Förändras syreupptagningsförmågan hos kvinnor efter regelbunden stavgång respektive gång utan stavar?

The purpose of this study was to evaluate if there is a difference in maximal Aerobic power (VO2-max) between walking with poles and without poles. Thirty-four healthy women between the ages of 22 and 60 years participated. They were randomised into two groups, seventeen individuals walked with poles and seventeen walked without poles. Both groups walked four kilometres three times a week, for eight weeks. Each completed a submaximal cycle ergometertest before and after the exercise period.

En validitetsstudie på beeptestet : avseende maximal aerob kapacitet för elitishockeyspelare

Introduction: This study aimed to investigate the validity and reliability of the 20m multistage shuttle run test (MST) for elite ice hockey players as a predictor of the maximal Aerobic capacity and the how the result is affected by the players age, Aerobic and anAerobic capacity, body composition and test surface. The purpose of this was to find out the potential of the 20-m shuttle run test as a measuringtool for the maximal Aerobic capacity in frequent testing periods during the season. It is very interesting to be able to administer this easily because the competative phase of the season is very long compared to the pre-seasonal phase and earlier studies have shown that the Aerobic capacity is being lowered during this competative phase of the season for elite icehockey players.Methods: 34 elite ice hockey players participated in this study (20.0±3.6 yrs, BMI 24.2±1.6 and VO2-max 58.0±4.8 ml O2?kg-1?min-1). During 3-5 days they underwent 2 MST tests (wood and rubber surface), treadmill running with VO2-max assessed with open-circuit technique, Wingate10% and FFM-assessment with underwater-technique.

Utvärdering och jämförelse av olika fälttester för fotbollsspelare

Different field tests are currently used in a wide extent in different levels of soccer teams. To be able to assess the players? physiological status the tests must have high validity, reliability and external validity. Many different tests have been developt, but currently only five of these tests are most commonly used: Yo-Yo intermittent recovery test (YIRT), Yo-Yo intermittent endurance test (YIET), Multi-sprint-test, Beep-test and Cooper-test. Presently there is no definitive conclusion regarding which of these tests is most suitable for soccer players.

Detektion av mRNA från en cytokrom c gen belägen i genklustret för kloratmetabolism i Ideonella dechloratans

Abstract:In previous experiments with the bacterium Ideonella dechloratans a probable sequencecoding for a cytochrome c protein (cyt c) was observed, the sequence is assumed to have afunction in the bacterial respiratory chain. Detection attempts have been made to try to findthis protein, but have not succeeded. The purpose of this project is to detect the expressionof mRNA associated with the cytochrome c. And if it is detected, it will also be investigated ifthere is any difference in expression of the mRNA due to Aerobic or anAerobic environment.Total RNA was purified from cultures grown under Aerobic and anAerobic conditions. cDNAwas then synthesized using reverse transcriptase and subsequently amplified with thespecific primers in a qRT-PCR.qRT-PCR testing showed a distinct amplification of primer product, confirming that I.dechloratans expresses mRNA coding for the cyt c protein.

Yeast in forage crops and silage aerobic stability at 15 Swedish dairy farms

This study investigates the role of yeast in green crop and its impact on the Aerobic stability of silage. Fresh crop was collected from 15 farms in southern and middle parts of Sweden during the summer 2014; samples from the primary harvest was collected from eight farms and samples from the first regrowth harvest was collected from seven farms. The grass was ensiled in 1.7 l glass silos. After three months of ensiling, silos were opened and silages were stored Aerobically for 10 days. Samples from both harvests were ensiled in completely airtight silos, but samples from the second harvest were also ensiled in slightly ventilated silos. Chemical analyses and yeast counts were performed for fresh crop and silage.

Fysisk kapacitet hos fysiskt aktiva och inaktiva ungdomar

Background: During the last decade physical activity among Swedish adolescents has decreased. Changes regarding physical fitness can also be seen, for instance the cardio respiratory capacity has decreased mainly among young men while muscular capacity has decreased in both genders. Physical inactivity and impaired physical fitness are both important health related parameters. 18-year olds have fulfilled their physical development and are physically on top of their development, it makes this group interesting to examine. Objective: The aim of this study was to investigate differences between physically active and inactive young men and women, concerning cardio-respiratory fitness, muscular fitness and balance.

