Study Notes

Elbow Anatomy

The elbow joint connects the humerus, ulna, and radius bones.
The elbow allows for flexion, extension, pronation, and supination of the arm.
The humerus has two articular surfaces: the Capitulum and the Trochlea.
Ligaments supporting the elbow joint:
- Annular Ligament surrounds the head of the radius.
- Medial Collateral ligament has two bands, one anterior and one posterior.
- Lateral collateral ligament extends from the lateral epicondyle to the annular ligament.
The joint capsule (synovial membrane) provides elbow stability.

Shoulder Anatomy

The shoulder joint (glenohumeral joint) connects the scapula and the humerus.
It is a ball and socket joint, allowing for high mobility but compromising stability.
The head of the humerus articulates with the glenoid cavity of the scapula.
The articulating surfaces are covered with hyaline cartilage.

Leg Muscles

Quadriceps Femoris: Responsible for knee extension and hip flexion (for Rectus Femoris).
- Individual Muscles:
  - Rectus Femoris
  - Vastus Medialis
  - Vastus Lateralis
  - Vastus Intermedius
Gastrocnemius: Plantar flexes the foot and flexes the knee.
Soleus: Plantar flexes the foot.

Common Leg Injuries

Anterior Cruciate Ligament (ACL) Injury: Occurs with a "plant and twisting" motion. The ACL prevents anterior translation of the tibia relative to the femur.
Medial & Lateral Collateral Ligament Injuries:
- MCL injuries occur with inward landing forces.
- LCL injuries occur with outward landing forces.
Ankle Sprains: Occur when the ankle rolls. Classified into three grades, based on severity:
- Grade 1: Ligaments are minimally affected (bruising, inflammation).
- Grade 2: Ligaments are stretched but not torn (moderate bruising, inflammation).
- Grade 3: Ligaments are completely torn (severe bruising, inflammation).

Fatigue and Training Principles

Fatigue: Inability of muscles to maintain strength during exercise, caused by ATP depletion and lactic acid accumulation.
Training Principles:
- Specificity: Adaptations are specific to the type of training stimuli.
- Progressive Overload: The stimulus must progressively increase to induce adaptation.
- Reversibility: Adaptations are lost if training is discontinued.
- Individualization: Adaptations vary between individuals.
- Variation: Continuous stimulus can lead to accommodation, requiring changes in training approaches.
- Recovery: Sufficient recovery is essential for training effects.
- Diminishing Returns: High-level athletes may see diminishing returns with further training.

Load Management (SAID Principle)

SAID (Specific Adaptation to Imposed Demand): Applies to strength, muscular endurance, and skill learning.
Internal Load: Individual's perceived exertion and physiological response to training.
External Load: Objective measures of training, like repetitions, sets, and weight.
Rate of Perceived Exertion (RPE): Subjective measure of effort during exercise.
Acute Workload: Short-term measure of fatigue.
Chronic Workload: Long-term measure of fitness.
Acute/Chronic Workload Ratio: Measure of short-term load (fatigue) relative to long-term load (fitness).

Leadership Styles

Transactional Leadership: Focuses on rewards and punishment.
Laissez-faire Leadership: Lack of leadership or involvement.
Autocratic Leadership: Directive and task-oriented.
Democratic Leadership: Collaborative and athlete-centered.
Transformational Leadership: Vision-driven with a focus on values.
- Characteristics:
  - Inspirational Motivation
  - Idealized Attributes
  - Idealized Behaviors
  - Individualized Consideration
  - Intellectual Stimulation

Coaching and Communication

Coaching Guidelines for Children: Inclusive focus on the child and teaching fundamental movement skills.
Coaching Guidelines for Young Adolescents: Teaching competition rules.
Communication Modalities:
- Verbal (audible communication)
- Non-verbal (visible and audible communication)
Listening Guidelines:
- Focus on the speaker.
- Listen for content and emotions.
- Be attentive, supportive, and genuine.
- Summarize key points.
