Three Types of Muscle 1. Skeletal 2. Cardiac 3. Smooth 2 forms of Hypertrophy 1. In series 2. In parallel Primary mechanism for hypertrophy associated with resistance training Increase in number of sarcomeres in parallel How is in series hypertrophy achieved Increasing the number of sarcomeres- basic functional unit of muscle- along length of fiber Though in series hypertrophy does take place in humans, it only occurs in extreme cases such as Following immobil...

AAMC FL3 BB Exam 2024 Individual M has longer limbs and muscles than Individual N. Both individuals lift the same amount of weight from the ground to their shoulders an equal number of times. If all repetitions were completed in synchrony, which statement about the amount of work completed by the individuals is true?

Proprioception - Answer- The body's ability to to sense the relative position of adjacent parts of the body Ex: when walking our feet give us proprioception about the type of surface we are on. Mechanoreceptors - Answer- specialized structures that recognize pressure in tissue and transmit signals to sensory nerves. Muscle Spindles - Answer- sensory receptors in the muscles that are parallel to the muscle fibers and are sensitive to change in muscle length. Spindles stretch with muscle...

Power equation= P=fv f=force v=velocity Which of the following is LEAST likely to occur in a muscle fiber that is metabolizing anaerobically? A.Fermentation of glucose to lactic acid B.Phosphorylation of ADP within the electron transport chain C.Depletion of stores of glycogen D.Acidification of the cytoplasm B fast-twitch muscle Muscle fibers that contract rapidly and powerfully, with little endurance. They have few mitochondria and large glycogen reserves. They depen...

Target Heart Rate Equation correct answer: 220 beats/min - 20 (age) = 200 (estimated max. heart rate) Max heart rate - 60 (resting heart rate) = 140 x .75( HR range .6-.9) + 60(resting heart rate) = Target heart rate William's Approach correct answer: - Premise is that cause of most low back pain is acquired by walking upright in a straight position - Williams states that normal posture is with *knees bent and torso slightly bent foward* - All activities should be geared to reducing lum...
