“…The magnitude of improvement is similar to that reported by Niederseer et al [25] and Lira et al [39] who both report ~7% improvements in relative V O in cohorts of older adults following 12 weeks of alpine skiing and moderate treadmill running respectively. This increase, although modest, would still represent a significant reduction in mortality risk [30] as it approximates 0.6 METs in older males [40].…”

“…Similarly, the ~2% decrease in body fat percentage observed in SED is in line with a previous investigation [25] which reported a of 2.3% reduction following 12 weeks of alpine skiing. SED body mass decreased 1.3% in the present investigation whereas previous investigations have reported a 1.6% decrease following 18 months of combined aerobic and resistance training [41] and no change following 12 weeks of alpine skiing and moderate treadmill running [25,39]. The relatively high body mass loss compared to the previous longer duration study may be attributed to the incorporation of resistance exercise into their exercise training [41], known to cause muscular hypertrophy and therefore attenuate total body mass losses [42].…”

AbstractIntroduction: Advancing age is associated with a gradual decline in circulating androgens and the putative role of exercise training on systemic androgens remain to be adequately defined. Results: Analysis of variance (ANOVA) revealed a lack of significant change in any parameter amongst LE whilst SED experienced a significant exercise-induced improvement in cardiorespiratory fitness, and total testosterone (all p<0.05). Concurrent increases in sex hormone-binding globulin (SHBG; p<0.05) resulted in a lack of change to either bioavailable or calculated free testosterone (p>0.05) amongst SED. MethodsConclusions: Although resting levels of systemic total testosterone increased in response to six weeks of exercise training, increases in SHBG negated any potential relationship between calculated-free or bioavailable testosterone. These findings indicate that increases in bioavailable testosterone fraction are not required for cardiorespiratory fitness improvements in aging men.

“…Regular cardiovascular exercise is shown to improve sleep patterns in aging individuals, and may contribute to overall sleep improvements in caregivers as well. 54 Future research might consider the mediating and moderating relationships of insufficient sleep, physical distress, CHD, and obesity as seen in caregivers of persons with SCI.…”

Context/objective: To compare outcomes among caregivers of adults with spinal cord injuries (SCIs) to caregivers of adults with other neurological conditions, and determine if caregiving for SCI is associated with poor health status and chronic conditions. Design: Secondary data analysis of 2009/2010 Behavioral Risk Factor Surveillance System survey. Participants: Informal caregivers of adults with neurological conditions. Outcome measures: Sociodemographics, caregiving factors (e.g. role, emotional support, life satisfaction), lifestyle behaviors, chronic conditions, and health status. Results: Demographics and lifestyle behaviors did not differ in caregivers of adults with SCI vs. caregivers of adults with other neurological conditions (except younger age of SCI caregivers). Greater proportions of caregivers of adults with SCI had coronary heart disease (CHD) (12% vs. 6%, P = 0.06) and were obese (43% vs. 28%, P = 0.03). Frequent physical distress was reported by 20% of caregivers of persons with SCI (vs. 12% of other caregivers, P = 0.09), but mental health did not differ between caregiver groups. A greater proportion of caregivers of adults with SCI experienced insufficient sleep (47% vs. 30%, P = 0.008) and more days without enough sleep (13 vs. 9 days, P = 0.008). Odds of being younger, caregiver of a spouse, having CHD, and being obese were associated with being a caregiver of an adult with SCI. Conclusion: Caregivers of adults with SCI report similar mental health status, but more poor sleep, and have increased odds of CHD and obesity. Interventions to address physical distress, improve sleep, and address CHD and obesity are needed in this cohort.

“…Furthermore, physical activity has been shown to influence sleep characteristics; a 6 month moderate aerobic training protocol increased the percentage SWS and decreased percentage REM sleep. 60 Taken together, this implies a vice versa effect between EB and the amount of SWS and REM sleep, which appears as a vicious cycle differencing between subjects. A recent study by Mokhlesi et al 61 shows that overweight and obese subjects have less SWS compared with lean subjects, however, two smaller studies in obese subjects did not observe altered sleep characteristics.…”

Distinct associations between energy balance and the sleep characteristics slow wave sleep and rapid eye movement sleep

Distinct associations between energy balance and the sleep characteristics slow wave sleep and rapid eye movement sleep F Rutters, HK Gonnissen, R Hursel, SG Lemmens, EA Martens and MS Westerterp-Plantenga Context: Epidemiologically, an inverse relationship between body mass index (BMI) and sleep duration is observed. Intra-individual variance in the amount of slow wave sleep (SWS) or rapid eye movement (REM) sleep has been related to variance of metabolic and endocrine parameters, which are risk factors for the disturbance of energy balance (EB). Objective: To investigate inter-individual relationships between EB (EB ¼ |energy intake --energy expenditure|, MJ/24 h), SWS or REM sleep, and relevant parameters in normal-weight men during two 48 h stays in the controlled environment of a respiration chamber. Subjects and methods: A total of 16 men (age 23 ± 3.7 years, BMI 23.9 ± 1.9 kg m À2 ) stayed in the respiration chamber twice for 48 h to assure EB. Electroencephalography was used to monitor sleep (2330 --0730 hrs). Hunger and fullness were scored by visual analog scales; mood was determined by State Trait Anxiety Index-state and food reward by liking and wanting. Baseline blood and salivary samples were collected before breakfast. Subjects were fed in EB, except for the last dinner, when energy intake was ad libitum. Results: The subjects slept on average 441.8±49 min per night, and showed high within-subject reliability for the amount of SWS and REM sleep. Linear regression analyses showed that EB was inversely related to the amount of SWS (r ¼ À0.43, Po0.03), and positively related to the amount of REM sleep (r ¼ 0.40, Po0.05). Relevant parameters such as hunger, reward, stress and orexigenic hormone concentrations were related to overeating, as well as to the amount of SWS and REM sleep, however, after inclusion of these parameters in a multiple regression, the amount of SWS and REM sleep did not add to the explained variance of EB, which suggests that due to their individual associations, these EB parameters are mediator variables. Conclusion: A positive EB due to overeating, was explained by a smaller amount of SWS and higher amount of REM sleep, mediated by hunger, fullness, State Trait Anxiety Index-state scores, glucose/insulin ratio, and ghrelin and cortisol concentrations.
