Taurine and Exercise: Synergistic Effects on Adipose Tissue Metabolism and Inflammatory Process in Obesity.

Taurine has been investigated as a possible strategy for the treatment of obesity. The benefits of taurine supplementation and the importance of adipose tissue to the whole-body energy metabolism are undeniable; however, the impact of the association of taurine and exercise on adipose tissue dynamics remains unclear, especially in the context of obesity. The present investigation sought to explore the effects of taurine supplementation associated with physical exercise as an excellent strategy for treating and preventing obesity. We highlighted the main studies that support the effects of taurine associated with exercise on the modulation of energy and lipid metabolism and also its impacts on the adipose tissue metabolism and morphology in obese individuals and obese animal models, suggesting taurine as a promising strategy to combat obesity. However, more investigations are necessary to elucidate the safe and effective dose, the mechanisms, and the potential effects of taurine supplementation associated with exercise in the adipose tissue as a therapeutic strategy for preventing and treating obesity.

Taurine as a possible antiaging therapy: A controlled clinical trial on taurine antioxidant activity in women ages 55 to 70.

OBJECTIVE: Based on the antioxidant effects of taurine, which are capable of controlling oxidative stress in the aging process, the aim of this study was to investigate the effects of taurine supplementation on biomarkers of oxidative stress in women 55 to 70 y of age. METHODS: A double-blind study was conducted with 24 women (61.4 ± 4.2 y, body mass index 31.4 ± 5.1 kg/m²). The participants were randomly assigned to either a control group (GC, n = 11), supplemented with placebo (1.5 g of starch); or a taurine group (GTAU, n = 13), supplemented with taurine (1.5 g), for 16 wk. As primary outcomes, taurine and oxidative stress marker levels were determined in plasma samples. Anthropometry, functional capacity testing, and plasma mineral levels were evaluated as secondary outcomes. The evaluations were performed pre- and postintervention. Food consumption was assessed before, during, and after the intervention. The results were analyzed by two-way repeated analysis of variance measures mixed model, with the Sidak post hoc (P < 0.05). RESULTS: Taurine and superoxide dismutase (SOD, antioxidant enzyme) plasma levels were increased in the GTAU group. SOD levels also were higher than in the GC group after supplementation. Glutathione reductase levels decreased regardless of the intervention. Malondialdehyde levels increased only in the GC participants. CONCLUSION: Taurine supplementation prevented the decrease in the antioxidant enzyme SOD, suggesting taurine as a strategy to control oxidative stress during the aging process.

Casein and Whey Protein in the Breast Milk Ratio: Could It Promote Protein Metabolism Enhancement in Physically Active Adults?

Due to the utilization of milk proteins such as whey protein (WP) and casein as sports nutrition ergogenic aids, the present study investigated the effects of the association of WP and casein in a ratio of 80:20, a similar ratio of human breast milk, on blood branched-chain amino acid (BCAA) profiles, markers of protein metabolism and delayed onset muscle soreness (DOMS), after a single bout of resistance exercise. A double-blind, crossover and acute study was carried out with ten men (age 29 ± 8 years; BMI: 25.4 ± 2.9 kg/m2; 77 ± 12 kg; 1.74 ± 0.09 m); each one consumed the following supplements randomly, one per session: WP, CAS (casein), WP/CAS (80% WP/20% CAS), CAS/WP (80% CAS/20% WP) and PLA (placebo). They were also subjected to the following evaluations: the one repetition maximum (1RM) test; resistance training session; blood extraction during each session to determine the BCAA profile; two food records; 3-day evaluation of DOMS (24 h, 48 h and 72 h) and nitrogen balance in each treatment. The intervention resulted in similar nitrogen urinary, creatinine and urea plasma levels and showed a positive nitrogen balance in all the trials. Regarding the BCAAs, the peak occurred at 60 min post-ingestion and remained higher until 120 min for WP, WP/CAS and CAS/WP. The DOMS was significantly lower for WP, WP/CAS and CAS/WP compared to the CAS and PLA treatments. There were no advantages in the association of WP and CAS in the BCAAs profile when compared to WP itself, but it induced a lower DOMS compared to CAS and PLA (Clinical Trial registration number: clinicaltrials.gov, NCT04648384).
