Svi efekti na ubrzanje srcanog rada su obicno indirektna posledica uzimanja kreatina, vise energije, osecaj da se vise moze, treninzi postaju intenzivniji...cesto ako se tome pridruzi i nedovoljna nadoknada tecnosti i kalijuma...moze doci i do palpitacija, hm, povremenih "preskoka"...dakle, akcenat na kalijum, jer kreatin povlaci sa sobom i kalijum u celije...
Mada kao i uvek ima onih kod kojih se tahikardija( ubrzan srcani rad) i palpitacije mogu javiti kao znak preosetljivosti na ovaj suplement...
Inace kod pacijenata sa kongestivnom srcanom insuficijencijom, pokazano je da kreatin ima pozitivan ucinak na srcani rad...smanjuje nivo triglicerida...
"Heart disease
A preliminary clinical study suggests that creatine supplements may help lower levels of triglycerides (fats in the blood) in men and women with high concentrations of triglycerides.
In a few clinical studies of people with heart failure, those who took creatine, in addition to standard medical care, were able to increase the amount of exercise they could do before becoming fatigued, compared to those who took placebo. Getting tired easily is one of the major symptoms of heart failure. One clinical study of 20 people with heart failure found that short-term creatine supplementation in addition to standard medication lead to an increase in body weight and an improvement of muscle strength.
Creatine has also been reported to help lower levels of homocysteine. Homocysteine is associated with heart disease, including heart attack and stroke.
Chronic Obstructive Pulmonary Disease (COPD)
In one double-blind study, people with COPD who took creatine increased muscle mass, muscle strength and endurance, and improved their health status compared with those who took placebo. They did not increase their exercise capacity. More studies are needed to see whether creatine has any benefit for people with COPD.
Muscular dystrophy
People who have muscular dystrophy may have less creatine in their muscle cells, which may contribute to muscle weakness. One study found that taking creatine led to a small improvement in muscle strength. However, other studies have found no effect.
Parkinson's disease
People with Parkinson's disease have decreased muscular fitness including decreased muscle mass, muscle strength, and increased fatigue. A small clinical study found that giving creatine to people with Parkinson's disease improved their exercise ability and endurance. In another clinical study, creatine supplements boosted participants’ moods and they didn’t need to increase their medicine dose as much as those who didn’t take creatine. More research is needed in this area.
