|July 26, 2016
Summary
Masters swimmers aged 70-71 maintained lower body fat and higher aerobic power, comparable to young adults. Regular training may counteract age-related body composition and fitness declines.
Area of Science:
- Gerontology
- Exercise Physiology
- Sports Science
Background:
- Aging is typically associated with increased body fat and decreased aerobic capacity.
- Sedentary lifestyles accelerate these age-related physiological declines.
- Masters athletes represent a unique cohort for studying the long-term effects of lifelong physical activity.
Purpose of the Study:
- To investigate the physiological adaptations in elderly female masters swimmers.
- To compare body composition and aerobic power of older athletes with sedentary peers and younger athletes.
- To determine if regular physical training can mitigate age-associated body fat accumulation and loss of cardiorespiratory fitness.
Main Methods:
- Cross-sectional study comparing two groups of female masters swimmers (70-71 years old) with sedentary females of the same age.
- Inclusion of younger female athletes for comparative analysis.
- Assessment of body fat percentage and maximal oxygen uptake (Vo2 max).
Main Results:
- Masters swimmers exhibited significantly lower percent body fat compared to sedentary women of the same age.
- The body fat levels of the older swimmers were comparable to those of young adult women (19-25 years old).
- Masters swimmers demonstrated Vo2 max values approximately double those of their sedentary counterparts and comparable to younger non-athletes.
Conclusions:
- Lifelong regular physical training, exemplified by masters swimmers, can significantly delay or prevent excess fat accumulation during aging.
- Consistent exercise may effectively offset the age-related decline in aerobic power (Vo2 max).
- These findings highlight the potent role of sustained physical activity in maintaining a healthy body composition and high cardiorespiratory fitness throughout the lifespan.

Body Water Content and Fluid Compartments

Life's biochemical processes occur within aqueous solutions. Solutes are substances that are dissolved within these solutions. The human body contains a variety of solutes, which can differ across various body parts. These can encompass proteins—such as those responsible for clotting and carbohydrate transport—as well as electrolytes. In medicine, an electrolyte is often described as a mineral ion derived from a salt possessing an electric charge. Examples include sodium ions...

Specialized Characteristics of Cardiac Muscles
4.7K
The primary role of cardiac muscles is to propel blood throughout the cardiovascular system. The cardiac muscle cells, or cardiomyocytes, exhibit specialized characteristics that allow them to perform this function.
Cardiac muscle cells are smaller than skeletal muscles, averaging 10–20 mm in diameter and 50–100 mm in length. However, they have large energy demands for continuous contraction and relaxation. This energy is almost exclusively derived from aerobic metabolism of energy...

Exercise and Cardiac Output
2.4K
Regular physical activity is essential for maintaining cardiovascular health, with aerobic exercises being particularly effective. According to the American Heart Association, 150 minutes of moderate to intense aerobic exercise per week is recommended for a healthy heart. Aerobic activities may include brisk walking, running, bicycling, cross-country skiing, and swimming, ideally performed three to five times per week.

Typical Model Studies
674
Fluid mechanics model studies often utilize scaled-down systems to predict fluid behavior in full-scale environments, such as river flows, dam spillways, and structures interacting with open surfaces. Maintaining Froude number similarity in river models is crucial, as it replicates surface flow features like wave patterns and velocities.

Mate Choice

Mate choice—the decision about whom to mate with—is a type of natural selection, since animals must reproduce to pass down their genes. Mate choice is also called intersexual selection because the behavior occurs between the sexes.

Adaptations that Reduce Water Loss
28.5K
Though evaporation from plant leaves drives transpiration, it also results in loss of water. Because water is critical for photosynthetic reactions and other cellular processes, evolutionary pressures on plants in different environments have driven the acquisition of adaptations that reduce water loss.
