The level of explosive strength of the lower limbs in the group of the students

Abstract

Present study detects current state of the level of explosive strength
of lower limbs of university students attending studies at Department
of Physical Education and Sports, Faculty of Arts, Matej Bel
University in Banská Bystrica. Students attended subject focused on
diagnosis and research in sport. The sample consisted of 13 men
(age ± 20.14 years; height ± 176.9 cm; weight ± 71.4 kg) and 4
women (age ± 19.87 years; height ± 168.4 cm; weight ± 58.2 kg).
Measurement was realized on 11th of March in 2016 (in the
beginning of the summer semester 2015/2016). We diagnosed three
vertical jumps - 10 plyometric vertical jumps – PJ (Height, Time of
Contact, Reactivity and Stiffnes); Squat Jumps – SJ (Height, Power,
Force and Velocity; 3 repetitions) and Counter Movement Jumps-
CMJ (Height, Power, Force and Velocity; 3 repetitions). Results
present following mean values: mean value of CMJ test was 34.84
cm, mean value of SJ test was 30.74 cm and mean value in PJ test
realized by 17 students (10 repetitions) was 9.65 cm with mean time
of contact with the ground at the level of 110. 54 ms. Results were
put to correlation analysis where we detected mutual dependence
between all variables. We found out high unit of mutual dependence
where values of correlation coefficient were 0.913465 – 0.930023.
