HOW CAN I GET TO MY DESTINATION?
Systems Approach
Phases of Athlete’s Development
Performance’s Determining Factors in Horizontal Jumps
Performance’s Determining Factors in Horizontal Jumps
Take-off velocity
Take-off angle
Take-off height
Air resistance
Run-up Speed X LJ Performance
(r = 0,95)
Moura e Mendes, 1983
Maximal Speed Development: Most Usual Training Means
40 - 60m (standing & flying starts)
Resisted running
Assisted running
Approach Run:
Velocity - Accuracy - Position (HAY)
Optimal Speed at the Run-Way
Beginners: < 90%
Developing athletes: > 90%
Elite athletes: > 95%

Muscle Fibers Reconversion in Response to Heavy Weight Training and Detraining.
(Andersen, Schjerling & Saltin, 2000).
How to Integrate these “Conflicting” Information?
Heavy weight training: Limited to 6-9 weeks during 1st MAC;
Can be resumed for 2-3 weeks, 2 or 3 times throughout the year (minimum of 3 months between these short cycles);
Special training: Choose loads that allow the expression of MAXIMAL POWER.
Adaptation to Strength & Muscle Power Training (Sale, 1992)
Hypertrophy:
Sarcoplasmatic X Miofibrillar (Zatsiorsky, 1995)
Objectives of Strength Training for Horizontal Jumpers
Selective hypertrophy of Fibers type II;
Ú Recruitment
Ú Frequency of activation
Ú Synchronization
Maximal Power production in CKC exercises
Qualitative X Quantitative Approaches in Jumper’s Training
Quantitative
- Traditional
- Emphasis on amount of work performed
Qualitative
- Modern
- Emphasis on power produced and technique displayed at each repetition of a given task
Qualitative Approach:
Long X Short Cycles
Qualitative Approach: Long X Short Cycles
Training Control
Training Control is more difficult when we follow the QUALITATIVE approach;
Objective Control: CMJ Daily Test;
Subjective Control: RPE (Borg) and Rate of Well-Being;
“Fine-tuning”: MUST be done, everyday.

Plyometrics
Exercises that “activate the stretch-shortening cycle of skeletal muscles, inducing the elastic, reflex and mechanical potentiation”
Factors to be considered during plyometrics: amplitude and speed of eccentric phase, and coupling time between eccentric and concentric phases (Cavagna, 1977).
The most favorable situation in track and field combines small amplitude, high speed of the eccentric phase and a short coupling time.
Plyometrics: Depth Jumps
Free Fall
Shortest Contact Time
Highest Rebound Jump
Plyometrics: Optimal Eccentric Load
Optimal height for training is considered the one that allows the best jump after the free fall (BOSCO, 1985)
Depth Jump’s GRF: Elite X Beginners
Plyometrics X Heavy Weights (Sale, 1992)
Plyometrics: Inhibition X Facilitation
Complex Method
Increasingly popular among jumpers.
Plyometrics and Weight Training co-exist in the training process of jumpers;
Goal: To increase the possibility of training effects transference in direction of the real competitive situation, playing with the central nervous system by varying type and intensity of stimulus.
Suspension Training: facilitation to create a new motor program
RITZDORF (1998): Decreasing external loads when performing jumps is a good stimulus to develop the explosive strength’s velocity component;
New motor programs – predominantly fast – can be developed with the systematic use of  facilitation methods;
Short time programs can be reproduced when the facilitation is removed;
Central nervous learning effect: athletes of all age groups can use it – it is a special method, but not restricted to elite athletes.
Suspension Training
Effects of Suspension Training (Imachi et al, 1997)
Conclusions
New qualitative approaches must have priority over the traditional quantitative one: monitoring training daily, in this case, is of crucial importance;
Training effects are absolutely specific;
Special training – in a well organized way – should be done throughout the year by elite jumpers;
General training is important as long as it helps to promote recovery, to prevent injuries and to create the basis for the special capacities development;
In order to improve speed and special strength, methods of FACILITATION also must be used.
