Is caffeine ergogenic? If so what does it do to improve performance?
Yes. It improves calcium release increasing force of contraction and it spares glycogen by stimulating the breakdown of lipids.

C: for maintaining positive nitrogen balance in aerobically trained individuals
A: for maintaining a positive nitrogen balance in resistance trained individuals
C: for maintaining positive nitrogen balance in aerobically trained individuals
Is baking soda ergogenic? If so, what does it do to improve performance?
Yes, increases acid buffering
Creatine supplementation increases muscle power by increasing:
ATP production
Are amphetamines ergogenic? If so, what does it do to improve performance?
No

D: 50-100 g of carbohydrate 2-5 hours prior to the event
D: 50-100 g of carbohydrate 2-5 hours prior to the event

The set point theory posits that:
weight changes are compensated by changes in metabolism to maintain body weight
Spot reduction by exercising a specific anatomical location: (select all that apply)
A: can increase muscle tone, which can give a slimming appearance, but fat is not preferentially burned at that site.
B: is based on the fact that local changes in phosphates, CO2, and lactate stimulate local adipose to mobilize
C: is effective in selectively removing fat stores
A: can increase muscle tone, which can give a slimming appearance, but fat is not preferentially burned at that site.

B: during the first several days the majority of the weight loss is water.
C: thermic effect of eating will increase
D: both body fat and fat free mass will be lost
