      Benítez-Porres, Javier; Correas-Gómez, Lorena; Carrillo-de-Albornoz, Margarita; Martín-Sanz, Norma; Alvero-Cruz, Jose Ramon; [et al.] (2014-06-26)
      Introduction The association between physical activity (PA) and resting blood pressure (BP) is poorly understood in adolescents (Kelley, Kelley, & Tran, 2003), since several variables such as body composition, maturation ...
    • Construct validity of the physical activity questionnaire for adolescents (paq-a): maximal oxygen uptake 

      Benítez-Porres, Javier; Dorado-Guzmán, Manuel; Barrera-Expósito, Jesús; Correas-Gómez, Lorena; Alvero-Cruz, Jose Ramon; [et al.] (2015-06-22)
      Introduction: The Physical Activity Questionnaire for adolescents (PAQ-A) is a cost-effective tool to assess physical activity (PA) patterns during adolescence and it has been widely used in research and field settings. ...

      Benítez-Porres, Javier; Raya, Juan Francisco; Correas-Gómez, Lorena; Carrillo-de-Albornoz, Margarita; Alvero-Cruz, Jose Ramon; [et al.] (2014-06-26)
      Introduction: Internal abdominal fat (IAF) measured by dual energy X-ray absorptiometry (DXA) has been proposed as subrogate of visceral adipose tissue, which is a cornerstone measurement for screening of metabolic ...

      Alvero-Cruz, Jose Ramon; Fernández-Vazquez, Rosalia; Fernández-García, José Carlos; Carnero, Elvis A. (2014-01-30)
      INTRODUCTION: Significant scientific evidence documents the deleterious effects of reduced total body water (TBW) on endurance exercise performance, however, the influence of hypohydration on muscular strength, power and ...
    • Longitudinal differences of physical activity and adiposity in adolescents: a 2-year follow-up 

      Benítez-Porres, Javier; Alvero-Cruz, Jose Ramon; Barrera-Expósito, Jesús; Dorado-Guzmán, Manuel; Carnero, Elvis A. (2014-06-26)
      It is commonly believed that boys are more physically active than girls, which could affect body composition changes during adolescence. One major point not always considered or controlled is the maturational differences ...
    • Maturation level in adolescents: effects on body composition and physical activity changes 

      Benítez-Porres, Javier; Alvero-Cruz, Jose Ramon; Moore, Justin B.; Carnero, Elvis A. (2016-03-29)
      Background and aims: Longitudinal studies help move researchers closer to understanding determinants and mediators of maturation, physical activity (PA) and adiposity. The aim of this study was to longitudinally explore ...
