Abstract
This study aimed to determine how guanidinoacetic acid (GAA) or its combined administration with betaine (B) or creatine (C) influences the cardiac function, morphometric parameters, and redox status of rats subjected to high-intensity interval training (HIIT). This research was conducted on male Wistar albino rats exposed to HIIT for 4 weeks. The animals were randomly divided into five groups: HIIT, HIIT + GAA, HIIT + GAA + C, HIIT + GAA + B, and HIIT + GAA + C + B. After completing the training protocol, GAA (300 mg/kg), C (280 mg/kg), and B (300 mg/kg) were applied daily per os for 4 weeks. GAA supplementation in combination with HIIT significantly decreased the level of both systemic and cardiac prooxidants ( O 2 - , H2O2, NO 2 - , and thiobarbituric acid reactive substances) compared with nontreated HIIT (p < 0.05). Also, GAA treatment led to an increase in glutathione and superoxide dismutase levels. None of the treatment regimens altered cardiac function. A larger degree of cardiomyocyte hypertrophy was observed in the HIIT + GAA group, which was reflected through an increase of the cross-sectional area of 27% (p < 0.05) and that of the left ventricle wall thickness of 27% (p < 0.05). Since we showed that GAA in combination with HIIT may ameliorate oxidative stress and does not alter cardiac function, the present study is a basis for future research exploring the mechanisms of cardioprotection induced by this supplement in an HIIT scenario.

Abstract
Sprague-Dawley rats (n = 32) underwent 8-weeks of creatine monohydrate (CM) supplementation (0, 2.5, 5, and 10 g/L). Total creatine (TCr) concentrations in female white fibre-dominant gastrocnemius (WGAS) and cardiac muscle (HRT) were significantly higher compared with males (p < 0.05). CM supplementation increased TCr concentrations in female WGAS (p < 0.05) and HRT (p < 0.01) and in male red fibre-dominant gastrocnemius muscle (RGAS) (p < 0.05). Future research should further investigate sex-differences in basal levels of TCr and the response to CM supplementation. Novelty: There is a sex- and tissue-dependant response to CM supplementation in rats.

Abstract
We evaluated whether twice-daily consumption of a multi-ingredient nutritional supplement (SUPP) would reduce systemic inflammatory markers following 6 weeks of supplementation alone (phase 1), and the subsequent addition of 12 weeks of exercise training (phase 2) in healthy older men, in comparison with a carbohydrate-based control (CON). Tumour necrosis factor-alpha (TNF-α) and interleukin-6 (IL-6) concentrations were progressively reduced (P-time < 0.05) in the SUPP group. No change in TNF-α or IL-6 concentrations was observed in the CON group.

Abstract
We evaluated the effects of exercise on circulating concentrations of guanidinoacetic acid (GAA) and creatine in 23 healthy volunteers subjected to running to exhaustion and free-weight bench-press to volitional failure. Blood was taken before and following each exercise session. Running induced a significant decrease in serum GAA by 20.1% (P < 0.001), while free-weight exercise reduced GAA by 11.7% (P < 0.001), suggesting the possible use of serum GAA as a novel biomarker of exhaustion.
