Weight Loss: Physical Activity

Question 1

Additive TEE:

Answer 1

• TEE continues to rise linearly over time

- non-PA metabolic activity remains the same over time

Question 2

Constrained TEE:

Answer 2

• TEE levels out over time

- non-PA metabolic activity decreases over time

Question 3

The most likely explanation for a return to energy balance is….

Answer 3

a compensatory increase in energy intake

Question 4

How does resistance training effect weight loss?

Answer 4

• unlikely to result in clinically significant weight loss alone
• may assist with wait loss or maintenance when combined with aerobic exercises
• improve muscular strength, resulting in a greater free-living PA
• 2-3 times per week for major muscle groups

Question 5

Health benefits of PA and exercise:

Answer 5

• CV system
• metabolic system
• mood
• musculoskeletal system
• sleep
• focus

Question 6

Health benefits of PA and exercise in obesity:

Answer 6

• dec. risk of CVD
• dec. risk of diabetes mellitus
• inc. cardiometabolic risk factors

Question 7

Mistakes when training individuals with obesity:

Answer 7

• increased risk for musculoskeletal injuries: perform low-impact exercises of short duration
• watch the exercise dose to prevent fatigue: progressive overload
• supervision of training
• misconception of local fat loss
• misconception of sweating will lead to weight loss: dehydration is harmful

Question 8

Initial assessment for obese should include:

Answer 8

1. individual risk profile
2. medical evaluation
3. fitness assessment
4. individual exercise tolerance

Question 9

Barriers to PA in obesity:

Answer 9

• orthopedic disorders (evaluation of the MS system)
• pulmonary disorders (evaluation of respiratory function)
• mental/psychological disorders

Question 10

Reasons for weight regain after loss:

Answer 10

• changes in appetite hormones (inc. orexigenic and dec. anorexigenic hormones)
• dec. adherence with diets
• dec. resting metabolic rate

Question 11

ACSM recommends _____ min. of moderate PA per week to maintain body weight after weight loss.

Answer 11

200-300 min.

Question 12

Constrained model: the effects of ….. diminish with time

Answer 12

increase PA on TEE

Question 13

Compensatory increase in ____ ____.

Answer 13

energy intake

Question 14

Meta-analyses suggest no clinically significant effects of _____ exercise on whole-body fat mass, independently of exercise ____ and _____.

Answer 14

• aerobic
• volume
• intensity

Question 15

_____ ______ may contribute to the lack of exercise effects at a group level.

Answer 15

individual variability

Question 16

Evidence indicates that ____ exercise may contribute to small reductions in _____ obesity, but the clinical significance remains unclear.

Answer 16

• aerobic

- abdominal

Question 17

____ combined with ___ ____ results in greater weight loss.

Answer 17

• exercise

- calorie restriction

Question 18

____ training alone is unlikely to result in clinically significant weight loss.

Answer 18

resistance
