Background and Aims This study aims to examine associations of food portion sizes (PS) with markers of insulin resistance (IR) and clustered of metabolic risk score in European adolescents. Methods 495 adolescents (53.5% females) from the HELENA study were included. The association between PS from food groups and HOMA-IR index, VO2 max, and metabo...
Article
Background: We compared differences in physical activity (PA) between pre/mid-pubertal and post-pubertal participants according to gender. Methods: The study included a total of 1842 healthy participants aged 12.5-17.4 years, who participated in the Healthy Lifestyle in Europe by Nutrition in Adolescence (HELENA) study. Participants wore a uniax...

We examined the association of physical activity (PA), cardiovascular fitness (CVF) and fatness with total homocysteine (tHcy) concentrations in European adolescents. The present study comprised 713 European adolescents aged 14.8±1.2 y (females 55.3%) from the multicenter HELENA cross-sectional study. PA was assessed through accelerometry, CVF by t...
Article
Objective: To analyze the association between objectively assessed physical activity (PA) and markers of insulin resistance (IR) in European adolescents and to examine whether the association of objectively assessed PA and markers of IR is modified by cardiorespiratory fitness (CRF). Methods: A cross-sectional study at school setting was conduct...
Article
This study investigated differences in health-related fitness (20-m shuttle run, handgrip, bent arm hang, standing long jump, shuttle run 4 x 10 m and sit and reach tests) in 2474 Spanish adolescents (1196 boys and 1278 girls; age 13-18.5 years) classed as underweight, normal weight, overweight or obese according to body mass index. Body fat and fa...
Article
Physical fitness has been proposed as a major marker of health status at any age. The aim of the present study was to determine the levels of several health-related physical fitness components with respect to chronological and biological age (sexual maturation status) in Spanish adolescents. Physical fitness was measured in a sample of Spanish adol...

We studied 278 adolescents (169 females) aged 13.0–18.5 years to elucidate whether an independent effect of physical fitness and lean mass in the differences between male and female bones can be detected. Lean and fat masses and bone mineral content (BMC) were measured with DXA. Physical fitness was evaluated with six different tests included in th...

In adults, obesity is characterized by a state of chronic low-grade inflammation accompanied by moderately high concentrations of acute phase inflammatory proteins. Recent results regarding C-reactive protein (CRP) point to a similar status in adolescents; however, studies of associations of the serum inflammatory proteins CRP, ceruloplasmin, and c...

... Sex-related patterns of PA might be culturally dependent (Beghin et al., 2019). In this study, sex explained variance in the PA in that men were more likely to exercise regularly compared to women. ...
... If any of these crucial vitamins is unavailable, the level of homocysteine, as an indirect metabolite in methionine metabolism, is growing. Elevated level of homocysteine potentiates cardio-vascular problems [2,7]. Increase in homocysteine concentration in blood plasma is directly connected to damage and disfunction of endothelial cells, leads to decreased concentration of nitric oxide (NO) and affects reduced elasticity of arteries. ...
... Some studies support an inverse association between exercise and CRP, IL-6, and fibrinogen (Fg) in youth, but there are also other studies that state the opposite [160]. Some observational studies conducted on children and adolescents have shown that a low-grade inflammatory state is associated with adiposity in children and adolescents, as has been demonstrated in adults [162][163][164]. Low-grade inflammation is associated with anthropometric measures such as body mass index (BMI) and waist circumference in adolescents, but data on children are sparse [162,163]. ...
... Moreover, serum α-tocopherol of males was lower compared with females. It was in accordance with many studies, and those had shown a greater risk of vitamin E deficiency in men than in women [32]. A recent systematic review showed that low vitamin E was harmful to semen quality [33]. ...
... The regular consumption of antioxidant-rich fruit and vegetables should easily provide these preventative plasma concentrations. In addition, epidemiological studies and prospective case-control studies have yielded evidence that eating more fruit and vegetables reduces the risk of cognitive impairment [18,19]. ...
... metabolism of nutrients, beta-cells dysfunction, and IR via playing an essential role in inflammatory reactions and up-regulating inflammatory markers such as IL-6 and CRP [44,45]. Furthermore, vigorous physical activity has been considered a protective factor in decreasing the risk of IR via improving antioxidant capacity, enhancing anti-inflammatory factors, and desirable change in fatdeposition pattern [46,47], also, previous reports have suggested that a sedentary lifestyle and low level of physical activity is associated with low-grade inflammation, characterized by increased levels of inflammatory indicators such as hs-CRP and IL-6 [48]. ...
... Among the different factors that may influence the CF, from genetic to environmental factors ( Barbieri, 2010), stimulating an active lifestyle represents an important contribution to the development and maintenance of the individual's CF (World Health Organization [WHO], 2010). Evidence with accelerometer measurements shows that moderate and/or vigorous intensity physical activity (MVPA) is positively related to CF, with moderate intensity having a weaker relationship with CF than vigorous intensity (Gutin, Yin, Humphries, & Barbeu, 2005), which is based on the results obtained by Martinez-Gomez et al. (2010). ...
... Higher levels of body fatness may impact the physical fitness in children and adolescents [8][9][10][11][12][13][14][15][16]. Specifically, previous evidence has shown that excessive fat mass or body mass index values have been associated with poor cardiorespiratory fitness [13,14] and worse performance in the coordination and agility tests (the 4 × 10 m shuttle run test) [13,14], jumping tests (standing broad jump) [12][13][14], and motor fitness (the 40 m test) [12]. ...
... These protocols are especially focalized on health-related components (cardiorespiratory endurance, muscular strength, flexibility, and body composition), because they have important positive effects on the human body [7]. Field-testing protocols based on fitness evaluation batteries adopted for children and adolescents, such as the AVENA study [10], the FIT-NESSGRAM [11], the HELENA study [12], and the ASSO project [13] also exist. Furthermore, laboratory test for cardiorespiratory [14,15], muscle strength [16], and flexibility [16] components are valid and widely adopted. ...
