Abstract
Background. Although muscle strength and mass are highly correlated, the relationship between direct measures of low muscle mass (sarcopenia) and strength in association with mortality has not been examined. Methods. Total mortality rates were examined in the Health, Aging and Body Composition (Health ABC) Study in 2292 participants (aged 70–79 years, 51.6% women, and 38.8% black). Knee extension strength was measured with isokinetic dynamometry, grip strength with isometric dynamometry. Thigh muscle area was measured by computed tomography (CT) scan, and leg and arm lean soft tissue mass were determined by dual energy x-ray absorptiometry (DXA). Both strength and muscle size were assessed as in gender-specific Cox proportional hazards models, with age, race, comorbidities, smoking status, level of physical activity, fat area by CT or fat mass by DXA, height, and markers of inflammation, including interleukin-6, C-reactive protein, and tumor necrosis factor-a considered as potential confounders. Results. There were 286 deaths over an average of 4.9 (standard deviation ¼ 0.9) years of follow-up. Both quadriceps and grip strength were strongly related to mortality. For quadriceps strength (per standard deviation of 38 Nm), the crude hazard ratio for men was 1.51 (95% confidence interval, 1.28–1.79) and 1.65 (95% confidence interval, 1.19–2.30) for women. Muscle size, determined by either CT area or DXA regional lean mass, was not strongly related to mortality. In the models of quadriceps strength and mortality, adjustment for muscle area or regional lean mass only slightly attenuated the associations. Further adjustment for other factors also had minimal effect on the association of quadriceps strength with mortality. Associations of grip strength with mortality were similar. Conclusion. Low muscle mass did not explain the strong association of strength with mortality, demonstrating that muscle strength as a marker of muscle quality is more important than quantity in estimating mortality risk. Grip strength provided risk estimates similar to those of quadriceps strength.

Purpose: To quantify the relationship between musculoskeletal fitness and all-cause mortality in the Canadian population. Methods: The sample consisted of 8116 people (3933 men and 4183 women), aged 20-69 yr, who participated in the 1981 Canada Fitness Survey. Measures of musculoskeletal fitness included sit-ups, push-ups, grip strength, and sit-and-reach trunk flexibility. In the 13 yr after the Canada Fitness Survey, there were 238 deaths and a total of 101,685 person-years. Proportional hazar...

Abstract: Health risks in elderly people cannot be evaluated simply in conventional terms of body fatness or fat distribution. Elderly people have less muscle and bone mass, expanded extracellular fluid volumes, and reduced body cell mass compared to younger adults. These nonfat components of body composition play critical roles, influencing cognitive and physical functional status, nutritional and endocrine status, quality of life, and comorbidity in elderly people. Different patterns of “disor...

The elderly population is the fastest growing age group in the United States. This will likely result in more elderly patients presenting for urologic surgery annually. When considering a patient for surgery, age alone should not be a contraindication. The decision on surgery should be individualized for the patient and their problem.

Abstract Preserving or restoring adequate nutritional status is a key factor to delay the onset of chronic diseases and to accelerate recovery from acute illnesses. In particular, consistent and robust data show the loss of muscle mass, that is, sarcopenia, is clinically relevant since it is closely related to increased morbidity and mortality in healthy individuals and patients. Sarcopenia is defined as the age-related loss of muscle mass and function. International study groups have recently p...

Study 1 Purpose. The purpose of this study was to determine whether awareness and utilization of fitness resources and overall physical activity engagement differed depending on residential distance from community-based fitness resources (CBFR). Methods. Four hundred and seventeen older adults (72.9 ± 7.7 years) were randomly recruited from three spatial tiers (≤1, >1 to ≤2, and >2 to 5 miles) surrounding seven senior centers, which housed CBFR. Participants were mailed and returned a health his...

The sphingolipids are a family of membrane lipids with only a structural role, influencing lipid bilayer properties, but they also act as effector molecules with essential roles in many aspects of cell biology. The sphingolipids ceramide, sphingosine and S1P have shown opposite effects: whereas ceramide and sphingosine usually inhibit proliferation and promote apoptotic responses to different stress stimuli, S1P is known to stimulate cell growth, and promote cell survival. Ceramide can be produc...

Due to recent changes in physical activity practices, strength training, or resistance training, has become an area of focus in the research of determining the overall health of an individual. As individuals age, disorders relating to both bone and muscle begin to cause a decline in health and functional activity. Bone disorders, such as osteoporosis and osteopenia, have been linked to muscle disorders like sarcopenia (a loss of skeletal muscle mass). While these disorders do affect males, femal...
