Antihistamines could reduce the body’s ability to recover after vigorous exercise by nearly a third scientists have found.

About 3,000 genes have been found to be responsible for aiding recovery, by boosting muscles and blood vessels, but in the presence of high doses of antihistamines almost 27 percent of the gene response is blunted, scientists from University of Oregon have found. However quite how these 795 affected genes could affect competitive athletes, however, is not known, said co-author John R. Halliwill, professor of human physiology.
Histamine is a substance in the body that responds to pollens, moulds, animal dander, insect bites and other allergens, however some people’s body goes in overdrive and fuels uncomfortable allergic reactions, prompting the use of antihistamines.
In the research, 10 men and six women, all 23-25 years old, physically fit and active, performed an hour of knee-extension exercise at 60 percent of their peak power, about 45 kicks per minute. Biopsies were done before and three hours after exercise to obtain samples of the quadriceps.
Eight participants took 540 milligrams of fexofenadine and 300 milligrams of ranitidine — levels nearly three times the recommended dosages of the over-the-counter antihistamines. Each target one of the two known histamine receptors involved in recovery responses. During exercise, blood flow, blood pressure and heart rate were monitored.
The antihistamines had no effect prior to exercise and little influence on gene expression at the conclusion of the workout. Three hours after exercise 88 percent of the 795 genes affected by the antihistamines mostly responded with lower levels of expression.
“Histamine, a substance that we typically think of negatively and is most often associated with seasonal allergies, is an important substance contributing to the normal day-to-day response to exercise in humans,” said Romero, In their conclusion, the authors noted that the research highlighted only a small fraction of genes likely involved in signalling pathways influenced by histamine receptors activation during recovery.
However it is to early in the research to suggest people should avoid taking antihistamines when they exercise, Halliwill said.

“We’ve got more work that we have to do,” he said. “We need to do a training study in which we put people on histamine blockers and see if their adaptations to exercise training are as robust or diminished. There are a lot of redundancies in physiological systems. I wouldn’t be surprised if blocking histamine receptors ends up being overcome by something else, but I also wouldn’t be surprised if we can demonstrate that some responses to exercise training do become blunted if you take high doses of histamine blockers.”
The Trump name graces apartment towers, hotels and golf courses. Now it is the namesake of a tiny Israeli settlement in the Israel-controlled Golan Heights. Israeli Prime Minister Benjamin Netanyahu’s Cabinet convened in this hamlet Sunday to inaugurate a new settlement named after Donald Trump in a gesture of appreciation for the U.S. president’s recognition of Israeli sovereignty over the territory.
The settlement isn’t exactly new. Currently known as Bruchim, it is over 30 years old and has a population of 10 people.Israel is hoping the rebranded “Ramat Trump,” Hebrew for “Trump Heights,” will encourage a wave of residents to vastly expand it.
“It’s absolutely beautiful,” said U.S. Ambassador David Friedman, who attended Sunday’s ceremony. Noting that Mr. Trump celebrated his birthday Friday, he said: “I can’t think of a more appropriate and a more beautiful birthday present.”Israel captured the Golan Heights from Syria in the 1967 Mideast war and annexed it in 1981. Most of the international community considers the move illegal under international law.But during a visit to Washington by Netanyahu in March, just weeks before Israeli elections, Mr. Trump signed an executive order recognizing the strategic mountainous plateau as Israeli territory. The decision, the latest in a series of diplomatic moves benefiting Israel, was widely applauded in Israel.”Few things are more important to the security of the state of Israel than permanent sovereignty over the Golan Heights,” Friedman said. “It is simply obvious, it is indisputable and beyond any reasonable debate.”After the Cabinet decision, Netanyahu and Friedman unveiled a sign trimmed in gold with the name “Trump Heights” and adorned with U.S. and Israeli flags. the president retweeted photos Friedman posted of the event and thanked Netanyahu “and the State of Israel for this great honor!”Addressing the ceremony, Netanyahu called Mr. Trump a “great friend” of Israel and described the Golan, which overlooks northern Israel, as an important strategic asset.”The Golan Heights was and will always be an inseparable part of our country and homeland,” he said.
Developing Ramat Trump will not be easy. Ringed by high yellow grass and land mines, it is roughly 20 kilometers (12 miles) from the Syrian border and a half hour drive from the nearest Israeli town, Kiryat Shmona, a community of about 20,000 people near the Lebanese border.According to Israeli figures, almost 50,000 people live in the Golan, including about 22,000 Jewish Israelis and nearly 25,000 Arab Druze residents.While Israel has encouraged and promoted settlement in the Golan, its remote location, several hours from the economic center of Tel Aviv, has been an obstacle. The area is home to small agriculture and tourism sectors but otherwise has little industry.The eight-year Syrian civil war, which at times has resulted in spillover fire into the Golan, also could present an obstacle to luring new residents.Zvi Hauser, an opposition lawmaker who formerly served as Netanyahu’s Cabinet secretary, called Sunday’s ceremony a cheap PR stunt.”There’s no funding, no planning, no location, and there’s no real binding decision,” he said.Ramat Trump joins a handful of Israeli places named after American presidents, including a village for Harry S. Truman, who first recognized the Jewish state, and George W. Bush Plaza, a square the size of a modest living room in central Jerusalem.
These prestigious annual awards celebrate the outstanding achievements of sportsmen and sportswomen around the world and other great names recognised included tennis players Serena Williams and Novak Djokovic, and the Kiwi rugby team the All Blacks.

