5 min self-selected active recovery. Three blood samples were taken at 2, 5, and 10 min following each event. Gymnasts produced moderate values of BL following each of the six events (2.2 to 11.6 mmolúL−1). There was moderate variability in BL values between events that could not be accounted for by the athlete's event performance. Gymnasts showed higher BL concentration (p > .05) and significantly (p < .05) higher scoring performances (as rated by a panel of certified judges) when they used a combined recovery between gymnastics events rather than a passive recovery (ΔBL = 40.51% vs. 28.76% of maximal BL, p < .05, and total score = 47.28 ± 6.82 vs. 38.39 ± 7.55, p < .05, respectively).

Purpose:To examine the effects of active and passive recovery of various durations after a 100-m swimming test performed at maximal effort.Methods:Eleven competitive swimmers (5 males, 6 females, age: 17.3 ± 0.6 y) completed two 100-m tests with a 15-min interval at a maximum swimming effort under three experimental conditions. The recovery between tests was 15 min passive (PAS), 5 min active, and 10 min passive (5ACT) or 10 min active and 5 min passive (10ACT). Self-selected active recovery started immediately after the first test, corresponding to 60 ± 5% of the 100-m time. Blood samples were taken at rest, 5, 10, and 15 min after the first as well as 5 min after the second 100-m test for blood lactate determination. Heart rate was also recorded during the corresponding periods.Results:Performance time of the first 100 m was not different between conditions (P > .05). The second 100-m test after the 5ACT (64.49 ± 3.85 s) condition was faster than 10ACT (65.49 ± 4.63 s) and PAS (65.89 ± 4.55 s) conditions (P < .05). Blood lactate during the 15-min recovery period between the 100-m efforts was lower in both active recovery conditions compared with passive recovery (P < .05). Heart rate was higher during the 5ACT and 10ACT conditions compared with PAS during the 15-min recovery period (P < .05).Conclusion:Five minutes of active recovery during a 15-min interval period is adequate to facilitate blood lactate removal and enhance performance in swimmers. Passive recovery and/or 10 min of active recovery is not recommended.

Effect of Different Types of Recovery on Blood Lactate Removal After Maximum ExerciseIntroduction. 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 5th min. From 15th 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.

We have investigated the metabolic fate of blood lactate in resting rainbow trout and in fish recovering from a bout of exhaustive exercise. At rest and during recovery from exercise, the majority of blood lactate was oxidized, the proportion increasing with increasing oxygen consumption. It is estimated that, during recovery from exhaustive exercise, lactate released from the muscle has the potential to fuel a significant portion of oxidative metabolism. The bulk of the remaining blood lactate reappeared in the muscle lactate pool, probably via direct uptake by the muscle. There was a significant incorporation of blood lactate into the muscle glycogen pool, providing strong evidence for in situ glycogenesis as the mode for muscle glycogen replenishment. To investigate the role of the liver in blood lactate clearance, trout were functionally hepatectomized by ligation of the hepatic portal circulation. The exercise performance of hepatectomized fish was equal to that of sham- operated fish and controls, indicating that muscle relies primarily on endogenous fuel stores. Furthermore, blood lactate levels immediately after exercise were greater and muscle metabolic recovery was faster in hepatectomized fish than in sham-operated fish and controls. These observations suggest that glycogen resynthesis in trout muscle may be retarded because of a non- recoverable loss of substrate (i.e. lactate) from the muscle, because the lactate released is utilized by the liver. These results are discussed in view of what is known about these processes in other ectothermic vertebrates.

Blood Lactate Levels

The purpose of the study was to compare the effect of creatine and thiamine supplementation on heart rate recovery (HRR) and blood lactate levels. Twelve male students comprised the two experimental (creatine and thiamine) groups of the study. The creatine group was supplemented with 0,3 g per weight, with 30 ml of water per dose of creatine four times a day, at regular intervals during the day, for 6 consecutive days. The thiamine group received 10 mg per weight just one time 30 minutes after a meal with 150 ml of water at the last supplementation days. After the supplementation period, subjects completed the incremental treadmill after a dynamic warm-up that consisted of walking at 6 km/h for 3 minutes. An initial treadmill speed started with 8,64 km/h for two minutes at 0% gradient followed by an increase of 1,44 km/h every 30 s until subjects reached their volitional exhaustion. After exercise cessation subjects continued with an active recovery of 10.08 km/h for approximately 5 minutes. Heart rate (HR) was regularly assessed from the first 5 min of passive recovery. Blood lactate levels were measured in the 9th min of passive recovery. There were no statistically significant differences in heart rate recovery and blood lactate levels after supplementation, respectively (P > 0.05). Based on these results, it appears that creatine supplementation did not provide a different effect with thiamine on the recovery of heart rate and blood lactate levels.

