Movement: In the context of sports biomechanics, movement refers to any change in the position of a body or its segments.
Types of Movement: Human movement is incredibly diverse and can be categorized based on various factors:
- Linear Motion (Translation): When all parts of the body move in the same direction and at the same speed. Example: A sprinter running on a straight track.
- Angular Motion (Rotation): When a body or its segments move around a fixed axis or point. Example: A gymnast performing a giant swing on the high bar.
- General Motion: A combination of linear and angular motion. Most human movements fall into this category. Example: A soccer player dribbling the ball.

Causes of Movement - Forces and Torques

Force: A push or pull that can cause a change in the motion (acceleration or deceleration) or shape of an object.
- Internal Forces: Generated within the body by muscles contracting. These forces are responsible for initiating and controlling most human movements.
- External Forces: Act on the body from the outside. Examples include gravity, friction, air resistance, and contact forces from other objects or individuals.
Torque: A rotational force or a force that causes an object to rotate around an axis.
- Moment Arm: The perpendicular distance between the line of action of a force and the axis of rotation. The greater the moment arm, the greater the torque produced by a given force.

Key Points:

Newton's Laws of Motion: The foundation of understanding the relationship between forces and motion.
- First Law (Inertia): An object at rest stays at rest, and an object in motion stays in motion unless acted upon by an external force.
- Second Law (Acceleration): The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. (F = ma)
- Third Law (Action-Reaction): For every action, there is an equal and opposite reaction.
Center of Gravity (COG): The point around which a body's weight is evenly distributed. The COG's position influences stability and movement patterns.

Unit 2: Sports Psychology

Introduction

Definition: Sports psychology is the study of how psychological factors influence sports performance and how participation in sports and exercise affects psychological and physical factors. It aims to understand and enhance the psychological well-being and performance of athletes.
Key areas: Motivation, goal setting, anxiety management, concentration, coping with injuries, team cohesion, and other related psychological aspects.

Motivation and Goal Setting in Sport

Motivation: The internal and external forces that drive an individual to initiate and persist in an activity.
- Types: Intrinsic motivation (driven by internal factors like enjoyment and satisfaction) and extrinsic motivation (driven by external factors like rewards and recognition).
Goal Setting: The process of establishing specific, measurable, achievable, relevant, and time-bound (SMART) objectives to enhance performance.
- Benefits: Increased focus, effort, persistence, and self-confidence.
- Types of Goals: Outcome goals (focus on the end result), performance goals (focus on personal improvement), and process goals (focus on the actions necessary to achieve performance goals).

Anxiety in Sports

Anxiety: A feeling of worry, nervousness, or unease, typically about an imminent event or something with an uncertain outcome.
- Types: Cognitive anxiety (worrying thoughts and negative self-talk) and somatic anxiety (physiological responses like increased heart rate and muscle tension).
- Effects: Can either facilitate or hinder performance depending on the level of anxiety and the individual's ability to manage it.

Concentration in Sports Performers

Concentration: The ability to focus one's attention on relevant cues and maintain that focus over time.
- Key Components: Selective attention (focusing on relevant stimuli), sustained attention (maintaining focus over time), and situational awareness (understanding the broader context).
- Techniques to Enhance Concentration: Mindfulness, meditation, visualization, and self-talk.

Helping Athletes to Cope with Injury

Psychological Impact of Injury: Can lead to a range of emotional responses like anger, frustration, sadness, and fear. It can also affect self-esteem and motivation.
Coping Strategies: Setting realistic goals, maintaining a positive attitude, seeking social support, and using relaxation techniques.
Role of Sports Psychologist: Assist athletes in developing coping skills, managing emotions, and maintaining motivation during the rehabilitation process.

Team Cohesion in Sports

Team Cohesion: The degree to which members of a team feel connected and committed to one another and to the team's goals.
- Types: Task cohesion (shared commitment to achieving the team's objectives) and social cohesion (interpersonal attraction and liking among team members).
- Benefits: Improved communication, cooperation, coordination, and overall team performance.
- Strategies to Enhance Cohesion: Team-building activities, clear communication, shared decision-making, and establishing a positive team culture.
