The paper "Coaching Practice for an Explanation of Javelin Throw Movements"  is a delightful example of a literature review on sports and recreation.   Like any other throwing activity of the body, the javelin is a dynamic activity that makes use of the full body. It requires the involvement of all major muscles. Specifically, its mainstay of power and exertion is in the shoulder and arm muscles. However, it also requires a balanced involvement of the abdominals, the hips, and the lower limbs. There has been literature and coaching practice indicating that javelin is more than just a ‘ throw’ .

As such, whereas throws will only incorporate a predominantly activity of the arm, a javelin throw is a dynamic movement that is overarm with a whip-and-flail whole body technique (Rogers 2000). It is vital that a coach has an in-depth understanding of the principles and processes that underlie such combinations of movement. This paper is an explanation of javelin throw movements from the point of view of coaching science and practice using a right-hand throw. It will expound on the movement processes, the muscle involved as well as key performance indicators.

It will also evaluate a video of a javelin throw and use the indicators to point out the strengths and errors to which it will suggest possible workable interventions. Movement sequence and muscles The javelin throw is best done at the optimum moment. As a coach, the emphasis is made on the training the athlete for the technique of this release. This training is entrenched in ensuring that the performer understands and applies the relationship between the body and the javelin at the optimum release. This is in addition to the role of speed in approach and power in a release.

With reference to optimization, it is vital that all variables pertinent to a successful motion be either maximized or minimized. This variation of the interplay is tuned or balanced to a set of equation constraints relative to kinematic factors (Hughes & Franks 2004). The kinematic factors reveal a sequence of several phases: approach, transition, block and release, and follow-through. Given the complexity of a javelin throw and its aerodynamic differences with other throws, it is quite a task to differentiate these stages.

Davids (2006) points out that the performance analysis of movements of such complexity can only be predicted if explored over selected portions of the activity and not using isolated aspects.
