The UC Berkeley team has developed a set of principles that apply to animal locomotion of all kinds, from running to flying. Their research has led to breakthroughs in robot design, ergonomics, and even computer animation, with potential applications in fields like engineering and Pixar Animation Studios.
Researchers have discovered that stimulating nerves can alter cortical responses, leading to potential therapeutic approaches for stroke victims. By bypassing damaged brain areas, patients may regain at least some movement control.
A new therapy, using a CPAP device, reduces hypernasal speech in people with repaired cleft palates by strengthening the muscles of the soft palate. The study, conducted on 43 subjects aged under 19, shows significant improvement after eight weeks of treatment.
A study published in the British Journal of Sports Medicine found that sports massage has little effect on muscle power and blood lactate levels, contradicting its long-held use as a recovery aid. However, participants who received massage reported feeling significantly better than those who rested.
A University of Toronto study has shown that botox injections can effectively relieve headache pain, especially for patients with neck-related headaches. The treatment group experienced a substantial reduction in pain and improvement in range of motion after just four weeks.
A University of Florida researcher has finally shed light on the side effects of creatine, a popular muscle enhancer. The study found that creatine increases both overall water content and the ratio between intracellular and extracellular water, leading to an imbalance that can cause dehydration, heat illness, and kidney problems.
A study published in the Journal of Applied Physiology reveals that a specific pathway controls the breakdown of proteins regulating muscle type. The ubiquitin/proteasome pathway determines which proteins are degraded, allowing for the switching of muscle type during exercise training or constant contraction.
A study found that creatine supplementation improved the performance of elite male swimmers in a 50-meter swim, but not female swimmers. The research suggests that creatine may enhance muscle energy during high-intensity exercise by increasing phosphocreatine levels.
Researchers have developed tiny implants, called BIONs, that can be injected into muscles to stimulate them and prevent wasting. The implants use radio signals to activate electrical stimuli, offering a potential breakthrough in treating stroke patients who are at risk of serious complications such as thrombosis and muscle dislocation.
Researchers at Johns Hopkins University developed HARP MRI to provide detailed heart muscle images in minutes, not hours. The system uses harmonic phase magnetic resonance imaging and software modifications to produce high-quality images of heart function.
A new Implantable Pulse Generator (IPG) device has been developed to help patients with paralyzed vocal folds breathe on their own. The device was recently implanted in a Missouri woman, who was able to have her tracheotomy tube removed after 18 months of successful ventilation.
A study by UMass researchers found that athletes taking andro steroid may experience mood changes and affect their brains. The steroid alters neurotransmitters and stimulates libido and aggression, similar to testosterone.
Scientists used a new measurement technique to study muscle movement at the molecular level, shedding light on how myosin and actin interact. The technique, called luminescence resonance energy transfer, provided direct evidence for the lever-arm model of muscle contraction.
Research reveals that specific growth factors can speed up muscle regeneration and quicken healing in animal models. The findings hold promise for treating various types of muscle injuries in humans, including those affecting athletes who risk ending their careers due to disabilities caused by muscle injuries.
