BIOMOTOR ABILITIES AND THE METHODOLOGY OF THEIR DEVELOPMENT

Biomotor Abilities

Biomotor abilities are the foundations of ability of an individual to perform an exercise.

– strength, endurance, speed, coordination and flexibility.

The contribution of the biomotor abilities to the attainment of high performance is determined by 2 factors:

1.The ratio between them as a reflection of the specifics of the sport and,

2. By the level of development of each ability according to its degree of participation in performing the sport/event.

STRENGTH TRAINING

• Strength: The ability to apply force or the neuro-muscular capability to overcome an external and internal resistance.

• Force: May be referred to as both a mechanical characteristic and a human ability. F= M.A

Following a strength training program a muscles enlarges itself or hypertrophies as a result of the following factors:

1. the number of myofibrils (the slender threads of a muscle fiber) per muscle fiber increases (hypertrophy)

2. an increased capillary density per muscle fiber

3. an increased amount of protein

4. and an increased total number of muscle fiber

Strength Magnitude

Intermuscular co-ordination: Adequate co-ordination between muscle groups are needed in strength training.

Intramuscular co-ordination: An athlete’s force output depends also on the neuromuscular units which simultaneously take part in the task

Types of Muscle Contraction

1. Isotonic contraction

Concentric -muscle length shortens

Eccentric- muscle lengthen negative work

2. Isokinetic contraction equal and constant and full range of motion

3. Isometric contraction no changes in muscle’s length fixed resistance

4. Electrical Stimulation

Factors Affecting Strength Performance

1.Muscle potential

2. The utilization of muscle potential

3. Technique

Types of Strength

1. General strength: the strength of the whole muscular system.

2. Specific strength: the strength of specific (sport related) muscles.

3.Maximum Strength: Highest force that can be performed by the neuromuscular system during a maximum voluntary contraction.

4. Muscular Endurance: The muscle’s ability to sustain work for a prolonged period of time.

5. Power: The ability to perform maximum force in the shortest period of time (elastic power)

6. Absolute strength: The ability of an athlete to exert maximum force regardless of own body weight.

7. Relative strength: The ratio between an athlete’s absolute strength and his/her body weight

RS= AS/BW

8. Strength reserve: The difference between absolute strength of an athlete and the amount of strength required to perform a skill under competitive conditions.

The Methodology of Strength Training

Without weight
individual body

calisthenics, elastic bands cords, partner, and fixed resistance (isometric training

With weight (weight training)
Free weights, universal machines

Special training (Plyometric)

Rules With Free Weight

1. Free weights should be used in connection with other means of training (medicine ball etc)

2. Weight training exercises may use both analytic and synthetic exercises(small group of muscle or a body limb) (several limbs and muscle group)

3. Before working the active limb, the passive segment should be exercised.

4. Before developing muscular strength good flexibility should be developed to avoid eventual joint rigidity.

Methodical Parameters Relevant to Strength Training

• Number of exercises:

– age and level of performance

– needs of the sport

– phase of training

• The load of training

– Supermaximum—100-175%

– Maximum—90-100%

– Heavy---60-90%

– Medium—30-60%

– Low—below 30%

• Repetition: The number of work intervals within one set.

• Set : The total number of repetitions performed before a rest interval is taken.

• The number of repetitions and rhythm of execution: Both the number of repetitions and rhythm or speed of execution are a function of load; the higher the load the lower the number of repetitions and speed of execution.

• The number of sets

• The rest interval and activity during rest

– for maximum strength rest interval should be 2-5 min

– for muscular endurance shorter rest interval

• The total volume of training for strength development.

The Methodical Sequence of Developing a Strength Training Program

1. The coach should select the exercises which will be employed in the program.

2. Test the max. strength in one attempt or one repetition max. (1RM) to determine the athlete’s prime movers 100% strength.

3. According to the characteristics of the sport, athlete’s needs and the type of strength, the range of percentage of loads to be used in training should be determined.

4. Test the athlete’s max. number of repetitions with the selected load

RM(%) / 100 = NR

12(75%) / 100 = 9

5. Develop the training program and apply it in a given phase of training

6. Test the recalculate the max. strength and the number of repetitions per selected percentage of max. strength.

Methods Used to Develop Strength and its Component

1. Characteristics of developing max. strength

2.Characteristics of developing power

• acyclic power

• cyclic power

3. The characteristics of developing muscular endurance

• cyclic muscular endurance

• acyclic muscular endurance

Training Methods For Strength Development

Maximum Strength Methods

• Weight Lifting (isotonic & isometric)

– load increases continuously

(80%-90%-100%-110%)

– load incraeses in steps (progressive)

(80%-80%; 90%-90%; 100%-100%; 110%-110%)

– load incraeses & decreases continually (pyramidal)

(80%-90%-100%-100%-100%-90%-80%)

– wave-like increase of load

(80%-90%-85%-90%-100%-95%-100%-90%)

Isometric Training

1. attempting to lift a weight heavier than one’s potential

2. applying force against immobile objects

3. applying force with one limband opposing it with another.
