For high school baseball pitchers, extra throws on game day add up but go uncounted

Sciencedaily: Sports Medicine News - Wed, 05/02/2018 - 02:33
For high school baseball pitchers, limiting throws during a game helps to prevent fatigue and injuries. But nearly half the number of pitches -- ones thrown during warm-ups and in the bullpen -- are typically not counted, adding significantly to a pitcher's risk of injury, new findings show.

Food for thought: Ketogenic diets reduce athletes' anaerobic performance, study finds

Sciencedaily: Sports Medicine News - Tue, 05/01/2018 - 20:08
Researchers found that after following a ketogenic diet, study participants did not perform as well at anaerobic exercise tasks.

Acute and chronic changes in myelin following mild traumatic brain injury

Sciencedaily: Sports Medicine News - Tue, 05/01/2018 - 15:55
Preliminary research using mcDESPOT magnetic resonance imaging shows changes in the myelin content of white matter in the brain following mild traumatic brain injury. Myelin changes are apparent at the time of injury and three months afterward.

Youth tackle football participation linked to earlier onset of cognitive and emotional symptoms

Sciencedaily: Sports Medicine News - Mon, 04/30/2018 - 20:19
Starting to play tackle football before age 12 could lead to earlier onset of cognitive and emotional symptoms among athletes who were diagnosed with CTE and other brain diseases postmortem, according to a new study.

Get off the golf cart if you have knee osteoarthritis

Sciencedaily: Sports Medicine News - Sat, 04/28/2018 - 21:51
It may seem intuitive that golfers with knee osteoarthritis should stay off their feet and ride in a golf cart. But new research has found, for the first time, that walking the course provides significantly higher health benefits and is not associated with increased pain, cartilage breakdown or inflammation.

Future wearable device could tell how we power human movement

Sciencedaily: Sports Medicine News - Tue, 04/24/2018 - 20:36
For athletes and weekend warriors alike, returning from a tendon injury too soon often ensures a trip right back to physical therapy. However, a new technology could one day help tell whether your tendons are ready for action.

Factors promoting physical activity in childhood

Sciencedaily: Sports Medicine News - Tue, 04/24/2018 - 18:29
Researchers show that the more accurately children assess their motor competences, the more positive is the effect on their physical activity.

Soccer heading -- not collisions -- cognitively impairs players

Sciencedaily: Sports Medicine News - Tue, 04/24/2018 - 18:29
Worse cognitive function in soccer players stems mainly from frequent ball heading rather than unintentional head impacts due to collisions, researchers have found. The findings suggest that efforts to reduce long-term brain injuries may be focusing too narrowly on preventing accidental head collisions.

Children are as fit as endurance athletes

Sciencedaily: Sports Medicine News - Tue, 04/24/2018 - 15:39
Researchers discover how young children seem to run around all day without getting tired: their muscles resist fatigue and recover in the same way as elite endurance athletes. The study, which compared energy output and post-exercise recovery rates of young boys, untrained adults and endurance athletes, can be used to develop athletic potential in children and improve our knowledge of how disease risk, such as diabetes, increases as our bodies change from childhood to adulthood.

A blood test when it is safe to return to play after a sports-related concussion

Sciencedaily: Sports Medicine News - Mon, 04/23/2018 - 18:07
A high-sensitive blood test can aid concussed hockey players when it might be safe to return to play. Researchers have identified a superior blood-based biomarker for assessing subtle brain injury.

Saving a penalty: How science helps predict soccer scores

Sciencedaily: Sports Medicine News - Mon, 04/23/2018 - 18:02
Ever since the first penalty kicks were introduced to soccer in 1891, experts, coaches and supporters have puzzled over the question of why some goalkeepers are better at stopping penalties than others. A new review now demonstrates that simply learning which corner to dive to is not enough. It is important that goalkeepers also perfectly calculate their dive to get to the corner at the right time.

Blood biomarkers may allow easier detection, confirmation of concussions

Sciencedaily: Sports Medicine News - Sat, 04/21/2018 - 00:06
Researchers have found that specific small molecules in blood plasma may be useful in determining whether someone has sustained a mild traumatic brain injury (mTBI), commonly known as a concussion.

Does concussion recovery and symptom severity differ between men and women?

Sciencedaily: Sports Medicine News - Thu, 04/19/2018 - 20:09
A new study comparing male and female athletes examined whether there are clear sex-related differences in post-concussion symptom severity and length of recovery.

Study shows men and women tear ACL the same way in non-contact injury

Sciencedaily: Sports Medicine News - Wed, 04/18/2018 - 16:20
While women are two to four times more likely than men to tear the anterior cruciate ligament (ACL) in their knee, the cause of this injury is no different between the sexes, according to new research.

Brain differences in athletes playing contact vs. Noncontact sports

Sciencedaily: Sports Medicine News - Thu, 04/05/2018 - 19:03
A study has found differences in the brains of athletes who participate in contact sports compared to those who participate in non-contact sports.

How muscles regulate their oxygen consumption

Sciencedaily: Sports Medicine News - Tue, 04/03/2018 - 19:40
A new study shows that an enzyme called FIH determines how muscles consume oxygen. Without the enzyme, the need for oxygen increases during physical exercise. The finding is of potential significance to elite athletes, who have been found to have higher levels of FIH in their muscles than others.

Probing the complex nature of concussion

Sciencedaily: Sports Medicine News - Sat, 03/31/2018 - 00:13
Concussion is a major public health problem, but not much is known about the impacts that cause concussion or how to prevent them. A new study suggests that the problem is more complicated than previously thought.

Top sports leagues heavily promote unhealthy food and beverages, new study finds

Sciencedaily: Sports Medicine News - Mon, 03/26/2018 - 16:03
The majority of food and beverages marketed through multi-million-dollar television and online sports sponsorships are unhealthy -- and may be contributing to the escalating obesity epidemic among children and adolescents in the US.

Tamoxifen and raloxifene slow down the progression of muscular dystrophy

Sciencedaily: Sports Medicine News - Tue, 03/20/2018 - 14:43
Steroids are currently the only available treatment to reduce the repetitive cycles of inflammation and disease progression associated with functional deterioration in patients with muscular dystrophy (MD). A study has shown that a new treatment approach using the selective estrogen receptor modulators (SERMs) tamoxifen and raloxifene significantly improved cardiac, respiratory, and skeletal muscle functions and increased bone density in both male and female mice with the same gene defects as a subset of patients with MD.

Quintupling inhaler medication may not prevent asthma attacks in children

Sciencedaily: Sports Medicine News - Mon, 03/19/2018 - 20:45
Children with mild to moderate asthma do not benefit from a common practice of increasing their inhaled steroids at the first signs of an asthma exacerbation, according to clinical trial results. Researchers found short-term increases in inhaled steroids did not prevent attacks in children aged 5 to 11, and may even slow a child's growth.
