Adarq.org

Yeah. I'm thinking about writing an article around that article and other one's saying similar things. Something about training specificity regarding the type of muscular contraction.

nice..

study 12 is very nice.. never seen that one.

awesome.. great studies

these studies really apply to what I am currently doing from jun-aug... so it should be very interesting to see how all of this will apply.

peace & thanks man good stuff.

My only goal in life is to dunk.

Not to score? 

I can get that anytime. Not dunking though. Lol.


On a side note, why the hell is there a kiss smiley thing haha. Hey adarqui,     

nice.. i should make all of the emoticons pictures of my phase doing the emoticon........................

would be kind of epic.

bench press and coordination tasks somehow stayed the same though..

"Decrements in performance during SUSOPS are primarily restricted to tasks that recruit muscles that are over-utilized without adequate recovery.".. so maybe they didn't fatigue their chest/tricep muscles too much, and bench didn't go down.

you would think that one would obviously go down with how much lean mass/fat mass/sleep deprivation they lost.


if bench didnt go down and they lost all that mass, they just increased relative strength bigtime

peace

nah, those studies are just showing you that reaction time/performance etc is not as effected by sleep deprivation as we might think.. and when you factor caffiene into the equation, performance level can be near optimal.

as for #7, it's saying that taking a nap could decrease the effect of only having 4 hours sleep.

it's never good to not sleep at all when you have a performance test/event the day after... but, if you are somehow unable to sleep, just have the confidence that a shitload of caffeine will help you perform at near optimal levels


edit: i mean how many times have you been so excited about the next day, that your sleep suffers? it's great to know that you can still perform... it happens to me every time I have something big planned the next day, like trying to for some PR dunks.. once I started telling myself "it doesn't matter if i sleep or not, i'll still jump good", it got out of my head... and studies like this have only help me sleep better because I stop worrying about it alot of these studies are from my huge notes file hehe..

peace

Effects of Exercise, Bedrest and Napping on Performance Decrement During 40 Hours

Young male Naval volunteers were denied normal noclurnal sleep and maintained on a 60-min lreatment-160-min testing schedule during 40 consecutive hrs. Ten subjects bicycled, 20 subjects controlled EEG activity during bedrest, and 10 subjects napped. Eight measures of addition, auditory vigilance, mood, and oral temperature were obtained. The Bedrest group showed significant impairment on all eight measures, and thus, gave no support to lite forced-rest theory of sleep function. The Exercise group was worse than the Nap and Bedrest groups for all measures. In spite of fragmented, reduced sleep (about 3.7 hrs per 24 hrs), the Nap group had no impairment on six of the measures. The results suggest that exercise increases the impairment due to sleep loss, and naps reduce or remove this impairment. Bedrest is not a substitute for sleep.






Sleep-dependent learning: a nap is as good as a night

The learning of perceptual skills has been shown in some cases to depend on the plasticity of the visual cortex1 and to require post-training nocturnal sleep2. We now report that sleep-dependent learning of a texture discrimination task can be accomplished in humans by brief (60? 90 min) naps containing both slow-wave sleep (SWS) and rapid eye movement (REM) sleep. This nap-dependent learning closely resembled that previously reported for an 8-h night of sleep in terms of magnitude, sleep-stage dependency and retinotopic specificity, and it was additive to subsequent sleep-dependent improvement, such that performance over 24 h showed as much learning as is normally seen after twice that length of time. Thus, from the perspective of behavioral improvement, a nap is as good as a night of sleep for learning on this perceptual task.




Impact of Ramadan on physical performance in professional soccer players

ABSTRACT

Objective: Ramadan is a period of daylight abstention from liquid or solid nutrients. As sports continue to be scheduled, an understanding of the effects of Ramadan on Muslim athletes is warranted.

Design: Two Algerian professional soccer teams (55 men) were studied. Field tests of physical and soccer performance were collected before, at the end and 2 weeks after Ramadan in 2004. Players were queried on sleeping habits and personal perception of training and match performance.

Setting: Field setting at club training ground.

Main outcome measures: Performance on fitness and skill tests.

Results: Performance declined significantly (p<0.05) for speed, agility, dribbling speed and endurance, and most stayed low after the conclusion of Ramadan. Nearly 70% of the players thought that their training and performance were adversely affected during the fast.

Conclusions: The phase shift of food intake and disruption of sleep patterns affect actual and perceived physical performance. Islamic athletes need to explore strategies that will maximise performance during Ramadan.
