According to authors opinions it is possible that the addition of creatine and subsequent increase in total creatine and phosphocreatine storage might have directly or indirectly stimulated production of muscle IGF-I and muscle protein synthesis, leading to an increased muscle hypertrophy [ 2 ].

Using muscle biopsies of the vastus lateralis, a descending trend for groups and mean percentage fiber type was observed. Effect of 28 days of creatine ingestion on muscle metabolism and performance of a simulated cycling road race.

Hile et al [ 46 ] observed an increase in compartment pressure in the anterior compartment of the lower leg, which may also have been responsible for a reduced active ROM.

Furthermore, a questionnaire was used to determine creatine use amongst this age group and does not necessarily reflect the truth.

These effects have been attributed to improved overall cellular bioenergetics due to an expansion of the phosphocreatine pool [ 50 ]. Jakobi et al [ 23 ] found no effects of a short term creatine loading protocol upon isometric elbow flexion force, muscle activation, and recovery process.

Long term and epidemiological data should continue to be produced and collected to determine the safety of creatine in all healthy individuals under all conditions [ 78 ].

If distributed thoroughly and safely then performance enhancing drugs should be legal.performance enhancing drugs in sports, doping is arguably the most controversial and most talked-about issue in modern sports.

Creatine may serve as an agent to improve cognitive abilities, prevent disuse atrophy in injured athletes, and help with recovery from concussions.
