The effects of Creatine in Sports Performance

The criteria for the selected article is that each study requires participation in a physical examination or exercise examination before CR ingestion and before CR ingestion, without including other supplements, steroids, health related drugs. All research papers were double blind in the placebo group to prevent bias and placebo effects. All studies have been done in the last 16 years, and the purpose of gender balance is to be fair, but resources are mainly for men.

Creatine monohydrate supplements are popular among athletes participating in muscular strength and muscular strength sports. The use of creatine is thought to be effective in improving the performance of activities, including repetition intervals of short-term type of sprint exercise. First, the increase in PCr storage should increase the contribution of PCr to resynthesis and decrease the need for glycolysis, which will result in less accumulation of lactic acid. When PCr decomposes and ADP is rephosphorylated, hydrogen ions are consumed during the reaction. Thus, an increase in PCr can delay the onset of acidosis and fatigue, thereby improving the performance of repetitive splints (Chilibeck & Cornish, 2006).

Muscle supplements have been used by athletes of recreational and athletic competitions as effective exercise supplements for over 10 years to improve exercise performance. Supplements have been shown to increase intramuscular creatine stock from 5% to 30% (16). A typical creatine supplement regimen is a loading dose of 20 g / d -1 during the supplement period followed by a 5-day loading dose of 3 to 5 g / d -1 (16). Studies have shown that ingestion of glucose (eg 35-95 g) by creatine or glucose + protein (eg 50 g each) increases the amount of creatine stored in muscle. These findings are reported to be related to changes in insulin circulation levels (10, 11). A recent review of Kreider in 2003 reported that 70% of the studies comparing strength training and more than 300 creatine supplements showed an increase in efficacy (25)
