Stanford sleep study performed with Women's tennis team shows Amazing results. More sleep you get, Better the performance in the Matches. Here is the article.

The amount of sleep an athlete gets appears to have a large impact on sports performance.

Cheri Mah of the Stanford Sleep Disorders Clinic and Research Laboratory has been following the sleep patterns and athletic performance of Stanford athletes for years. Her research continues to show that getting more sleep leads to better sports performance for all types of athletes.

One study she authored, published in 2009, followed the Stanford University women's tennis team for five weeks as they attempted to get 10 hours of sleep each night. Those who increased their sleep time ran faster sprints and hit more accurate tennis shots than while getting their usual amount of sleep.

In earlier studies, Mah found that getting extra sleep over several weeks improved performance, mood and alertness for athletes on the Stanford men's and women's swim teams and men's basketball team.

Mah's research is some of the first to specifically look at the impact of extra hours of sleep on athletic performance and suggests that sleep is a significant factor in achieving peak athletic performance.

This is particularly important for collegiate and professional athletes who have full schedules and often travel for games and competitions. Athletes can easily fail to get regular, consistent hours of sleep. This lack of sleep, or "sleep debt," appears to have a negative effect on sports performance, as well as cognitive function, mood, and reaction time. Much of this can be avoided by making regular sleep as much of a priority for athletes as practicing their sport and eating right.

According to Mah, many of the athletes have set new personal bests and broken long-standing records while participating in these studies. Based upon her studies, many Stanford coaches have made changes to practice and travel schedules to accommodate the athlete's need for more sleep. For many athletes and coaches, this 2009 study was the first body of research that helped them truly understood how large of an impact sleep can have on performance and results.

Why More Sleep May Improve Sports Performance
Researchers speculate that deep sleep helps improve athletic performance because this is the time when growth hormone is released. Growth hormone stimulates muscle growth and repair, bone building and fat burning, and helps athletes recover. Studies show that sleep deprivation slows the release of growth hormone. Sleep is also necessary for learning a new skill, so this phase of sleep may be critical for some athletes.
How Much Sleep Do You Need?
Research shows that as little as 20 hours of sleep deprivation can have a negative impact on sports performance, particularly for power and skill sports.
Sleep experts recommend seven to nine hours of daily sleep for adults, and nine to ten hours for adolescents and teens. You can estimate your own needs by experimenting over a few weeks. If you fall asleep within 20 minutes of going to bed and wake up without an alarm, you are probably getting the right amount of sleep. If you fall asleep immediately upon hitting the pillow and always need an alarm to wake up, you are probably sleep deprived.

The good news for most recreational athletes is that just one sleepless night is not necessarily associated with any negative effects on performance. So, don't worry if you toss and turn the night before a big competition. One sleepless night is unlikely to hurt your performance.

How to Use Sleep to Improve Sports Performance
•Make sleep a priority in your training schedule.
•Increase your sleep time several weeks before a major competition.
•Go to bed and wake up at the same times every day.
•Take daily naps if you don't get enough sleep each night.

This is the KEY statement:

One study she authored, published in 2009, followed the Stanford University women's tennis team for five weeks as they attempted to get 10 hours of sleep each night. Those who increased their sleep time ran faster sprints and hit more accurate tennis shots than while getting their usual amount of sleep.


So get at least 10 hours of sleep each night, if you want to perform your best. Also another critical fact is that you can't just catch up day before the match by sleeping alot night before.
 
If this is what Stanford uses its sleep lab for, maybe it's time to shut it down. This is bad and potentially harmful research, as it doesn't address the findings of Kripke (at UCSD) and others demonstrating that 6.5 to 7.5 hours of sleep is associated with opitmal longevity, with sleep duration of 8 or 9 hours (or longer) being associated with shorter longevity. (These are associations, and it's not known as yet whether there is a cause-effect relationship, but it is possible). Sleeping longer lets you hit a tennis ball better? Wonderful. But what are the implications for health and longevity?

Who gives the DAng,,,,it it will help you win your next USTA league match ??????? that's what matters,,,right ?
Besides, if i only sleep, 6 hours, i feel like i have trouble thinking.

Excellent point. I mean the population Kripke studied (women in their late 60-70s) is pretty much identical to college age elite athletes. It's completely logical to assume the findings would translate.
 
