_______ or _______ in many physical functions
occur very gradually through the 40s and 50s
Changes ; declines
Define middle adulthood
the developmental
period for adults ranging 40 to 45 years of
age to 60 to 65 years of age.
A full evaluation of age requires consideration
of:
- Chronological age
- Biological age
- Psychological age
- Sociocultural age
- Perceived age
Exercise capability
declines
1% per
year beginning
between 35 and 40
Late midlife (55 to 65) is likely to be characterized by:
- Death of a parent.
- The last child leaving the parental home.
- Becoming a grandparent.
- Preparation for and actual retirement.
Visible signs of physical changes:
• Skin wrinkles and sags. • Age spots appear. • Hair thins and grays. • Nails thicken and become more brittle. • Teeth yellow.
Maximum oxygen
uptake (VO2 max):
a measure of the body’s ability to take in and transport oxygen to various body organs
As adults become older, their age _____ is
younger than their ________age.
identity ; chronological
Lung tissue becomes
___ _____ around
age 55, decreasing
lung capacity.
Less elastic
Sarcopenia:
an age-related loss of muscle mass
and strength.
\_\_\_\_\_\_-\_\_\_\_\_\_\_ improves with practice at almost every age
weight-training
Strength is at its peak in the \_\_\_ and \_\_\_ and then \_\_\_\_\_\_\_\_\_
20s; 30s
declines
How much sleep is necessary for optimal
performance the next day?
8 hours or more
Ineffective immune system
functioning is linked to ___ _____
Less sleep
White matter volume ________ until middle adulthood and then _________
Increases; decreases
Crests
Grey matter volume ________ from childhood and then ___________ at the end of middle adulthood
declines; levels off
________________ increases at a regular rate across the lifespan
Cerebrospinal fluid (CSF)
The general rule of
brain maturation is:
the areas of the brain that develop last are the ones that begin to decline first; • Namely areas located within the frontal and parietal lobes
The brains of alcoholics differ in _________ and ________.
Electrical activity; grey matter volume
Adults with serious mental illnesses, such as
depression and schizophrenia, have brains with
distinct brain structure variations. Did these brain variations happen before or after the onset of the mental illness?
It is not yet known if the brain differences happen before or after the onset of the difficulties
Presbyopia:
Normal loss of visual acuity with aging, especially the ability to focus the eyes on near objects (ie, things get blurry) • The ability to focus on near objects deteriorates rapidly in the 40s and early 50s
At what age can hearing start to decline?
Forty
decline accelerates after age 55
Which type of sounds are typically lost first?
High pitched sounds
Normal loss of hearing with aging,
especially of high-frequency or very low-frequency tones
Presbycusis
Climacteric
the adult period during which
reproductive capacity declines or is lost
Climacteric in men
extremely gradual, with a
slow loss of reproductive capacity
• High degree of individual variation; men have been
reported to father children as late as age 90
• Probably due to a slow decrease in testosterone
levels
Effects of decreased testosterone levels
- Gradual muscle loss (and strength)
- Increased risk of heart disease
- Increased sexual dysfunction
Erectile dysfunction;
difficulty attaining or maintaining
erection occurs in approx. 50% of men aged 40-70 years
Which are the only five mammals that experience menopause?
- Humans
- Orcas
- Pilot whales
- belugas
- narwhals
Menopause
The cessation of monthly menstrual
cycles in middle-aged women
Due to a decline in key sex hormones (Estrogen
and progesterone)
