Hur påverkas muskelaktiviteten vid styrketräning med en tjock stång i jämförelse med en standardolympisk stång? : En EMG- studie
Many everyday tasks and also many sports require good grip and forearm strength. Everything from carrying boxes and lifting a child to grab the arms and legs in various martial arts, or holding a tennis racket involving the hand and forearm muscles in various ways. It is therefore important to train these muscles to prevent injuries and congestion and to perform well in sport. A well known way to train functional strength in the hand and forearm muscles is weight training with thick handles. The purpose of this study was to investigate the differences in muscle activity in the upper arm and forearm muscles as well as the deltoids between two bars of different diameter (28mm and 57mm) in two different weight training exercises using electromyography (EMG).
Faktorer av betydelse för styrkeutvecklingen i nedre extremitet vid kombinerade uthållighet- och styrketräningsprogram: En beskrivande litteraturöversikt
Vissa studier som undersökt kombinerad styrketräning och uthållighetsträningjämfört med styrketräning har funnit hämmad styrkeutveckling vid kombinerad träning.

Syftet med litteraturöversikten var att genom att granska vetenskaplig litteratur i området beskriva faktorer av betydelse för styrkeutvecklingen i nedre extremitet vid kombinerade uthållighetoch styrketräningsprogram. En beskrivande litteraturstudie gjordes på ämnet. En litteratursökning genomfördes mellan 6-24/9, 2014 i databaserna Scopus, Proquest, Pubmed, Cinahl, AMED, Web Of Sciense.
Alkoholintag efter träning och dess inverkan på muskeluppbyggnad och återhämtning hos vuxna män - En systematisk litteraturöversikt
Sahlgrenska Academyat University of GothenburgDepartment of Internal Medicine and Clinical NutritionAbstractTitle: Alcohol consumption after training and its effects on muscle gain and recovery adult menAuthor: Frida Carlstedt, Puck JanssonSupervisor: Frode SlindeExaminer: Anna WinkvistProgramme: Dietician study programme, 180/240 ECTSType of paper: Examination paper, 15 hpDate: April 09, 2014Background: Today, the Swedish population exceeds the recommendations for alcohol intake while advised to move at least thirty minutes a day. It is well established what happens if you drink alcohol before a workout or if you workout the day after an alcohol intake, but it is less well established how muscle gain and recovery are affected by an intake of alcohol in the phase of recovery.Objective: The objective of this review is to investigate if there is a relation between alcohol intake after a workout and effected recovery and muscle gain. This was performed by measuring the outcomes cortisol, testosterone, creatine kinase as well as different measures of muscle strength. The issue was ?Does an intake of alcohol after training affect recovery and muscle gain??Search strategy: A systematic review in the databases PubMed and Scopus with the MeSH-terms: exercise, muscles, recovery of function, training, athletic performance, performance, sport, alcohol drinking, alcohols, alcohol and ethanol.Selection criteria: Criteria for articles to be included in this review were that they would be RCT- and human studies in healthy subjects as well as containing an ethanol intake after a physical activity that consisted of weight training in the form of resistance training or other forms of activity that promotes strength.Data collection and analysis: A systematic search for literature as mentioned above (search strategy) was performed as well as an analysis with the SBU quality review template for randomized studies, and a quality review for each measure of outcome according to Gothenburg University summarized evidence template for measures of outcome.4Main results: Many studies are authored by the same group of researchers and/or are of a lower quality.
Styrketillväxt med hjälp av vibrationsplatta
Abstract 1.The purpose of this study was to investigate the effects whole body vibrations on maximal strength, power output and neuromuscular activity in m. pectoralis major during bench press.Participants consisted of 35 male and 9 female military high school students (m=23, 1 years). On the basis of initial maximal performances in bench press the participants was divided into two experiments groups and one control group. Intervention groups performed a specifically designed push up program on a vibrating plate respectively a step board during 12 weeks Initial load at 60 % of 1 RM showed an average of 46, 5 kg. All groups showed an average increase of 13 kg for each person after 12 weeks.
Sömn och Powernap - Dess betydelse för återhämtning och prestation
During sleep the majority of the body?s production of anabolic hormones is produced and sleep is a general anabolic state of being. It has been to our recognition that a powernap is 4-6 times more effective when it comes to sleep intensity than the last 1-2 hours of a traditional eight hour sleep. With this in mind, and that elite athletes worldwide often sleeps in between their training sessions. This study has tried to prove a hypothesis which comes from the assumption that you can recover and perform better during times with intensive periods with better distribution of your sleep.We have in this study let three test subjects take part of a six week long program with two different training periods for legs.
Effekter av funktionell träning och medicinbollkast för att optimera kinematic sequence och x-factor stretch i golfsvingen
The interest for functional strength training in golf has grown the last decade and scientists are always trying to find training stategies to improve the biomechanical aspects of the swing. Kinematic sequence contains a proximal-to-distal sequence order towards impact, and an effective kinematic sequence in the down swing begins with a rotation in the pelvis and follows by an activation in thorax, arms and club in the respective order. The rotational torques in the proximal segments wanders through the body and to the more distal segments to create an effective energy ? and power transfer at impact. The x-factor stretch is the seperation between the rotation in the pelvis and the thorax at the top of the back swing and at the beginning of the down swing.
Galoppträning och körning med två travare
The aim of this study was to evaluate whether gallop training, rather than regular drive training, is worthwhile for trotters race performance. Another aim of the study was to expand the author?s riding- and driving capacity, and get more practical experience on the impact of interval training on trotters. The sample population in the study was two trotters, one Standardbred, and one cold-blood. Given the small sample population, the results of the study is only indicative on the effects of gallop training on trotters, and not conclusive.
Fotbollsledare om styrketräning för barn : ? når forskning ut?
Fysisk träning för barn har alltid varit ett kontroversiellt ämne som berör såväl etiska och fysiologiska som medicinska frågor. Styrketräning är den form av träning som ställer dessa frågor på sin spets. De svenska officiella organen Idrottens Forskningsråd (IFR) och Riksidrottsförbundet (RF) har genom åren lagt fram rekommendationer och riktlinjer som ska fungera som underlag vid utformning av den träningsverksamhet som bedrivs i idrottens föreningsliv. Eftersom forskningsrön har förändrats i takt med forskningsframsteg har också rekommendationer och riktlinjer från officiellt håll varierat över tid. Syftet med föreliggande studie var att undersöka om fotbollsledare har kännedom om de senaste rekommendationerna vad gäller styrketräning för barn.

