1 Isotonic -a muscle fiber contraction in which force production is unchanged when the muscle contracts causing movement of an external load.  Isokinetic -a muscle fiber contraction in which force production of the contraction is sufficient to overcome the external load.
HIV/AIDS. HIV Risk Behaviors. The risk of getting HIV varies widely depending on the type of exposure or behavior (such as sharing needles or having sex without a condom). Some exposures to HIV carry a much higher risk of transmission than other exposures.
With these statistics, your chances of being exposed to HIV in a single encounter is about 0.003% (less than half a percent chance) assuming you and your partner are heterosexual and do not inject drugs. Sorry about spouting off other stats, but I wasn't sure if you had other risk factors.
