Study Notes
Aerobic Programs for Beginners
- Walking is a good starting aerobic exercise, easy to maintain, suitable for group activities, and helps build stamina for clients with low activity levels. Gradually adding other exercises is possible without overexertion.
- Swimming is a more challenging aerobic exercise requiring skill. Water exercises provide psychological benefits, masking physical imperfections and providing support, benefiting disabled, obese, elderly, and pregnant individuals by reducing joint strain.
- Water's buoyancy and resistance increase energy expenditure without straining joints.
- Aerobic sessions should last 20-60 minutes, or be broken into 10-minute segments.
- Begin with low intensity, short bouts (e.g., 5 minutes) for sedentary or deconditioned clients, increasing gradually. Multiple, short daily sessions are beneficial for deconditioned clients.
- Aim for 77-90% of maximal heart rate or 60-80% of heart rate reserve during aerobic activity. Daily caloric expenditure should be 150-400 calories.
- For weight loss, 2000+ weekly calories burned is recommended (5 days a week, 45 minutes per session).
- Calorie expenditure is not the ideal measure of exercise effectiveness. Heart rate is a better indicator, accounting for participant skill and coordination (experienced swimmers expend less energy for the same pace compared to inexperienced swimmers with inefficient strokes).
Types of Muscle Actions
- Concentric and eccentric muscle actions are the most effective in training programs.
- Concentric actions produce force to overcome external load and shorten the muscle.
- Isometric actions exert force without changing muscle length.
- Eccentric actions produce force while the muscle lengthens—it is the resistance of the movement.
Proper Positioning
- Correct body positioning during exercise prevents injury and maximizes results.
- Maintain a neutral spine (slight inward curve at neck and lower back, slight outward curve at thoracic spine).
- Keep shoulders back and away from ears, square hips, and avoid hyperextension of a joint.
Posture and Movement Training
- Posture is the alignment and function of the kinetic chain, allowing smooth, safe movement controlled by the central nervous system.
- Posture is dynamic and not just a static measurement.
- Deviations from proper posture change the center of gravity and affect kinetic chain function and efficiency.
- Improper posture increases risk of joint degeneration, tissue stress, and injury.
- Functional strength is the neuromuscular system's ability to perform dynamic muscle actions in all planes of motion.
- "Postural equilibrium" is the starting/ending position, maintained by proper muscle length and tension in force couples.
- Postural distortion patterns are predictable compensations for muscle imbalances (compensations occur if core muscles are weaker than ideal).
Plyometrics
- Plyometrics is used for well-conditioned clients and athletes for speed, strength, power, endurance, flexibility, and coordination training.
- It utilizes the elastic properties of muscles to increase force.
- It involves a strength-shortening cycle with rapid stretching (eccentric actions) followed by shortening (concentric actions) of the muscle. It is sports specific, and used for the entire body, not just lower extremities.
