History of Physical Activity and Sports
1. What is Physical Culture?
The origins of physical culture can be traced back to primitive times, where “body culture and physical activity” manifested primarily through dance and play. These activities, passed down through generations, focused on efficiency, adaptability, and capacity rather than social interaction or cultural advancement.
2. When Did Physical Education Begin?
Formal physical education emerged in the mid-eighteenth century in Europe, coinciding with the development of structured

Knee
Structure
The knee joint comprises the tibiofemoral (trochlear bicondylar) and patellofemoral articulations. Key components include the joint capsule, menisci, trabecular system, ligaments, and tendons.
Osteokinematics
Active Movements:
- Flexion: 140° of the tibia on the femur
- Extension: 180° of the tibia on the femur
- Medial Rotation of the tibia on the femur
- Lateral Rotation of the tibia on the femur
Close Packed Positions:
- Patellofemoral: 30° to 60° flexion
- Tibiofemoral: Full extension (180°) or
Understanding Agility in Gymnastics and Other Sports
What is Agility?
Agility is the ability to perform non-cyclic movements—in different directions and senses—quickly and accurately.
Factors that Determine Agility
Several factors influence agility, including physical and psychomotor qualities:
- Physical Factors: Coordination and balance
- Psychomotor Qualities: Flexibility, speed
The ideal combination of these qualities results in good agility.
Key Components of Agility
- Speed: Enables quick movements.
- Flexibility: Allows for a wider range of motion, which
Burns and Other Injuries: First Aid and Treatment
Burns: Injury Caused by Heat
Assessing Severity
Several factors determine the severity of a burn:
- Depth: Deeper burns are more serious.
- Extension: Larger burns are more threatening.
- Location: Burns on the eyes, genitals, or natural orifices are more serious.
- Age: Children and the elderly are most at risk.
- Infection: Infection can worsen the damage caused by the burn.
Burn Depth Classification
- First Degree: Erythema (redness) affecting the epidermis.
- Second Degree: Blisters with fluid affecting the epidermis

Epileptic Seizures
Symptomatology
A seizure occurs when abnormal electrical activity in the brain causes an involuntary change in body movement or function.
Simple Partial Seizures
These seizures involve clinical manifestations (symptoms or signs of motor, sensory, autonomic, or psychic) and electroencephalographic shock, reflecting a system of neurons located in part of the cerebral hemisphere without alteration of consciousness.
Complex Partial Seizures
These seizures involve a compromised level of
