When would plyometrics be used with a patient? | during end of rehab, minimum protection phase |
How do plyometrics work? | it uses the stretch reflex to increase muscle contraction speed. By increasing load and speed then greater firing frequency of the muscle spindle makes stronger muscle contraction |

Lymphatic helps the immune system by | destroying pathogens and filtering waste |
Lymphatic system works with the circulatory system to | deliver nutrients, oxygen, and hormones from blood to the cells that make up the tissues of the body |
Important protein molecules are created by cells in the tissue. Because these molecules are too large to enter the cappilaries of the circulatory system, these protein molecules must be transported by the | lymph to the blood stream at the terminus |
In lymphedema affected tisses, the lymph is unable to | drain properly |
If lymph cannot drain properly, protein-rich lymph becomes | stagnant, making lymphedema tissues prone to infection |
Intercellular fluid is found where | between cells or outside cells |
Intracellular fluid is | inside the cell |
What is delivered to cells by intercellular fluid | nutrients, oxygen, and hormones |
As fluid leaves a cell, what does it take with it | cellular waste products and protein cells |
90& of this tissue fluid flows into the venules | intercellular/interstitial fluid |
When interstitial fluid enters the venules, it enters venous circulation as | plasma and continues to the circulatory system |
10% of the fluid left is known as | lymph |
This system does not have a pump to aid in its flow and relies on muscle contraction | lymphatic system |
As fluid travels through the lymp systems, | it passes through lymph nodes where it is filtered |
70% of specialized lymphatic cappilaries are located | near the skin |
Deep lymphatic cappillaries | surround most of the body's organs |
blind-ended tubes that are only a single cell in thickness arranged in slightly overlapping pattern like shingles on a roof | lymphatic capullaries |
lymphatic cappilaries join together to form a | mesh-like network of tubes that are located deeper in the body |
have one-way valves to prevent backflow of fluid | lymphangions |
Because there are only about 600-700 lymph nodes present in the average human body, lymphedema mght occur if they are damaged or destroyed because they | do not regenerate |
Afferent carry lymph | into the node |
Efferent carry lymph | out of the node |
Damage to lymph vessels disturbs | flow |
When lymphatic tissues or lymph nodes have beed damaged, destroyed or removed, lymph cannot | drain normally from the affected area. When this happens excess lymph accumulates and results in the swelling that is characteristic of lymphedema |
treatment of lymphedema is based on the natural structures and flow of lumph. Affected drainage area determines pattern of | manual lymph drainage or self massage |
what does MLD (manual lymph drainage) do? | stimulates flow from one area to another and encourages formation of new lymph drainage pathways |
worn between treatments to help control swelling by providing pressure that is needed to encourage the flow of lymph into the capillaries | compression garments, aids, and/or bandages |
prescribed by the therapist, it is another way to encourage flow into cappilaries | self-massage or simplified lymphatic drainage |
an important treatment of lymphedema because the movements of the muscles stimulate the flow of lymph into the capillaries | exercise |
structurally, lymph vessels are very | delicate, thus they are easily damaged |
List benefits of aerobic exercise after the activity: | increased mitochondira, increased myoglobin, increased mobilization of fats and carbs, hypertrophy of type I, decrease HR and submaximal HR, increase blood volume and increase hemoglobin, decrease systolic and diastolic BP, increase ability to extract O2 |
aerobic exercise should be what intensity and duration | long duration low intensity |
Age Adjusted Max Heart Rate | 220-age= number then decide what percentage you should be exercising at. |
Karvonen formula for HR max | use max HR from MHR minus resting HR, then multiply by 50% for low end and 85% for high end |
