When AC does occur however, it can result in considerable disruption to any tennis activity, especially given the typically long timescale it requires to resolve.
There’s steadily accumulating evidence that one particular group of commonly prescribed antibiotics called ‘fluoroquinolones’ might be implicated in rapid-onset tendon degeneration, exposing sportsmen and women to an increased risk of tendonitis or even tendon rupture.
A recent article in Sports Performance Bulletin looks at the risk of tendon rupture that fluoroquinolone antibiotics pose and explains why sportsmen and women are at particular risk – a risk can last many months after the antibiotic course.
The article explains why any athlete taking common asthma medications should be very careful indeed about fluoroquinolone antibiotic use.
The positive news is that when athletes have to use the antibiotics, there are a number of protocols that can reduce the risk to themselves, and there also evidence that a particular nutrient may also exert a protective effect.

If you’re vaccinated, you should think about a number of variables, including your overall health, where you live and the risks you take.
Many people are seeking definitive answers about what they can and can’t do after being vaccinated against Covid-19. Is it OK to travel? Should I go to a big wedding? Does the Delta variant make spending time with my vaccinated grandmother more risky?
But there’s no one-size-fits-all answer to those questions because risk changes from one individual to the next, depending on a person’s overall health, where they live and those they spend time with. The bottom line is that vaccines are highly protective against serious illness, and, with some precautions, will allow people to return to more normal lives, experts say. A recent study in Los Angeles County showed that while breakthrough infections can happen, the unvaccinated are 29 times as likely to end up hospitalized from Covid-19 as a vaccinated person.
Experts say anxiety about breakthrough infections remains pervasive, fueled in part by frightening headlines and unrealistic expectations about the role of vaccines.
“There’s been a lot of miscommunication about what the risks really are to vaccinated people, and how vaccinated people should be thinking about their lives,” said Dr. Ashish K. Jha, dean of the Brown University School of Public Health. “There are people who think we are back to square one, but we are in a much, much better place.”
While the Delta variant is causing a surge in infections in various hot spots around the country, including Florida and Louisiana, there will eventually be an end to the pandemic. Getting there will require ongoing precautions in the coming months, but vaccinated people will have more freedom to enjoy life than they did during the early lockdowns. Here are answers to some common questions about the road ahead.
What’s my risk of getting Covid if I’m vaccinated?
To understand why there is no simple answer to this question, think about another common risk: driving in a snowstorm. While we know that tens of thousands of people are injured or killed each year on icy roads, your individual risk depends on local conditions, the speed at which you travel, whether you’re wearing a seatbelt, the safety features on your car and whether you encounter a reckless driver on the road.
Your individual risk for Covid after vaccination also depends on local conditions, your overall health, the precautions you take and how often you are exposed to unvaccinated people who could be infected.
“People want to be told what to do — is it safe if I do this?” said Dr. Sharon Balter, director of the division of communicable disease control and prevention at the Los Angeles County Department of Public Health. “What we can say is, ‘These are the things that are more risky, and these are the things that are less risky.’”
Dr. Balter’s team has recently collected surveillance data that give us a clearer picture of the difference in risk to the vaccinated and unvaccinated as the Delta variant surged from May 1 through July 25. They studied infections in 10,895 fully vaccinated people and 30,801 unvaccinated people. The data showed that:
- The rate of infection in unvaccinated people is five times the rate of infection in vaccinated people. By the end of the study period, the age-adjusted incidence of Covid-19 among unvaccinated persons was 315.1 per 100,000 people over a seven-day period compared to 63.8 per 100,000 incidence rate among fully vaccinated people. (Age adjustment is a statistical method used so the data are representative of the general population.)
- The rate of hospitalization among the vaccinated was 1 per 100,000 people. The age-adjusted hospitalization rate in unvaccinated persons was 29.4 per 100,000.
- Older vaccinated people were most vulnerable to serious illness after a breakthrough infection. The median age of vaccinated people who were hospitalized for Covid was 64 years. Among unvaccinated people who were hospitalized, the median age was 49.
- The Delta variant appears to have increased the risk of breakthrough infections to vaccinated people. At the start of the study, before Delta was dominant, unvaccinated people became infected 10 times as often as vaccinated people did. By the end of study period, when Delta accounted for almost 90 percent of infections, unvaccinated people were five times as likely to get infected as vaccinated people.
What’s the chance of a vaccinated person spreading Covid-19?
While unvaccinated people are by far at highest risk for catching and spreading Covid-19, it’s also possible for a vaccinated person to become infected and transmit the illness to others. A recent outbreak in Provincetown, Mass., where thousands of people gathered in bars and restaurants, showed that vaccinated people can sometimes spread the virus.
Even so, many experts believe the risk of getting infected from a vaccinated person is still relatively low. Dr. Jha noted that after an outbreak among vaccinated and unvaccinated workers at the Singapore airport, tracking studies suggested that most of the spread by vaccinated people happened when they had symptoms.
“When we’ve seen outbreaks, like those among the Yankees earlier in the year and other cases, almost always people are symptomatic when they’re spreading,” Dr. Jha said. “The asymptomatic, pre-symptomatic spread could happen, but we haven’t seen it among vaccinated people with any frequency.”
Another study from Singapore looked at vaccinated and unvaccinated people infected with the Delta variant. The researchers found that while viral loads in vaccinated and unvaccinated workers are similar at the onset of illness, the amount of virus declines more rapidly in the vaccinated after the first week, suggesting vaccinated people are infectious for a shorter period of time.
Is it still safe to gather unmasked with vaccinated people?