Click: London — A woman is facing criminal charges in Northern Ireland for getting her 15-year-old daughter abortion pills to end an unwanted pregnancy in 2013. The woman’s lawyer says the police were alerted after the daughter, who was in an abusive relationship, told a therapist she had taken the pills. The woman’s legal team is challenging the prosecution.
Abortion is against the law in Northern Ireland except when a pregnant woman’s health is at risk of permanent harm. There are no exceptions in cases of rape or incest. Women who have illegal abortions can face up to life in prison if caught, and medical professionals are required to report anyone who has had one to the authorities. The mother faces a sentence of up to five years in jail for procuring and supplying abortion pills to her daughter. If she had administered them, she could have faced life in prison.
Healthcare providers in Northern Ireland had been fearful of a situation that would pit them against the country’s strict abortion laws in the course of their work, Suzanne Tyler, executive director of the Royal College of Midwives, told CBS News.She said the case shows that the “theoretical risk” posed by the laws has now become “a very real situation,” demonstrating that Northern Irish prosecutors are willing to charge people over illegal abortions that are disclosed during the course of medical treatment. Women have been prosecuted for having illegal abortions in Northern Ireland before, but this is the first time the decision by prosecutors to pursue these types of charges has been challenged. A court in Northern Ireland is reviewing the decision as part of a process knows as “judicial review.” The court has the power to strike down the charges, and there has not yet been a decision. Despite the fact that the judicial review is ongoing, a criminal court date has been set for the mother for November 18, 2019. Amnesty International says the court date was set on Tuesday, despite there not yet being an outcome in the judicial review.A long fightThe mother, whose name has not been shared to protect her and her daughter’s privacy, has been fighting the case for more than five years, arguing that criminal prosecution would violate her rights under the European Convention on Human Rights.”An innocent family is being prosecuted for being open and transparent with medical professionals,” Jemma Conlon, the mother’s attorney, told CBS News.”This is a private family matter,” Conlon said. “It has caused immense distress and anguish for nearly 5.5 years.”Grainne Teggart, head of campaigns in Northern Ireland for Amnesty International, said the outcome of the case will have wide ranging implications.
“Women are reluctant to go to their doctors and seek help, because they see cases like this mother where she’s being prosecuted, and they’re afraid,” Teggart told CBS News. “So they stay at home, and they bleed.” A legal quagmireNorthern Ireland is part of the United Kingdom, where abortion is legal, but the U.K. law on abortion doesn’t apply there because Northern Ireland is semi-autonomous.So while women in other parts of the U.K. can get abortions at local facilities run by the tax-funded National Health Service, people in Northern Ireland have to travel, which can be financially and logistically prohibitive, or order illegal abortion pills online.Tumultuous Northern Irish politics have left the region without a functioning local government since the beginning of 2017. Since then, a United Nations committee has declared Northern Ireland’s abortion laws a “grave and systematic” breach of women’s rights. A majority of U.K. supreme court judges said Northern Irish laws were not compatible with human rights in cases of sexual crimes and fatal fetal abnormalities, though the relevant case was dismissed because of a legal technicality.”If the judicial review (of the mother’s case) is successful, it will set an important precedent and put a firm spotlight on the impact of the criminalization of women and this form of healthcare,” Teggart told CBS News. “Women who need abortions are not criminals, it’s time the law stopped treating them as such.””Don’t ask, don’t tell”It is often impossible for doctors to tell just from symptoms if a woman is having a natural miscarriage or has taken abortion pills. If a person goes to the hospital seeking care, healthcare providers will normally ask if they’ve taken medicine to determine the right course of treatment. The policy of the Royal College of Midwives, however, has been to avoid asking women in Northern Ireland whether they have taken abortion pills — to avoid being forced to tell the police if the answer is yes.”If a woman were to come into a maternity ward on a Friday night, bleeding, that could be because she was having a miscarriage, or it could be because she bought the abortion pills over the internet. You can’t ask that question though,” Tyler told CBS News.
“The first question when you see most health professionals is: Are you taking any other medication? Because you need to know what else is going on in that person’s body. So if you can’t ask the question, ‘have you taken the abortion pills,’ you don’t know whether or not she’s taken that medication, and therefore… you’re almost treating them with one big bit of information about their health and well-being missing.”The Northern Irish Department of Health’s guidance to health care providers notes that they are obliged to report illegal abortions. It also acknowledges, however, that a “health professional is unlikely to be able to tell whether a miscarriage has occurred naturally or has been caused by abortifacient drugs.”So they often don’t ask.”When we have challenged the Northern Ireland government about giving health professionals good advice about what they should do in this situation, we have basically been told, ‘just don’t ask and you won’t be told,'” Tyler said.Amnesty International says they are concerned that a criminal court date has been set for the mother before the outcome of the judicial review has been announced.
The International Triathlon Union (ITU) have announced that the elite races at the 2016 Kitzbuehel ITU Triathlon World Cup have been cancelled due to unforeseen circumstances. However, the junior races will continue as planned, and will be organised with the time-trial format that was scheduled to debut at the elite races.

