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.

The purpose of the study was to investigate whether or not Icelandic horses are less severely affected in clinical symptoms of cough or decreased performance than other breeds of horses. A breed variation in chronic respiratory disease severity was suspected based on clinical experience at the Institution for surgery & medicine, large animal, SLU Uppsala. A retrospective journal study of 17 Icelandic horses and 17 Swedish Standardbred horses with chronic problems with cough and/or decreased performance compared several measurements of disease severity. The clinical signs, physical examination and laboratory testing results compared were respiratory rate, abdominal breathing, lung auscultation, endoscopy results, broncho-alveolar lavage (BAL) results and the blood gases pO2 and pCO2. All parameters were available for all 34 individuals except for the blood gases, which were analysed, in only four Icelandic horses and four Swedish Standardbred horses. The only parameters that appeared different between the two groups were respiratory rate and pO2. The four Icelandic horses, which had blood gases analysed, had more severe hypoxemia.

Background: Testosterone is the most important androgenic hormone in the male. Aging is closely associated with reduction of serum testosterone which can lead to reduced muscle mass, muscle strength, bone density, and depression. These symptoms may be counteracted by administration of testosterone. Objective: The purpose of this study was to examine the effects of hormone replacement in men with age-related testosterone deficiency. Method: We performed a systematic review using Randomised Controlled Trials (RCT).

ABSTRACT Background: Health and ill-health are multifaceted concepts. Previous research has shown that physical activity and the level of cardio respiratory are important parts of leading a healthy lifestyle. Possibly, it?s so important that the Occupational Health Service should focus even more on this.Aim: The aim was to investigate if there was a relationship between the level of cardio respiratory fitness and self-rated health, and between the level of cardio respiratory fitness and physical and mental ill-health.Method: The study was conducted using a quantitative method in the form of a cross sectional study. Data was collected from an Occupational Health Service, containing answers to a questionnaire on work environment and health and test values ??from completed cycle fitness tests.

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 %).

Introduction: A complex interaction between muscles, tendons, bones, joints and nerves are required for optimal function of the human hand. It is known that an individual?s grip strength is vital for performance of physical demanding tasks such as strength training with free weights. Strength training including a thicker grip around the bar may enhance the strength of the grip in the athlete without other special routines for grip strength development. The purpose of this investigation was to examine the difference in performance in multiple repetitions in two strength training exercises using two different sizes on the bar, to look for correlations between grip strength of the subjects hand and the amount of repetitions executed with two different size of the bar and finally the correlation of hand size and the amount of repetitions executed with two different size of the bar.Method: 15 strength training men (23,9 ± 4,1 years), underwent measurements of hand size, maximum grip strength, 1 repetition maximum (1RM), a 80 % of 1RM weight strength test with two different  bar sizes.Results: The results from the present investigation indicates a 21,1 % reduction of 80 % of 1 RM weight performance in repetitions executed in the bench press with the thicker diameter of the bar and a 66,2 % reduction in repetitions executed with a 80 % of 1 RM weight in the lying bench row with the thicker diameter of the bar.

The conservation of great apes faces many challenges, one of which is the threat of infectious disease outbreaks. Zoonotic transmission of respiratory diseases from humans to wild great apes has recently been confirmed. Since respiratory disease is one of the major causes of death in both gorillas and chimpanzees, this gives reason for major concern. Little is known about the risks of disease transmission from humans to great apes in natural environments, and there is a need for systematic risk evaluation. Researchers, conservation staff and tourists spend time in very close proximity of wild great apes, sometimes during long time periods, which poses a potential risk of disease spillover. However, the presence of researchers and tourists has been shown to decrease the risk of poaching, making the matter increasingly complex.

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.

Respiratory infections are one of the major causes of disease in sheep throughout the world. In the beginning of 2008 the Swedish National Veterinary Institute and the Swedish Animal Health Service together started a project about respiratory infections in Swedish sheep. This study is an initial part of that project and the aim of this study was to investigate different sampling possibilities with focus on nasal swabs. This study is composed partly of a literature review on causative agents of respiratory infections in sheep and existing sampling methods, and partly of an experimental study comprising 56 sheep. These sheep were sampled with both an ordinary nasal swab and a guarded nasal swab. Before the start of this study there was to our knowledge no described method for sampling sheep with a guarded swab.

During football games neuromuscular fatigue occuring following eccentric movements such as sprint, jump and run that occur during games. To avoid injury, overtraining and performance decreases, it is important to know when players are recovered. The aim of the pilotstudy was to investigate physiological changes that occur during football matches and if they affect the recovery pattern after several games in professional football players. The method was divided into two sub-studies in which 12 professional footballers, in substudy 1 performed counter movement jump (CMJ) and drop jump (DJ) from 40 cm and fill out a recovery form for muscle soreness 36 hours before, 12-16 and 60-64 hours after 11 different competetive games. Blood samples were taken on the players in connection with one match to examine the activity of muscle enzyme creatine kinase (CK) and lactate dehydrogenase (LDH) of the players.

Vissa studier som undersökt kombinerad styrketräning och uthållighetsträningjämfört med styrketräning har funnit hämmad styrkeutveckling vid kombinerad träning. Forskning har därför riktats mot att undersöka hur hämmad effekt kan undvikas. 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.

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.

Glycogen is the storage form of glucose and is used by the skeletal musculature as energy both for intense and endurance events. The glycogen content in the horse?s middle gluteal muscle is more than 600 mmol/kg dry weight, and almost 400 mmol/kg dry weight in the human?s Vastus lateralis. In some special occasions, for example in competitions with several moments on following days, there is a need of a fast muscle glycogen resynthesis. The feed intake is of importance for the velocity of the resynthesis.

 Background: Earlier studies show that 30-92 % of ACL reconstructed return to their pre-injury physical activity. It is not clear why some people do not return.Purpose: The purpose of this study was to investigate the return rate to pre-injury sport among ACL reconstructed men. Another purpose was to characterize those patients who return and those who do not.Metod: A Web-based questionnaire with questions about returning to physical activity was sent out during the spring of 2012 to 93 men who had undergone an ACL reconstruction 6-40 months earlier and who, after 6-40 months after surgery, were evaluated with validated strength tests and self-assessment outcome measures.Results: At 12 months after surgery 56 % of the subjects had returned to their pre-injury sport. If the criteria were set higher ?back to the same- or a higher level? 14 % had returned.

In this study it has been investigated what is missing in non-strength training women to begin exercise regular strength training. It has also examined the level of knowledge about the health benefits and the employer's encouragement to maintain good health. The study was designed in a qualitative methodology and data collection was designed in form of semi-structured interviews. Six women were interviewed between the ages 22-51år. The results showed that women possessed a very low level of knowledge about strength training and also fears and prejudices existed among them.
