- many problems associated with cardiovascular disease are related to atherosclerosis (often starts from childhood) - atherosclerosis is a progressive disease that results in narrowing of arteries due to the buildup of fatty plaque within the inner wall of an artery - three major classes of risk factors for atherosclerosis: 1. genetic 2. diet 3. physical inactivity
approach for obese/overweight individual
- most people dont need their PT to tell them about their overweight/obesity - that doesn't mean we dont discuss diet and nutrition - consider framing the conversation around well-being, performance, gut health etc. Find what is relevant for your patient - You can discuss overweight/obesity but avoid being just another clinician who tells the patient to lose weight - E.g. increased lean muscle mass can be beneficial even if weight remains the same
Develop Discrepancy
- motivation for behavior change occurs when patient perceive discrepancies between their current situation and their hopes for the future. - help patient focus on how current behavior isn't consistent with the desired behavior - a method of this is exploring the advantages and disadvantages of behavior change.
Supporting lifestyle change
- motivational interviewing - express empathy - support self-efficacy - develop discrepancy - roll with resistance

anaerobic glycolysis
- requires energy in early investment phase to generate energy in the generation phase. - muscles store a limited amount go glycogen. Glycogen consists of long strings of glucose sugar molecules, when split become pyruvate and energy to create ATP - pyruvate is transformed into lactate with a hydrogen ion -net product depends on whether energy is produced from a glucose or a glycogen molecule

plasticity
- tendency of soft tissue to assume a new and greater length because of alterations
muscular endurance
- the ability of a muscle to contract repeatedly against an external load, over an extended period of time - the muscles adapt to endurance training by increases in their oxidative and metabolic capacities, which improves oxygen delivery and use - for many patients with impaired muscle performance, endurance training has a more positive impact them strength training
What is functional stability (dynamic stability)?
- the ability of the joint to remain stable during physical activity
Atherosclerosis process
- the atherosclerosis process is caused by inflammation initiated within the inner lining of the artery - inflammation is in response to tissue injury that involves the recruitment of white blood cells (leukocytes) to the affected site - Normally, the endothelial cells that line the inner surface of the artery do not support the binding of leukocytes - however, when the endothelium is activated by such risk factors, the endothelium generates adhesion molecules on its surface that can bind readily to leukocytes in the blood - once bound to the adhesion molecules, the endothelial cells secrete chemokine that attract the monocytes to enter the intimate, where they mature into macrophages - the macrophages develop scavenger receptors on their surface that ingest large amounts of modified LDL cholesterol - the macrophages become loaded with fatty droplets and develop into foam cells. These foam cells and T cells make fatty streak, which is the earliest form of atherosclerotic plaque - as process continues, macrophages multiply due to growth factors they produce, and size of plaque increases - some smooth muscle cells in middle layer of artery move to the the top layer of the inter where they multiply, and with connective tissue form a fibrous matrix cap over the fatty core of the plaque - foam cells release inflammatory signals that lead to the digestion and weakening of the fibrous matrix cap. if cap ruptures, chemicals released interact with factors in the blood to form a clot
Estimated Average Requirement (EAR)

progression
- time, frequency intensity
Overload principle
- to improve muscular performance, a resistance load that exceeds the metabolic capacity of the muscle must be applied. - muscle must be challenged to perform at a level greater than that to which is it accustomed - strength training: the amount of external resistance applied to the muscle is incrementally and progressively increased - endurance training: emphasis is place don increasing the time over which a muscle contraction is sustained or the number of repetitions performed increases
sensory organization
- to reduce or destabilize the visual inputs, have the patient close his or her eyes, wear prism glasses, or move eyes and head together during the balance activity - to decrease reliance on somatosensory cues, patients can narrow the BOS, stand on foam, or stand on an incline board
principles of plyo
- train movement patterns in isolation and break the desired functional movement into smaller components - isolation first, if it cannot perform dont progress - neuromuscular overload: progressive overload - spatial overload: increase distance or height (ROM) - Temproral overload: faster is better - intensity - volume - frequency - recovery - specificity
reversibility principleq
- use it or lose it - detraining, reflected by reduction in muscle performance. begins a week or two after cessation of resistance exercises and continues until training effects are lost in an average of 4 weeks - it is imperative that gains in strength and endurance are incorporated into daily activities as early as possible in a rehabilitation program
Concepts to understand
