What are the effects on cancer risk of PA in adults?

Up to 25% reduction in breast, colon cancer

What does pre participation screening of PA involve ?

Current and past medical history, drug history, family history, lifestyle factors, special circumstances eg pregnancy, red flags. Questionnaires such as PAR Q +

What are the absolute cardiovascular complications of PA?

MI <2 days
Unstable angina
Uncontrolled cardiac arrhythmia with haemodybamic compromise
Active endocarditis
Symptomatic severe aortic stenosis
Decompebsated heart failure
Acute myocarditis or pericarditis
Suspected dissecting aneurysm

What are some relative contraindications of PA in adults?

Known obstructed left main coronary artery stenosis
Moderate to severe aortic stenosis with uncertain relationship to symptoms
Tachyarrhythmias with uncontrolled ventricular rates
Acquired or advanced complete heart block
Recent stroke or TIA
Resting hypertension >200/110
Significant anaemia
Uncorrectee Hyperthyroidism
Electrolyte imbalance

What are the metabolic effects of PA in children?

Improved serum lipid profile and glucose, Decreased insulin resistance
Improved body composition
Reduced visceral and intra hepatic fat
Maintenance of healthy weight

What effect does PA gave on bone health in children?

Improved bone mineral density and bone structure with weight bearing/ impact activity- 90% of peak bone mass is achieved by 18y so optimising this in adolescence is protective against osteoporosis in adulthood.

What effect does PA have on cognition and mental health in children?

Improved cognitive function and academic outcomes
Improved memory and executive function
Reduced depression
Improved sleep

How can children incorporate PA into their lives ?

In recreation, at school, PE, travel, helping with household jobs, reduce screen time and sedentary time.

What are the absolute contraindications to PA in pregnancy?

Severe Respiratory disease
Severe heart disease
Uncontrolled type 1 diabetes
Placental abruption
Vasa previa
Severe pre eclampsia
Cervical insufficiency
Intrauterine growth restriction
Active preterm labour

What are the relative contraindications to PA in pregnancy?

Mild Respiratory disease Congenital or acquired heart disease Well controlled type 1 diabetes Mild pre eclampsia Preterm premature rupture of membranes Placenta previa after 28 weeks Symptomatic severe eating disorder Multiple nutrient deficiencies Untreated thyroid disease Moderate/ heavy smoking in presence of comorbidities

What PA activities should pregnant women avoid

Avoid excessive heat and humidity eg hot yoga and vigorous activities in these conditions especially in first trimester Exercising at high altitude Scuba diving Contact activities

Why are pregnant women at higher risk of injury?

Hormone related changes lead to ligaments laxity so a thorough warm up and cool down is recommended

Is there any evidence of increased risk of miscarriage, stillbirth, complications of delivery or effect on birth weight as a result of PA?

What are some of the benefits to pregnant women of PA?

Reduced risk of preterm birth Improved maternal health and recovery after delivery Reduced labour and delivery complications Less body pain, back pain after delivery Decreased risk of GDM, improved control of GDM if develops Reduced gestational weight gain- higher maternal BMI between pregnancy is associated with higher risk of complications in subsequent pregnancy Decreased post partum weight gain Decreased risk of hypertensive disorders eg pre eclampsia Reduce depression during and after pregnancy Improved sleep

What factors in elderly people make then more susceptible to injury?

Sarcopenia, lower bone mineral density, degeneration of connective tissues and skin quality, reduced balance and coordination, cognitive impairment

How does our physiology change in older age ?

Reduced maximum heart rate and cardiac output, higher blood pressure, lower maximal aerobic capacity (therefore exercise at a relatively higher intensity), higher residual lung volume, lower viral capacity, increased work of breathing, Decreased lung perfusion quality, reduced glucose tolerance, longer recovery time

What are some of the benefits of PA in older adults?

Reduced morbidity and mortality Improved strength, balance and flexibility Mitigates against age related deterioration Increased independence Reduced progression of disability Decreased risk of falls Prevents osteoporosis Reduced cognitive impairment and dementia Reduced social isolation Reduced depression

What factors may affect PA in disabled adults ?

The level of spinal cord lesion and if it is complete or incomplete Increased risk of conditions that may increase injury risk eg spasticity, joint contracture, pressure ulcers Increased risk of depression and cardiovascular risk factors

What is autonomic dysreflexia?

In people with a spinal lesion at T6 or above there Is a lack of sympathetic response below the level of the lesion which leads to severe hypotension and morbidity and mortality if not treated - can be triggered by simple things like UTIs

What are the benefits of PA in people with disability?

Improved walking, strength and upper extremity function. Improved health related quality of life Improve vascular function in paralysed limbs Reduced shoulder pain

How does MS affect PA?

Fatigue - but improves with fitness Reduced exercise tolerance Maximal aerobic capacity, heart rate and blood pressure response to activity reduced Lower muscle strength and power Issues with hydration- people may limit fluid intake to manage urinary symptoms Short term memory loss Risk of hyperthermia Side effects of medications

How does PA affect MS ?

Improved physical function, strength and balance, endurance, walking speed. Mobility and cardiorespiratory fitness Reduced fatigue Improved cognitive function

What effect might parkinsonism disease have on PA?

Side effects of medications Cognitive impairment Increased falls risk and impaired balance

What are the benefits of PA in parkinsons disease

Improved motor function, mobility, endurance, reduced gait freezing and walking speed Improved cognitive function Improved quality of life
