Cardiorespiratory, metabolic and muscular responses during a video-recorded aerobic dance session on an air dissipation platform

Background: Aerobic dance (AD) is an appropriate physical activity for improving cardiorespiratory fitness. This study aimed to compare cardiorespiratory and metabolic responses, and muscle fatigue between an air dissipation platform (ADP) and a hard surface during a video-recorded AD session. Methods: 25 healthy young women (23.3 ± 2.5 years) completed three sessions. In session 1, participants performed an incremental test to exhaustion on a treadmill. One week after session 1, participants were randomly assigned in a crossover design to perform video-recorded AD sessions on an ADP and on a hard surface (sessions 2 and 3). Cardiorespiratory and metabolic responses were assessed during AD sessions. Muscular fatigue was measured before and after AD sessions by a countermovement jump test. Results: Significantly higher heart rate, respiratory exchange ratio, pulmonary ventilation, ventilatory oxygen equivalent, and ventilatory carbon dioxide equivalent were observed on an ADP than on a hard surface (p 0.05). Conclusions: Video-recorded AD on an ADP increased the cardioventilatory and metabolic responses compared to a hard surface, preventing further muscle fatigue

Aerobic Dance on an Air Dissipation Platform Improves Cardiorespiratory, Muscular and Cellular Fitness in the Overweight and Obese Elderly

Background: Obesity is a global health problem associated with a high number of comorbidities that decrease functional capacity, especially in elderly people. Aerobic dance is considered a viable strategy to prevent the effects of aging, mainly in obese and overweight elderly people. This study aimed to evaluate the effects of aerobic dance on an air dissipation platform (ADP) on body composition, oxidative stress and muscular and cardiorespiratory fitness in elderly people. Methods: In total, 32 elderly adults (67.1 ± 3.6) were divided into 3 groups based on body mass index: healthy (HG), overweight (OWG) and obese (OG). Training program of aerobic dance on an ADP was carried out twice a week for 12 weeks. Results: OWG (p = 0.016) and OG decreased their weight (p < 0.001). There was a significant decrease in malondialdehyde concentrations in all experimental groups (p < 0.05). OWG and OG significantly improved their peak oxygen uptake (p < 0.01). HG increased the vertical jump height (p < 0.05), and HG and OG improved the power output of the lower extremities (p < 0.05). Conclusions: The aerobic dance on an ADP may be an effective alternative to lose weight, prevent oxidative stress and improve cardiorespiratory fitness in obese and overweight elderly people

Campos de Níjar : treinta años después

Se pretendía que la experiencia fuera una alternativa a los típicos viajes de fin de estudios y una culminación de todas las actividades interdisciplinares y salidas escolares. El punto de partida fue la obra literaria 'Campos de Níjar'; de Juan Goytisolo, y la idea de recorrer con los alumnos-as esta zona de Almería. Al igual que él hizo, reflejar en un libro las impresiones y vivencias experimentadas, contrastar la realidad actual con la observada por el autor hace 30 años. 81 sujetos (alumnos-as y profesores) de octavo de EGB del curso 1988-89 del Colegio Público Gerardo Diego de Leganés (Madrid). Fruto del trabajo surgió el libro que está estructurado en dos partes: Una primera escrita por el alumnado, donde en forma de diario se narra la experiencia desde las actividades realizadas a las sensaciones vividas pasando por las opiniones personales sobre algunos aspectos de la realidad observada. El alumnado se organizó en 7 equipos de trabajo formado cada uno por 10, 11 ó 12 personas. Cada uno de los profesores se encargó de la coordinación y seguimiento de un equipo. La segunda parte está elaborada por el equipo de profesores-as, se plantean los aspectos pedagógicos y didácticos de la experiencia. La experiencia ha resultado positiva, ya que se han cumplido los objetivos que se pretendían, que los alumnos y alumnas de octavo, conociesen la más reciente historia de España. Que contrastasen el ayer más cercano y el hoy, valorando los cambios que se han producido, conocer un ecosistema relativamente virgen declarado recientemente parque natural y tomar conciencia social y ecológica.Ministerio Educación CIDEBiblioteca de Educación del Ministerio de Educación, Cultura y Deporte; Calle San Agustín, 5 - 3 Planta; 28014 Madrid; Tel. +34917748000; Fax +34917748026; [email protected]

Similar Slow Component of Oxygen Uptake and Ventilatory Efficiency between an Aerobic Dance Session on an Air Dissipation Platform and a Constant-Load Treadmill Test in Healthy Women

There is a lack of evidence about the slow component of oxygen consumption (V.O2sc ) and ventilatory efficiency (slope VE·VCO2−1) during an aerobic dance (AD) session on an air dissipation platform (ADP) despite the key role played in endurance exercises. This research was designed to assess V.O2sc , ventilatory efficiency, and blood lactate concentration by comparing two exercise modes: AD session on an ADP versus treadmill test at a constant-load intensity of the first ventilatory threshold (VT1). In the first session, an incremental treadmill test was completed. In sessions 2 and 3, the participants were randomly assigned to the AD session on an ADP or to a treadmill constant-load test at VT1 intensity to determine their cardioventilatory responses. In addition, their blood lactate levels and ratings of perceived exertion (RPE, CR-10) were evaluated. No significant differences were found between the constant-load treadmill test and AD session on an ADP with respect to V.O2sc , VE VCO2−1 slope, and RPE (p > 0.05). Higher blood lactate concentrations were observed in an AD session on an ADP than in a constant-load treadmill test at 10 min (p = 0.003) and 20 min (p < 0.001). The two different exercise modalities showed similar V.O2sc and VE·VCO2−1 slope, even though the blood lactate concentrations were different
