About this deal
While the effects of ingesting these compounds on health are unknown, contamination with dihydrotriazine has been suggested to be of greatest concern since it is structurally related to carcinogenic compounds [ 197]. If the link between creatine supplementation and kidney health was valid, there would be an expected increase in kidney damage / renal dysfunction in low risk (i. e., immunosuppressant) for 5 years, had recently begun ingesting creatine supplementation (15 g/day for 7 days; followed by 2 g/day for 7 weeks).
For example, in a survey involving 219 athletes, 90 participants reported using creatine with 34 of them (38%) reporting perceived negative effects such as cramping (27%) [ 77]. Similarly, in National Collegiate Athletic Association (NCAA) Division 1 baseball and football players (N=52) using creatine, 25% reported incidences of muscle cramping and 13. Creatine supplementation has been shown to significantly augment cerebral PCr and P i [ 175], particularly in females.have not been replicated, and that intense resistance exercise itself can cause increases in these androgenic hormones. In summary, because creatine has a completely different chemical structure, it is not an anabolic steroid. The physiological rationale supporting the potential ergogenic benefits of creatine supplementation in children and adolescents was first postulated by Unnithan and colleagues in 2001 [ 80]; which established a strong basis for future applications of creatine for younger athletes.
Acute creatine supplementation (7 days) had no effect on fat mass in young and older adults; however, fat-free mass was increased [ 86, 87]. reported no significant effects of creatine loading on neuromuscular properties of fatigue in young adult females. From a clinical perspective, creatine supplementation has been found to potentially offer health benefits with minimal adverse effects in younger populations.Maternal creatine supplementation during pregnancy in pre-clinical animal studies have demonstrated a protective effect against fetal death and organ damage associated with intrapartum hypoxia [ 164, 165].
Furthermore, 5 g/day of creatine supplementation during 12 weeks of resistance training in postmenopausal females resulted in a significant increase in muscle mass and upper- and lower-body strength, compared to placebo [ 181].
