Filter by:The goal of this observational study is to learn about the relation between grip position and maximal strength and power in wheelchair rugby and basketball athletes. The main question is to investigate the relationship between maximal isometric force, acceleration, and sprint time. Participants will - pull in their sport wheelchair against a force transducer - push in their sport wheelchair from a force transducer - accelerate as fast as possible with one push - accelerate as fast as possible over a distance of 20m Researchers will compare the wheelchair basketball against wheelchair rugby players to see if there is a difference in the parameters.
Osteoporosis is an age-related disease with progressive loss of bone, leading to fragile bone. It is one of the major health issues in elderly and causes medical, social and economic impacts globally. Patients with osteoporosis have high risk of osteoporotic fractures. Low-magnitude high-frequency vibration (LMHFV) is a non-invasive biophysical intervention providing whole-body mechanical stimulation. Previous studies showed that LMHFV is beneficial to muscle strength(1), postural control(2), balancing ability(3, 4), new bone formation(5-7), spinal bone mineral density (BMD)(8), and blood circulation(9). During the LMHFV treatment, elderly needs to stand upright on the platform for 20min/day. However, some elderlies with poor standing ability cannot stand for a long period. Therefore, the design of vibration platform is modified for the disabled patients and the efficacy of LMHFV on this group of elderlies will be verified. It is hypothesized that new design of LMHFV is beneficial to wheelchair users in terms of vertebral bone mineral density, muscle health and musculoskeletal functions.