“Despite our best efforts to identify a solution, in the end we were unsuccessful. Therefore, we believe that it is in the best interest of all to cancel this year’s World Cup race as soon as possible to allow for Federations and athletes to change their race and travel plans. We do apologize for any inconvenience this causes, and hope to return as a host of ITU races in the future,” said Event Director Herwig Grabner.
“We are disappointed we will not be able to contest the World Cup race in Kitzbuehel this year, a city that has a storied history of hosting successful of ITU events. However, we remain committed to debuting new formats and will therefore introduce the time-trial format in the junior race so that we can explore how this format could be incorporated in future events,” said ITU President and IOC Member Marisol Casado.

Dark chocolate has similar performance benefits to beetroot and can give you an extra edge in your fitness training scientists from Kingston University have discovered.

“Beetroot juice is rich in nitrates, which are converted to nitric oxide in the body. This dilates blood vessels and reduces oxygen consumption – allowing athletes to go further for longer,” explained postgraduate research student Rishikesh Kankesh Patel
The Kingston University team wanted to find out whether dark chocolate could provide a similar boost, as it contains a substance called epicatechin – a type of flavanol found in the cacao bean, that also increases nitric oxide production in the body.
After undergoing initial fitness tests to establish a baseline for comparison, a group of nine amateur cyclists were then split into two groups. The first group was asked to replace one of its normal daily snacks with 40g of a dark chocolate known to be rich in flavanols for a fortnight, while the other participants substituted 40g of white chocolate for one of their daily snacks as a control.
The effects of the athletes’ daily chocolate consumption were then measured in a series of cycling exercise tests in the sports performance laboratory. The cyclists’ heart rates and oxygen consumption levels were measured during moderate exercise and in time trials. After a seven-day interval, the groups then switched chocolate types and the two-week trial and subsequent exercise tests were repeated.
The study, which has now been published in the Journal of the International Society of Sports Nutrition, found that after eating dark chocolate, the riders used less oxygen when cycling at a moderate pace and also covered more distance in a two-minute flat-out time trial.
Mr Patel said the results opened the door for more research which could eventually lead to dark chocolate becoming a staple part of endurance athletes’ diets.
“Both dark chocolate and beetroot juice are known to increase nitric oxide, which is the major mechanism we believe is behind these results,” Patel said. “We found that people could effectively exercise for longer after eating dark chocolate –something that’s not been established before in this way.”
“We want to see whether the boost in performance is a short term effect – you eat a bar and within a day it works – or whether it takes slightly longer, which is what the initial research is showing,” Mr Patel said. “We are also investigating the optimal level of flavanols. At the moment there is not a lot of consistency in flavanol levels in commercially-available chocolate. Once we’ve found the optimal chocolate dose and duration, we’ll compare its effects to those of beetroot juice, and also test the influence of combining consumption of both, as they produce an increase in nitric oxide in slightly different ways.”
