Abstract

The aim of this study was to evaluate the effect of isokinetic training on healthy students’ and on students’ after knee injuries functional status (knee extensor and flexor muscles strength, resistance and balance). In a study participated 24 students. I group comprised of 12 students (mean age 21,2 ± 2,86 years) after knee injuries, II group comprised of 12 healthy students (mean age – 20,6 ± 1,62 years) without knee injuries. Both groups participated in isokinetic training for 10 work days. Knee muscles strength and resistance were measured using an isokinetic dynamometer “Biodex System 4 Pro”. Data were analyzed using Student’s t test. Statistical significance was defined as p<0,05. The research showed that after isokinetic training knee flexor muscles strength increased in both groups (in I group – 9,7 Nm, in II group – 13,7 Nm). Knee flexor muscles resistance increased 165,6 J in I group and 179,5 J in II group. Also during this period increased knee extensor muscles resistance, decreased muscle imbalance. Research showed that first group knee flexor and extensor muscles function status differs from second group (p<0,05). After isokinetic training knee flexor and extensor muscles strength, resistance and balance increased in both groups, but in second group increased more (p<0,05).
