Cranfield University trying to minimize sporting injuries

Posted By

Cranfield University trying to minimize sporting injuriesAccording to the Centre for Sports Surfaces, Cranfield University and the University of Exeter’s Sports Science Department, investigations have been initiated to enhance the engineering of sporting surfaces besides increasing the surface quality and longevity to reduce the possibilities of injuries.

The project, which is to be funded by the Engineering and Physical Sciences Research Council, is looking to develop a new model for predicting the behavior of sporting surfaces with an aim to reduce the number of sporting injuries. This project will be responsible for investigating the integration between soil mechanics and human biomechanics to reduce the possible risks.

Dr Iain James, the project’s Principal Investigator, said that he is delighted that the project is being funded because findings of this project may prove to be beneficial in making sizeable advances in the improvement of natural sports pitches.

David Winn, Training and Education Manager at the Institute of Groundmanship, added that this kind of a project will add to the professionalism of the groundsmen who are looking to create safer and consistent sporting surfaces.

Children taking steroid drugs for nephrotic syndrome are safe from bone lossAccording to a new study, children who take steroid drugs for nephrotic syndrome do not suffer bone loss, which is a common side-effect of steroid treatment methodologies in adults.

Childhood nephrotic syndrome, which is believed to affect 3 out of 100,000 children, is one of the most common chronic kidney ailments in children. Though it does not impair functions of kidney, it weakens the human body’s ability to remove salt and water from the blood to cause swelling in the legs, belly, and around the eyes.

Dr. Leonard said that the findings of this report can be used to assure parents and doctors about steroid treatments for helping children with nephrotic syndrome as steroids do not enhance their risk of osteoporosis.

Changes in sex steroids affect sleep

Posted By

Changes in sex steroids affect sleepIn a study conducted by a team led by principal investigator Mary Fran Sowers, PhD, professor of epidemiology at the University of Michigan, postmenopausal women had longer sleeping time and tend to sleep deeper than pre-menopausal women. This is due to the changes in the follicle stimulating hormone (FSH) found in the body. FSH levels are normally low during childhood and high after menopause. Faster FSH changes were associated with slow wave sleep and longer sleep duration. It was also associated, however, with poorer self-reported sleep quality.

The investigators found that the rate of change in FSH due to menopause transition is mainly the predictive factor of women’s sleeping patterns. These changes occurred and were measured during a seven-year period.

Furthermore, it was noted that women who are nearing the final stages of their menopause cycle have longer uninterrupted sleeping time than those in the early stages of their menopause cycle.

Furthermore, there were some studies presented that provide evidence of improvement in the sleep quality of post menopausal women with the use of hormone replacement therapy. This proposal for therapeutic use, however, can only relieve selected aspects of sleep quality and is not an overall solution for this particular issue.

According to Medical News Today:

Sixty-seven percent of women included in the sleep study were classified as premenopausal (no change in menstrual bleeding regularity) and early perimenopasual (menses in the preceding three months with an increase in bleeding irregularity), 21 percent were identified as late perimenopasual (menses in the previous 12 months, but not in the previous three months), and 11 percent were classified as postmenopausal (12 months of amenorrhea). The median age was 52 years and median body mass index (BMI) was 28 kg. Women slept for a median of nearly six-and-a-half hours per night of the study with a median 40 minutes of wakefulness following sleep onset.

Steroids found to cause temporary disability after injection

Posted By

Steroids found to cause temporary disability after injectionSteroids provide rapid pain relief and anti-inflammatory properties. These properties make it so popular in the treatment of shoulder or rotator cuff injury and other tendon-related injuries. However, a recent study showed that steroids injection can actually produce temporary weakening of the tendons and surrounding tissues right after steroid injection. Patients should rest for a few weeks before returning to their regular activities or begin physical therapy sessions.

According to the senior study investigator Dr. John Callaci, an assistant professor in the Loyola University Department of Orthopedic Surgery and Rehabilitation in Chicago, steroid injection brings about a response to tissues similar to a tendon injury. Tendons usually behave like it thinks it has been acutely injured. It will then produce things that it normally produces when it is injured in order to heal itself. This mechanism may produce temporary instability.

The researchers are currently conducting further research to determine if steroids affect the strength, stress, strain and elasticity of tendons. They are still in the process of investigating the basis of how tendons heal and how steroids may help in the healing process. They further added that they want to determine certain information such as changes in biomechanical properties after steroid injection, amount of scar formation after using steroids and other changes a tissue undergoes after treatment.

According to Dr. Callaci as quoted by Medical News Today:

“We found that steroid injections cause a tendon to behave in a way where it thinks it has been acutely injured,” noted Callaci. “Steroids rapidly provide anti-inflammatory and pain relief. That is why steroids are so popular, but physical therapy also can produce some of the same effects. It just takes longer.”

