โยคะ 20 นาที ผลักสมองไวขึ้น

thairath130611_001ทีมนักศึกษามหาวิทยาลัยอิลลินอยส์ของสหรัฐฯ ค้นคว้าพบว่า การฝึกทำโยคะวันละ 20 นาที จะทำให้สมองไวขึ้น

พวกเขาได้พบว่า การทำโยคะนานครั้งละ 20 นาที จะทำให้ผู้เข้าร่วมสามารถทำการทดสอบความจำและการควบคุมตนเองของการทำงานของสมองที่เกี่ยวกับความสามารถในการใช้สมาธิและการรับ และเก็บรักษาข้อมูลใหม่ๆได้ดีขึ้น ผู้เข้าร่วมบางคนยังสามารถทำงานได้ผลดีกว่าการออกกำลังแบบแอโรบิกในเวลาเท่าๆกันด้วย

หัวหน้านักวิจัยกล่าวว่า “โยคะเป็นศาสตร์และวิถีชีวิตของคนอินเดียโบราณ ไม่แต่เพียงใช้การเคลื่อนไหวของร่างกายและท่าทาง หากยังใช้การควบคุมการหายใจแลการใช้สมาธิอีกด้วย”.

A 20-Minute Bout of Yoga Stimulates Brain Function Immediately After

June 5, 2013 — Researchers report that a single, 20-minute session of Hatha yoga significantly improved participants’ speed and accuracy on tests of working memory and inhibitory control, two measures of brain function associated with the ability to maintain focus and take in, retain and use new information. Participants performed significantly better immediately after the yoga practice than after moderate to vigorous aerobic exercise for the same amount of time.

The 30 study subjects were young, female, undergraduate students. The new findings appear in the Journal of Physical Activity and Health.

“Yoga is an ancient Indian science and way of life that includes not only physical movements and postures but also regulated breathing and meditation,” said Neha Gothe, who led the study while a graduate student at the University of Illinois at Urbana-Champaign. Gothe now is a professor of kinesiology, health and sport studies at Wayne State University in Detroit. “The practice involves an active attentional or mindfulness component but its potential benefits have not been thoroughly explored.”

“Yoga is becoming an increasingly popular form of exercise in the U.S. and it is imperative to systematically examine its health benefits, especially the mental health benefits that this unique mind-body form of activity may offer,” said Illinois kinesiology and community health professor Edward McAuley, who directs the Exercise Psychology Laboratory where the study was conducted.

The yoga intervention involved a 20-minute progression of seated, standing and supine yoga postures that included isometric contraction and relaxation of different muscle groups and regulated breathing. The session concluded with a meditative posture and deep breathing.

Participants also completed an aerobic exercise session where they walked or jogged on a treadmill for 20 minutes. Each subject worked out at a suitable speed and incline of the treadmill, with the goal of maintaining 60 to 70 percent of her maximum heart rate throughout the exercise session.

“This range was chosen to replicate previous findings that have shown improved cognitive performance in response to this intensity,” the researchers reported.

Gothe and her colleagues were surprised to see that participants showed more improvement in their reaction times and accuracy on cognitive tasks after yoga practice than after the aerobic exercise session, which showed no significant improvements on the working memory and inhibitory control scores.

“It appears that following yoga practice, the participants were better able to focus their mental resources, process information quickly, more accurately and also learn, hold and update pieces of information more effectively than after performing an aerobic exercise bout,” Gothe said. “The breathing and meditative exercises aim at calming the mind and body and keeping distracting thoughts away while you focus on your body, posture or breath. Maybe these processes translate beyond yoga practice when you try to perform mental tasks or day-to-day activities.”

Many factors could explain the results, Gothe said. “Enhanced self-awareness that comes with meditational exercises is just one of the possible mechanisms. Besides, meditation and breathing exercises are known to reduce anxiety and stress, which in turn can improve scores on some cognitive tests,” she said.

“We only examined the effects of a 20-minute bout of yoga and aerobic exercise in this study among female undergraduates,” McAuley said. “However, this study is extremely timely and the results will enable yoga researchers to power and design their interventions in the future. We see similar promising findings among older adults as well. Yoga research is in its nascent stages and with its increasing popularity across the globe, researchers need to adopt rigorous systematic approaches to examine not only its cognitive but also physical health benefits across the lifespan.”

The research team included U. of I. kinesiology and community health professor Charles Hillman and Michigan State University kinesiology professor Matthew Pontifex (a U. of I. alumnus).

Do-si-do: Dancing once a week could relieve the pain of arthritis

การออกกำลังกาย เช่น ชี่กง พิลาเตส โยคะ เต้นรำ สามารถลดความเจ็บปวดจากโรคข้ออักเสบได้ นอกจากนี้ยังช่วยให้เกิดความสมดุล สุขภาพจิตดี การเคลื่อนไหวคล่องตัว และสนุกกับการใช้ชีวิต

How dancing just once a week could relieve the pain of arthritis

  • Just over half of arthritis sufferers who took part in exercise programme experienced pain relief
  • Exercises included dancing, yoga and Pilates

Having a waltz around the room or enjoying a yoga class can work wonders for millions of people suffering from arthritis, say researchers.

