For a rugby expert like John Pryor, strength and conditioning principles can be accurately applied to just about any subject and can lead to a deeper understanding of the interrelationship between two seemingly disparate concepts. When it comes to renewable energy technologies and practices, John Pryor, rugby strength and conditioning coordinator for the Japan Rugby Football Union, is able to immediately recognize similarities between the two, particularly as it relates to training principles relating to overtraining as well as the need for variance among training stimuli. Of course, the comparison is not always entirely precise, but the general concepts tend to be so similar that athletes are able to better understand the rationale behind best practices when it comes training principles.
With regard to the need to target different goals through a training program, most athletes understand that training must be varied in order to yield the kind of all-encompassing fitness gains needed to excel in any kind of athletic competition. When an athlete does not incorporate differentiated training stimuli with the goal of yielding a broad range of fitness adaptation, the outcome can be quite similar to some of the current issues relating to the need to shift to alternative sources of energy. Focusing on a singular form of training is akin to utilizing only non-renewable energy resources, with the result being quite devastating in both situations.
