The purpose of this study was to evaluate the effect of eight weeks strength and

plyometric trainings on knee joint position sense. In this study, 45 male students

(21.7±2.17years, weight 69.7±7.89 kg, and height 177.2±5.83cm) volunteered

and selected as subjects to participate in this semi-empirical study. Subjects

divided in three groups include strength (n=15), plyometric (n=15) and control

(n=15). Strength group trained squat, leg flexion and leg extension and

plyometric group trained depth jump, Split squat jump, rim jump and box to box

depth jump. Joint position sense measured at three angles 30, 45 and 60

degrees in knee joint by Biodex Isokenitic system 3. One-way ANOVA was

used for analysis of data. Results of study showed that trainings significantly

improve the joint position sense in initial angel (30degree) on active

reproduction and in initial and final angels (30 and 60 degrees) on passive

reproduction. In addition, comparison of trainings revealed that strength training

in 30 degrees and plyometric training in 30 and 60 degrees significantly improve

the joint position sense. Between two methods of training only on passive

reproduction at 60 degree, significantly difference was observed (p≤0.05).

These protocols can use in rehabilitation to improve proprioception and

neuromuscular coordination.
