Association Between Aerobic and Muscle-Strengthening Activities and Health-Related Quality of Life in Patients with Neck Pain: The National Health and Nutrition Examination Survey 2001-2004.

Different types of activities have independent and additive benefits for adult health. This study intended to assess the association between aerobic activity and muscle-strengthening activities and health-related quality of life (HRQoL) and physical and mental health in patients with neck pain. This cross-sectional study included data on patients with neck pain from the National Health and Nutrition Examination Survey (NHANES) dataset between 2001 and 2004. Weighted logistic regression analyses were applied to estimate the odds ratio (OR) and 95% confidence interval (CI) for the associations between aerobic activity, muscle-strengthening activities, and their combination, and HRQoL, physically unhealthy days (≥14 days/month), and mentally unhealthy days (≥14 days/month). Subgroup analyses were performed according to age, gender, and screen time. A total of 794 patients with neck pain were included, of whom 504 had good HRQoL and 290 had poor HRQoL. Aerobic activity (OR=0.35, 95% CI: 0.21-0.57) and muscle-strengthening activities (OR=0.50, 95% CI: 0.26-0.98) were associated with good HRQoL in patients with neck pain, but only aerobic activity (OR=0.42, 95% CI: 0.28-0.63) was linked to shorter physical unhealthy days. No associations were found between aerobic activity, muscle-strengthening activities, and mentally unhealthy days (P>0.05). The trends for the combined result of aerobic activity and muscle-strengthening activities on HRQoL, physically unhealthy days, and mentally unhealthy days were significant (Ptrend <0.001). Subgroup analyses found that the combined result of aerobic and muscle-strengthening activities was only more significant on HRQoL in patients aged <60 years or ≥60 years, males or females, and patients with screen time <3 hours or ≥3 hours (Ptrend <0.05). Aerobic and muscle-strengthening activities were associated with good prognosis in patients with neck pain, but the effect of aerobic activity may be more pronounced.

The Effect of Aerobic Activity on Changes in Cystatin C and Homocysteine Levels as Cardiovascular Risk Factors

Background and Objectives Chronic inflammation is associated with the development of various diseases, including atherosclerosis and diabetes. The aim of this study was to investigate the effect of longterm selected aerobic exercises on changes in cystatin C and homocysteine in inactive and overweight middle-aged women. Subjects and Methods Thirty non-athlete middle-aged women (mean age: 46.06±6.97 years, weight: 71.82±9.11 kg, height: 156.9±5.24 cm, and body mass index: 29.2±4.11kg/m2) voluntarily participated in this project and were randomly divided into the experimental and control groups The experimental group performed selected aerobic exercises (65-75% of maximum heart rate) for eight weeks. Blood samples were taken before and 24 hours after the completion of the research protocol to measure the levels of cystatin C and homocysteine. Analysis of covariance was used for intergroup comparisons and paired t-test was used for intergroup comparisons. Results The results showed that there was no significant difference between the experimental and control groups in cystatin C (P=0.09) and homocysteine (P=0.07) after eight weeks of selected aerobic exercises. A significant decrease was observed in weight (P=0.001) and body mass index (P=0.002) in the experimental group compared to the control group. Conclusion Overall, the results of the present study showed that although the eight-week activity program improved the body composition of overweight middle-aged women, longer periods of aerobic exercise are required to examine clearer biochemical results.

Aerobic Training Effect on Blood S-Klotho Levels in Coronary Artery Disease Patients

Rationale: Aerobic exercise and Klotho gene expression reduce the risk of cardiovascular events in patients with prior coronary artery disease (CAD) thus, aerobic exercise may create a decreased risk of mortality. Objective: The purpose of the present study was to compare the association between s-klotho serum levels and IGF-1 levels in 3 groups: 60 untrained coronary artery disease patients (CAD) age 52.6 ± 2 years, 60 active participants with CAD in supervised aerobic programs for at least 12 months (4-5 times•wk-1) age 53.0 ± 2 years, and 40 untrained healthy males, age 53.6 ± 1.5 years to assess association of aerobic training and s-klotho activity. Methods and results: Blood samples were drawn from a forearm vein after overnight fasting, s-Klotho levels in the serum were analyzed using an α-klotho Enzyme Linked Immunosorbent Assay ELISA kit, while, IGF-1 was measured by a chemiluminescent immunometric method. Significant (p>0.05) differences were noted between the aerobically trained CAD patients and both untrained groups: CAD patients and healthy subjects with regard to s- Klotho (491 ± 66, 386 ± 70 and 418 ± 81 pg•mL-1 respectively), IGF-1 (82 ± 12, 106 ± 21 and 98 ± 14 nmol•L-1 respectively) and maximal oxygen uptake (42.1 ± 4.5, 31.9 ± 3.9 and 35.8 ± 2.9 mL•kg-1•min-1 respectively). Conclusions: S-Klotho and aerobic exercise training are factors that may promote upgrading capacities of the CAD patients. Inflection of Klotho expression through aerobic training represents a relationship that may contribute to the explanation of the effects of aerobic activity on CAD patients. In addition, findings suggest that atenolol treatment does not influence s-Klotho and IGF-1 levels in CAD patients treated with atenolol.

Effects of age and lifetime flight behavior on senescence and reproduction in Drosophila (880.2)

The effects of aerobic activity on physiology and senescence may be profound in variably active species such as flying insects, which attain among the highest metabolic rates ever measured. Flight capacity in insects decreases with age, although limiting flight behavior extends lifespan, slows the age‐related loss of antioxidant capacity and accumulation of oxidative damage, and potentially allows for greater energy investment in non‐locomotor traits such as reproduction. We tested the effects of age and lifetime flight behavior on flight capacity, longevity and reproduction in Drosophila. Specifically, 5 day‐old adult flies were separated into three life‐long treatments: (A) those not allowed to fly (no flight or NF), (B) those allowed ‐ but not forced ‐ to fly (voluntary flight or VF), and (C) those mechanically stimulated to fly (induced flight or IF). Longevity was in the order NF&gt;VF&gt;IF, although the ability to fly and attain high metabolic rates persisted the longest in VF flies. Age‐specific fecundity did not vary among the groups, although NF flies had the greatest lifetime fecundity due to their longer lifespans. These results indicate that aerobic locomotor behavior can accelerate physiological senescence and trade‐off against other traits.Grant Funding Source: National Science Foundation IOS‐0725030

The Effects of Aerobic Activity on Brain Structure

Aerobic activity is a powerful stimulus for improving mental health and for generating structural changes in the brain. We review the literature documenting these structural changes and explore exactly where in the brain these changes occur as well as the underlying substrates of the changes including neural, glial, and vasculature components. Aerobic activity has been shown to produce different types of changes in the brain. The presence of novel experiences or learning is an especially important component in how these changes are manifest. We also discuss the distinct time courses of structural brain changes with both aerobic activity and learning as well as how these effects might differ in diseased and elderly groups.
