Which statement best describes inactive posture?
Which statement best describes inactive posture?
- It includes actions such as walking and running.
- It involves maximum force generation from various muscle groups.
- It is characterized by reduced muscular activity and is suitable for rest. (correct)
- It requires coordinated muscle activity to maintain stability.

What is a potential effect of poor posture on the body?
- Enhanced digestive efficiency.
- Decreased pressure on the spine and surrounding structures.
- Increased risk of falling due to balance issues. (correct)
- Improved joint mobility and flexibility.
What distinguishes dynamic posture from static posture?
What distinguishes dynamic posture from static posture?
- Static posture requires more energy than dynamic posture.
- Dynamic posture involves movement of body segments, while static posture does not. (correct)
- Static posture is the preferred position during exercise.
- Dynamic posture is focused on maintaining alignment without movement.

Study Notes
Definition of Posture
- Posture refers to the body's position, whether supported during inactivity or through coordinated muscle action for stability.
- Inactive posture is assumed during rest or sleep, minimizing essential muscle activity.
- Active posture involves the use of multiple muscles to maintain static or dynamic positions.
Types of Postures
- Static Posture: Body segments aligned in specific positions; includes standing, sitting, lying, and kneeling.
- Dynamic Posture: Involves movement of the body or its segments; includes activities like walking, running, jumping, throwing, and lifting.
Posture and Health
- Poor posture contributes negatively to health, stressing joints and leading to various health issues.
Effects of Faulty Posture
- Increases spinal pressure, leading to injury or degeneration.
- Causes neck, shoulder, and back pain.
- Decreases overall flexibility.
- Impairs joint movement and balance, increasing fall risk.
- Harms digestion and induces breathing disorders, impacting heart health.
- In women, can disrupt core muscles, leading to incontinence or pelvic organ prolapse.
Age-Related Postural Changes
- Common changes include thoracic hyperkyphosis, loss of lumbar lordosis, and decreased plantar arch.
Postural Assessment
Sagittal Plane (Lateral View)
- Normal Posture: Erect head, retracted shoulders, normal spinal lordosis/kyphosis, neutral pelvis, extended knees.
- Faulty Posture: Forward head, rounded shoulders, flattened/hyperlordotic cervical or lumbar spine, anterior/posterior pelvic tilt, hyperextended knees.
Frontal Plane (Anterior View)
- Normal Posture: Head in mid position, level shoulders, straight spine, level pelvis, physiological valgus knees, normal medial arch.
- Faulty Posture: Tilted/rotated head, dropped shoulder, scoliosis, dropped pelvis, knock knees/bow legs, flat foot.
Frontal Plane (Posterior View)
- Normal Posture: Mid position head, level shoulders, no scapular winging, straight spine, level pelvis, physiological valgus knees, neutral foot.
- Faulty Posture: Tilted/rotated head, dropped shoulder, scapular abduction/adduction, scoliosis, dropped pelvis, knock knees/bow legs, foot deformities like calcaneovalgus/varus.
