When women enter menopause, estrogen levels drop and that is linked to increased risk of cardiovascular disease, but research from  University of Copenhagen’s Centre for Team Sport and Health finds that interval-based team sport can make up for this estrogen loss.

Estrogen, the primary female sex hormone, is an important guardian of the female vascular system. Thus, s oestrogen levels fall during menopause, the risks of increased blood pressure and development of cardiovascular disease increases.  Team sports improve the condition of women, reduces blood pressure and thus protects the cardiovascular system.  

In soccer, a team is most vulnerable to being scored on right after they score. Pundits and psychologists attribute that to overconfidence. Yet in the 2014 Super Bowl, the Seattle Seahawks dominated early and the Denver Broncos looked increasingly disorganized. Pundits and psychologists attribute that to momentum.

Momentum or overconfidence are often applied in hindsight to individual games but what about during winning streaks? Is what analysts term momentum a kind of competitive inertia, where a team in a state of winning tends to keep winning? 

No, say economists writing in Economics Letters, after examining varsity college hockey teams winning and losing records. Momentum advantages don't exist.

Older football veterans contend that modern equipment, and its ability to protect players from injury, ironically lead to more of it. Rugby players agree. 

They may be right. A new study finds that modern football helmets do little to protect against hits to the side of the head and the rotational force that is often a dangerous source of brain injury and encephalopathy. 

Does home field advantage matter? In baseball outfielders, the tricks and corners of a new baseball park might be meaningful but that effect should diminish over time. The Seattle Seahawks have a famously loud stadium and the team calls the audience "the twelfth man" but they didn't need it to rout the Denver Broncos in the Super Bowl.

There are no athletes in the Olympics who are from Sochi, yet psychologists believe that Russian athletes will have a psychological edge, even though Russia covers 6,600,000 million square miles, because they have a home field advantage.

In every sport, an athlete who has enjoyed long-term success has the opportunity for free agency, when they can join the highest bidder.

A new paper finds that concussions are common among middle-school girls who play soccer, and most continue to play with symptoms.

Using a small sample of email survey and interviews, the authors evaluated the frequency and duration of concussions in young female soccer players, as well as whether the injuries resulted in stopping play and seeking medical attention.  There are no injury-tracking systems for younger players but the background information says that sports-related concussions account for 1.6 to 3.8 million injuries in the United States annually, including about 50,000 soccer-related concussions among high school players.

Managers of fantasy sports teams - where people draft rosters filled with players of their own choosing - spend countless hours and sometimes thousands of dollars on analysis to develop a sophisticated method of getting the best roster.

And sometimes, just like real sports, some superstition is involved.

But most fantasy sport players overestimate the role of skill and knowledge in building a winning team, and underestimate the role of luck, according to a paper in the Journal of Sports Management

Doping advocates are just as likely to do the brain kind if they do the body kind, according to survey results of about 3,000 hobby triathletes at sporting events in Frankfurt, Regensburg, and Wiesbaden.

The work by Johannes Gutenberg University Mainz (JGU) and Eberhard Karls University in Tubingen was carried out using the randomized response technique, which allows for better estimates of unknown cases in response to sensitive questions. It suggested that 13.0 percent of the athletes surveyed had used illegal and banned substances in the twelve months prior to the survey; 15.1 percent were believed to have engaged in brain doping. revealed that people who engage in physical doping often also take drugs for brain doping.

Everyone has seen what athletes do after a victory - footballers may take their shirts off and slide on their knees, baseball hitters may pump their fists. 

That instinctive reaction that occurs is a biological imperative to display dominance over opponents rather than a sense of personal satisfaction, according to a paper in Motivation and Emotion.

The XVIth international chess tournament "Citta' di Padova" ended last Sunday with the victory of GM Kiril Georgiev, who got 7 points out of 9 games. The tournament saw the participation of 63 players from 13 countries, with a total of 11 grandmasters and 13 international masters, plus nine other Fide titled players.

I participated in the event and scored a good 4.5/9, winning four games and losing four. Below I am showing some salient points from a few of my games.
