  • Lesson 2 • Properties of Water

    Covers buoyancy, drag, lift, and propulsion forces acting on the human body. Provides the scientific basis for explaining stroke mechanics to students.

  • Lesson 3 • Cardiovascular and Respiratory Responses

    Examines how immersion, breath control, and exercise intensity affect heart rate and oxygen uptake. Guides safe exercise intensity selection for diverse populations.

  • Lesson 4 • Common Aquatic Injuries and Prevention

    Identifies overuse injuries, shoulder impingement, and ear conditions common in swimmers. Connects biomechanical instruction to long-term athlete health.

Chapter 4See details

Emergency Action and Risk Management

  • Lesson 1 • Emergency Action Plan Development

    Covers EAP components, role assignments, communication protocols, and drill scheduling. Ensures instructors can activate and execute a coordinated emergency response.

  • Lesson 2 • Risk Identification and Hazard Control

    Teaches systematic hazard identification, risk rating, and control hierarchy for aquatic facilities. Establishes the proactive safety mindset required before any lesson begins.

  • Lesson 3 • CPR, AED, and First Aid Integration

    Reviews CPR and AED protocols and their integration into aquatic emergency response. Reinforces certification requirements instructors must maintain throughout their careers.

  • Lesson 4 • Aquatic Rescue Techniques for Instructors

    Introduces reaching, throwing, and wading rescues appropriate for instructor-level response. Distinguishes instructor rescue responsibilities from lifeguard duties.

  • Lesson 5 • Incident Documentation and Reporting

    Covers incident report writing, near-miss documentation, and post-incident review processes. Builds the administrative skills needed to fulfill legal and organizational obligations.

Chapter 5See details

Stroke Mechanics and Skill Progressions

  • Lesson 1 • Breaststroke Technique and Progression

    Analyzes the simultaneous pull, kick, and glide cycle unique to breaststroke. Addresses the most technically complex stroke for beginner swimmers.

  • Lesson 2 • Backstroke Technique and Progression

    Covers supine body position, alternating arm recovery, and kick coordination. Builds on freestyle body position concepts introduced in the previous section.

  • Lesson 3 • Survival and Elementary Strokes

    Covers sidestroke, elementary backstroke, and treading water as survival skills. Ensures instructors can teach life-saving movement patterns beyond competitive strokes.

  • Lesson 4 • Freestyle Technique and Progression

    Breaks freestyle into body position, kick, pull, and breathing components with drill sequences. Establishes the foundational stroke taught first in most learn-to-swim programs.

  • Lesson 5 • Butterfly Technique and Progression

    Teaches the dolphin kick, simultaneous arm pull, and undulation rhythm of butterfly. Presented last due to its high coordination and strength demands.
