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...

The influence of socioeconomic status on health-related fitness is not clear. To examine the influence of socioeconomic status on health-related fitness in adolescents. A total of 3,259 adolescents (15.0 +/- 1.3 y) from the Healthy Lifestyle in Europe by Nutrition in Adolescence Cross-Sectional Study (HELENA-CSS) participated in the study. Socioeco...

We studied which physiological and kinanthropometric characteristics determine climbing performance in 16 high-level sports climbers aged 29.9 +/- 4.9 years. Body composition parameters were measured with dual energy X-ray absorptiometry scanner. We also measured kinanthropometric and physical fitness parameters. The sex-specific 75th percentile va...

The use of vibrating platforms as a training method is widely used in sport training. The vibration stimulates the neurological structures of the body, therefore, both muscle receptors and cortical and medulla structures are activated. The vibration stimulus is known to induce force and power gains, as well as cardiorespiratory adaptations. Endocri...

Objective: To analyse performance, anthropometric and muscle strength characteristics in elite rock climbers. Materials and methods: Years of climbing experience, days/week of climbing, hardest outdoor "onsight", hardest outdoor "red point", body weight, skinfold thicknesses and handgrip strength were measured in 23 Spanish elite climbers (11 men a...

Introducción y objetivos. En diversos estudios se ha mostrado la relación entre el nivel de forma física durante la infancia-adolescencia y el riesgo cardiovascular en la edad adulta. Dado que no se dispone de datos relativos al nivel de condición física de los adolescentes españoles, los objetivos de este estudio son: a) determinar el nivel de con...
Article
Several recent important studies have clearly shown that a low physical fitness represents a potent risk factor and even a predictor of both cardiovascular and all-causes morbidity and mortality. As a consequence, physical fitness assessment should be performed at the clinical level since, when properly assessed, it is a highly valuable health and...

Dehydration is one of the main problems associated to endurance sports. In order to avoid the negative effects of dehydration athletes tend to drink well above their current needs. The negative effect of drinking too much fluid is hyponatremia. Hyponatremia is defined as a plasma sodium concentration lower than 135 mmol/L. Hyponatremia is the first...

Background. Prevalence of childhood obesity and overweight is increasing in developed countries. Interventions of different society institutions are required, being particularly relevant educational institutions. Aim. To assess the effects of a nutritional and physical activity program on total and central body fat in school adolescents. Method. 46...

... 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. ...
... La mayoría de estudios encontrados en la bibliografía arrojan datos de porcentaje de grasa corporal para hombres entre el 6,0 y el 9,8%, estando en concordancia con los deportistas de este estudio (Mermier et al., 2000;Watts et al., 1993;Egocheaga et al.;España Romero et al., 2006, 2009a (Tabla V). Valores más altos son los aportados por Grant et al. en escaladores con un de 14,0% de grasa y un gran peso corporal (74 kg) y en escaladores españoles con un 13,5%, pero valorados mediante DEXA. ...
... En el problema de enfermedades crónicas, alergias e intolerancias alimentarias, se refuerza la importancia de la autonomía y adaptación del enfermo a su entorno, reflejándose una idea de salud dinámica y ecológica. En el problema de «mala práctica de la actividad física y deportiva», reaparece de nuevo la autoestima, así como la importancia de integrar la actividad física y la alimentación para mejorar la salud, en línea con otros autores (Ortega et al., 2004;Rye et al., 2008). ...
... In previous research, children with higher SES were reported to perform better in physical activities and fine motor skills compared to children from lower SES backgrounds because parents at higher SES levels tend to acknowledge their importance (Aiman et al., 2016;Hong, 2007). Within China, it is commonly understood that families with higher SES have the financial capability to provide learning opportunities and materials that enhance their children's development, especially in motor skill development (Jiang, 2011;Jiménez Pavón et al., 2010;Joens-Matre et al., 2008). The lack of association between these variables might have to do with the changing lifestyles of Chinese families due to increasing urbanization that results in reduced spaces and opportunities for outdoor play. ...
... 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. ...
... Physical fitness covers all the physical qualities of a person and could be an integrated part of all the functions and structures involved in the performance of physical exertion [7]. ...
... 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). ...
... In addition, poor physical fitness could have a greater influence than other well-established factors, such as dyslipidemia, hypertension, or obesity [21]. Conversely, a high level of physical fitness is associated with a reduction in CVD risk factors [21,22], and is potentially a useful predictor of CVD risk factors and overall health [23]. The investigation of these factors could be relevant for the diagnosis and prevention of many diseases in adults. ...
... According to the study of Philippe et al. (2012), there are no differences between male and female elite and high-level performance climbers (21-32 years old) in terms of forearm and finger flexor muscle fatigue. Furthermore, differences among male and female elite climbers (24-37 years old) were not found in general fitness tests (sit & reach relative handgrip strength) (Espana-Romero et al., 2009). However, Wu et al. (2011) show the results from Chinese elite climbers (23-38 years old), where gender differences in handgrip strength are found (males have better results). ...
... Physical fitness is an integrated measure of all the functions and structures involved in performing physical activity [1]. Nowadays, physical fitness is one surrogate marker of overall adult health (19-64 years), especially cardiorespiratory fitness and muscular strength. ...