An anterior cruciate ligament injury in elite women?s football is both common and serious knee injury.
Training techniques used in training horses (Equus caballus) : with a focus on positive reinforcement
Instrumental conditioning, the use of reinforcement and punishment, is used when training horses and these procedures may have different consequences regarding animal welfare. The aim of this study was to investigate what kind of reinforcers that are used in training horses and when these reinforcers are used. This study has its focus on positive reinforcement and its advantages and disadvantages. Interviews of five A-level and B -level equestrian coaches about their training methods were conducted to complement the literature search and give a greater understanding to why certain methods are used or not in training horses. The results show that negative reinforcement seems to be the foundation of training horses whereas positive reinforcement is used but not to the same extent.
Effektutveckling i den koncentriska fasen i bänkpress och knäböj
Aim: The aim of the study was to investigate 1RM and what power could be generated in bench-press and half squat concentric at certain percentages of 1RM. Special interest was put to evaluate men (M) and women (K), strength trained (ST) verses non strength trained (EST) in generating absolute power as well as power relative to 1RM.Method: In total 59 subjects mean (± SD) age 24.9 ± 4.1 years divided into four test groups: 20 male non strength trained GIH-students (EST M), 20 female non strength trained GIH-students (EST K), 10 male strength trained - sprinters on national/regional level (ST M), 10 female strength trained - sprinters (ST K) on national/regional level. They did two tests on 1RM and power in events of concentric bench-press and half squat in a Smith machine. In the first test session 3 ? 5 lifts were made to measure 1RM in each event.
Effekter av 20 minutrs daglig fysisk träning av kondition, styrka, rörlighet och balans. : En 10 veckors interventionsstudie av kvinnliga lokalvårdare
Public health focuses on interventions related to physical activity during leisure and at work under conditions where health care is offered during working hours. Increased physical activity offers many positive effects on health in general and reduces the risk for most injuries and illnesses. Female cleaners represent a profession that is largely composed of women at high risk of overload injury and rarely participate in wellness initiatives offered at workplace. The purpose of this study was to investigate the effects of 20 minutes of daily physical exercise for 10 weeks of intervention for healthy female cleaners. A total of 40 female cleaners in a larger organization participated in the study and were divided in into an intervention group and a control group.

The study included all the managers in 37 pediatric wards whoparticipated in telephone interviews with the aid of a questionnaire. The results showed that81 % of the Swedish hospitals that have a paediatric ward train the staff in neonatal lifesupport. All of the university hospitals and 74 % of the other hospitals are running training insome form. The methods of training varied and so did the occurrence of training.
Vibrationsträning vid knäledsartros
In cooperation with Hälsoteamet Halmstad a pilot study was made to see if whole body vibration exercise has any effect on muscle strength, movement and experience of pain in people with knee osteoarthritis. Today whole body vibration exercise is a revolutionary exercise method that needs more studies to show the positive and negative effects. Osteoarthritis is a degenerative disease where more cartilage is destroyed than replaced. The most common symptoms are pain, stiffness, restricted movement, muscularly atrophy, tenderness and instability. The cartilage needs pressure to rebuild, it is therefore important that the patient exercise.
