Akuta effekter av assisterade hopp på kvinnliga idrottares hoppförmåga

Vertical jumping ability is an essential skill in many sports. The aim of this study wasto investigate the acute effects of assisted Jumps on subsequent countermovementjump (CMJ) performance by female athletes. Nine healthy, trained female subjectsvolunteered to participate in the study. In a randomized order, they performed oneregular warm up protocol before testing their CMJ baseline value, and one warm upprotocol with an addition of five assisted Jumps at 30% body weight reduction beforeanother CMJ test. Elastic cords attached to an overhead pulley system and to aharness around the subjects' upper body were used to reduce the body weight.Significant improvements were noted in jump height, 2.3 cm (7%), positive forceimpulse, 4.7 Ns (2%), vertical take off velocity, 0.1 m/s (3%), countermovement time,0.1 s (12%) and breaking time, 0.1 s (14%), p.

Postaktiveringspotentiering i knäböj med hjälp av countermovement jumps

Studien avser att studera effekterna av arbetsplatsförlagd fysisk träning 2 x 60 minuter/vecka i 7 veckor hos personer med stillasittande arbete påVO2max, rörlighet, uthållighetsstyrka och kroppssammansättning. Vi använder oss av en kvantitativ metod som består av datainsamling genom tester före och efter träningsperioden för både interventionsgruppen (n=25) och kontrollgruppen (n=11). Resultaten visar på signifikanta skillnader hos interventionsgruppen på variablerna VO2max (p=0), visceralt fett (p=0,001), fettmassa (p=0,001), vikt (p=0.006), Body Mass Index, BMI (p=0,005), uthållighetsstyrka enligt Sörensens isometriska uthållighetstest (SIU) (p=0) och Trunk Curl Static Endurance test (TCST) (p=0,045), rörlighet i halsrygg (p=0,010) och rörlighet i hamstringsmuskulatur via Sit and reach test (p=0).  Inga skillnader ses i blodtryck och, skelettmuskelmassa i armar, bål och ben. Inga signifikanta skillnader ses hos kontrollgruppen oavsett variabel. Slutsatser av studien är att man kan se effekter genom denna typ av intervention på flera olika variabler och förslag till framtida forskning är att försöka utesluta samverkan av andra faktorer för att ge en mer exakt bild av den fysiska träningens effekter på arbetsplatsförlagd träning..

Effekten av betainsupplementering på prestationsförmågan hos vältränade cykelatleter

Bakgrund: Syftet med denna studie var att undersöka effekten av sju dagars tillskott av betain (2,5 gram/dag) på prestationsförmågan i idrottsspecifika tester för manliga vältränade cykelatleter.Metod: Sex (n=6) manliga testpersoner (genomsnitt ± standardavvikelse ålder, 31,7 ± 10,2 år; längd, 188,2 ± 3,6 cm; kroppsvikt; 82,5 ± 7,6 kg; fettfri massa, 71,6 ± 7,3 kg) genomförde förtester bestående av fem counter movement Jumps, fyra stycken 12 s wingate-sprinter med 2,5 minuters aktiv vila följt av fem ytterligare counter movement Jumps. De blev sedan indelade slumpmässigt i betain- eller placebogrupper. Första testet etablerade basvärden och eftertest ?1? samt ?2? föregicks med antingen sju dagars tillskott med placebo (2,5 g maltodextrin plus 12,5 mg riboflavin) eller betain (2,5 g trimetylglycin plus 12,5 mg riboflavin). Riboflavin användes för att undanröja den fiskliknande doften som kan uppstå vid tillskott av betain.

Off-ice vs. on-ice : Hopptesters samband med skridskoåkning i ishockey

AimThe purpose of this study was to investigate the relationship between off-ice horizontal jump tests and on-ice skating among students at hockey high schools. Questions: What is the association between the performance on horizontal Jumps and skating 10 meters standing start among students in Swedish ice hockey high schools? What is the association between the performance on horizontal Jumps and skating 10 meters flying start among students in Swedish ice hockey high schools?MethodStudents at three ice hockey high schools in the Stockholm area participated in the study. Two schools were national approved sports educations and one at lower level. All 50 students (41 at national approved sports educations and 9 lower level) that were included in the study were men and went year one and two in gymnasium.

