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)
We examined whether elbow position affects the handgrip strength in adolescents. The criterion-related validity and reliability of the Jamar, DynEx, and TKK dynamometers were also analyzed. A total of 66 adolescents aged 12 to16 years performed the handgrip strength test with the elbow extended and flexed at 90 degrees . The validity and reliability of the(More)
BACKGROUND We aimed to examine whether time spent on different sedentary behaviours is associated with bone mineral content (BMC) in adolescents, after controlling for relevant confounders such as lean mass and objectively measured physical activity (PA), and if so, whether extra-curricular participation in osteogenic sports could have a role in this(More)
The aim of this study was to examine the interrater reliability (trained vs. untrained raters) and criterion-related validity (manual vs. automatic timing) of the 4 × 10-m shuttle run and 30-m running speed tests (times measured). The study comprised 85 adolescents (38 girls) aged 13.0-16.9 years from the Healthy Lifestyle in Europe by Nutrition in(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)
BACKGROUND Excessive television (TV) viewing might play an important role in the development of cardiovascular disease (CVD). The aim of this study was to examine the independent associations between TV viewing and CVD risk factors in adolescents. METHODS A sample of 425 adolescents, aged 13- to 18.5-year-old, was included in this study. Body mass index(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)
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)
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 Down syndrome (DS) has been described as one of the main contributors for low bone mineral density (BMD). Physical activity (PA) is a key factor in skeletal health and thus, PA levels might be associated to the risk of developing osteoporosis. Therefore, the aims were (1) to describe PA patterns in adolescents with DS compared to their(More)
