Q

– Requires more exercise (60-90 min) than cardiovascular health (30 min)
– Most weight loss from exercise is not from burning calories or from consuming fewer calories but from the elevation in metabolic rate (rate the body metabolizes calories)

10,000 steps

a day. some ways to step it up are:

A

– Take a brisk walk during your lunch break for about 20 minutes or so, about 2,000 steps.

– Play in a basketball game for 30 minutes, more than 4,300 steps.
– Walk one city block, about 200 steps.
– Walk around the track at a high school. Four laps equal about 2,000 steps.

Order Amish who carry a genetic mutation (FTO
gene) associated with weight gain and obesity

25
Q

High levels of physical activity =

– 3-4 hours of moderately intense exercise

26
Q

relationship
between physical activity and cardiovascular
disease (CVD) for both men and women(also true for stroke)

A

dose-response relationship

27
Q

dose-response relationship

between physical activity and premature death

A

stronger for men then for women

28
Q

Exercise decreases “bad” cholesterol or lowdensity lipoprotein (LDL)
• Exercise increases “good” cholesterol or highdensity lipoprotein (HDL)
• Therefore, the ration of HDL to LDL is more
favorable and risk of CVD is decreased
• Especially true for moderate levels of exercise,
with or without dietary changes
• True for both adults and children

A

cholesterol levels

29
Q

Physical activity can offer protection against
development of Type II diabetes (non-insulindependent) by controlling weight
• May be useful for controlling both Type I (insulindependent) and Type II diabetes

A

Control of Diabetes

30
Q

insulin dependent diabetes

A

type 1 diabetes

31
Q

noninsulin dependent diabetes

A

type2 diabetes

32
Q

• Physical activity may protect against many
cancers
• True for women and men
• Effects mediated by proinflammatory cytokines

A

cancer

33
Q

• Physical activity protects against osteoporosis or the reduction in bone density due to calcium loss
• Moderate exercise increases bone mineral density (BMD)
• Decreases hip fractures in both men and women by 25%
• Physical activity during childhood is especially
important for BMD
• People who were formerly active but who reduce
their activity level (become sedentary) lose some of their protection

A

Prevention of Bone Density Loss

34
Q

study by Burns, demonstrated that more physical fitness was associated with less brain shrinkage (atrophy)

A

Patients with Alzheimer’s who had low levels of
fitness had four times more brain shrinkage than
did patients with high levels of fitness

35
Q

• People who exercise are less likely to be
depressed than are sedentary individuals
• No definitive cause-and-effect
• May have benefits

A

mental health:depression

36
Q
  1. Aerobic exercise is more effective than no treatment
  2. Physical therapy is at least as effective as
    psychotherapy
  3. Aerobic and nonaerobic exercise seem to be equally effective in treating depression
  4. No dose-response relationship exists between aerobic exercise and depression (don’t continue to benefit from higher levels)
  5. No evidence for severe forms of major depression
  6. No evidence that it can prevent relapse into a major depression
A

Effectiveness of physical activity for treatment

of depression

37
Q

General personality characteristic manifested as a more or less constant feeling of dread or uneasiness

trait anxiety

38
Q

– Temporary, affective condition that stems from a specific situation
– Usually accompanied by physiological changes such as increased heart rate and perspiration

A

state anxiety

39
Q

research has focused on ___ activity and ___ activity

A

physical; state

40
Q

Moderate physical activity can reduce state
anxiety
• Highly anxious experience greater decreases
than do moderately anxious
• Does not appear to be a dose-response
relationship

A

mental health:anxiety

41
Q

Why does physical activity help?

A

– Change of pace (relaxation and biofeedback also work)

– May alter brain neurotransmitters (e.g., serotonin) that affect mood

42
Q

– Regular exercise lowers stress and improves quality of life
– little as 10 minutes of moderately strenuous exercise elevate mood
-coping behavior
-ppl who are fit may be less vulnerable to stressrelated illness
-PA moderates proinflammatory cytokines

A

mental health:stress

43
Q

• People who participate in exercise programs feel better about themselves
– Remember: increase self-efficacy by doing behavior
• May not directly affect self-esteem, but may
indirectly affect self-esteem through other
positive benefits

A

selfesteem

44
Q

• Overtraining or “staleness”
– Suffer negative mood, fatigue, and depression
• Exercise dependence
• Injuries

A

hazards of physical activity

45
Q

– Strong emotional attachment to exercise
– Exhibit withdrawal symptoms such as depression&anxiety when prevented from exercising
– exercise even when injured
– Progressive self-absorption
– concentrate on thinness/ body image
– Interferes with daily functioning
– Megarexia

A

Exercise dependence or obligatory exercise

46
Q

• Minor injuries and soreness inevitable with reg exercise
• Irregular exercise more likely to result in injuries / discomfort
• Musculoskeletal injuries are common and
increase with greater frequency and intensity of
exercise
• Skeletal injuries also occur and hazards such as heat, cold, dogs, and drivers exist
• Need to decrease exercise when injured – don’t
work through the pain

A

injuries with hazards of physical activity

• Appropriate warm-up and cool-down exercises

A

Reducing Exercise Injuries

49
Q

Cycling Periods of Activity and

Inactivity

A

• Not only can you lose health benefits gained
from physical activity when you stop but
• With repeated cycles it may actually cause you
to gain weight
– Possibly by increasing the number of fat cells
– Not explained by caloric intake
– Also associated with fatty liver (hepatic steatosis)

50
Q

• Only 48% of adults in the US meet physical
activity requirements for health
• For those who participate in prescribed exercise
regimens the dropout rates are high

A

adherence to physical activity

51
Q

– Lack of time and stress undermine good intentions
– About 50% of people who initiate a voluntary exercise program
are still doing it after 6 months

A

Exercise schedules are usually erratic (determinant of reg exercise)

52
Q

Better exercise adherence predicted by:

A

– Being male, being a nonsmoker, having more education, having
a higher income, being younger
– Less self-consciousness, more social support, more exercise self-efficacy, more positive attitudes about exercise

53
Q
  • Self-motivation leads to 15%-20% adherence rates

* Adding cognitive-behavioral strategies to selfmotivation increases adherence rates to 50%-60%

A

Interventions to Increase Maintenance

54
Q

– Reinforcement, contingency contracts, self-monitoring,

modeling, goal setting, prompts, shaping

A

Cognitive-behavioral strategies

55
Q

Understanding motivation and attitudes aids in
development of a program of activities that are liked and are convenient (active and enjoyable lifestyle)
– Match to stage of change

A

Individualized Exercise Programs

56
Q

Telephone and mail reminders are effective in

____ ____

A

relapse prevention

57
