Knee extensor and flexor muscle (ie, thigh) weaknesses are well-established consequences of anterior cruciate ligament (ACL) tears treated with ACL reconstruction (ACLR). To learn more, Canadian researchers assessed bilateral knee extensor and flexor concentric isokinetic peak torque at 90° per second semiannually in 186 youth (106 injured, 80 controls) for 2 years.

Sarcopenia is characterized by the progressive loss of skeletal muscle mass and poses a significant health challenge for older adults by increasing the risk of disability and decreasing quality of life. With the increasing number of older adults, sarcopenia has the potential to become a major public health burden across the globe. Yoga is considered a low-risk and beneficial exercise for older adults. 

Getting at least 30 minutes of daily summer sun in the first year of life may mean a lower relapse risk for children who are diagnosed with multiple sclerosis (MS) later, according to a study published in Neurology Neuroimmunology & Neuroinflammation. The study also found if a child’s biological mother had at least 30 minutes of daily sun during the second trimester of pregnancy, the child had a lower risk of MS relapses.

In this secondary analysis, there was no difference between morning (AM) and afternoon/early evening (PM) exercisers in blood glucose, insulin, body composition, or muscular strength following 12 wk of supervised exercise. However, examining within-group changes, glucose area under the curve (AUC) was significantly reduced in PM exercisers, but not in AM exercisers. 

Reductions in balance performance, hip strength, and ankle function along with increases in disablement and injury-related fear are among the many motor-behavioral and sensory-perceptual impairments associated with chronic ankle instability (CAI). Both balance training (BAL) and hip strengthening (HIP) can improve balance, but how do the 2 modalities compare?
