Positive reinforcement
Refers to consequences that increase the probability of occurrence of a desired behavior or operant, postivie gives something to the client in response to his behavior
Negative reinforcment
takes away something in response
Obestiy definition
BMI > 30 (kg/m2) ro waist girth >40 inches for men and 35 inches for women.
Which of the following components of the production of force changes throughout the movement of a bicep curl with a free weight?
a. Horizontal distance from the weight to the elbow
b. Torque
c. Weight
d. Both a and b
The horizontal distance and the torque change. Since the horizontal distance from the weight to the elbow changes, so does the torque produced throughout the motion, even though the weight stays the same. This then changes the resistance throughout the motion.
