NUTR 313 Lecture Notes - Lecture 12: Prostate Cancer, Skeletal Muscle, Blood Sugar
Document Summary
Physical activity any movement of skeletal muscles that requires energy. Exercise physical activities that are planned, repetitive, and intended to improve physical fitness. Physical fitness the ability to perform moderate to vigorous physical activity without undue fatigue. Muscle-strengthening activities physical activity that increases skeletal muscle strength, power, endurance, and mass: ex: lifting weights, using weight machines, calisthenics. Enhances heart and lung function: muscular fitness. Encompasses strength, endurance, and power: flexibility. Enhances balance and stability: need to warm up and cool down. Atp (adenosine triphosphate) main energy currency for cells: used to promote ion pumping, enzyme activity, and muscular contraction. Adp (adenosine diphosphate) breakdown product of atp: synthesized into atp using energy from foodstuffs and a phosphate group. Anaerobic metabolism supplies energy for short bursts of intense energy. B vitamins support energy metabolism and red blood cell health. Calcium intake is important, especially in women.
