Introduction “The human body is an adaptable living organism. It is nothing more than an interdependent matrix system that communicates with and amongst itself all day long through electronically charged molecules-you are an ever evolving and fluctuating organism that is self- regulating and supercompensating-you are nothing more than a bio-electrical field that is hell bent on one function--SURVIVAL!” Buddy Morris
Factors Affecting Jumps 1. Vertical jump performance is determined by a complex interaction among several factors, including the maximal force that the involved musculature can develop, how fast that force can be developed, and the neural coordination of the movement. 2. A portion of the power developed during a vertical jump is derived from the stretch-shortening cycle that enhances muscular force by evoking the stretch reflex, and utilizes elastic energy stored in stretched tissues.
Factors Affecting Jumps The vertical jump is a complex multi-joint movement that requires muscle coordination best improved by specific skill development. Traditional strength training, explosive types of weight training, plyometrics, and Olympic lifting can be effective for increasing vertical jump. The form of training that is most effective is determined by the relative strengths and weaknesses of the athlete.
Strength Characteristics Isometric force: time curve indicating maximal strength, maximal rate of force development, and force at 200 ms for untrained, heavy-resistance strength-trained, and explosive-strength-trained subjects (adapted from Häkkinen et al., 1985 a, b).
What is Strength? The ability to exert a force against a resistance. F=ma (Newton’s 2 nd Law of Motion) Dynamic strength is defined as the maximal ability (capacity) of a muscle to exert force or torque at a specified velocity (Knuttgen & Kraemer, 1987)
Force-Velocity Characteristics Force-velocity curve showing how power can be related to these qualities

Planning & Organising “If you fail to plan, you plan to fail” Programmes Loading patterns Periodisation cycles Priorities
Priorities “Be careful over emphasising qualities that are not specific to the primary components or objectives of the training cycle, because you will have too many qualities competing for the draw on the nervous system.” Charlie Francis Neuromuscular demands Metabolic demands
Priorities Demands of the event? What really matters How strong is strong enough? Strengths vs. Weaknesses Biggest gains – best use of time Time of year/periodisation cycle Level of athlete/training age
Aspects of Programming 1. Strength 2. Movement 3. Conditioning 4. Power / Speed
Planning a programme Strength Fundamentals e.g. Olympic lifts & variations Squats Dead lifts; RDL’s Supplementary exercises Upper body Lower body smaller muscle groups
Planning a programme Warm-ups ‘Core’ conditioning Drills Plyometrics Hurdle work Lifting technique Injury prevention / muscle balance Assisted running / jumping (Ritzdorf, 1998) Decreasing the external loads when performing jumps is a good stimulus to develop the velocity component of explosive strength.

Good Coaching/Good Training “Repetition is the mother of learning” Latin Proverb “Precise repetition is the mother of excellence” Quality is better than quantity, but a larger quantity of quality work is best Intent
Intent “Intension to move the bar quickly rather than the actual speed of the bar is the goal” (Young & Bilby, 1993) Better recruitment of motor units Synchronisation Muscles activated at higher frequency Transfer of force “You can’t push rope...” Focus
Monitoring Strength diagnostic tools - KMS, BMS, Tendo, Musclelab Record keeping/training diary Monitoring Load Metres Minutes Contacts To build Work Capacity
Monitoring: Jump Height Factors Components of vertical jump performance: Athlete's maximal leg strength Maximal rate at which force can be developed Ability of the athlete to increase power by employing the stretch-shortening cycle during the crouch before the jump Ability of the athlete to generate maximal mechanical power Ability of athlete to coordinate the movements involved in jumping
Monitoring: Jump Height Factors Monitoring Directs Training Monitoring on a regular basis could be important in helping the coach to determine which component is deficient so that training can be implemented to address the deficiency and to provide motivation to the athlete.
