Slow red oxidative fibers (type 1) have high myoglobin content, have mitochondria and capillaries, contract slowly and are for resistance to fatigue. Muscle tissue is classified into three types according to structure and function: skeletal, cardiac, and smooth ( Table 4.2 ).

The result is a sustained muscle contraction, multiple motor unit summation; controls the force of contraction more precisely, stimuli that produce no observable contractions, the stimulus at which the first observable contraction occurs, strongest stimulus that increases contractile force, due to spinal reflexes that activate first one group of motor units and then another in response to activated stretch receptors in teh muscles; does not produce active movements but keeps the muscles firm, the muscle tension developed overcomes the load and muscle shortening occurs, muscle tension develops but the load is not moved, a unique high energy molecule stored in muscles; tapped to regenerate ATP while other metabolic pathways adjust to the sudden high demand for ATP, catalyzes the transfer of phosphate from CP to ADP, the initial phase of glucose breakdown; pathway occurs in both presence and absence of oxygen; glucose broken down to two pyruvic acid molecules, blood flow and oxygen delivery are impaired during vigorous muscle contraction; pyruvic acid is converted, the overall process where pyruvic acid generated durring glycolysis is converted to lactic acid, Respiration that requires oxygen and mitochondria; during rest and light to moderate exercise, the length of time a muscle can continue to contract using aerobic pathways, the point at which muscle metabolism converts to anaerobic glycolysis, Inability of muscle to maintain its strength of contraction or tension; may be related to insufficient oxygen, depletion of glycogen, and/or lactic acid buildup, excess postexercise oxygen consumption (EPOC)/oxygen debt, the extra amount of oxygen that the body must take in for restorative processes, contract slowly, have slow acting myosin ATPases, and are fatigue resistant, contract quickly, have fast myosin ATPases, and have moderate resistance to fatigue, contract quickly, have fast myosin ATPase, and are easily fatigued, such as Lab 9 Report Muscle Physiology Lab Report-Complete the Labster Skeletal muscle simulation and answer the questions below 1) What is the importance of Myosin ATPase?
