The presented study focuses on the impact
analysis of a specific training programme primarily focusing on plyometric
exercises for the lower limb explosive power, and the selected parameters of
swimming turns. The tested set consisted of performance swimmers (n = 20, men n
= 12 and women n = 8) in the average age of 17.3 years, average height of
174.2cm, and average weight of 65.8kg. The tested set was divided into two
smaller sets. The experimental set (n = 10) used the training process as an
extra experimental factor and the supervision set (n = 10) carried out only the
main contents of the training process. The specific training schedule was
applied during the period of 8 weeks, three times a week for 20 minutes. The
effectiveness of the experimental factor was tested through a selected set of
tests, focusing primarily on the lower limb explosive power. Three of the tests
were conducted on the dryland using the Myotest machine: T1 – Squat jump (SJ),
T2 – Countermovement Jump (CMJ) and T3 – Plyometric jump (PJ). The tests
conducted in the swimming pool were: T4 – max. length of floating up after the
push off from the turning wall, and T5 – the length of push off after 25m of
breaststrokes in the maximum speed with a push off from the wall of maximum
floating up. The results pointed out a proportionally higher increase in the
experimental set, in which the average percentile improvement of the jump
height amounted to 17.7% in T1 (the changes in the supervision set were 0.7%);
in T2 the jump height was increased by 22% (the changes in the supervision set
were 0.6%); in T3 the time of contact increased by 18.5% (the supervision set
showed a decrease by 1.2%), T4 by 14.9% (the changes in the supervision set
were 4.1%) and in T5 by 22.7% (the changes in the supervision set were 11.0%).
Kendall correlation coefficient (r), pointed out the average value of the
correlation coefficient between the experimental factor and the individual
tests as follows: T1: r = 0.39, p<0.05; T2: r = 0.41, p<0.05; T3: r =
0.43, p<0.05, T4: r = 0.38, p<0.05 a T5: r = 0.41, p<0.05. In
conclusion, practice, improvement, and affectivity of the swimming turn can
affect the swimmers’ performance in races and improve it.
