The influence of triazolam and flunitrazepam on isokinetic and isometric muscle performance

The influences of two benzodiazepines (triazolam 0.25 mg and flunitrazepam 2 mg) on isokinetic and isometric muscle performance and on cardiovascular parameters were examined after a standard period of sleep. A randomized and double-blind test procedure was used (n = 15). Triazolam had no significant (p < 0.05) influence on either of the test conditions. Administration of flunitrazepam significantly lowered values for maximal isometric force and for the cardiovascular parameters. It was concluded that triazolam does not influence performance. On the other hand, flunitrazepam does influence a number of strength characteristics and cardiovascular parameters in effort situations. © 1994 Taylor and Francis Group, LLC.
