Fitness Components: Resistance, Strength, Speed & Flexibility
Resistance
Resistance is the capacity that allows us to maintain physical effort for a long time and recover more quickly afterward. Several elements influence muscular resistance:
- Type of muscle fiber: fast or slow
- Energy stores
- Ability to remove lactic acid, which causes fatigue
Other systems also play a role:
- Nervous system: Coordination of muscles during movement
- Circulatory system: Amount of oxygen and energy substances in the blood
- Respiratory system: Ability to carry oxygen to the body

Motor Learning and Development
Basic Concepts
Learning and Motor Development
Learning is generally defined as a change in behavior. Motor learning, specifically, is a stable change or modification of motor behavior through practice. We learn through practice. It is crucial to provide children with positive and constructive learning experiences.
Practice, in this context, includes all the methods used to learn a behavior or motor skill. In motor learning, behavior is controlled by the administration,

Pedagogy and Its Relationship with Physical Education
Pedagogy is the science that explains and governs the educational process, from theory to practice. It relates to physical education (PE) as the pedagogy of physical activity—the science governing PE processes.
The relationship between science and PE pedagogy is that the science of physical activity describes the human body, its movements, and adaptation processes, both physiologically and socially.
PE, like any intervention discipline, should

Basic 1: Position Player in Attack
1.1. Without the Ball:
- Marginal Vision: Observe and understand the entire court.
- Feet: Shoulder-width apart, weight distributed mostly forward.
- Legs: Knees bent, low center of gravity.
- Trunk: Straight and leaning forward.
- Arms: Away from the body, bent.
- Head: Upright.
1.2. With the Ball:
- A) Triple Threat: Shooting hand foot forward, arms bent, head up, straight trunk, ball at hip height, be decisive and pressure the defense.
- B) Ball Up: Used to reverse the ball. With the

Mid-Semester Test 1
Section A
Question 1: Needle Electrode Safety
Safety considerations for needle electrodes:
- Use sterile, disposable needles to prevent infection.
- Ensure proper grounding to prevent shocks.
- Avoid needle reuse to prevent cross-contamination.
- Handle with care to prevent injury.
Question 2: Biomedical Signals
A biomedical signal measures physiological activities, such as ECG, EEG, or EMG.
Question 3: Telemedicine and Instrumentation
Telemedicine uses devices like digital stethoscopes, portable

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
