A COMPARISON OF RACE PERFORMANCE CHARACTERISTICS BETWEEN ELITE MALE 50-M AND 100-M FREESTYLE SWIMMERS BASED ON THEIR RESULTS
The aim of this research was to determine the differences in specific race performance characteristics of male swimmers in the 50-m and 100-m freestyle at the Serbia Open Championship 2017 (long-course). The overall sample included in this study consisted of 40 swimmers divided by a K-Means Cluster Analysis into three groups in relation to the results in the 50-m freestyle (G1_50, T50=23.53±.27 s, n=6; G2_50, T50=24.54±.33 s, n=18; G3_50, T50=25.52±.33 s, n=16), and 55 swimmers also divided into three groups in relation to the results in the 100-m freestyle (G1_100, T100=50.99±.82s, n=10; G2_100, T100=53.41±.48 s, n=17; G3_100, T100=56.13±1.32 s, n=28). The research results indicate that there is a difference in the specific race performance characteristics in relation to the achieved results in the 50-m freestyle, including: t10_50 (F=16.79, p=.000), SL2_50 (F=4.44, p=.019) and SI2_50 (F=13.49, p=.000), also in the 100-m freestyle, including: t10_100 (F=36.45, p=.000), SL1_100 (F=5.77, p=.005), SL2_100 (F=17.47, p=.000), SL3_100 (F=7.72, p=.001), SL4_100 (F=9.84, p=.000), SI1_100 (F=5.12, p=.009), SI2_100 (F=45.97, p=.000), SI3_100 (F=13.86, p=.000), SI4_100 (F=31.23, p=.000), SR1_100 (F=4.12, p=.022) and SR2_100 (F=6.37, p=.003). Based on these results we can draw the conclusion that swimmers who have better control over their race performance characteristics during all the segments of the race, including stroke length, stroke index and stroke rate have the potential of being faster in the 50-m and 100-m freestyle.
Is the handgrip strength influential factor on the competition result in elite male artistic gymnasts?
High handgrip strength in men’s artistic gymnastics is crucial, mainly for
improving performance and to potentially prevent injuries, as well as for the
fact that gymnasts body movements are around immovable apparatuses (pommel horse,
rings, parallel bars and high bar) for the extended period of time. Since there
are not so many studies that have dealt with this topic and on actual
competition, we have aimed to examine the handgrip strength influence on the
competition result in elite male artistic gymnasts. The sample of participants
were conducted of 37 elite male artistic gymnasts (8–21 years old), from 8
different countries as national team competitors at the International Competition
“Laza Krstić and Marica Dželatović” held in Novi Sad, Serbia. Basic
anthropometric measurements were included (body height, body weight and Body Mass
Index (BMI)), along with training experience and handgrip strength measurement
(both dominant and nondominant hand). Kolmogorov-Smirnov Z test (p <
0.05) was used for distribution normality, along with regression analysis with
Model 1 (participants age, training experience, body height, body weight and
BMI), Model 2 (Model 1 + dominant handgrip strength) and Model 3 (Model 1 +
nondominant handgrip strength). SPSS v.20 was used for all statistical analysis.
Our study have revealed that there is significant influence of all 3 Models on
the parallel bars final result (p = 0.033; p = 0.049; p
= 0.031, respectively), in terms of all set of variables, whereas body weight Beta
scores (28.6%; 30.3%; 32.7%, respectively) moslty explains the results. Both
dominant and nondominant handgrip strength are influential factors only on the
parallel bars final result. Since both hands are contributing equally, bilateral
training is necessary. In order to expand the knowledge on this topic and
completely understand the influential factors, future studies are needed on this
sample. Regardless of our main findings, our results should be taken with
caution
