Knee osteoarthritis pain is often only treated as a problem of joint degeneration, but growing evidence suggests the gut may also play a role in how that pain is perceived. Researchers tested whether inulin, a prebiotic fiber, could reduce symptoms on its own or when paired with a digital physiotherapy program. The trial randomly assigned 136 adults with knee osteoarthritis to four groups: 20 grams of inulin per day, an app-based physiotherapy exercise program, both treatments together, or maltodextrin as a placebo. The researchers measured average knee pain, lower-body function using chair-s... arthritis gut microbiome prebiotics
Read moreImmersing sore muscles in hot or cold water is a common recovery practice among athletes and other active people. However, most research on its effects has focused primarily on men, leaving women underrepresented in this area of study. A recent study found that neither hot nor cold water immersion improved muscle recovery in women after intense exercise. Researchers asked 30 healthy young women to complete a demanding jumping workout to induce muscle soreness and temporary muscle damage. Immediately after the workout, and again two hours later, participants sat in cold, hot, or no water for 10... cold stress exercise muscle

Watch nowTaurine is an amino acid that participates in immune health and neurological function. Findings from a recent study suggest that taurine influences longevity. Mice that received supplemental taurine lived as much as 12 percent longer than those that didn't. Researchers conducted a multi-part experiment in several species. First, they measured blood taurine concentrations in mice, monkeys, and humans at different ages and found that taurine decreased in all three species over time. Notably, taurine concentrations were 80 percent lower in older adult humans than in young children. Then they gav... aging inflammation dna damage mitochondria taurine

Watch nowAerobic exercise provides many health benefits, including a reduced risk of cardiovascular, metabolic, and other chronic diseases. Some of these benefits are due to adaptations in skeletal muscle that arise from the repair of cellular damage produced by the demand of exercise. One team of researchers aimed to determine the effects of antihistamines on muscle adaptation following acute and chronic high intensity interval training, often referred to as HIIT. Histamine is an organic molecule that acts as a neurotransmitter in the brain and spinal cord, while also regulating gut and immune functio... exercise

Findings from a new study suggest that regular physical activity also reduces the risk of developing COVID-19. Most international public health organizations recommend that adults of all ages engage in at least 150 minutes of moderate intensity aerobic physical exercise or at least 75 minutes of vigorous intensity aerobic physical exercise each week, or an equivalent combination of both. Most adults fall far short (https://jamanetwork... covid-19

Watch nowA sedentary lifestyle is associated with a 77% increased risk of kidney cancer and a 73% increased risk of bladder cancer independent of obesity and other health lifestyle factors. Several biological mechanisms have been proposed to account for an association between physical inactivity and cancer. These include an increase in circulating levels of sex hormones, increased chronic inflammation, impaired insulin sensitivity, impaired immune surveillance and responsiveness, increased adiposity, and a dysregulated adipokine milieu. While this study found the association between physical inactivity... exercise cancer insulin
