Effects of acute taurine consumption on single bout of muscular endurance resistance exercise performance and recovery in resistance trained young male adults

Abstract

Study aim: This study investigated the effect of taurine supplementation on exercise performance and recovery from resistance exercise. The study was conducted with a cross-over design in a double-blind manner. Material and methods: Ten resistance trained males (age 21.4 ± 2.01 years; BMI: 23.6 ± 2.5 kg/m²) ingested either a taurine (0.1g/kg) supplement or placebo (18 mg aspartame) prior to resistance exercise. Vertical jump, flexibility, balance, systolic blood pressure, diastolic blood pressure, heart rate (HR), maximal voluntary muscle contraction, speed, lactate, glucose and perceived soreness and strain were assessed. The subjects performed two exercise trials with 1 week wash out interval. Blood samples were collected at baseline and before each exercise (chest press, abdominal crunch and leg extension) to analyse plasma levels of lactate and glucose. Results: Paired-T test results showed statistically significant increment (p < 0.05) in total volume (kg × #repetitions), chest press volume and leg extension volume. Repeated measure ANOVA results demonstrated statistically significant differences (p < 0.05) in lactate and flexibility in trial and time, and in maximal voluntary isometric muscle contraction (MVIC) test in time, trial and trial × time in favour taurine group. No statistically significant differences were found in cardiovascular parameters, glucose, and balance parameters (p > 0.05). Conclusion: In conclusion, 0.1 g/kg of taurine consumption before resistance exercise could positively affect exercise performance by increasing exercise volume and reducing lactate levels.

What Nutraceuticals Can Do for Duchenne Muscular Dystrophy: Lessons Learned from Amino Acid Supplementation in Mouse Models

“…In healthy subjects, benefits of Tau supplementation on aerobic and anaerobic performance, muscle damage, metabolic stress, and recovery have been reviewed recently, concluding that evidence so far shows varied and mostly limited effects [93]. However, a placebo-controlled evaluation of single oral administration of 0.1 g/kg Tau before resistance training did observe a significant positive effect on exercise performance [94], and a meta-analysis of ten published studies concluded that Tau supplements of 1 to 6 g/day for 2 weeks did improve endurance performance [95]. Overall, Tau supplementation was well tolerated, as no severe adverse events have been reported.…”

Effect of rest duration between sets on fatigue and recovery after short intense plyometric exercise

“…Muscle fatigue is the inability of a muscle or group of muscles to produce the required static force or mechanical power within a set time, or the inability to perform the total amount of work under certain conditions 17 . The development of muscle fatigue is determined among others by the availability of energy substrates and the accumulation of products of their metabolism 18 – 20 . Muscle work requires the intensification of various processes in muscle cells to meet the high demand for ATP.…”
