Physiological Changes with Ageing and Exercise Benefits
Q1. Elucidate Physiological Changes Due to Ageing?
Ans. The physiological changes that take place are mentioned below:
- Change in Nervous System: During ageing, reaction time and movement time slow down with increasing age. The brain shrinks, the size of its network and its blood flow decreases.
- Change in Gastrointestinal System: With increasing age, there is a reduction in the production of Hydrochloric Acid, Digestive Enzymes, and Saliva. These changes may result in delayed emptying of the stomach
Defining Motor Skills, Movement, Coordination, and Balance
Movement Definition
Movement: A sequence of concrete actions through processes of muscle contractions and joint movements.
Motor Task Explained
Motor Task: An activity with a specific purpose performed under particular conditions for the development of a skill. Tasks generally have three parts:
- Perception
- Decision
- Implementation
There are two main types of tasks:
- Psychomotor: The motor action is performed alone.
- Sociomotor: The motor action is carried out in the presence of, or interaction with, others (
Fundamentals of Physical Education: Concepts and Principles
Fundamentals of Physical Education
The action teaches us and falls into the broad field of sports. There are three physicomechanical fields: recreational, educational and didactic competitive, and rehabilitation. Teaching involves how to teach. The difference between a professor involves two stages: initial information, knowledge of results, and methods (how to carry out an action in a structured manner), and methodology.
Methodology
This is the part that deals with the didactic teaching methods to

Common Sports Injuries
- Sprain (*esguince*)
- Consists of stretching or tearing one or various ligaments.
- Dislocation (*dislocación*)
- Occurs when two joint surfaces lose contact due to displacement.
- Meniscus Injuries (*lesiones de menisco*)
- The menisci are fibrocartilaginous structures reducing joint friction. Knee menisci are most commonly injured, usually when performing a rotation during flexion and weight-bearing.
- Synovitis (*sinovitis*)
- Inflammation of the synovial membrane, often caused by recurrent
Understanding Force, Inertia, and Fitness Testing
Understanding Force and Motion
Force: A push or pull action applied upon an object.
Inertia: An object in motion stays in motion at the same speed and in the same direction, and an object at rest stays at rest unless acted upon by an external force.
Force (N) = mass (kg) x acceleration (a)
- Mass: The quantity of matter in a body.
- Acceleration: Rate at which an object changes speed.
Acceleration and Newton’s Third Law
Acceleration: An object will accelerate when acted upon by an external force. The acceleration

Basic Futsal Principles
Objectives
Get the ball into the opposing goal. The team with more goals wins.
Playing Field
The dimensions are identical to those of field handball: 40m x 20m.
Material
The ball has a diameter of 61-63 cm and weighs between 410 and 430g.
Duration
Two halves of 20 minutes with a 10-minute rest period.
Players
The team consists of five field players (four outfield players and a goalkeeper). Each has a specific place on the field:
- Pivot: The most advanced player, who must be strong and
