Sports Supplements – Ergogenic Aids

Summary

Introduction

These consist of vitamins, synthetic drugs and hormones, which are used by athletes to enhance their athletic performance.

Iron – This is responsible for carrying oxygen to blood cells and removing carbon dioxide. Anaemia is characterised by exhaustion and fatigue, so the correct amount is essential for athletic performance. Females, adolescent males, vegetarian and endurance athletes may be deficient in iron and need to take a supplement.

Calcium – Particularly in female athletes whose menstrual cycle has stopped. The low eostrogen levels means a loss of calcium from bone tissue and puts bones at risk of osteoporosis.

There are certain supplements that are safe, legal and help to improve athletic performance.

Creatine

Creatine is produced naturally by the body and helps to improve muscle performance during exercise to allow people to train at higher levels. It aids recovery between short bursts of energy, so benefits training and gives an edge in competition.

Creatine increases body weight and composition with muscle mass increased by 4kg in 8 weeks. Most beneficial for anaerobic performance, but may also boost lactate thresholds in aerobic activity.

Glutamine

Glutamine is a non-essential amino acid, primarily produced in the muscles and plays an important part in keeping them functioning normally.

Glutamine is used by white blood cells and contributes to normal immune system functioning. It nourishes cells that line the intestine and stomach and may protect against gastric lesions.

Once in the brain it is converted into glutamic acid and increases the concentration of GABA – both are essential for proper mental functioning. May be of benefit to those with muscle-wasting and immune related illnesses who may be incapable of producing their own glutamine (Crohns disease).
