“…Well‐established lifestyle management includes diet, increased physical activity, and weight control 24, 25. However, only 10% to 42% of young adults meet the optimal physical activity levels recommended26, 27 and the prevalence of obesity among young adults is persistently increasing not only in Korea28 but also globally 29. Therefore, lifestyle modification should be emphasized in those with high cholesterol levels.…”

BackgroundAlthough high serum cholesterol in young adults is known to be a predictor for cardiovascular events, there is not enough evidence for the association of cholesterol level change with cardiovascular disease (CVD). This study aimed to evaluate whether the change in cholesterol is associated with incidence of CVD among young adults.Methods and ResultsWe examined 2 682 045 young adults (aged 20–39 years) who had undergone 2 consecutive national health check‐ups provided by Korean National Health Insurance Service between 2002 and 2005. Cholesterol levels were classified into low (<180 mg/dL), middle (180–240 mg/dL) and high (≥240 mg/dL). CVD events were defined as ≥2 days hospitalization attributable to CVD for 10 years follow‐up. Increased cholesterol levels were significantly associated with elevated ischemic heart disease risk (adjusted hazard ration [aHR]=1.21; 95% confidence interval [CI]=1.03–1.42 in low‐high group and aHR=1.21; 95% CI=1.15–1.27 in middle‐high group) and cerebrovascular disease (CEVD) risk (aHR=1.24; 95% CI=1.05–1.47 in low‐high group and aHR=1.09; 95% CI=1.02–1.16 in middle‐high group). Decreased cholesterol levels were associated with reduced ischemic heart disease risk (aHR=0.91; 95% CI=0.88–0.95 in middle‐low group, aHR=0.65; 95% CI=0.56–0.75 in high‐low group and aHR=0.68; 95% CI=0.65–0.73 in high‐middle group). Furthermore, lower cerebrovascular disease risk (aHR=0.76; 95% CI=0.62–0.92) was observed in the high‐low group compared with patients with sustained high cholesterol.ConclusionsThe findings of our study indicate that increased cholesterol levels were associated with high CVD risk in young adults. Furthermore, young adults with decreased cholesterol levels had reduced risk for CVD.

“…Moreover, in all the abovequoted studies, different criteria were used to verify the activity of the various levels of intensity. Tucker and Welk [21], for the level of MVPA accepted values of >2020 counts/ min, while Harrisand Owen [17] >2,000 counts/min, Davis and Fox [18] >1,952 counts/min, Colley and Garriguet [19] >1,535 count/min, and Hurtig-Wennlof and Hagstromer [20] > 760 count/min. The inclusion of such low value probably contributed to the high proportion of Swedish seniors meeting the criteria for health-enhancing physical activity.…”

Nawrocka A, Mynarski W, Cholewa J. Adherence to physical activity guidelines and functional fitness of elderly women, using objective measurement. Ann Agric Environ Med. 2017; 24(4): 632-635. doi: 0.5604/12321966.1231388 Abstract Introduction and objective. Physical activity is an important factor in maintaining the health and functional fitness of elderly people. The aim of the study was to determine the number of senior women meeting the physical activity guidelines, and their level of functional fitness in comparison to women who are not sufficiently physically active. Materials and method. The study involved 61 women, aged 60-75. Physical activity was monitored on seven consecutive days of the week, using a triaxial accelerometer ActiGraph GT3X. Results of the assessment of physical activity were verified against the Global Recommendations of Physical Activity for Health. The Senior Fitness Test (Fullerton Test) was used to evaluate functional fitness. Results. In the studied group, 36.1% achieved the recommended level of physical activity. All those examined mainly undertook physical activity of low intensity. Vigorous physical activity during the week was noted in only 6 seniors. Women who met the recommendations of physical activity achieved significantly better results in test trials, e.g. Chair Stands, Up and Go, Six Minute Step Test. Conclusions. Adherence to physical activity guidelines was associated with better functional fitness of older women. However, less than half of the examined seniors met the Global Recommendations on Physical Activity for Health.

“…Despite clear recommendations on the minimal amount of physical activity for achieving health benefits and reducing risk of chronic disease (Garber et al 2011), the majority of people in the developed world remain largely sedentary (Tucker et al 2011;Colley et al 2011;Allender et al 2008). As 'lack of time' has been identified as one of the main barriers to becoming and remaining physically active (Korkiakangas et al 2009;Reichert et al 2007), over the past decade research has focused on high-intensity interval training (HIT) as a timeefficient alternative to aerobic exercise .…”

Physiological and molecular responses to REHIT 2 ABSTRACT Purpose:We have previously shown that six weeks of reduced-exertion high-intensity interval training (REHIT) improves VȮ2max in sedentary men and women, and insulin sensitivity in men. Here we present two studies examining the acute physiological and molecular responses to REHIT. Methods:In Study 1, five men and six women (age: 26±7 y, BMI: 23±3 kg•m -2 , VȮ2max: 51±11 ml•kg -1 •min -1 ) performed a single 10-min REHIT cycling session (60 W and two 20-s 'allout' sprints), with vastus lateralis biopsies taken before and 0, 30 and 180 min post-exercise for analysis of glycogen content, phosphorylation of AMPK, p38 MAPK and ACC, and gene expression of PGC1α and GLUT4. In Study 2, eight men (21±2 y; 25±4 kg•m -2 ; 39±10 ml·kg -1 ·min -1 ) performed three trials (REHIT, 30 min cycling at 50% of VȮ2max, and a resting control condition) in a randomised cross-over design. Expired air, venous blood samples, and subjective measures of appetite and fatigue were collected before and 0, 15, 30 and 90 min post-exercise.Results: Acutely, REHIT was associated with a decrease in muscle glycogen, increased ACC phosphorylation, and activation of PGC1α. When compared to aerobic exercise, changes in VȮ2, RER, plasma volume, and plasma lactate and ghrelin were significantly more pronounced with REHIT, whereas plasma glucose, NEFAs, PYY, and measures of appetite were unaffected. Conclusions:Collectively these data demonstrate that REHIT is associated with a pronounced disturbance of physiological homeostasis and associated activation of signalling pathways, which together may help explain previously observed adaptations once considered exclusive to aerobic exercise.
