Musculoskeletal System: Bones, Joints, Muscles, and More
Musculoskeletal System
The musculoskeletal system supports the body, facilitates movement, and protects internal organs. It comprises two main systems:
Skeletal System
The skeletal system is the passive part of the locomotor system, forming an internal, mobile frame composed of bones, joints, and ligaments. Its functions include:
- Enabling body movement and providing shape
- Anchoring skeletal muscles
- Storing calcium and phosphorus
- Producing blood cells in the bone marrow
The skeleton is divided into the head,

Knowledge Interaction and Individual Implementation
Each student, after receiving initial information, provides a motor response. Knowledge of performance and results should be provided individually, as much as possible.
- Prioritize attention to students with the greatest needs.
- Provide positive reinforcement to students performing well or nearly well.
- Devote more time to those requiring corrections, shifting priorities and attendance to individuals practicing proper exercise execution.

1 – Prehistory and Antiquity
The aim of exercise is heading for survival and the struggle for life.
Prehistory
Physical activities are demonstrations that accompany man from his appearance on earth. There were two forms of physical culture:
- Peoples war: Exercises to combat the fierce and as preparation for war.
- Sedentary peoples: Exercises mix of magic and religion, with those who fight against the mysterious forces that they considered the causes of illness and death.

Resistance and Strength Training for Athletes
Resistance Training
Definition
Resistance is the ability to make an effort to a greater or lesser extent for as long as possible. Two types of resistance training develop aerobic endurance (low intensity and long duration) and high-intensity anaerobic work.
Types of Anaerobic Work
Depending on its duration, anaerobic work may be lactic anaerobic endurance (long-lasting) or alactic anaerobic (short-lasting).
Continuous Methods
- Exercise of long duration and low intensity.
- Allows a variety of routes and terrains.
Laws of Reflexes and Conditioning
1st Law of the Door
It is an objective factor (all stimuli). The threshold sets a minimum quantity which must be a stimulus to generate a reaction. It is characteristic of each kind – depends on other stimuli.
2nd Law of Latency
It is an objective factor. Latency is the interval of time between stimulus and response. E ‘R (‘ = latency). If there is an immediate response, it is called Interrupt (because it is not possible). The more intense the stimulus, the lower the latency.
3rd Law of Magnitude
A greater
