Fysiologiska kvaliteter hos manliga tävlingscyklister och effekten av högintensiv intervallträning

Abstract Road cycling is well established and has always been described as a highly endurance sport. To be able to compete in such a demanding sport the physiology of the athletes needs to be greatly developed. This review will focus on High intensity interval training and its impact on the physiological characteristics of competitive road cyclists. The main difference between different levels of competitive road cyclists seems to be the capacity to maintain a high sub maximal power output over a long period of time in order to succeed. High intensity interval training, from 30 seconds to 5 minutes, leads to improved VO2peak, aerobic peak power and time trial performance.

Sjuksköterskans erfarenheter av mötet med patienter med ett annat modersmål : - En litteraturöversikt

Background: Running economy is one of the key factors to achieve top performance in endurance events. Little evidence exists for improving running economy using high-intensity interval training while running. Objectives: The purpose of this study was to examine how HIIT affects running economy and VO2max. Method: 14 well-trained athletes (age 35 ± 8,9 years, height 175 ± 11,7 cm and weight 69 ± 12,2 kg) were divided into two separate groups (HIIT and Control). HIIT group performed 3 HIIT exercises every week for 4 weeks and Control group continued with their separate training programs consisting of mostly traditional endurance training. Results: Running economy showed no improvement in HIIT (pre 38,62 and post 38,62 ml/kg/min, p=1.00) but Control improved (pre 45,41 and post 43,37 ml/kg/min, p=0,03). VO2max decreased in HIIT (mean 61,32 to 60,84 ml/kg/min) and in Control (mean 61,99 to 58,47 ml/kg/min)..

Diabetes hos hund : utfodring, motion och vikt som möjliga predisponerande faktorer

This is a study of some risk factors for Diabetes Mellitus (DM) in dogs. As a pilot study it is meant to give information to be used in a planned later, larger and better controlled study. The present study hypothesized that suboptimal feeding (high percentage of homemade and table foods), lack of activity and overweight contribute to the risk of DM. Twenty consecutive dogs diagnosed with DM at the Veterinary University Clinic in Uppsala between 2000 ? 2003 were chosen as the experimental group.

Effekterna av praktisk ocklusionsträning periodiserat med ett traditionellt styrketräningsprogram på anaerob prestation

Background: Practical blood flow restriction (pBFR) combined with resistance training has been proven to facilitate muscle strength despite training at low intensity. However, research investigating the effects of long-term pBFR-training and its periodization with strength training (ST) at a higher intensity is lacking, as well as the effects of occlusion training on blood lactate levels (BLL) over time.Purpose: To compare the effects of 2 weeks of pBFR training followed by 2 weeks of ST (BFR-ST) with 2 weeks of ST followed by 2 weeks of pBFR training (ST-BFR) on anaerobic performace and BLL.Method: 5 adults (age 23 ± 2 years) with a minimum of 1 year of ST experience were recruited and randomized into BFR-ST (n=2) or ST-BFR (n=3). Anaerobic performance was measured using a 30-s Wingate-test and BLL samples were collected <1 and 5 minutes post-Wingate. Data and samples were collected before the intervention and after the 2 protocols.Results: No differences were seen between groups in anaerobic output or BLL after 4 weeks of training (p>0,1 for all values). A decrease in time to peak power (tPP) were seen in both groups with an advantage for BFR-ST (-37 ± 8 %) over ST-BFR (-27 ± 22 %).

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.

Hetare med HIIT eller lite mer av LIT?

Bakgrund: Högintensiv intervall träning (HIIT) har i tidigare studier visat sig vara mer effektiv för att öka den maximala syreupptagningsförmågan (VO2Max) än lågintensivträning. Det finns få studier som undersökt sådana anaeroba intervaller som kombinerar maximal sprintning med efterföljande högfart och slutligen gång i normal takt. Syftet med denna studie är därför att undersöka vilken av löpningsmetoderna högintensiv intervall träning och lågintensiv träning ger mest ökad maximal syreupptagningsförmåga samt bäst aerob och anaerob prestationsförbättring.Metod: 9 män och kvinnor valde att frivilligt delta i studien och delades in i antingen en högintensiv eller lågintensiv grupp. Testerna bestod av ett Åstrandtest, 2,5 km löpning och 30m sprint. HIIT gruppens intervaller kallades 20:55:20 då deltagarna först sprang 20 sekunder maximal fart, sedan 55 sekunder i hög fart för att slutligen gå i 20 sekunder.

