Immediate Response to Medical Emergencies and Injuries
Cardiovascular Accidents (Stroke)
A cardiovascular accident, commonly referred to as a stroke, is a sudden interruption in the blood supply to the brain, typically caused by a blood clot or a ruptured blood vessel. This interruption deprives the brain of oxygen and nutrients, leading to brain cell damage or death. Although severe strokes can sometimes lead to cardiac arrest, many people make a full recovery.
Symptoms of Stroke
- Paralysis or weakness, often on one side of the body
- Speech difficulties
Muscle Strength and Speed: Training Principles and Physiology
Muscle Strength and Contraction Dynamics
Defining Strength
Strength: The ability to exert tension against resistance.
Types of Muscle Contractions
Isometric Contraction
A contraction in which no movement occurs in any joint. The muscle retains the same length (Force = Resistance).
Dynamic Contraction
A contraction that results in movement:
- Concentric Isotonic Contraction (F > R): If the muscle decreases length. Example: Raising the weight.
- Eccentric Isotonic Contraction (F < R): If the muscle lengthens.
Pressure Ulcer Stages, Classification, and Treatment Protocols
Understanding Pressure Ulcers (Bedsores)
The term Bum is often used colloquially to refer to the buttocks or, in a medical context, slang for a pressure ulcer (also known as a decubitus ulcer or bedsore) located in the sacral or gluteal region.
For the purpose of classification and management, we will focus on the professional definition of this condition.
Definition of a Pressure Ulcer (PU)
A pressure ulcer (PU) is defined as a localized injury to the skin and/or underlying tissue, usually occurring

Basic Athletic Stance
The stance taken by the player must allow fast reactions to game possibilities. To achieve this:
- Your legs should be separated at shoulder width, with your feet firmly positioned on the floor.
- Your torso should be balanced over both of your legs, slightly bent forward.
- Your arms should be parallel to the ground, with your palms facing your opponent.
Passing and Receiving Fundamentals
This is a basic, and perhaps the most important, part of the game because bounce is often less critical

Core Definitions in Physical Education
Physical Education (EF) aims to assist the individual in the development and refinement of all their capabilities and human potential, through the process of motor and physical interaction with their environment, utilizing human and material resources.
Physical Activity (AF) is any intentional bodily movement, realized by skeletal muscles, which is associated with an expenditure of energy and personal experience, and allows us to interact with the surrounding

Disability
Definition of Disability
Disability is any restriction or lack of ability (resulting from an impairment) to perform an activity in the manner or within the range considered normal for a human being.
Key Points on Disability
- It may be physical, sensory, intellectual, or mental in nature.
- It results from impairments (loss or abnormality of structure or function) and leads to handicap (disadvantage in fulfilling a role in society).
- Examples include paralysis,