Energieffektivisering av luftningssteget på Käppalaverket, Lidingö

This master thesis in energy optimization was made during the autumn of 2006 at Käppala wastewater treatment plant in Lidingö, Stockholm. A preceding thesis, where all electricity consumption was mapped, showed that the aeration in the biological treatment is the single largest consumer in the plant, and it is therefore of interest to reduce this cost. The oxygen control strategy used at Käppala WWTP is working well from a nutrient removal point of view, but not from an economic one. The last Aerobic zones have a very low oxygen consumption during low loading periods which give rise to enhanced dissolved oxygen concentrations with excessive costs and reduced denitrification as a result. But also during periods of normal loading unnecessary high oxygen concentration are sometimes given.By modifying the aeration control strategy three full-scale experiments have been made, with the intention to reduce the air consumption.

Anaerob rening vid StoraEnso Skoghalls Bruk

An analysis of a specific application of anAerobic wastewater treatment at a pulp and board mill, Stora Enso Skoghall, was carried out. A literature study was done and effluent wastewater from CTMP pulp production was analyzed. The analysis consisted of a broad constituent analysis and an anAerobic treatment trial. Results from these test where used to calculate the treatment effectiveness and resulting energy potential at the mill.The literature study and constituent analysis showed that toxicity of the water to be treated, due to wood extractives and sulphur content, was of concern. Detoxification chemicals targeting these constituents where used in the anAerobic treatment trial.

Klostridier och jästsvamp i ensilage ? orsak, verkan och samverkan

Yeast and Clostridia is a problem in silage for farmers as contaminated silage may result in poor animal health and milk quality. Clostridia can produce toxins that, when consumed, acts as neurotoxins, it may also cause blown cheeses if the Clostridia contaminates milk. The purpose of this study was to investigate the cause, effect and interaction of yeasts and Clostridia in silage. Clostridia are microorganisms which are strictly anAerobic and consume carbohydrates and protein in the silage. Yeast is a fungus that is facultative Aerobic and feed on carbohydrates in the silage.

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.

Utvärdering av anaerob behandling av hushållsspillvatten och tekniker för efterbehandling

The continuous process of urbanization results in demands on research and development for ecological and sustainable city development. Because of this, the current systems for wastewater treatment may have to be improved. In order to evaluate new technologies for municipal wastewater treatment, a development project has been initiated for the new district Hammarby Sjöstad in Stockholm. The project is lead by the company Stockholm Water. High environmental standards have been put up for the district, as it must be twice as good as an ordinary new district.

?-galaktosidas assay för studie av promotorregion i kloritdismutas från Ideonella dechloratans

Oxochlorates are anions with a partially naturally occurrence in nature but are also spread by human activities, including the paper industry. These compounds are harmful to both nature and humans, which makes it necessary to find a good way for their degradation. There are two different kinds of bacteria that can use oxochlorates as electron acceptors in their metabolism, bacteria that break down perchlorate and bacteria that break down both perchlorate and chlorate. A bacterium that can break down chlorate under anAerobic conditions is Ideonella dechloratans which holds the genes for chlorite dismutase and chlorate reductase which are enzymes for the degradation of chlorate. Gene expression and enzyme activity of chlorite dismutase are induced under anAerobic conditions, which makes it interesting to find out how this regulation functions in order to better exploit these bacteria in biological wastewater treatment.

Hydrolys av primärslam för förbättrande av biologisk fosforreduktion vid behandling av hushållsavloppsvatten [Hydrolysis of primary sludge for enhancement of biological phosphorus removal in household wastewater]

Hammarby Sjöstad is a new district of southern Stockholm built with focus on reduced environmental impact by recirculation of materials and sustainability. The environmental goals aim to cut the water consumption by half and a separate storm water treatment. Thus, the wastewater will be more concentrated and will originate from the households only. The Sjöstad project includes the idea of a local treatment plant for the household wastewater. To evaluate this possibility, Sjöstadsverket, an experimental treatment plant was constructed.

Korsförlamning hos häst : fodrets påverkan

The purpose of this thesis has been to gather knowledge about the complaints of tying-up in horses and to show that the importance of feeding. The thesis includes a literature review of tying-up how preventative measures by feeding can be made. In the equine sport, crosscountry, horses occasionally suffers from tying-up, a muscle disease. An increased knowledge about the disease is demanded by riders and trainers as the disease disrupts training and competition of suffered horses. A cross-country horse works very hard in training and during competitions but the work bouts are long enough for the muscle cells to use Aerobic pathways in the metabolism.
