Boxers ability to punch at predetermined punching intensities (English)
Abstract [sv]

SyfteStudiens syfte är att undersöka boxares förmåga att slå slag med givna intensitetsnivåer mot en boxningssäck. Vidare syftar studien till att undersöka boxares förmåga att hålla en förbestämd submaximal intensitsnivå vid sparring.MetodFyra boxare deltog i studien. Corner handledssensorer användes för datainsamling av slaghastighet och acceleration i slag under slagtest på säck i självvald 50 %, 70 %, 90 % och 100 % intensitet, och i två 3-minutersronder av lätt sparring med instruktionen att sparras i 50 % intensitet. Shapiro-Wilks test användes för att undersöka variablernas normalfördelning, därefter analyserades data med One-sample t-test och Wilcoxon Signed-rank test beroende på normalfördelningen.ResultatDet fanns signifikanta skillnader (p < 0,05) mellan flera av deltagarnas slag och slagteknikernas respektive uträknade slagintensitet i samtliga slagintensiteter. Det förekom ingen eskalering (alla p > 0,05) under lätt sparringen, men merparten slagen var över den instruerade sparringsintensiteten (50 %), och i flera fall även över boxarnas maximala slagintensitestvärden.SlutsatserDeltagarna tenderar att underskatta sin egen slagintensitet vid slag mot säck. Vidare så kan det under lätt sparring förekomma flertalet slag med intensitet vid eller över deltagarnas egna maximala slagintensitetsvärden. Resultatet från den nuvarande studien kan dock inte generaliseras på grund av ett litet urval och utrustning utan validering. Mer forskning bör genomföras med ett större urval och även med högre sparringsintensiteter för att se om slagen i de olika intensiteterna skiljer sig åt.

Abstract [en]

PurposeThe purpose of the study was to examine the ability of boxers to punch in predetermined submaximal intensities. Furthermore, the study aims to investigate the ability of boxers to maintain a predetermined submaximal intensity during sparring.MethodsFour boxers participated the study. Corner wrist sensors was used for data collection for punching tests in self-selected 50 %, 70 %, 90 % and maximal effort on a boxing bag, and for punches thrown during two 3-minute rounds of low intensity sparring with the instruction to spar at 50 % intensity. Shapiro-Wilks test was performed to examine the variables normal distribution. The data was then analyzed with One-Samples t-test or Wilcoxon Signed-rank test depending on the normal distribution.ResultsThere were significant differences (p < 0,05) between several of the participants punches and the punching techniques respective calculated punch intensity for each boxer, in all punching intensities. No escalation of punching intensity was found in the sparring rounds, most punches was over the instructed intensity (50 %), and in several cases had intensity values near or even over the participants maximal effort punching values.ConclusionsThe participants tend to underestimate their punching intensity when punching a boxing bag. The results of the present study show that high intensity punches are still present even in light sparring, with several punches having values near or even above the boxers respective maximal punching effort value. However, these results cannot be applied to the general population because of the limited sample size and due to not validated equipment. More research with a larger sample size and including higher sparring intensities for comparison.
