Introduction
The saying ‘sport and exercise are good for your health’ appears at first to be an irrefutable fact. However in this assignment I am going to look the information and facts that agree with this statement, and then compare and contrast with the information that disagrees.

It has also been proven to increase neurogenesis, the creation of new neurons in the hippocampus in the brain. Studies have shown that humans begin to lose nerve tissue at approximately 30 years of age. The effect exercise has on the brain increases neural connections, creating a denser network so we are able to process and store information. It has also been shown to initiate brain-derived neurotrophic factor or BDNF that acts as a protective response to stress and improve synaptic plasticity which improves the efficiency of signal transmission between neurons. This transfer is generally considered the basis for learning and memory (McGovern, 2005).

The saying “too much of a good thing” (Shakespeare, 1623) comes in to play when planning a programme of exercise. An