In many cases it will be safe, but the answer depends on a number of variables. The risk is lower with a few close family members and friends than a large group of people you don’t know. Outdoor gatherings are safer than indoor gatherings. What’s the community transmission rate? What’s the ventilation in the room? Do you have underlying health issues that would make you vulnerable to complications from Covid-19? Do any of the vaccinated people have a fever, sniffles or a cough?
“The big question is can five people sit around a table unmasked if we know they’re all vaccinated,” Dr. Jha said. “I think the answer is yes. The chances of anybody spreading the virus in that context is exceedingly low. And if someone does spread the virus, the other people are not going to get super sick from it. I certainly think most of us should not fear breakthrough infections to the point where we won’t tolerate doing things we really value in life.”
For larger gatherings or even small gatherings with a highly vulnerable person, rapid antigen testing using home testing kits can lower risk. Asking people to use a test a few days before the event, and then the day of the event, adds another layer of protection. Opening windows and doors or adding a HEPA air cleaner can also help.
The study found that adults who reported frequently participating in tennis or other racket and team sports lived longer than people who were sedentary. But they also lived longer than people who took part in reliably healthy but often solitary activities such as jogging, swimming and cycling.
The results raise interesting questions about the role that social interactions might play in augmenting the benefits of exercise.
At this point, no one doubts that being physically active improves our health and can extend our longevity. Multiple, recent epidemiological studies have pinpointed links between regular exercise and longer lives in men and women.
But whether some activities might be better than others for lengthening life spans remains in dispute. One widely publicized 2017 study of more than 80,000 British men and women found that those who played racket sports tended to outlive those who jogged.
Those results piqued the interest of an international group of scientists. They previously had examined links between jogging and longevity and concluded that moderate amounts of moderately paced running led to greater gains in longevity than more-gentle or strenuous running.
For the new study, which was published this week in Mayo Clinic Proceedings, these same researchers decided to widen their inquiry and look at a variety of sports and their associations with life and premature death.
To start, they turned to the same data resource they had used for the jogging study, the Copenhagen City Heart Study, an ambitious, ongoing attempt to track the lives and health of thousands of men and women in Copenhagen.
The study’s participants had all completed health exams and lengthy questionnaires about their lifestyles and whether and how often they took part in eight sports common in Denmark, including cycling, swimming, running, tennis, soccer and, perhaps unexpectedly, badminton.
The researchers zeroed in on 8,600 of the participants who had been part of the study for about 25 years.
They cross-referenced records with the national death registry to see if and when any of these people had passed away.
Then they compared activities and life spans.
The most obvious finding was that people who had reported almost never exercising were more likely than the active to have died in the ensuing decades.
The associations between particular activities and life span were more surprising.
Cycling was the most popular activity among the Danes in the study, many of whom reported riding for four or more hours every week. Their pedaling was associated with a lengthier life span, adding an average of 3.7 years to riders’ lives, compared to sedentary Danes.
Running likewise was associated with an extra 3.2 years of life.
But these gains were notably less than for playing tennis, which was linked to 9.7 added years of life, or badminton, which was linked to an extra 6.2 years, or soccer, which added almost 5 years to players’ lives.
These associations remained unchanged even when the researchers controlled for people’s education, socioeconomic status and age.
Why and how some sports might add more years to people’s lives than others is impossible to know from this kind of observational study, says Dr. James O’Keefe, a study co-author and the director of preventive cardiology at the Mid America Heart Institute at Saint Luke’s Health Center in Kansas City.
The differing physical demands of some sports could play a role, he says, although little of the exercise in this study was heavily intense, whether people were cycling or backhanding a shuttlecock.
Income and other aspects of people’s lifestyles also likely matter, he says. The researchers tried to account for socioeconomic factors, but it remains possible, he says, that people who have sufficient money and leisure time to play tennis live longer because they have sufficient money and leisure time, not because they play tennis.
Still, he suspects that the social aspects of racket games and other team sports are a primary reason that they seem to lengthen lives, he says.
“We know from other research that social support provides stress mitigation,” he says.
“So being with other people, playing and interacting with them, as you do when you play games that require a partner or a team, probably has unique psychological and physiological effects,” he says, amplifying the benefits of the exercise.
That possibility requires verification, he says, especially in randomized experiments directly comparing different types of exercise.
But for now, people who run or ride solo might consider finding a group or partner with whom to work out, he says.
“Raising your heart rate is important” for health, he says. “But it looks like connecting with other people is, too.”
How Walking, Dancing, Tennis Can Build Up the Brain
Exercise can freshen and renovate the white matter in our brains, potentially improving our ability to think and remember as we age, according to a new study of walking, dancing (tennis) and brain health.
The Olympic tennis tournament will be missing some of the sport’s bigger names this year, but there’s still plenty of star power to go around in Tokyo. Tennis’s best-known players have often shined at the Olympics — past gold medalists in singles include Steffi Graf, Jennifer Capriati, Venus Williams and Serena Williams on the women’s side, and Andre Agassi, Rafael Nadal and Andy Murray on the men’s side.

What is the Olympic tennis format?
The men’s and women’s singles medals will be decided by a 64-player, single-elimination tournament. Doubles will feature 32 teams and mixed doubles 16 teams.
All four players or teams to reach the semifinals will compete for medals, with the two semifinal losers playing for bronze and the winners playing for gold (or silver).
Sixteen of the 64 players in singles are seeded based on international rankings, while eight of 32 are seeded in doubles. When possible, no two players from the same country are placed in the same quarter of the draw.
All matches are best-of-three sets. All singles matches will feature a standard tiebreaker (first to seven points) in every set. In doubles, if the teams split the first two sets then the third set will consist entirely of a first-to-10-points tiebreaker.
When is the Olympic tennis tournament?