Sport analysis lecturer James Brouner, who is an ultra-distance runner in his spare time, said that the research suggested dark chocolate could offer particular benefits to endurance athletes.
“From a performance perspective, making an athlete more efficient can have major advantages in long duration steady-state exercise,” he said. “With so many athletes consuming beetroot juice to achieve this gain but complaining of the palatability, dark chocolate could have a similar effect but with the additional benefit of tasting good too.
“When performing endurance-based activity, being as economical as possible in energy provision is key to enhancing your performance. From our results, the consumption of dark chocolate has altered the participants’ response to the activity and therefore could enhance their endurance performance.”
Some of the world’s most acclaimed nutritionists, including Louise Burke of the Australian Institute of Sport and Team Sky’s James Morton, have joined forces to formulate sports-nutrition strategies for training in Olympic year.

The authors also say there’s credible evidence that the following ergogenic aids improve strength and stamina: caffeine, creatine, sodium bicarbonate, beta-alanine and nitrates. The team highlights the emergence of vitamin D, too, showing that the science suggesting that vitamin D encourages muscle regeneration does add up.
Finally, the team looks at compounds such as epicatechin, nicotinamide riboside, resveratrol, beta-hydroxy beta-methylbutyrate, phosphatidic acid and ursolic acid that may also promote skeletal muscle adaptations to endurance and strength training, though studies of these compounds have largely been limited to rats.

Benefits of organic meet
It’s official: organic meat is better for you than non-organic. A team of 25 researchers undertook a meta-analysis examining how nutritional content varied between organic and non-organic red meats. Though the evidence wasn’t strong enough to verify differences in antioxidant and mineral content, it did show that organic meat contains 47% more omega-3 than the non-organic alternative. This is good news for triathletes, because this polyunsaturated fatty acid has been proven to improve recovery, reduce muscle soreness after exercise and even increase fat metabolism.
Beetroot
First it was claimed that beetroot (rich in nitrates) sent endurance through the roof, then it was labelled a memory enhancer. Now nitrates have been shown to improve neuromuscular function. A study from Ohio, USA, assessed isometric and dynamic contractions in 14 resistance-trained athletes before and after three days of nitrate supplementation. The nitrate hit resulted in higher mean peak electromyography amplitudes: electrical signals travelled that bit faster. So nitrate supplementation could enhance muscle activation, leading to greater power and speed.

WTS Gold Coast victor and current leader of the WTS rankings, Britain’s Helen Jenkins, won’t be competing but her Rio team mates Non Stanford and Vicky Holland will be there, along with Jodie Stimpson, whose disappointing run in Australia ruled her out of a place on the British team. Holland won her first WTS race in Cape Town last year, and Stanford has a proven winning record at the sprint distance.

