Physical Activity and Health Flashcards
Current UK guidelines - infants
Not mobile - at least 30 minutes tummy time spread throughout the day
Toddlers- at least 180 mins per day in variety of physical activities, any intensity
Pre schoolers “ “. Should include t least 60 mins mod-big
Children - moderate to vigorous activity for at least 60mins a day
Current UK guidelines - adults (19-64)
Physically activity every day, muscle strengthening activities on at least 2 days a week, 150 mins moderate activity each week or 75 mins vigorous
65 years plus - aimed at improving/maintain muscle strength, balance and flexibility on at least 2 days
Key changes in guidelines
No minimum amount of PA required to achieve some health benefits
Benefits of HIIT acknowledges
Under 5s: 3 development stages
Define sedentary behaviour
Refers to any waking activity characterised by an energy expenditure less/equal to 1.5 METS and a sitting/reclining position
What activity is defined by 1 MET
Resting
Define muscular strength
Maximal force capability
Muscular endurance definition
Ability to continue muscular contraction over time
Define cardiorespiratory endurance
Ability to perform large muscle, whole body exercise at moderate to high intensities for extended periods of time
Define validity
Extent to which a measurement instrument assesses the true exposure of interest
What are cross sectional and what are the advantages and disadvantages
Data from a population at one specific point in time
Quick, easy
Can’t analyse behaviour over a period of time
What is a cohort study and what are the advantages and disadvantages
Type of longitudinal study that samples a cohort (group of people who share a characteristic) performing a cross section at interval through time
Can be retrospective or prospective
expensive, attrition, time consuming
What is an intervention study
Investiogator assigns he exposure
Subjects followed prospectively to compare
What are randomised control studies
Participants randomly assigned to one of 2 groups - experimental or controls
Groups followed prospectively to assess effectiveness of intervention compared to standard/placebo treatments
Eliminates bais
How can you assess muscular strength
Dynamometers (grip)
Tensiometers - adjust to test multiple joint angles
Repetition maximum
How can you test endurance
Field tests
