[ti:South Africa Leads Global Research on COVID's Effect on Athletes] [by:www.houshang36.top] [00:00.00]更多听力请访问51VOA.COM [00:00.04]Organizers of the Tokyo Olympics say they will have measures [00:04.80]in place next year to limit the spread of the coronavirus. [00:11.28]The Olympics were set to take place this past summer, [00:15.68]but delayed until 2021 because of the virus. [00:22.20]Little is known about how the virus affects the long-term health [00:27.36]of individuals who were already infected, including athletes. [00:34.00]South African researchers are leading an international effort [00:38.68]to try to find answers. [00:42.32]Wenda Nel, a South African runner, has recovered from COVID-19, [00:47.88]the disease caused by the virus. [00:51.72]Nel told VOA that she is happy to be running again [00:56.84]in preparation for the Tokyo Olympics. [01:00.44]"It was about two to four weeks that I've took it very slowly with the training. [01:05.80]Checked my heart rate every training session. [01:09.12]And from there, I actually went into full program. [01:12.12]And I feel stronger...and actually fully recovered right now." [01:16.64]Martin Schwellnus is a Professor of Sport and Exercise Medicine [01:22.00]at the University of Pretoria. [01:25.48]He directs the university's Sport, [01:28.40]Exercise Medicine, and Lifestyle Institute (SEMLI). [01:33.44]Schwellnus is leading a group of scientists in setting guidelines [01:38.60]for doctors who treat athletes recovering [01:41.92]from serious respiratory infections, including the coronavirus. [01:48.76]The Sport, Exercise Medicine, and Lifestyle Institute [01:52.84]launched the international AWARE Research Study as part of this work. [01:59.88]The project includes information [02:02.52]from the COVID-19 Recovery Clinic for athletes. [02:07.96]Schwellnus says COVID-19 seems to affect many different organ systems. [02:14.76]"In the returning to sport, it could result in medical complications. [02:18.96]And to date, we don't really know what these are for COVID. [02:22.12]And so, the focus of the project is to investigate what happens in an athlete [02:26.72]when they had COVID and how does the body heal and respond." [02:30.52]The project uses an online questionnaire [02:34.52]to gather information from any person training for three hours a week [02:39.96]who had serious respiratory infections, including COVID-19. [02:47.04]Those recovering from the disease [02:49.28]can join the COVID-19 Recovery Clinic for help returning to sports. [02:56.00]Marcel Jooste is both an athlete and a medical doctor. [03:01.68]He joined the clinic after he recovered from COVID-19, [03:06.16]which he caught from a patient. [03:09.56]Jooste told VOA that he has done [03:12.60]all expected of him so that he could return to training. [03:17.56]He adds that he is required to tell doctors how he feels following physical exercise. [03:26.24]The research examines COVID-19's effect on all organ systems. [03:33.44]Early findings show that athletes who have had COVID-19 [03:38.36]find low-intensity exercise to be harder [03:42.28]and recovery time much longer than from other respiratory infections. [03:49.40]Kelly Muller is a rehabilitation specialist at the University of Pretoria's SEMLI. [03:56.64]She says evidence-based guidelines should help recovering athletes [04:02.32]to better and more safely prepare for the Olympic games. [04:07.24]"If an athlete does happen to contract COVID-19, [04:10.52]it would be really important and really valuable [04:12.92]for coaches and medical professionals to have evidence-based advice [04:18.04]to guide that athlete back to their performance in the shortest time possible." [04:23.16]For Wenda Nel and other athletes recovering from the infection, [04:28.16]the research could help them come home from Tokyo as Olympic champions.