Skadeförebyggande träning inom elitdamfotbollen : Tränarnas fokus på att förebygga en främre korsbandsskada

This quality study was carried out with seven semi-structured interviews and five of them were with elite women´s football coaches. What has been studied is how elite women?s football coaches are working with injury prevention training to their knees for the women?s football players. An anterior cruciate ligament injury in elite women?s football is both common and serious knee injury.

Jämförelse av effekter från gruppträning i bassäng med landträning hos patienter med knäartros : Utvärdering av effekter på smärta, funktion i det dagliga livet och fritid- och idrottsaktiviteter

AbstractAimThe aim of the pilot study was to compare short- and long-term effects from group exercise in water with land-based exercise on pain at rest and pain with movement, along with the effects on function in daily life and practice of sports and leisure activities in patients with knee osteoarthritis. The aims were: Is there a difference in short- and long-term effects on pain intensity at rest and pain with movement after exercise in water or land in patients with knee osteoarthritis? Is there a correlation between the degree of pain intensity at rest and with movement, respectively and long-term effects from the two different exercises on function in daily life and practice of sports and leisure? MethodThe study was a randomized intervention study without a control group. Twenty patients with radiographic knee osteoarthritis were under a total of eight weeks treated with either land- or water-based exercise lead by a physiotherapist. The patients rated pain intensity at rest and with movement on a numerical rating scale (NRS) before and after the first training session, before and after the eighth training session, before and after the fifteenth training session and before the last and sixteenth training session.

Med och utan hemträning ? en utvärdering av hörförståelseträning vid afasi

Previous studies shows that high-intensity aphasia interventiongives better results than intervention that is less intense. This study evaluateda working model at a hospital in Gothenburg which involve related personsin intervention. The model prescribes daily training in the home. The caseseries design study investigated the effect of intervention on auditorycomprehension, impact on participation and examined how the relatedperson judged that communication was affected. Four participants withsevere aphasia received intervention for 16 weeks, 8 of which includedintensive training at home and at the clinic, while 8 weeks only includedclinical intervention.

The effect of social rank on milking and feeding behaviour in automatic milking system for dairy cows

Today automatic milking systems (AMS) are growing in popularity. In these systems the cows are loose and have to get to the robot and the feed on their own. The cows ranking in this system affect their welfare. In this study data from seven years in an AMS was used and analysed. The aim was to investigate how ranking could affect the behaviour of the cows at milking and at feeding.

Genetisk variation i brunststyrka hos svenska mjölkkor :

When cows in Sweden are inseminated the heat strength is reported to the Swedish milk-recording scheme and AI scheme. Cows that show strong signs of estrus are desirable and the trait is included in the Swedish breeding goal. A strong heat makes it easier to inseminate at the right time and to avoid long and expensive days open. Since ten years the heat strength is scored from one to five by the farmer and reported to the milk-recording scheme and AI scheme. Earlier the score was from one to three and the decision was made by the AI technician.

Effekt av utfodring och motion för utveckling av diabetes mellitus hos gråhund och jämthund. :

This study is a follow up of a pilot study made 2004, that evaluated feeding, exercise and weight as possible risk factors for developing any kind of diabetes in dogs. We have selected our material for a certain kind of DM that exists among Norwegian and Swedish elkhounds. These breeds are among the most common breeds affected by diabetes and this kind of DM almost exclusively affects intact bitches. We performed a case- control study where the owners were interviewed over the phone. The owners of a total of 48 case dogs and 58 control dogs were contacted. The questions for the cases focused on the time before the diagnosis and the questions for the control dogs focused on the dog´s adult life.

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.
