Catalyst Volume 22 Issue 4

This issue of Catalyst includes the following articles:

Fighting Fit

This Catalyst article looks at how exercise affects our immunity and susceptibility to infection. Recent research indicates that a person's level of physical activity affects their immune function, influencing their risk of respiratory tract infections such as a cold.

Building a White Water Canoe Course

This Catalyst article explores the processes undertaken during the construction of a white water canoe course for the Olympic Games which requires a huge range of practical skills, but also great science skills too.

Pedal Power

This article explores how having a knowledge of physics can help cyclists to understand better the limits to their performance.

The Systems Physiology of Exercise

This Catalyst article looks at the effect exercise has on the body. Scientists hope to understand the mechanisms which limit 'exercise tolerance' which would contribute to enhanced performance for the sports person and to good health and to quality and length of life for everyone.

Life Below the Surface

This Catalyst article looks at scuba diving, and how having a knowledge of physics is vital in helping divers to get out of dangerous situations.

Going Electric

This article explores electric transport which will be used to transport thousands of people during the Olympic Games, and thus needs to be energy-efficient and reliable.

Olympic Alloys

This Catalyst article looks at metals and alloys which play an important role in construction at the Olympic site, both in sports equipment and in medals.

Catalyst is a science magazine for students aged 14-19 years. Annual subscriptions to print copies of the magazine can be purchased from Mindsets.

Fighting Fit *suitable for home teaching*

This Catalyst article looks at how exercise affects our immunity and susceptibility to infection. Recent research indicates that a person's level of physical activity affects their immune function, influencing their risk of respiratory tract infections such as a cold. Whereas moderate levels of regular exercise...

Building a White Water Canoe Course

This Catalyst article explores the processes undertaken during the construction of a white water canoe course for the Olympic Games which requires a huge range of practical skills, but also great science skills too. The scientist must calculate how much noise from both the course's construction and its use during...

Pedal Power

This Catalyst article explores how cyclists can use physics to explain certain limitations to their performance. Variables which may affect a cyclist's speed such as force, energy and power are considered along with formulas for calculating the correct amount of each in order to optimise performance.

The Systems Physiology of Exercise *suitable for home teaching*

This Catalyst article looks at the effect exercise has on the body. Poor fitness contributes to poor life expectancy, and inability to exercise reduces quality of life in the ill or aged. Scientists hope to understand the mechanisms which limit 'exercise tolerance' which would contribute to enhanced performance for...
