BACKGROUND Swimming, a sport practiced in hypogravity, has sometimes been associated with decreased bone mass. AIM This systematic review aims to summarize and update present knowledge about the effects of swimming on bone mass, structure and metabolism in order to ascertain the effects of this sport on bone tissue. METHODS A literature search was(More)
The analysis and interpretation of heart rate variability (HRV) during exercise is challenging not only because of the nonstationary nature of exercise, the time-varying mean heart rate, and the fact that respiratory frequency exceeds 0.4 Hz, but there are also other factors, such as the component centered at the pedaling frequency observed in maximal(More)
OBJECTIVES The purpose of this study was to determine the sex-specific physical activity (PA) intensity thresholds that best discriminate between unhealthy/healthy cardiorespiratory fitness (CRF). METHODS Participants included 1,808 adolescents (964 girls), aged 12.5-17.5 years, from the HELENA study. We measured PA by accelerometer and calculated the(More)
One of the aims of Identification and Prevention of Dietary- and Lifestyle-Induced Health Effects in Children and Infants (IDEFICS) validation study is to validate field measures of physical activity (PA) and energy expenditure (EE) in young children. This study compared the validity of uniaxial accelerometry with heart-rate (HR) monitoring vs. triaxial(More)
PURPOSE To describe bone status and analyse bone mass in adolescent cyclists. METHODS Male road cyclists (n = 22) who had been training for a minimum of 2 years and a maximum of 7 years with a volume of 10 h/w, were compared to age-matched controls (n = 22) involved in recreational sports activities. Subjects were divided in 2 groups based on age:(More)
AIMS To evaluate the effect of physical performance and extracurricular organized physical activities (EOPA) in normal- and overweight children. METHODS A random sample of 1,068 schoolchildren (7-12 years old) representative of the region of Aragon (Spain) was selected and divided into normal-, overweight and obese groups based on previously published(More)
BACKGROUND Cycling is considered to be a highly beneficial sport for significantly enhancing cardiovascular fitness in individuals, yet studies show little or no corresponding improvements in bone mass. METHODS A scientific literature search on studies discussing bone mass and bone metabolism in cyclists was performed to collect all relevant published(More)
AIM To determine whether the bone mass of young people with Down syndrome may increase, following a 21-week conditioning training programme including plyometric jumps. METHOD Twenty-eight participants with Down syndrome (13 females, 15 males) aged 10 to 19 years were divided into exercise (DS-E; n=14; eight females, six males mean age 13y 8mo, SD 2y 6mo)(More)
BACKGROUND The elderly EXERNET multi-centre study aims to collect normative anthropometric data for old functionally independent adults living in Spain. PURPOSE To describe the standardization process and reliability of the anthropometric measurements carried out in the pilot study and during the final workshop, examining both intra- and inter-rater(More)
INTRODUCTION Adolescence is an important period of nutritional vulnerability due to the increased dietary requirements. OBJECTIVE To describe the nutritional status of adolescent cyclist and a group of normoactive controls. METHODS The HELENA Dietary Assessment Tool was used to evaluate the nutritional intake of 20 adolescent cyclists and 17 controls.(More)
