A number of DQIs have emerged, albeit their associations with health-related outcomes are debated. The aim of the present study was to assess whether adherence to diet...
Article
Objective: To examine the association between cardiorespiratory fitness (CRF) at baseline and cardiovascular disease (CVD) risk in 6- to 10-year-olds (cross-sectional) and 2 years later (8- to 12-year-olds [longitudinal]) and whether changes with age in CRF are associated with CVD risk in children aged 8 to 12 years. Patients and methods: Spanis...

Background: Push the manual wheelchair is one of the most important activities to the wheelchair users like individuals with spinal cord injury (SCI). The excessive or bad use of the upper limb would lead to biomechanical issues and pain. Whole-body vibration applied by vibratory platform (WBV) has been showing great results increasing muscular per...

Background: individuals with spinal cord injury (SCI) need upper limbs during activities of daily living that include transferring and propelling a wheelchair. A single session of Whole-body Vibration (WBV) has shown positive impact on musculoskeletal performance. Objective: To investigate the effects of one single session of WBV over the upper lim...
Article
Full-text available
Whole-body vibration (WBV) has shown positive results increasing electromyographic (EMG) activity and strength in a healthy population when applied to upper and lower limbs. The aim of this study was to verify if WBV increases the EMG signal of the upper limb muscles in patients with spinal cord injury (SCI). For this study, 15 patients with SCI we...
