Ridges in fingernails can run horizontally or vertically.1 They are common and harmless, but some fingernail ridges—particularly horizontal ones—can indicate a health problem such as a thyroid issue.
For some people, going for a run can trigger what's known as a "runner's high," a short-lasting feeling of euphoria or relaxation. But for others, running can trigger something far less pleasant: a headache.
For people with osteoarthritis (often called the "wear and tear" form of arthritis), golf helps maintain joint range of motion, strength and endurance, and contributes to mental health and well-being.
Repetitive Pitching Decreases the Elbow Valgus Stability Provided by the Flexor-Pronator Mass: The Effects of Repetitive Pitching on Elbow Valgus Stability
Baseball pitching induces a large elbow valgus load, stressing the ulnar collateral ligament. Flexor-pronator mass contraction contributes to valgus stability; however, repetitive baseball pitching may weaken the flexor-pronator mass contractile function. The present study investigated the effects of repetitive baseball pitching on the medial valgus stability measured using ultrasonography.
