About us

Performance sport strives to increase participants' fitness capabilities year on year in an attempt to create more competitive/winning athletes. This is exemplified by the recent surge in success in UK sport, particularly around Olympic sports.

One of the fundamental reasons for this success has been the implementation of scientifically rigorous training programmes to maximize the physical ability of many performers.

However, the downside of this push for ever greater improvement has been an increase in the likelihood of athlete injury/illness as the limits to what sports performers are capable of achieving are approached.

The aim of this research group is to investigate the efficacy of training modalities to deliver the physical changes athletes require, while limiting the potential negative impact on injury and illness likelihood.
