Activity and Fatigue Part 1

These flashcards summarize key vocabulary and concepts from the lecture on activity and fatigue, focusing on the effects of exercise, fatigue types, chronic fatigue syndrome, and physiological consequences.

Benefits of exercise

Includes heart health, muscle atrophy prevention, improved insulin sensitivity, release of endorphins, enhanced lung and brain function, improved self-esteem, and lower mortality rates.

Activity tolerance

The amount of physical activity one can perform without causing harm to oneself.

Fatigue

A subjective feeling characterized by a lack of energy, often compared to a battery that needs recharging.

Acute fatigue

Fatigue with rapid onset lasting less than 4 weeks, often due to short-term sleep loss or heavy exercise.

Chronic fatigue syndrome (CFS)

A vague, non-specific syndrome characterized by multiple self-reported symptoms that lead to disabling fatigue.

Myalgic Encephalomyelitis (ME)

A chronic fatigue syndrome with symptoms including muscle aches, joint pain without swelling, severe headaches, and recurring sore throat.

Chronic fatigue

Fatigue lasting more than 6 months, associated with chronic diseases such as fibromyalgia and depression.

Postural hypotension

A significant drop in blood pressure when a person stands from a sitting or lying position, leading to dizziness.

CFS treatment interventions

Includes education about the condition, emotional support, symptom management, and structured activity programs.

Virchow's Triad

Three factors that contribute to increased risk of DVT: venous stasis, hyper-coagulability, and blood vessel damage.

Respiratory effects of immobility

Decreased tidal volume, forced vital capacity, and residual volume, leading to mucus pooling and respiratory difficulties.

Musculoskeletal consequences of immobility

Includes muscle atrophy, contractures, and weakening of tendons and ligaments due to lack of movement.
