1. What changes occur to the cardiovascular system as a result of endurance training in adults? (8 different adaptations and consequences).

2. What changes occur to the muscular system after strength training in adults? Be sure to include changes in muscle size, metabolic adaptations, neural adaptations, and effects on muscle fiber number. (minimum 4 changes).

3. Define the principles of specificity, training variables, overload, individualization, periodization, and reversibility in exercise prescriptions.

This is my Health and Kinesiology class homework, but I am so lost right now and I need help!

1. As a result of exercise, the following changes happen in the cardiovascular system:

Heart size : the heart mass and volume increase due to exercise. The left ventricle volume increases the most to adapt to supplying more blood to the body.
Heart rate : the resting heart rate increases in an individual undergoing training.
Stroke volume : stroke volume is the volume of blood pumped out by the heart in one constriction. This volume increases with training.
Cardiac output : when a person does endurance training vigorously, the cardiac output increases. Cardiac output is the product of heart rate and stroke volume.
Blood pressure : during the activities, blood pressure increases, but the resting overall blood pressure decreases.
Blood volume : endurance training increases the blood volume.
Number of blood vessels : the number of capillaries increases.
Size of blood vessels : the capillaries have wider openings to accommodate more blood volume.

Performing endurance training 1 hour prior to resistance training (aka concurrent training) may result in the following signaling mechanisms occurring in skeletal muscle: a. AMPK activating mTOR, resulting in an increase in protein synthesis b. AMPK inhibiting mTOR, resulting in an increase in protein synthesis c. mTOR activating AMPK, resulting in a reduction in protein synthesis d. AMPK inhibiting mTOR, resulting in a reduction in protein synthesis e. None of the above

1. What changes occur in flexibility with older adults? What important muscles should be stretched and strengthen in order to improve their activities of daily living (ADL)? 2. The Nurses’ Health Study found that for every 1 hr per week increase in walking, at an average pace, there was a 6% reduction in risk for hip fracture. What other exercises or exercise components may reduce fractures in older individuals.
