Question 1

Body Composition

Answer 1

Refers to the proportion of body fat to lean body tissue
% Fat vs. total body weight
total body weight. = bone, muscle, fat
fat weight = % of wt. contributed to fat tissue
Male vs. female - % fat recommendation

Question 2

Strength and Endurance

Answer 2

Strength- amount of force exerted by a group of muscles

Endurance- ability to maintain a contraction over a period of time

Question 3

forced rep

Answer 3

A rep is considered “forced” when a bodybuilder reaches muscle failure during a set and has a training partner assist in completing past the normal point of failure and therefore fatigues more muscle fiber, as well as those that are normally used, thereby stimulating more complete growth and muscle density.Apr 5, 2006

Question 4

benefits of warming up

Answer 4

Rehearsal of movement
Elevation of body temperature
increase dissociation of oxygen from hemoglobin and myoglobin
lowering of activation energy rates of metabolic chemical reactions
increase muscle blood flow
reduction in muscle viscosity
increase sensitivity of nerve receptors
increase speed of nervous impulses
Reduces incidence and likelihood of musculoskeletal injuries
Supplies adequate blood flow to heart
warm up of two minutes prior to sudden exertion can decrease relative myocardial hypoxia and decrease blood pressure during exercise.
warm up may precede strenuous exercise by as much as 10 to 15 minutes and still decreased arrhythmias indicative of inadequate oxygen to the heart.
warm up may be particularly crucial for those with a degree of underlying coronary artery disease.
although the original study examined men ages 21 to 52 years who were asymptomatic to heart disease
