PHYSICAL ACTIVITY AND WEIGHT LOSS Flashcards
HOW DOES WHO DEFINE PHYSICAL ACTIVITY?
ANY BODILY MOVEMENT PRODUCED BY SKELETAL MUSCLES THAT REQUIRES ENERGY EXPENDITURE. IT REFERS TO ALL MOVEMENT INCLUDING DURING LEISURE TIME, FOR TRANSPORT OR AS A PART OF PERSON’S WORK
HOW IS EXERCISE DEFINED?
PHYSICAL ACTIVITY THAT IS PLANNED, STRUCTURED AND REPETITIVE FRO THE PURPOSE OF CONDITIONING ANY PART OF THE BODY. IT IS USED TO IMPROVE HEALTH, MAINTAIN FITNESS AND IS IMPORTANT AS A MEANS OF PHYSICAL REHABILITATION. NOT ALL PHYSICAL ACTIVITY IS EXERCISE AND THE TERMS AREN’T ENTIRELY INTERCHANGEABLE. EXERCISE OFTEN HAS MORE NEGATIVE CONNOTATIONS THAN PHYSICAL ACTIVITY.
BMI IS USED TO ASSESS DISORDERS OF WEIGHT OF ADULTS, BUT CANNOT BE USED ON ITS OWN IN CHILDREN. WHY? HOW ARE CHILDREN’S DISORDERS OF WEIGHT ASSESSED INSTEAD?
- BMI ALONE CANNOT BE USED BECAUSE CHILDREN ARE CONSTANTLY GROWING
- BMI IS CALCULATED BUT ADJUSTED FOR AGE/SEX TO COMPARE TO AN AVERAGE FOUND ON A NATIONAL SCALE (CALLED ZBMI)
WHAT IS BMI ADJUSTED FOR CHILDREN CALLED?
ZBMI
1 IN HOW MANY CHILDREN AGED 10-11 ARE OBESE IN THE UK?
1/5
1 IN HOW MANY ADULTS IN THE UK IS OBESE?
1/4
IF SOMEONE HAS A BMI OF 25-34.9, WHICH ADDITIONAL MEASUREMENT COULD BE USED TO HELP DETERMINE EXCESS FAT?
MEASUREMENT OF WAIST SIZE;
MEN: 94CM +
WOMEN: 80CM +
BMI LIMITATIONS:
- MUSCULAR PEOPLE COULD APPEAR OBESE
- NO CONSIDERATION OF AGE, SEX OR ETHNICITY
HOW MANY MINS OF MODERATE INTENSITY EXERCISE PER WEEK ARE RECOMMENDED FOR ADULTS?
150MIN
WHEN ASKING FOR LEVELS OF PHYSICAL ACTIVITY, ARE CATEGORICAL OR OPEN ANSWER MODES MORE USEFUL?
CATEGORICAL
THE FITT PRINCIPLE, MEANINGS:
F, FREQUENCY: HOW OFTEN YOU’RE PHYSICALLY ACTIVE
I, INTENSITY: HOW HARD YOU WORK WHEN YOU’RE PHYSICALLY ACTIVE
T, TIME: HOW LONG YOU’RE PHYSICALLY ACTIVE FOR
T, TYPE; WHAT KIND OF PHYSICAL ACTIVITY YOU CHOOSE
WHAT IS ‘NATIONAL CHILD MEASUREMENT PROGRAMME’ (NCMP)?
- ESTABLISHED IN 2006
- NATIONALLY MANDATED PUBLIC HEALTH PROGRAMME
- PROVIDES DATA FOR CHILD EXCESS WEIGHT INDICATORS IN THE PUBLIC HEALTH FRAMEWORK
- PART OF GOVERNMENT’S APPROACH TO TACKLING CHILD OBESITY
- INVOLVES 4-5 Y.O. AND 10-11 YEAR OLDS AT STATE-FUNDED SCHOOLS, INCLUDING ACADEMIES IN ENGLAND
- HEIGHT AND WEIGHT MEASURED BY SCHOOL NURSE EMPLOYED BY LOCAL AUTHORITY
- MORE THAN 1 MIL CHILDREN MEASURED ANNUALY
IN THE NATIONAL CHILD MEASUREMENT PROGRAMME (NCMP) WHAT IS MEASURED?
HEIGHT AND WEIGHT
WHICH SEX GENERALLY HAS FASTER METABOLISM AND WHY?
MEN, BECAUSE THEY HAVE (PROPORTIONALLY) MORE MUSCLE MASS, HEAVIER BONES AND LESS BODY FAT. MUSCLE CELLS GENERALLY REQUIRE MORE ENERGY TO BE MAINTAINED THAN FAT CELLS SO PEOPLE WITH MORE MUSCLE THAN FAT TEND TO HAVE FASTER METABOLISM
HOW IS ENERGY COMPENSATION EXPLAINED?
- A LONG TERM INCREASE IN ACTIVITY DOES NOT DIRECTLY TRANSLATE TO AN INCREASE IN TOTAL ENERGY EXPENDITURE (TEE) BECAUSE OTHER COMPONENTS OF TEE MAY DECREASE IN RESPONSE
