Definition and characteristics of muscular strength in physical education. What is strength and how does it work and what types of strength do we know.Strength is the individual’s ability to overcome or counteract an external load with muscular effort .It is a fundamental skill for achieving good performance in almost all sports.
TYPES OF STRENGTH
There are three ways to express strength:
- Maximum strength
The ability of a muscle to express the maximum possible tension. This tension can be achieved by:
– Moving a load (concentric muscular action)
– Trying to move an invincible load (isometric muscular action)
– Braking the movement of a very high load (eccentric muscular action) - Fast strength
The ability to express high muscular tension in the shortest possible time. This strength is also called explosive .
It is a fundamental strength in so-called power activities, which require acceleration skills (sprints, throws), elevation skills (jumps, vaults) and in all movements that require speed of execution of the technical gesture (serve in tennis, smash in volleyball, lunge in fencing). - Enduring strength
The ability to express high tensions for a relatively long time. A muscle group or the entire organism resists the onset of fatigue in actions that require prolonged and repeated muscular effort (in the final sprint of a cyclist or in the effort of paddling in a canoe).
You can perform the exercises with two types of load:
- Naturally loaded
The weight of your own body acts as the only resistance to overcome - With overloads
A load (e.g. dumbbells, barbells, etc.) is added to your body weight to increase the effort of muscle contraction.
CONCENTRATION REGIMES
Here are three types of concentration regimes during training:
- Concentric regime
It is used to increase muscle mass. During contraction, the muscles come closer together, causing parts of the body to move. An example is weight lifting. - Eccentric regimen
This occurs when you slowly give way under a very high overload. An example is the slow bend on one leg and the return to the standing position using both limbs. - Isometric regimen
This occurs when you develop high muscle tension, maintaining the body or part of it in a certain position. An example is when you assume a position with your elbows bent at 90° on a bench and hold it until fatigue.
