Strength, Speed, Resistance, Mobility & Coordination Training
Item 4: Force and Training
Manifestations of Force
The vast variety of sports practiced today demonstrates that muscles respond to diverse demands. Strength manifests differently depending on specific requirements.
Classifying Force
From a training perspective, strength is commonly classified as:
- Maximum Strength: The ability to achieve the maximum possible force (static or dynamic).
- Explosive Strength: The ability to achieve strength in the shortest possible time.
- Strength Endurance: The ability to maintain strength or repeat it many times.
Peak Force: Calculated from a single static repetition where there is muscle contraction but no movement of the load.
Classifying Force Manifestations
- Maximum Static Force: The highest force the neuromuscular system can develop through voluntary muscle contraction against a high resistance. Relates to isometric force.
- Maximum Dynamic Force: The force expressed to move the highest possible load with a single motion, without time limitations.
- Explosive Strength: The force expressed by a powerful contraction to move a load as fast as possible from a stationary position.
- Explosive-Elastic Force: The force resulting from energy stored in stretched muscle (eccentric phase) and used in propulsion (concentric phase).
- Explosive-Elastic-Reflex Force: Similar to explosive-elastic force, but performed faster, with a more limited eccentric phase.
Muscle Contractions
- Isometric Contractions: Muscle length doesn’t change.
- Anisometric Contractions: Muscle length changes.
- Isotonic (Isodynamic) Contractions: Constant force throughout the range of motion (uncommon in sport).
- Alodynamic Contractions: Force varies throughout the action.
- Isokinetic Contractions: Constant speed of movement.
- Heterokinetic Contractions: Variable speed of movement.
- Concentric Contractions: Muscle shortens while producing tension.
- Eccentric Contractions: Muscle lengthens while producing tension.
Common Combined Contractions
- Auxotonic: Combination of isotonic and isometric contractions.
- Plyometric: An eccentric contraction immediately followed by a concentric contraction.
Characteristics of Muscle Contraction
- Tonic Muscle Contraction: Long, strong contraction with a determined force evolution.
- Phasic Muscle Contraction: Cyclical movements requiring varying force magnitudes.
- Phasic-Tonic Muscle Contraction: Alternation of tonic and phasic contractions.
- Explosive-Tonic Muscle Contraction: Overcomes high resistance with rapid force evolution.
- Explosive-Ballistic Muscle Contraction: Maximum force applied to a relatively light load.
- Explosive-Reactive-Ballistic Contraction: Maximum force in response to strong muscle extension.
- Acyclic Speed: Power enacted in response to inertial resistance.
- Cyclic Speed: Work-force repetition rate with maintained performance.
Sexual Differences
Due to testosterone’s anabolic effect:
- Women have approximately 75% of men’s muscle cross-section and 2/3 of their strength, with twice the adipose tissue. Trunk muscle strength shows no significant difference.
Muscle Fibers
- Slow Twitch (ST): Slow, red (more myoglobin), postural.
- Fast Twitch (FT): Fast, white, dynamic.

Gestural Representation Methods
occupy a priority place start training. Depending on age, intellectual capacity and the level reached by the coordination capacity,outstanding for its effectiveness: · Method of visual information: perfectly suited for the beginner athlete, for the development of gesture representation, if any, is essentially a visual mechanism. Contrary to what happens to the advanced athlete, it does not involve only a small part of the kinesthetic elements as important in the representation of motion. · Method of verbal information: may precede the visual method, used in parallel with the same or later. In any case, states, and classifies the gesture to be performed. Methods based on variation and combination: · Variation of the position and start position for the year (departures varied) .- Variation of conditions of initiation of movement or play. · Combinations gestural skills (once fully mastered the skill). · Variation technique exercise performance. · Increased difficulty(complexity) for the year. · Adding simple or complex movements the basic exercise. · Variation of the dynamics of motion (speed and rhythm executive; variation of the usual loads using implements overloaded or not). · Variation the spatial structure of the gesture (varying soil structure, changes in the dimensions of the playing surfaces, etc). · external variations (surfaces, weather …). · Execution of the exercises in unusual conditions. · Variation uptake information (improving it with the increase or reduction of the information presented, both visual, auditory, static-dynamic, tactile and kinesthetic.: Ordering variety of equilibrium in a static and dynamic on the ground or on elevated foundations.
