Vitamin D plays an important role in the regulation of calcium and phosphorus absorption by the organism. It also helps keep the brain and immune system working. Researchers at the Federal University of São Carlos (UFSCar) in Brazil and University College London (UCL) in the United Kingdom have now shown that vitamin D supplementation reduces the risk of dynapenia in older people by 78%.  Dynapenia is an age-associated loss of muscle strength. It can be partially explained by [...]

Scientists affiliated with the Department of Physical Education’s Human Movement Laboratory (Movi-Lab) at São Paulo State University (UNESP) in Bauru, Brazil, are using artificial intelligence to help diagnose Parkinson’s disease and estimate its progression. An article published in the journal Gait & Posture reports the findings of a study in which machine learning algorithms identified cases of the disease by analyzing spatial and [...]

Researchers at the University of São Paulo (USP) in Brazil analyzed data from 43 scientific articles describing the effects of COVID-19 on athletes and concluded that while the disease was asymptomatic or mild in the vast majority of cases (94%), about 8% of the subjects concerned had persistent symptoms affecting their performance and potentially preventing a return to training and competing. The data they analyzed referred to some 11,500 athletes, including amateurs and [...]

There is growing evidence that the gut microbiota, the collection of bacteria, viruses, fungi and other microorganisms that colonize the gastrointestinal tract, can influence the development and progression of neurodegenerative disorders. Two recently published articles by Brazilian researchers reinforce this hypothesis and describe a mechanism by which the development of Parkinson’s disease may be due in part to an imbalance between pathogenic and beneficial bacteria in the intestines [...]

In an editorial in the British Journal of Sports Medicine, Bruno Gualano, a professor at the University of São Paulo (Brazil), reviews what scientists know about the relationship between regular exercise and recovery from COVID-19 complications. “As speculated at the start of the pandemic and now consistently proven, physically active people tend to experience a milder form of the disease caused by SARS-CoV-2. Taken together, all research on the subject suggests that the risk of [...]

Researchers have developed a novel device that incorporates virtual reality as a complement to conventional motor therapy for stroke patients and individuals with neurodegenerative diseases. The wearable device, called Biomechanics Sensor Node (BSN), is designed to capture user data and control virtual environments. The device, as well as a new software solution integrating the BSN with Unity Editor, a game engine and virtual world-building program, was developed as the result of a recent [...]
