Investigation of acute effects of different warm up protocols, on 30 M. speed, flexibility, vertical jump, strength, balance and anaerobic power performances in judokas

Aim: The aim of this study is to investigate acute effects of different warm-up protocols, on 30 m. speed, flexibility, vertical jump, strength, balance and anaerobic power performances in judokas. Material and Method: Twenty healthy male active judokas who at the ages of 11-14, from İzmir Metropolitan Municipal and Manisa Sport clubs, exercising three or five times in a week voluntarily attended to this research. This study is available just one group in which was included 20 people and there isn't any control group. Four different warm up protocols which have been applied with content for 48 hours. Twenty participants into four equal warm up protocols were randomly taken to exclude the learning effect and the cumulative effect. This study consist of four different warm up protocols; warm up application-1; only low density aerobic run (without static stretch or dynamic type exercise), warm up application-2; low density aerobic run and then static stretching, warm up application-3; low density aerobic run and then dynamic type exercises, warm up application-4; both static stretch and dynamic type exercise were consisted after low density aerobic run (jogging). After each warm up application, 30 m. speed, flexibility, vertical jump, strength, balance and anaerobic power performances of research group were measured. Prior to two days from the first warm up protocol application , all judokas were instructed about warm up protocols and tests then were tested warm up protocols once. Every warm up applications started with 5 minutes low intensity (jogging) aerobic runs to their own protocol day. Judokas rested walking with 2 minute after 5 minutes run were completed. After a relaxing walk application, planned warm up methods of all other warm up protocols were held except to the first warm-up practice. The end of each warm up application were given 4-5 minutes of rest and then 30 m. speed, flexibility, vertical jump, strength, balance and anaerobic power tests were performed. Stations were set to measure every parameter except to 30 m. speed on the judo mats and one researcher was charged with a station. After one measurement, judokas passed to other measurement station. Arithmetic mean and standard deviation were used for data numerical presentation. Compatibility of the data to normal distribution guess was carried out with Shapiro-Wilks test. Repeated four different measures of normal distribution data was used Repeated Measures of ANOVA and difference due to which measure to find out were used LSD measurement of the post-hoc tests. Repeated four different measure of nonparametric was performed Friedman test and difference due to which measure to find out was applied dual pairing made to the Wilcoxon test. SPSS 18.0 statistic program (SPSS Inc, Chicago, IL) is used in data analyses and p<0.05 is accepted as statistics significance level. Results: When 30 m. speed values are investigated, among four different warm up protocols, p<0.05 level difference is found between warm up application-1 and warm up application-4, p<0.05 level difference is found between warm up application-2 and warm up application-3, p<0.001 level significant difference is found between warm up application-2 and warm up application-4. When flexibility measurement values were investigated, among 4 different warm up groups, no significant difference is found (p>0.05). When we compare between flexibility applications, only between warm up application-1 and warm up application-2, p<0.05 level significant difference is found. No significant difference is found between leg strength performance (p>0.05). When we compare the applications of leg strength performance, p<0.01 level significant difference is found between warm up application-1 and warm up application-4 group and p<0.05 level significant difference is found between warm up application-2 and warm up application-4 group. No significant difference is found on vertical jump, balance and back strength performance. Conclusion: According to investigation results; after both static and dynamic exercise done with judokas, 30 m. performances is observed better. After static exercise, flexibility performances of sportsmen are observed better. When leg strength values were investigated, strength drafts are observed higher after static-dynamic exercise. Consequently; 11-14 aged male judokas, static and dynamic exercises are required to be carried out together for high strength performance improvements such as 30 m. speed performance and leg strength before training and consent. And it is suggested that static exercises are required for developing flexibility performance.
