[Changes in abdominal muscle strength with respect to aging]

Area of Science:

• Gerontology
• Human Physiology
• Musculoskeletal Health

Background:

• Muscle strength is known to decrease with advancing age in adulthood.
• Understanding age-related changes in specific muscle groups is crucial for maintaining health and function.

Purpose of the Study:

• To investigate the effects of aging on abdominal muscle strength.
• To identify the age at which significant declines in abdominal muscle strength occur.
• To explore correlations between abdominal muscle strength, age, and other physical parameters.

Main Methods:

• Measured abdominal muscle strength, height, body weight, and grip strength in 144 healthy adults aged 20-88.
• Utilized a grip dynamometer to assess abdominal muscle strength.
• Analyzed data for correlations between age, abdominal muscle strength, grip strength, and height.

Main Results:

• Abdominal muscle strength showed a gradual decrease with age, with a rapid decline observed in males from the fifth decade and females from the seventh decade onwards.
• Significant negative correlations were found between abdominal muscle strength and age in males (r = -0.64).
• Strong correlations were observed between abdominal muscle strength and grip strength across both sexes, and between age and grip strength/height.

Conclusions:

• Aging is a primary factor contributing to the decrease in abdominal muscle strength.
• The rate of decline in abdominal muscle strength varies between sexes and is influenced by the generation studied.
• The developed method for measuring abdominal muscle strength is practical for assessing age-related muscular changes.
