factor
factor, in arithmetic, any number that divides a given number evenly, i.e., without any remainder. The factors of 12 are 1, 2, 3, 4, 6, and 12. Similarly in algebra, any one of the algebraic expressions multiplied by another to form a product is a factor of that product, e.g., a+b and a−b are factors of a2−b 2, since (a+b)(a−b)=a2−b2. In general, if r is a rootroot,

Q. Regarding risk-factor assessment? Hello, I am……….., I heard ACSM has recently issued a new edition of its exercise guidelines. Were any changes made regarding risk-factor assessment?A. Are you fitness professional? I understand that you are very much interested in food guidelines. It can be difficult to keep up with the latest guidelines and standards. This is particularly true this year, which has seen new USDA Food Guidelines in January, a revised Food Pyramid in May and, most recently, the release of the 7th edition of ACSM’s Guidelines for Exercise Testing and Prescription. The good news is that the ACSM risk factors have been minimally revised. For your reference, here is a summary of what has and has not changed for the 2006 edition. Q. Is obesity a risk factor for Dementia? A. The answer is YES.