New test can detect new endurance drugs

Posted By

New test can detect new endurance drugsA team of researchers in Germany, led by Mario Thevis, Director of the Center for Preventive Doping Research at the German Sport University of Cologne, developed a new kind of test to detect a class of compounds known as benzothiazepines.

Benzothiazepines are known to treat variant angina, drug-induced, stable or naturally-occurring. Drugs such as Diltiazem contain this compound.

This compound is known to stop calcium leaking out of the muscles. Calcium is very important in obtaining optimum muscle contractions, end if it leaks out, then this would cause weakening and eventually, muscle fatigue.

Compounds in their early stage of development, especially when they have not undergone any human clinical trials, may be left undetected. In the past, tests are usually developed only after a drug is known to be in circulation.

This time, however, the researchers obtained molecular “fingerprints” of this compound to be used for future testing to trace JTV-519 and S-107 benzothiazepines. This is to help sports officials prepare for any future misuse of the drug. The test is ultra sensitive that it can even detect small concentrations of the compound found in urine to as low as 0.1 nanograms per milliliter.

According to Mario Thevis from Science Daily:

“We used the common approaches that are employed for detecting anabolic agents. Our work showed that we could identify the right compounds and that we have a sensitive test,” says Thevis.

Use of steroids not just limited to athlete girlsThe usage of steroids is not just limited to those girls involved in competitive athletics. According to a national survey published in the June issue of Archives of Pediatrics & Adolescent Medicine, steroid use in girls is also associated with a cluster of harmful behavior patterns such as diet pills and smoking.

Diane L. Elliot, M.D., of the Oregon Health & Science University, Portland, and colleagues made assessed anabolic steroids among young girls during a study that involved 7,544 female students in grades nine through 12 completing the survey.

The study pointed out high-risk adolescent girls received less attention than adolescent boys suggesting that their actions are more destructive on a personal front.

Young Children using drugs to win at sportAs per the findings of French researchers that were published in the British Journal of Sports Medicine, children as young as eleven are using drugs to enhance their sporting performance and stay ahead of the competition.

It was also found during the study that while 44 percent of children under eleven confessed to use of steroids in sports, the number got increased from 1.2 to 3.0 percent in case of children who celebrated their 15th birthday.

This study was concerned with the use of drugs banned under the World Anti-Doping Agency International Standard and involved answers to questions asked from 3,500 eleven-year olds.

Reduce MS activity found during steroid administration

Posted By

Reduce MS activity found during steroid administrationThe Danish Multiple Sclerosis Research Center at Copenhagen University Hospital in Denmark conducted a study of adding methylprednisolone in the treatment of multiple sclerosis (MS) patients.

The study involved patients with relapsing-remitting MS and who had the disease for an average of three years. The treatment group received both interferon and methylprednisolone, while the control group received the interferon drug and a placebo. The study lasted for three years and the participants were only seen every three months.

The researchers measured the size of the brain lesions at the initial phase and again after a period of three years. They found that those in the treatment group, their lesions either stayed the same size or it shrunk while the lesions grew in size for those in the control group. The sign of disease activity is measured primarily by the size of the lesion in the brain.

Furthermore, those who received both drugs have fewer incidences of relapses while those receiving interferon only have a 38% higher rate of relapse. In terms of MS disability tests, the treatment group improved slightly higher than the control or placebo group.

These results might be an indication that there is a synergy between the two drugs which can provide more benefits than interferon alone.

According to Science Daily:

“These results indicate that these two drugs may have a synergy when taken together and provide a more beneficial effect on the disease activity,” said study author Mads Ravnborg, MD, of the Danish Multiple Sclerosis Research Center at Copenhagen University Hospital in Denmark. “This is a promising finding, as the benefit from interferon is only moderate and not everyone responds fully to the treatment, so anything we can do to boost those results is positive.”

Steroids can prove good for professional athletes and bodybuildersAnabolic steroids such as Winstrol (Stanozolol) and Anavar (Oxandrolone or Oxandrin) are regaining huge markets in the US marketplace due to their unparalleled benefits and minimal or almost zero side-effects, when used in a discriminate manner.

Though both of these steroids were previously considered to be greeted with suspicious eyes, recent medical developments have suggested that they can be beneficial to everyone from a bodybuilder to a normal individual spending his time in the gymnasium.

In order to reap optimum benefits from Winstrol and Anavar, they can be stacked with other anabolic substances such as Dianabol, Deca Durabolin, and Clomid.

Exercises make workers productiveAccording to a presented research at the 52nd American College of Sports Medicine (ACSM) Annual Meeting in Nashville, Tennessee, the quality of work, time management, and mental performance of workers is better on days when they exercise before arriving at their workplace.

It was found during the study that workers, after exercises, return to work more tolerant and more forgiving to themselves and others. The study also indicated that as much as 65 percent of workers showed improvements in areas of managing time and output demands in addition to a more stable mental and interpersonal performance when they exercised before coming to office.

As per lead researcher Jim McKenna, Ph.D., there is a plan in pipeline for the university employees, which is based on the study findings.
