Understanding the demands of Judo part 1…..

Before we can understand the physiological demands of judo we must first understand how researchers develop an understanding of sport.

Understanding the Demands of sport

In order for coaches to be able to train athletes to compete and win in their chosen sport their must be an understanding of the sport in question. The coach must understand the demands of the sport from four perspectives:

  • Physiological demands
  • Technical demands
  • Tactical demands
  • Mental demands

The coaches understanding of technical and tactical demands are developed through experience as a coach and sometimes as an athlete. Further understanding of these demands can be developed through performance analysis in the forms of biomechanics and notation. Various authors have developed coaching knowledge of the technical requirements of their sport including (Palao et al, 2009; Laird & McLeod, 2009, Bruce et al, 2009) others have focussed on the tactical requirements (Costa et al,  2011; da Costa et al,  2010; Remmert, 2003).

Understanding the mental demands of sport is complex. Firstly you have the pressure of the sporting environment and the mental demands this elicits such as anxiety, self-efficacy and concentration. You also have the mental challenges of training that include motivation, determination and ability to set goals. Lastly you have the cognitive ability to deal with complex tasks in a time constrained environment.

Understanding the physiological demands is no less complex and will be the focus of this section. There are four common methods of investigating the physiological demands of sport and each has it merits and pitfalls.

  • Time motion analysis
  • Physiological testing during competition
  • Physiological testing post competition
  • Testing athletes physiological attributes

Each of these is described in table 1.

Table 1: Methods of assessing the physiological demands of sport and their merits and pitfalls.


Modern research tends to combine these methods for a more holistic enquiry. Part two will consider the physiological demands of judo.
