A study of university rugby players has shown that they are more likely to experience an inhalation of sleep disorders than an average middle-aged man.
The study also showed that the athletes who are experiencing this problem are also more likely to have low levels of oxygen in their blood and higher pulse rates during the night, suggesting that athletes could breathe sleep disorders be at risk of heart abnormalities.
The researchers say that this study could indicate that breathing of sleep disorders is a factor in the phenomenon of young athletes that seem healthy that die from a sudden and unknown heart attack.
Inhalation of sleep disorders (SDB) is characterized by unusual breathing patterns or respiratory breaks during sleeping, ranging from sleeping apnea, where the respiratory paths are completely closed or partially Many during sleeping. Having a high BMI, over 40 years of age and having a large throat circumference is some of the common factors associated with SDB. If it is not treated, patients with SDB-related conditions are at an increasing risk of developing chronic diseases such as cardiovascular disease, heart failure and type 2 diabetes.
The study, published in ERJ Open Research, led by Yoshitaka Iso, a Cardiologist and Associate Professor at the University of the Sports and Exercise Show Research Institute, Yokohama, Japan. He explained: "We wanted to investigate the frequency of respiratory sleeping in conflict sports athletes, such as rugby or American style players, because we know that they usually get higher BMI and throat circumference than athletes of other sports.
"We tend to assume that young, competitive athletes will not suffer conditions such as SDB, which are more prevalent in people with higher BMI and inactive lifestyles, but more research is needed to determine what might be contribute to sudden heart death in athletes, and SDB is a good candidate for this because it can affect the normal functions of the heart. "
The study included 42 male rugby players aged between 18 and 19. A special device was used to monitor overnight changes in the rhythm of athletes, heartbeat and heart rate, oxygen levels of the blood, the number of times they began to wake up, and how long they were awake.
The data showed that 18 (43%) of athletes met the criteria for SDB, which meant they were experiencing five or more breathing breaks that lasted for at least 10 second, over a total sleeping time of more than three hours.
The data also showed that athletes with SDB had higher average heart rates and lower levels of oxygen in their blood than athletes who did not have SDB. They also experienced more periods when their oxygen levels in the blood were unusually low.
Professor Iso and the team assessed all the young person's heart and lung performance in rest and during exercise, to check for and without cardiovascular abnormalities with athletes with and without SDB. These tests showed that heart rate rates were higher among SDB athletes, and that SDB athletes were experiencing more cases of additional or disruptive heartbeat than non-SDB athletes, suggesting further that SDB could be associated with abnormalities. r galon.
Professor Iso said: "We observed the breathing of sleep disorders in 43% of the young athletes we assessed. This is a higher rate than we expected, and it's still higher than & # 39; r SDB levels reported among middle-aged men of the general population of the United States and Europe. Our data also showed that many potential warning signs, such as effects on athletic breathing and heart rates, often occur among athletes with SDB .
"Although it has not been found that the athletes in this study have yet serious conditions, similar to their young age, we do not know how their time can get worse in the future due to associated cardiovascular results. SDB connection and abnormal heart functions we have observed in this group, we guess that SDB could be a potential factor in the unknown deaths of some young sports sports athletes, as it seems very common but on Currently it's not screened regularly. "
Professor Anita Simonds is a Consultant in Respiratory Medicine and Sleeper at the Brompton and Harefield Royal Breathe Trust, UK and the European Incubation Association of Elections, and was not part of the research. He said: "It's too early to close that breathing of sleep disorders is a definite factor in the sudden death of athletes in the heart, but these results provide food to think about the ways in which disorders breathing affects the health of young athletes, fit.
"In this study, the overall level of breathing of sleep disorders was mild, but the results point out that a sleep study should be considered to assess the presence of respiratory sleep disorders in caring for collision sports athletes, such as rugby or American style players, as it could help identify those at risk of cardiovascular complications. "
The researchers say that there is a need for additional big studies to confirm their results and determine the basic mechanisms that lead to SDB, and indicate that the study limit is that only one night SDB was assessed.
