A

Chylomicrons, Very low-density lipoproteins (VLDL), Low-density lipoproteins (LDL), High-density lipoproteins (HDL)

67
Q

PA and Lipid Profile

A

Inverse relationship between PA level and TC and the TC/HDL-C ratio; Aerobic exercise= moderate increase in HDL-C; Effect of resistance training is equivocal.

68
Q

Tobacco

A

Smoking is largest preventable cause of disease and premature death (Linked to CHD, stroke, lung diseases, various cancers); More prevalent in Asia than USA or UK (~20-25% in USA and UK, ~40-70% in Malaysia and Indonesia)

69
Q

Diabetes Mellitus

A

Global epidemic, 1 in 4 U.S. adults (American Indians and Alaskan Natives have highest prevalence)

70
Q

Type 1 Diabetes

A

Exercise has little to no effect

71

A

Measure of hemoglobin receptor response

73
Q

Do we want high or low HDL and LDL?

A

HDL high (good cholesterol), LDL low (bad cholesterol, reduced by physical activity)