Last year Holland finished ahead of Katie Zaferes (USA) and Olympic Champion, Nicola Spirig (SUI) in a thrilling tight finish exactly a year ago.
She said: “This was the race that gave me the confidence to believe I could aim for the top of the podium, it was quite a break through last year, so it’s great to be back. This year it’s a sprint rather than Olympic distance, and my first race of the season, so it’s quite different, but I’m looking forward to getting out there.”
The line up also includes Flora Duffy (BER), second on the WTS rankings thanks to her two fourth-place WTS finishes in Abu Dhabi and Gold Coast, who will be hopeful of a podium finish.
As one of the best cyclists in the field, in Gold Coast Duffy successfully led a breakaway of three away from the lead pack that allowed a healthy advantage going into the second transition zone. South Africa is a familiar setting for Duffy, as she trains down the road in Stellenbosch for much of the year, meaning Missing from the line up is Gwen Jorgensen
Full women’s start list
Meanwhile the question in the men’s race is can Mario Mola keep up his unbeatable run and make it three in a row at WTS Cape Town in South Africa this weekend? The South African city is offering up the first sprint-distance course of the season as the men vie for more valuable Olympic qualification points as they tackle a one-lap swim, five-lap bike and two-lap run.
Joining Mola is fellow Spaniard Fernando Alarza who joined Mola on the Gold Coast podium by capturing the silver in the final lap of the run. He also just missed the podium in Abu Dhabi with his fourth-place finish.
Hoping to beat Mola will be Britain’s Jonathan Brownlee, however he won’t be joined by his brother Alistair as still has not recovered from a virus and unfortunately won’t be able to defend his 2015 victory in Cape Town. Jonny will be joined by fellow Brit Adam Bowden.

Non Stanford and Vicky Holland secure spots for Rio
Although heavy storms greeted the athletes on their arrival into Cape Town, conditions were perfect for the race itself with temperatures of 20c and light winds. After her devastation at not been selected for the Olympic Games, 2014 WTS Cape Town winner Jodie Stimpson was racing purely to bolster her hopes of a strong position in the ITU series itself. Fellow Brits Vicky Holland, who won in Cape Town last year, and Non Stanford were looking to send a message to their opponents ahead of Rio having already qualified. The winner of WTS Gold Coast Helen Jenkins opted out of this race, as did current world champion Gwen Jorgensen.
As the athletes dived off the pontoon, Bermudan Flora Duffy and Carolina Routier quickly broke away from the pack, and Duffy broke away again to exit the water in a rapid 8min 55secs. Routier was unable to ride out with Duffy, who rode off solo and established almost a 30sec lead.
The rest of the ride followed the same pattern, with the chase pack not closing up any of the gap until the final 2km of the bike. Going out onto the run course 6secs in the lead, Duffy was quickly reigned in by four athletes, made up of all three Brit girls of Stimpson, Stanford and Holland as well as Anne Haug of Germany.
It then became a case of how long Duffy could hold on, having exerted herself more on the bike and not possessing the run speed of the three Brits. It was now looking like a potential 1-2-3 for the British athletes, with Haug looking to put a spanner in the works.
However it wasn’t so clear cut, as surprisingly Vicky Holland dropped off into 5th with Duffy holding 4th place going into the final 2km of the run. Non Stanford began to show her return to full fitness is nearly complete, and began to put the hammer down. Haug and Stimpson followed her every move, whilst Kirsten Kasper (USA) overtook Holland to move into 5th place. Stimpson then consolidated 2nd position, with Haug fading.
Stanford continued to pull clear and broke the tape in 59:49, whilst Stimpson held on for 2nd place and finished 7secs back. Flora Duffy capped off a remarkable performance by overtaking Haug, claiming her first podium this year after 4th place in the previous two rounds of the series.
It was Stanford’s first race of the WTS Series this year, and she expressed surprise at her victory in an interview with ITU Triathlon: “I’m not in my ideal race shape so came here to see how I’d get on, so it’s great to take the win. There’s more to come yet which is really exciting!”
Despite the disappointment of missing out on a place in the British Olympic squad, Stimpson showed immense mental strength to finish in 2nd place. She said: “I want to thank my coaches for putting up with me the last couple of weeks, as I haven’t been the most pleasant person to be around! But I will train hard and concentrate on this year’s series and try to finish as high up as I can.”
