We read with great interest the paper by Dr Kenneth Quarrie, et al1. The review
provides an excellent summary of elite player physical demands, and the nature and measurement of the physical and non-physical loads that underpin these
demands. However, we believe that the lack of acknowledgement of sleep as an
important contributor to non-physical loads is an oversight. This is because sleep
has been shown in many studies to be important for optimal athletic performance (physical and cognitive components) and is recognised as an essential component of recovery.2 Indeed, it is considered by some to be one of a number of universal risk factors for sports injuries.3