Utveckling i Java av ett pedagogiskt spel i kvantfysik

The game QuantoJump is developed in the programming language Java to be an educational game in quantum physics. By illustrating quantum mechanical laws of electron transitions with shapes and colours, QuantoJump hopes to spark interest and create a more intuitive understanding of quantum physics. The result is a game where the player plays as an electron in the outermost shell of an atom, with the goal of getting to the innermost shell. This while not making forbidden Jumps by following the laws of electron transitions dictated by quantum physics. The programming of the game was done in the integrated develpoment environment Eclipse.

Den paradoxala internkommunikationen : En studie om den interna förändringskommunikationens roll i ett gasellföretag

For some time researcher has focused their interest on how women are being treated in sports and what impact it has on the development of the sports movement. Researchers in the field have tried to clarify where the problem lies, if it is gender or sex. Are the differences between the sexes caused by how society portrays women or because women and men are built for different purposes. This research paper studied how women in the sports of snowboarding and freeskiing perceived their possibilities to practice their own sports. Furthermore, the study tried to answer if the problems are originated from the culture of the sports, what the possibilities and opportunities women had to make ?it? and what women think is the reason why there are so few female athletes in their sports.

Finns det någon variation i CMJ som återföljs av förändringar i någon av pulsvariationerna och handstyrkan?

IntroductionSuccessful training is a key for athletes to make progress in their development. Training must not just involve overload, but also must prevent the combination of excessive overload plus inadequate recovery. Athletes can experience short-term performance decrement without severe psychological or lasting other negative symptoms. Too much hard exercise or too little sleep can cause overtraining, a condition in which the subject can prevent to be away from the sport for several weeks or months. Previous studies have detected that it is important to avoid overtraining.

USA:s syn på Turkiet, från 1997 fram till våren 2007

The aim of this essay is to analyze the political interests of the United States Government in Turkey, from 1997 to spring 2007, using a qualitative method. I will also analyze any strategic changes during this period, by using theories of realism, particularly Structure Realism and Rational Choice. Using the Rational Actor Model (RAM), I will analyze how nation states such as the United States act in the political arena in Turkey. How can the US Government legitimize the support to Turkey and at the same time criticize there democratic deficit and their view on human rights. Turkey has been an American Military Ally, via NATO since 1952 and its demographic situation has changed since the Cold War.

En studie av sex ISA-system

On a request from the water sewage plant Gryaab in Gothenburg a power quality survey was performed. The voltages and currents have continuously been sampled in the incoming 10 kV substation HSP01 from April-August 2008. Power quality measurements were also performed in Gryaabs other 10 kV substation HSP04 fed from HSP01 and at the terminals of the induction motor IN_PU4040 of 1.3 MW which controls one of the four large inflow pumps to the plant. The reason for the latter measurement was due to registered negative transients each time the motor was connected to the grid. The cause of the transients could be explained by the coupling in the substation, the ageing of the motor which could result in damage of the bearings or resonance in the motor circuit which amplifies high frequency harmonics.

Djuromvårdnad vid fång, bärrandsröta och spiktramp hos häst

60 million years ago the horse was the size of a small dog, and walked on four toes. Today it can weigh up to 500-1000 kg and has evolved to walking on only one phalanx. The anatomy of the horses? legs and hooves allow them to run at high speeds, and at the same time enables them to bear the extremely high concussions applied to the foot at high speeds or Jumps. Every horse owner has his or her own opinion on how to manage their horses? hooves, and whether the horse should be shod or unshod. The knowledge, commitment and attention of the owner determine the quality of the hoof care, but also the time between the arising of symptoms of abnormalities of the hoof until care is sought with a farrier or veterinarian. New laws will be applied at the beginning of 2015 which bring on changes in authorization for farriers.
