This study examined 1) the plasma taurine response to acute oral taurine supplementation (T), and 2) the effects of 7 days of T on muscle amino acid content and substrate metabolism during 2 h of cycling at approximately 60% peak oxygen consumption (VO2peak). In the first part of the study, after an overnight fast, 7 volunteers (28+/-3 yr, 184+/-2 cm, 88.0+/-6.6 kg) ingested 1.66 g oral taurine doses with breakfast (8 AM) and lunch (12 noon), and blood samples were taken throughout the day.

Taurine Supplementation Increases Post-Exercise Lipid Oxidation at Moderate Intensity in Fasted Healthy Males

Six grams of TAU supplementation 90 min before a single bout of aerobic exercise in a fasted state was sufficient to increase the lipid oxidation post-exercise in healthy young men.

The effect of acute taurine ingestion on endurance performance and metabolism in well-trained cyclists.

The acute ingestion of 1.66 g of T before exercise did not enhance TT performance but did result in a small but significant increase in fat oxidation during submaximal cycling in endurance-trained cyclists.

The effect of acute taurine ingestion on 4-km time trial performance in trained cyclists

It is suggested that a pre-exercise dose of 1000 mg TAU offers no performance advantage during 4-km TT nor does it alter the blood buffering responses in trained cyclists.

and tolerance

Oral taurine improves critical power severe intensity exercise and estimated performance at a range of severe work intensities and time to exhaustion 5% > critical power (TTE) and the estimated time to complete (T lim) arange of fixed target intensities.

Oral taurine improves critical power and severe-intensity exercise tolerance

Acute supplementation of 50 mg kg−1 of taurine improved CP and estimated performance at a range of severe work intensities and estimated time to complete (Tlim) arange of fixed target intensities.

Effect of taurine supplementation on the alterations in amino Acid content in skeletal muscle with exercise in rat.

Taurine ingestion significantly decreased certain amino acids in skeletal muscles accompanied with enhanced exercise performance, and the taurine-induced reductions of these amino acid in skeletal muscle might be one of mechanisms which underpin the enhancement of exercise performance by taurines.

Taurine supplementation improves economy of movement in the cycle test independently of the detrimental effects of ethanol

Findings indicate that taurine improves EM and counteracts ethanol-induced increases in HR during submaximal exercise.

Acute taurine supplementation enhances thermoregulation and endurance cycling performance in the heat

A single dose of taurine 2 h prior to training or competition would provide an ergogenic and thermoregulatory effect and have implications for the short-term preparation strategies of individuals exercising in the heat.

Effects of taurine supplementation in elite swimmers performance

Aim: Taurine is considered a semi-essential amino acid characterized by having various physiological functions in the body that modulate mechanisms of action involved in the muscle contraction…

Effects of taurine administration on exercise-induced fatigue and recovery

It is found that post-exercise taurine administration enhanced the recovery of skeletal muscle glycogen, which is the major determinant for exercise performance.

Training and muscle ammonia and amino acid metabolism in humans during prolonged exercise.

Under these conditions, prolonged dynamic knee extensor exercise is associated with a large release of alpha-amino moieties both as NH3 and as Gln as well as a net protein catabolism; these responses are similar in Tr and Utr.

Effects of taurine administration in rat skeletal muscles on exercise

It is concluded that peroral administration of taurine maintains the t aurine concentration in skeletal muscle on exercise and up-regulates physical endurance.

Decreased taurine concentration in skeletal muscles after exercise for various durations.

Taurine concentration was decreased in all skeletal muscles after exercise, regardless of the duration, and this decrease was specific to fast-twitch dominant fibers.

Plasma and muscle amino acid and ammonia responses during prolonged exercise in humans.

Plasma and muscle amino acid (AA) and ammonia (NH3) responses were measured during prolonged submaximal exercise in humans and suggest that protein catabolism was occurring during exercise and the branched-chain AA were used for energy and NH3 production.

Elevation of creatine in resting and exercised muscle of normal subjects by creatine supplementation.

Competition with 5g of creatine monohydrate, four or six times a day for 2 or more days resulted in a significant increase in the total creatine content of the quadriceps femoris muscle measured in 17 subjects, and in some the increase was as much as 50%.

Changes in plasma and urinary taurine and amino acids in runners immediately and 24 h after a marathon

Summary. Changes in urinary and plasma taurine and amino acids have been evaluated in trained runners competing in the Rotterdam Marathon, 1998, both immediately after completing the event and 24 h…

Oral taurine supplementation prevents fructose-induced hypertension in rats

Taurine may ameliorate fructose-induced hypertension in rats by preventing an increase in intracellular free calcium concentration and the blood pressure-lowering effect of taurine appeared to be independent from its effect on glucose and lipid metabolism in this model.

Effect of exercise on amino acid concentrations in skeletal muscle and plasma.

There is a significant activation of branched-chain amino acid metabolism with prolonged exercise, and the current data indicate that this is more pronounced in endurance-trained subjects than in untrained controls.

Effect of taurine treatment on insulin secretion and action, and on serum lipid levels in overweight men with a genetic predisposition for type II diabetes mellitus

Findings in persons with an increased risk of T2DM are in contrast to those from animal studies, and do not support the assumption that dietary supplementation with taurine can be used to prevent the development of type 2 diabetes mellitus.

Effect of muscle glycogen on glucose, lactate and amino acid metabolism during exercise and recovery in human subjects

The results suggest that the observed differences in metabolism between the low‐ Glycogen and the normal‐glycogen leg are induced by the glycogen level per se, since the legs received the same arterial supply of hormones and substrates.
