Exercise is structured physical activity performed to improve health, fitness, and overall physical function. It enhances cardiovascular endurance, muscular strength, flexibility, and coordination while supporting weight management and metabolic health. Regular exercise boosts mood, reduces stress, and lowers the risk of chronic diseases. It includes activities like strength training, aerobic workouts, mobility drills, and sports, each contributing to improved performance and

Exercisability refers to an individual’s ability to perform physical activity safely and effectively based on their fitness level, health status, and physiological capacity. It reflects how well the body can tolerate exercise, adapt to workload, and recover afterward. Factors such as cardiovascular function, muscle strength, mobility, motivation, and medical conditions influence exercisability, making it an important measure in training, rehabilitation, and overall health ass

The agonist-antagonist ratio describes the balance of strength or activation between opposing muscle groups during movement, such as quadriceps versus hamstrings. A healthy ratio supports joint stability, control, and performance, while imbalances can increase the risk of injury or limit movement efficiency. This ratio is often assessed in rehabilitation and sports science to guide training, restore balance, and optimize muscular coordination and function.

Psoriasis is a chronic autoimmune condition that speeds up the life cycle of skin cells, causing thick, red, scaly patches that can itch or hurt. It commonly affects the scalp, elbows, knees, and lower back. Flare-ups may be triggered by stress, infection, cold weather, or certain medications. Though not contagious, psoriasis is long-term and often cyclical. Treatment includes topical creams, light therapy, and medications that reduce inflammation and regulate the immune resp
