Top athletes weigh in on perceived effectiveness of anti-doping measures

Sciencedaily: Sports Medicine News - Tue, 10/16/2018 - 15:14
Doping remains an ongoing problem in competitive sports, but researchers have never before asked athletes to rank the effectiveness of available anti-doping strategies. A new poll of a national pool of top German cyclists and field athletes finds that, according to the athletes, better diagnostics, increased bans and laws against doping are perceived as far more effective than increased fines or leniency programs.

Cumulative sub-concussive impacts in a single season of youth football

Sciencedaily: Sports Medicine News - Mon, 10/15/2018 - 15:46
In an investigation of head impact burden and change in neurocognitive function during a season of youth football, researchers find that sub-concussive impacts are not correlated with worsening performance in neurocognitive function.

How can we reduce concussions in football? Change kickoffs, experts say

Sciencedaily: Sports Medicine News - Mon, 10/01/2018 - 18:42
A new study points to one way to make American football safer: move the kickoff line.

Creating 3D printed 'motion sculptures' from 2D videos

Sciencedaily: Sports Medicine News - Wed, 09/19/2018 - 15:33
The new system uses an algorithm that can take D videos and turn them into 3D printed 'motion sculptures' that show how a human body moves through space. In addition to being an intriguing aesthetic visualization of shape and time, the team envisions that their 'MoSculp' system could enable a much more detailed study of motion for professional athletes, dancers, or anyone who wants to improve their physical skills.

Long-term success of ACL reconstruction is connected to way you move post-surgery

Sciencedaily: Sports Medicine News - Tue, 09/18/2018 - 15:20
Researchers conducted a study to observe walking biomechanics of 130 subjects who have had ACL reconstruction surgery. They found people who report lingering symptoms post-surgery either underload their injured leg (6-12 months after surgery) or overload the injured leg (after the 24-month mark), as compared to those who have had the surgery but no longer report symptoms.

Researchers find children experience concussion symptoms three times longer than adults

Sciencedaily: Sports Medicine News - Mon, 09/17/2018 - 16:09
Parents should be aware that significant changes in concussion treatment have emerged in recent years. Primarily, there has been a major shift to promoting active recovery -- including a quick return to social, academic, and athletic activities, as well as specialized rehabilitation. Also important is an understanding that children take three times longer than adults to recover from concussion symptoms -- sometimes even longer due to underlying anxiety or depression issues.

Inhaled steroids may increase risk of nontuberculous mycobacteria lung infections

Sciencedaily: Sports Medicine News - Sat, 09/15/2018 - 17:35
Patients using inhaled steroids to control asthma and other breathing problems may be at greater risk for developing nontuberculous mycobacteria (NTM) lung infections, according to new research.

Emotional scars increase the risk of sports injury

Sciencedaily: Sports Medicine News - Fri, 09/07/2018 - 18:04
Active top-flight athletes who have experienced sexual or physical abuse at some time in their life run a greater risk of sports-related injury. A new study has shown an association between lifetime abuse experience and injury risk in female athletes.

Public health researchers warn of dietary supplements containing higenamine

Sciencedaily: Sports Medicine News - Thu, 09/06/2018 - 22:19
A new peer-reviewed study of weight-loss and sports/energy supplements containing higenamine finds unpredictable and inaccurately labeled dosages of the potentially harmful cardiovascular stimulant.

Body clock link to steroids discovered

Sciencedaily: Sports Medicine News - Tue, 09/04/2018 - 23:46
Scientists have discovered that the time of day influences the way mice respond to steroids. Researchers found that out of 752 genes which regulate lungs in mice, 230 genes work only in the day and 197 only at night.

Concussions loosen insulation around brain cells

Sciencedaily: Sports Medicine News - Tue, 09/04/2018 - 17:12
Detailed scans of concussed hockey players found that the protective fatty tissue surrounding brain cell fibers was loosened two weeks after the injury -- even though the athletes felt fine and were deemed ready to return to the ice. A loosening of that insulation, called myelin, slows the transmission of electrical signals between neurons, and shows that passing a concussion test may not be a reliable indicator of whether the brain has truly healed.

Even the fittest middle-aged athletes can't outrun cardiovascular risk factors

Sciencedaily: Sports Medicine News - Fri, 08/31/2018 - 20:01
Middle-aged adults are exercising more and living longer, but new research suggests that even the fittest among them are not immune to cardiovascular disease -- and they often don't have any symptoms.

Tight-knit teammates may conform to each other's behavior

Sciencedaily: Sports Medicine News - Wed, 08/29/2018 - 18:55
In a study with NCAA athletes, researchers found that the more closely a player identified as being part of their team, the more likely they were to conform to their teammates' behavior. This was true for both risky and positive behaviors.

Stabilizing dysferlin-deficient muscle cell membrane improves muscle function

Sciencedaily: Sports Medicine News - Mon, 08/27/2018 - 18:08
In a head-to-head trial between the conventional glucocorticoid, prednisolone, and a modified glucocorticoid, vamorolone, in experimental models of LGMD2B, vamorolone improved dysferlin-deficient muscle cell membrane stability and repair. This correlated with increased muscle strength and decreased muscle degeneration, according to a new study.

Head and neck positioning affects concussion risk

Sciencedaily: Sports Medicine News - Wed, 08/22/2018 - 21:10
The way our head and neck are positioned during a head-on impact may significantly affect the risk of concussion -- but tensed up neck muscles seem to offer far less protection.

Penalty kick research hits the spot

Sciencedaily: Sports Medicine News - Fri, 08/10/2018 - 00:51
New research has come up with the best way to practice penalty kicks if a player favors waiting for the goalkeeper to move rather than just deciding on a spot before taking their penalty.
