摘要：AbstractThe tenacity, regarding perseverance and persistence, is a very important psycho-motric quality for all sports, but mostly for combat sports. Being a quality from the volitive sphere, the measure can only be proven post factum. The indirect, correlative testing offers true information, using a tenacity index based on the solicitation of the excito- inhibitory processes of the palm flexor effort (amplitude, period, consistence, visual control of the oscillation etc.). Our research points out the fact that the tenacity index in significantly higher (300.14) for the right-handed athletes than for the left-handed ones or ambidextrous ones (259.62), at the significance threshold F < F critic (1,16<1,76).
