  1. 1. Improved Transformer Duality Model for Geomagnetically Induced Currents

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Martin Karlsson; [2018]
    Keywords : ;

    Abstract : A lumped element transformer tank model has been developed for evaluating the power dis-sipation in the tank and flux distribution in the transformer when it is subjected to a DC current in the neutral. FEM simulations are performed to assist in developing a per-phase magnetically separated transformer tank model that takes into account currents induced in the tank. READ MORE

  2. 2. Very Heavy Resisted Sprint Training for Adolescent Football Players : A training intervention on acceleration, sprint and jump performance in late pubertal adolescent athletes

    University essay from Gymnastik- och idrottshögskolan, GIH/Institutionen för idrotts- och hälsovetenskap

    Author : Mikael Derakhti; [2018]
    Keywords : Resisted sprint training; Very heavy resisted sprint training; Sprint training; Speed; Power; Youth football; Youth Soccer; Football; Soccer; Specific resistance training; Biological age; mid-PHV; post-PHV; PAH; Belastad sprintträning; Väldigt tungt belastad sprintträning; Sprintträning; Snabbhet; Effektutveckling; Fotboll; Ungdomsfotboll; Specifik styrketräning; Biologisk ålder;

    Abstract : Abstract Aim The main purpose of this study was to investigate and compare the effects of a very heavy resisted sprint training regimen and a unresisted sprint training regimen on sprint, acceleration and jump performance in late pubertal adolescent football (soccer) players at mid- to post-PHV and >95% PAH. Method In total 27 male football players were recruited as volunteer participants. READ MORE

  3. 3. Validation study of a portable accelerometer to measure muscular power output : Correlation between the Beast Sensor and the linear encoder MuscleLab

    University essay from Högskolan i Halmstad/Akademin för ekonomi, teknik och naturvetenskap

    Author : Jonas Bergenblad; [2017]
    Keywords : power; beast sensor; musclelab; squat; bench press; linear encoder; linear position transducer; accelerometer; training;

    Abstract : Abstract Background: The ability to produce a high power output can be the deciding factor in determining which athlete wins or loses in a sporting event. Power output can be measured in an exercise like the squat or bench press. READ MORE

  4. 4. The effect of a weight lifting belt and the use of valsalva maneuver on power output and velocity in a squat

    University essay from Högskolan i Halmstad/Akademin för ekonomi, teknik och naturvetenskap

    Author : Julia Björk; [2017]
    Keywords : Linear encoder; power output; squat; strength training; valsalva maneuver; velocity; weight lifting belt; Effektutveckling; hastighet; knäböj; linear encoder; lyftarbälte; styrketräning; valsalvamanövern;

    Abstract : Background: A squat is a common exercise that is used in many areas of strength training and for different purposes and the literature is inconclusive when it comes to whether the weight lifting belt (WB) affects performance and/or is injury-preventing. The use of breathing techniques is common during heavy lifting and therefore the practice of the breathing teqnice; valsalva maneuver (VM) may be of interest to study and if this along with the WB can provide some advantages in power output and velocity.

  5. 5. “The development of a new reactive agility test for soccer”

    University essay from Mittuniversitetet/Avdelningen för hälsovetenskap

    Author : Erik Åslin; [2017]
    Keywords : explosivitet; reliabilitet; snabbhet; styrka; validitet.;

    Abstract : Fotboll är en intermittent sport med både offensiva och defensiva aktioner som kräver ett flertal höghastighetsrörelser (sprint, vändningar) som respons till yttre stimuli vilket betonar betydelsen av att träna och testa agility (kvickhet). Syfte med denna studie var att a) konstruera ett nytt fotbollspecifikt reaktivt agility-test, b) utvärdera reliabiliteten och validiteten av de nya testerna och c) undersöka eventuellt samband mellan fysiska egenskaper (snabbhet, effektutveckling/explosivitet, styrka) och snabbhetstest med riktningsförändringar (CODS) och förmåga till reaktiv agility (RA).