A study found hospital-based exercise programs such as Pilates, yoga or dance fitness can relieve the pain of the disease.

American scientists studied at the effectiveness of exercise programmes run by the Hospital for Special Surgery in New York City.

They found the weekly programmes significantly improved enjoyment of life and balance, and decreased pain and the severity and frequency of falls.

Sandra Goldsmith, director of the Public and Patient Education Department at HSS said: ‘When participants were asked to report their level of pain severity, there were statistically significant reductions in pain from pre- to post-test.

‘Pain is a huge factor in quality of life. If we can offer classes that help to reduce pain, that is a good thing.’

Researchers evaluated the effectiveness of the exercise programs, which included weekly classes of Tai Chi, yoga, mat and chair Pilates and dance fitness on 200 participants.

Surveys were administered before and after the exercise which included measures of self-reported pain, balance, falls and level of physical activity.

A pain intensity scale was used to quantify intensity of muscle or joint pain.

The team also measured pain interference on aspects of quality of life, including general activity, mood, walking ability, sleep, work, and enjoyment of life.

Roughly 53 per cent indicated that they experienced pain relief as a result of participating.

There was a 54 per cent improvement in general activity, mood, walking ability, sleep, normal work, and enjoyment of life.

Fewer respondents reported falling from pre- to post-test and fewer sustained injuries that required hospitalisation.

Dr Linda Russell, a rheumatologist, points out that the classes are low cost for patients.

‘We like to get all of our patients involved in exercise.

‘Patients benefit from supervised exercise programmes with regard to their overall sense of well-being and pain due to their arthritis.’

Osteoarthritis is a leading cause of disability in the UK, affecting around 8.5million adults.

Weight has a large influence on the prevalence of arthritis with nearly 30 per cent of obese adults suffering.

The latest study was presented at the recent American College of Rheumatology/Association of Rheumatology Health Professionals annual meeting.

ให้เล่นโยคะตอนพักงานกลางวันคลายเครียดและทุเลาปวดหลัง

หากว่ารู้สึกเครียดเพราะการงาน ควรจะหาโอกาสฝึกโยคะช่วงพักกลางวันดูบ้าง พอจะช่วยได้ เพราะมีการศึกษาที่อังกฤษพบว่า การเล่นโยคะในที่ทำงาน ช่วยคลายเครียดและทุเลาอาการปวดหลังลงได้

นักวิจัยมหาวิทยาลัยแบนเกอร์ ที่แคว้นนอร์ธ เซลส์ ได้ศึกษากับกลุ่มข้าราชการหญิงชายเมืองน้ำชา วัยระหว่าง 25-64 ปี ที่พากันบ่นว่าเครียดและปวดหลังรบกวน โดยชวนพวกเขาหันมาเล่นโยคะ นาน 2 เดือน

เมื่อครบกำหนด กลุ่มที่เล่นโยคะมีเหลือเพียง 4 คนเท่านั้นที่ยังบ่นว่าปวดหลังอยู่ ในขณะที่พวกที่ไม่เล่นยังปวดหลังอยู่มากถึง 13 คน นอกจากนั้น พวกนักโยคะยังแจ้งว่าอาการปวดหลัง และความรู้สึกเศร้าซึมก็ลดน้อยลง

อย่างไรก็ตาม นักวิจัยยังรู้สึกว่าผู้ที่เข้าร่วมการศึกษาส่วนใหญ่เป็นผู้หญิง จึงยังไม่อาจบอกได้ว่า หากเป็นผู้ชายจะได้ผลแบบเดียวกันหรือไม่.

Yoga at work may relieve stress and back pain

Published October 09, 2012

MyHealthNewsDaily

If you’re stressed at work, a little yoga on your lunch break might just help.
A new study from the United Kingdom suggests yoga done at work can reduce stress levels and lower back pain.

The study involved 74 British government workers ages 25 to 64 who said they experienced stress and back pain that was somewhat bothersome. Participants were randomly assigned to practice either eight weeks of yoga, or no yoga.

People in the yoga group took part in a 50-minute yoga class once a week, either at lunchtime or after work. They could also practice yoga at home twice a week for 20 minutes using a DVD.

All participants completed questionnaires designed to assess back pain, stress levels and overall well-being.

At the beginning of the study, 10 people in the yoga group and eight in the control group said they had back pain. At the end of the study, just four participants in the yoga group reported back pain, compared to 13 in the control group.

In addition, participants in the yoga group had reported lower levels of stress and less sadness at the study’s end, compared with those in the control group.

The findings agree with previous research showing that yoga can reduce stress levels and back pain.

The researchers, from the Bangor University in North Wales, noted that the majority of participants were women, so the findings may not apply to men. Also, the benefits in the yoga group may have been influenced by the placebo effect — the idea that a treatment is beneficial simply because patients believe it will work.

Future studies should examine whether yoga at work can reduce the number of sick days workers take, the researchers said.

“Integrating yoga into the workplace, at lunchtime or after work, may provide a time-effective, convenient and practical method for reducing the costly effects of stress and back pain,” the researchers wrote in the Sept. 25 issue of the journal Occupational Medicine.
