force and time parameters of hand grip HGiso in different strength trained population. Testing sample of 189
examinees included: Control group consisted of the 1st year students of the Academy for Criminalistic and
Police studies (ACPS), Well trained – the 4th years students of ACPS and trained athletes from the discipline
Power Lifting. Methods: In order to assess the RFDHGiso different contractile characteristics we used
standardized equipment, i.e., a sliding device that measures isometric finger flexor force, with a tensiometric
probe fixed inside the device. Specific characteristics were measured according to Zatsiorsky et al. (2006)
and were showned by the S gradient parametres or F-t relation. Results: Multivariate statistical analysis
established that there is a significant difference at all contractile characteristics at the level of Wilks´ Lambda
0.739, F=2.378, p=0.000, among the observed sub-samples. Statistically significant difference was also
established at following variables regarding the observed sub-samples: in tF50%LHG F=4.023, p=0.019 and in
RFDBASICLHG F=3.133, p=0.046. Conclusion: The results of almost all obtained general and specific variables
and time parameters of hand grip explosive force showed that the maximal values are in Power Lifting. The fact
that statisticaly significant diferences was established for variable of basic explosivity of left hand grip force and also the smallest average values of RFDBASICLHG in the Control group isn`t surprising. Different tipes of snatches,
specific position and holding the bar with both hands in Power Lifting contributed the specific adaptation witch
resulted loss of functional domination of one hand or in equalising diabillity in both hands, for the level of maximal
isometric hand grip force as for the rate of force development of hand grip (RFDBASICHG) in both hand.
