Physical and Sensorimotor Changes in Adulthood
Unlike
all prior developmental periods, which were characterized by increases in
strength and agility, changes in physical and sensorimotor abilities throughout
adulthood are largely a story of decline. Many of our physical and sensory
abilities peak in our early to mid-twenties and then gradually deteriorate from
this point forward. There are of course profes-sional athletes who manage to
compete at the highest levels into their forties, and healthier lifestyles have
made it possible for adults to run marathons and water ski into their eighties,
but these individuals are the exceptions rather than the rule (Figure 14.37).
The passing decades still bring undeniable losses in physical and sensorimotor
functioning.
Both
sexes experience physical changes in middle age, including weight gain, loss of
muscle mass, and hair thinning and graying. The age-related declines in
physical and sensory capabilities accelerate in older age, and so, as people
age, they become markedly weaker and slower. There are also significant
declines in sight, smell, and hear-ing (see Figure 14.38). These various
changes in turn cause other problems. For example, the risk of a fatal accident
while driving (per mile driven) increases in later adulthood and jumps markedly
after age 70 (Coughlin, Mohyde, D’Ambrosio, & Gilbert, 2004).
