Hydration status of rural forestery workers in South Africa:
The harsh work environment of the forestry worker predisposes to them hypohydration - a loss of body mass of as little as 2% results in a loss of coordination and concentration - as forestry work is the most dangerous occupation in the world hypohydration could result in fatalaties. It is therefore important to investigate the degree to which hypohydration is actually occurring in the industry and to consider appropriate solutions to prevent this.

Nutritional intake of rural forestry workers in South Africa:
Forestry work is classified as hard physical endurance exercise. Appropriate nutrition is essential for sustained exercise and therefore for the forestry workers to be able to perform their work efficiently. Little is known about the nutritional intake of forestry workers. As the forestry industy is considering supplementing their wages with rations it is important to investigate their actual intake to determine which supplementation would be the most effective.

Nutritional supplement use of adolescent rugby players:
Elite school rugby players strive to excel in their sport and are very susceptible to the marketing of a wide range of supplementation all claiming to enhance performance and offer a competitive edge. Some of these supplements contain illegal substances and others may be harmful to the player. Many of these have not been tested for safety in the adolescent. Before the athletes can be educated about the appropriate use of supplementation a knowledge of popular supplements is essential.
