Abstract [sv]

Förmågan att generera kraft kan korrelera med individens prestationsförmåga i idrotter, sprint- och hoppträning kan gynna prestationsförmågan inom vissa idrotter. Syftet med denna studie var att undersöka huruvida det fanns korrelation mellan prestation i 5RM knäböj med skivstång och enbenslängdhopp. Vidare undersöktes även hur 5RM relaterat till kroppsvikt påverkade hopplängd, skillnader mellan män och kvinnor och skillnad i hopplängd mellan dominant och ickedominant ben. Totalt 37 motionärer rekryterades, 15 kvinnor och 22 män (35 ± 11 år), alla var erfarna av knäböj med skivstång. Deltagarna fick efter uppvärmning utföra en maxprestation i horisontella enbenshopp, vila 8 minuter och hitta sitt 5 RM i knäböj. Resultatet visade på svag positiv, statistiskt signifikant korrelation mellan hopplängd och muskelstyrka mätt i 5 RM knäböj (r= 0,4 p<0,05), samt svag icke signifikant korrelation (r= 0,21, p>0,05) då hänsyn till kroppsvikt togs.  Män hoppade 310,2 ± 39,6 cm vilket var signifikant (p<0,05) längre än kvinnor som hoppade 266,3 ± 47,3 cm, mellan dominant och ickedominant ben visades ingen signifikant skillnad i hopplängd. Resultaten visade på ett signifikant svagt samband mellan 5 RM knäböjtest och enbenstest för hoppförmåga. Resultaten kan tolkas som att testen mäter olika fysiska förmågor dock har muskelstyrkan betydande inverkan på hoppförmågan.

Abstract [en]

The performance in sports may be determined by the ability to generate power. Sprinting and jumping in training can be beneficial to the athletes´ ability to perform explosive type of sports. The aim of this study was to examine the relationship between single leg hop for distance and a) back squat strength, 5 Repetition Maximum and b) back squat 5 Repetition Maximum correlated to body weight. A secondary aim was to examine the hop performance of dominant and non-dominant leg between males and females. 37 recreational individuals participated in the study, 15 women and 22 men (35 ±11years), all subjects were used to squatting. After warm up, the subjects were told to make a single leg hop for max distance, (3 tries) rest 8 minutes before squatting up to a 5 RM back squat.  The results showed that there was a positive correlation between total jump length (right + left leg) and 5 RM max weight (r= 0,4 p<0,05) and a significant difference in total jump length between males and females (p<0,05) but no difference in jump length between dominant and non-dominant leg between the subjects. Participants´ familiarity of jumping activities may have influence the outcome of this study.