Lactate Levels

Muscle glycogen levels in the perfused rat hemicorpus preparation were reduced two-thirds by electrical stimulation plus exposure to epinephrine (10(-7) M) for 30 min. During the contraction period muscle lactate concentrations increased from a control level of 3.6 +/- 0.6 to a final value of 24.1 +/- 1.6 mumol/g muscle. To determine whether the lactate that had accumulated in muscle during contraction could be used to resynthesize glycogen, glycogen levels were determined after 1–3 h of recovery from the contraction period during which time the perfusion medium (flow-through system) contained low (1.3 mmol/l) or high (10.5 or 18 mmol/l) lactate concentrations but no glucose. With the low perfusate lactate concentration, muscle lactate levels declined to 7.2 +/- 0.8 mumol/g muscle by 3 h after the contraction period and muscle glycogen levels did not increase (1.28 +/- 0.07 at 3 h vs. 1.35 +/- 0.09 mg glucosyl U/g at end of exercise). Lactate disappearance from muscle was accounted for entirely by output into the venous effluent. With the high perfusate lactate concentrations, muscle lactate levels remained high (13.7 +/- 1.7 and 19.3 +/- 2.0 mumol/g) and glycogen levels increased by 1.11 and 0.86 mg glucosyl U/g, respectively, after 1 h of recovery from exercise. No more glycogen was synthesized when the recovery period was extended. Therefore, it appears that limited resynthesis of glycogen from lactate can occur after the contraction period but only when arterial lactate concentrations are high; otherwise the lactate that builds up in muscle during contraction will diffuse into the bloodstream.

Lactate Levels

Arterial blood lactate was elevated by supine leg exercise (20 min at approximately 65% maximal oxygen uptake) in five untrained male subjects, and the contribution to blood lactate removal from passive uptake vs. metabolic disposal was compared in resting and lightly exercising (15% maximal voluntary contraction static handgrip) forearm skeletal muscle. An integrated form of the Fick equation was used to predict venous lactate levels resulting solely from passive equilibration of lactate between incoming arterial blood and the forearm muscles. In the resting forearm, predicted and measured venous lactate levels were closely correlated during the exercise period (r = 0.995, P < 0.001), indicating that lactate removal could be accounted for in terms of passive uptake alone. In the lightly exercising forearm, measured venous lactate levels were higher than both the arterial and predicted venous levels, indicating net lactate production. It was concluded that most of the blood lactate generated by moderate-intensity supine leg exercise is taken up passively and not metabolized by resting skeletal muscle and that the rate of lactate disposal is unlikely to be enhanced in lightly exercising muscle.

Response And Recovery

The effects of varying recovery modes and the influence of preexercise sodium bicarbonate and carbohydrate ingestion on repeated high intensity performance, acid-base response, and recovery were analyzed in 12 well-trained males. They completed three repeated high intensity running bouts to exhaustion with intervening recovery periods of 25 min under the following conditions: sodium bicarbonate, active recovery (BIC); carbohydrate ingestion, active recovery (CHO); placebo ingestion, active recovery (ACTIVE); placebo ingestion, passive recovery (PASSIVE). Blood lactate (BLa), blood gases, heart rate, and time to exhaustion were collected. The three high intensity bouts had a duration of138±9, 124±6, and121±6 s demonstrating a decrease from bout 1 to bout 3. Supplementation strategy had no effect on performance in the first bout, even with differences in pH and bicarbonate (HCO3-). Repeated sprint performance was not affected by supplementation strategy when compared to ACTIVE, while PASSIVE resulted in a more pronounced decrease in performance compared with all other interventions. BIC led to greater BLa, pH, and HCO3-values compared with all other interventions, while for PASSIVE the opposite was found. BLa recovery was lowest in PASSIVE; recovery in pH, and HCO3-was lower in PASSIVE and higher in BIC.

Effect Of Age

Purpose:Blood lactate concentration, [BLa], after swimming events might be influenced by demographic features and characteristics of the swim race, whereas active recovery enhances blood lactate removal. Our aims were to (1) examine how sex, age, race distance, and swim stroke influenced [BLa] after competitive swimming events and (2) develop a practical model based on recovery swim distance to optimize blood lactate removal.Methods:We retrospectively analyzed postrace [BLa] from 100 swimmers who competed in the finals at the Canadian Swim Championships. [BLa] was also assessed repeatedly during the active recovery. Generalized estimating equations were used to evaluate the relationship between postrace [BLa] with independent variables.Results:Postrace [BLa] was highest following 100–200 m events and lowest after 50 and 1500 m races. A sex effect for postrace [BLa] was observed only for freestyle events. There was a negligible effect of age on postrace [BLa]. A model was developed to estimate an expected change in [BLa] during active recovery (male = 0; female = 1): [BLa] change after active recovery = –3.374 + (1.162 × sex) + (0.789 × postrace [BLa]) + (0.003 × active recovery distance).Conclusions:These findings indicate that swimmers competing at an elite standard display similar postrace [BLa] and that there is little effect of age on postrace [BLa] in competitive swimmers aged 14 to 29 y.