If it's any Consolation, large studies by Metropolitan Life Insurance Co. years ago found the same thing -- even in younger adults, 7 hours seems to be the optimal amount of sleep for longevity (something insurance companies have a keen interest in.)

I am 31 and 6-7 hrs of sleep is more than enough for me.

When I was in my late teens, I had to sleep for at least 9 hrs to feel refreshed.

In my early 20s, 8 hrs.

In my late 20s, 7 hrs.

I don't see a conflict between the Stanford study and the UCSD study. Both are consistent with current views on sleep.

Of course that was self-selected sleep. And the people that slept less also had higher rates of employment, medical insurance, were more likely to be married and have kids. All of those factors also increase life expectancy, but it was probably the sleep thing.

The Kripke link was a bit our of nowhere, maybe you're a student who took one of his classes? I haven't talked to him in about a decade, but I bet he'd get a kick out of his work being mis-used like this on an internet forum.

why don't you sleep 5 hours and play a match and sleep 10 hours and play a match. and see which day you play better

Why would I assume this study is wrong and the previous one correct?

In Spadea's book he says he cant play at his best unless he gets at least 10 hours sleep per night.

I try to live my life according to Spadea's teachings as much as possible.
 
Just saw something about this on tv this morning. Don't remember who but some guy studying this said 7-9 hrs is best. The main point he made is that excess sleep is usually a symptom of some underlying problem and that is why excessive sleep is bad but, not bad for you...it doesn't cause anything, its a sign that something is already wrong.
 
It's also individual.

Each person has a set amount of sleep that is ideal for them. Most people's sleep cycle is 90 minutes long (this changes at different times in life, which is why ideal sleep duration changes), and the total amount of sleep that is best for them will be some multiple of that.

A majority of people are 7.5 hour sleepers, which is where the '8 hour' recommendation comes from when you add in some time to fall asleep. There are lots of 9, and some 10.5 hour sleepers. There are also some 6, 4.5 and even a few 3 hour sleepers.

In graduate school I got to work with a woman who was a true 2 cycle sleeper. She was in her 50s at the time, married and had 3 grown children. She had happily lived almost 2 whole lives, her regular life, and a second when the rest of her family was still sleeping.

LMAO. It's the INSURANCE companies they have crap research. Those are correlational studies people. It's entirely possible that for example sickly people tended to stay home alot not - not have a career and sleep extra. And healthy people had a demanding job and worked longer hours. Or that healthy people COULD work longer hours with little ill effects and the additonal money they made outweighed there urge to sleep. The list goes on and on. Who knows..its correlational!

The study does not prove anything with regards to the fact that sleeping more makes people die sooner. <g>. What's next you guys are going to complain that high ice cream sales makes the weather hot? Haha.

This study on the other hand is objective proof that more sleep improves performance. For all we know the "7 hour" sleepers in the insurance study would have lived longer and done even better while at work - but because it's not a real experiment (just a correlational study) we will never know.

What we would have to do is make a selected group of people sleep extra and then see the results of that through their entire life. If its a self selecting group all bets are off. Well that ain't going to happen. That doesn't mean though sleep more kills you. <g>

It's like the idea that diet soda makes you fat (which was recently disproven - or at least proven to be more dubious).. What if FAT people drink diet soda? What if people with diabetes are trying to cut their sugar intake..

Well it turns out that seems to be the likely case - not that diet soda makes you fat..But I digress. Correlation studies are not good science. You can conclude all kinds of whacky things with them that turn out not to be true at all. It's science 101.

We could conclude that ice cream sales make it hot.. :p Or we can take me for example - I loved to eat marshmellow fluff sandwiches when I was a kid. Clearly marshmellow makes you a giant right? Let's not pay any attention to the genes - and the fact my Dad is 6'2" and his Dad was 6'3" and his brother was 6'6"..

The title is sooo misleading "sleep disorders" and "amazing results".

10 hours has been used by many athletes for about 30 years. I remember reading Marty Liquori's auto (he's an American Olympian middle distance runner). He slept 10 hours. IIRC, Alberto Salazar also did.

The study actually doesn't prove that sleeping more causes improved athletic peformance. What needs to be assessed is what the 7 hour sleepers did with those extra 3 waking hours compared to the 10 hour sleepers. Did they use the extra waking time to go to the gym, thus draining themselves physically and impairing their tennis performance? Did they sleep less because they were out drinking at night and it's the alcohol that impaired their performance. The study is of interest but still a correlational study that doesn't establish what facilitates better performance.
