Hamstring stretching exercises performed in the working place are effective for increasing hamstring muscle extensibility. This increase generates a more aligned thoracic curve and more anterior pelvic inclination when maximal trunk flexion is performed.

BackgroundThe al-Andalus physical activity intervention study is a randomised control trial to investigate the effectiveness of a land- and water-based exercise intervention for reducing the overall impact of fibromyalgia (primary outcome), and for improving tenderness and pain-related measures, body composition, functional capacity, physical activity and sedentary behaviour, fatigue, sleep quality, health-related quality of life, and cognitive function (secondary outcomes) in women with fibromyalgia.Methods/DesignOne hundred eighty women with fibromyalgia (age range: 35-65 years) will be recruited from local associations of fibromyalgia patients in Andalucía (Southern Spain). Patients will be randomly assigned to a usual care (control) group (n = 60), a water-based exercise intervention group (n = 60) or a land-based exercise intervention group (n = 60). Participants in the usual care group will receive general physical activity guidelines and participants allocated in the intervention groups will attend three non-consecutive training sessions (60 min each) per week during 24 weeks. Both exercise interventions will consist of aerobic, muscular strength and flexibility exercises. We will also study the effect of a detraining period (i.e., 12 weeks with no exercise intervention) on the studied variables.DiscussionOur study attempts to reduce the impact of fibromyalgia and improve patients' health status by implementing two types of exercise interventions. Results from this study will help to assess the efficacy of exercise interventions for the treatment of fibromyalgia. If the interventions would be effective, this study will provide low-cost and feasible alternatives for health professionals in the management of fibromyalgia. Results from the al-Andalus physical activity intervention will help to better understand the potential of regular physical activity for improving the well-being of women with fibromyalgia.Trial registrationClinicalTrials.gov ID: NCT01490281

RESUMEN:El objetivo principal del estudio fue determinar la morfología del raquis e inclinación pélvica en bipedestación en tres grupos de ciclistas de distintas edades, con un volumen de entrenamiento y experiencia similares. Un total de 65 ciclistas fueron divididos en tres grupos de edad: grupo 1 (≤ 30 años; n = 20); grupo 2 (entre 31 y 40 años; n = 25); y grupo 3 (≥ 41 años; n = 20). Posteriormente se les evaluó la morfología sagital del raquis torácico, lumbar e inclinación pélvica en bipedestación, mediante el sistema Spinal Mouse. Los valores angulares medios para el raquis torácico, lumbar e inclinación pélvica para el grupo 1 fueron: 46,60 ± 10,09º; -26,40 ± 7,17º; 13,20 ± 4,94º; para el grupo 2: 47,64 ± 8,58º; -26,92 ± 6,34º; 12,24 ± 4,45º; y para el grupo 3: 50,75 ± 12,77º; -20,70 ± 10,10º y 8,15 ± 8,21º. Se encontraron diferencias significativas en el raquis lumbar e inclinación pélvica en los grupos 1 y 2, con respecto al 3. En conclusión, la edad es un factor que condiciona la morfología del raquis e inclinación pélvica en ciclistas que presentan los mismos años de práctica y volumen de entrenamiento en ciclismo.
