One night of sleep deprivation decreases treadmill endurance performance
( European Journal of Applied Physiology 2009; 107: 155-161)


Pickett and Morris (1) reported that time to exhaustion (TTE) was unaltered following 30 h of sleep deprivation, whereas Martin (2) reported only a marginally (P = 0.05) significant decrease in TTE following 36 h of sleep deprivation. In addition, the effect of sleep deprivation on pacing is unknown as previous investigations used time to exhaustion rather than fixed end point tests to determine performance. The nature of these tests require that athletes exercise until exhausted, which is unlike most athletic events. For this reason, the authors of this investigation used a distance-based timed test to examine the effect of sleep deprivation on endurance performance.

This study examined the effect of one night of sleep deprivation on pre-loaded, 30 minute, self-paced endurance performance. In addition, the authors investigated how sleep deprivation effects pacing, cardiorespiratory, thermoregulatory, and perceived exertion. It was hypothesized that endurance performance would decrease following 30 hours of sleep deprivation.

In this investigation, 30 hours of sleep deprivation was shown to have a negative impact on pre-loaded endurance performance. Even though the subjects completed a shorter distance after sleep deprivation, their perception of effort (RPE) was the same in both trials. This indicates that the subjects felt like they were working just as hard in the sleep deprivation trial as they had under control conditions. Therefore, it is possible that sleep deprivation affects performance through alterations in perceived exertion.

In addition to endurance performance, the authors examined cardiorespiratory, and thermoregulatory responses to exercise. The results indicated that sleep deprivation has a limited effect on cardiorespiratory and thermoregulatory responses to exercise.


Peaking Strength:
1. Start @ 70/45 kg on the barbell and on the minute for as many minutes perform 1 squat clean; add 5kg to barbell per minute.
rest 5 min
2. Using the weight you finished with Dead Lift it on the minute for 2 reps every minute; add 10kg to barbell per minute.
rest 5 min
3. for time:
50 HSPU on parallettes

  1. Coach,

    What depth are we going to on the parallettes?

    thanks

  2. Interesting on the sleep deprivation thing. I almost commented on this subject on Monday. I had about 2 45 min naps over the previous 35 hrs when I did that training, and then didn't get to bed for another 10 hrs. When this has come up over the last few months, I have noticed I generally do better than I think I will (on that day). Sometimes PR's are set. The only think I think I can pinpoint getting worse is the wattage on short row sprints seems to "suffer". I feel ok, or normal or whatever is expected, but the wattage turns up lower regardless of my effort (or maybe perceived effort?). Anyway, just my observation.

  3. Performed on Thursday, 11/04:

    A. Bench press, 5-3-1 (+); finished with 244 for 8 reps

    +

    Three rounds for time of:
    35 double-unders
    25 push-ups
    15 CTB pull-ups

    7:30

    Struggled with, well, everything. Also, I was cleared to begin loading squats on Monday, and started a basic linear progression with 3 x 5 @ 45 lbs., plans to increase 10 lbs. twice/week.

  4. 1: 95kg
    2: 160kg
    3: 9.45 to Ab Mat, no paralettes

    Not surprising with the sleep deprivation, but good to have the confirmation.

    Task 1 completed in 7:15 (21.5# ball)

    20min break

    Task 2 completed in 1:54 (170#)

    No time for part 3 today may do tomorrow

    DU's broke at 18 on rd 2, otherwise UB (felt pretty easy...)
    Pt.2 easy also, but hard to squeeze in situps on time.

    ReplyDelete
  13. 1: 80kg, felt easy but couldn't hit 85kg
    2: 170kg, hit 175 once
    3: 6:38* Not Rxd. head to plates, about 4" shy of full ROM. PR in number of reps, happy with that.

    Deadlifts got heavy quickly towards the end, caught me by surprise.

    Hit a wall quick on both 1 and 2 today. Part 1 pulls felt really strong, the catch not so much. Did too much snatch practice yesterday. Should've rested

  16. 1. 115 (pr#1 kg.)
    2. 160
    3. 11:48 (regular, not elevated)

    Notes: happy with PR on cleans, felt good. DL felt really heavy quickly after that.

    HSPU - still a weakness, so did regular to get as many strict as possible. Kipped about 12-15 of the 50. Need lots of practice.

    3.26:53...used what I think were (about) 14" parallelettes...chin below hands every rep...very tough ROM, but I like a good challenge...first 4 UB...then singles...all strict

  34. A. 285

    B. 435

    C. 8:06 (25 ring HSPU, shoulders to rings)


    Notes:
    - Got under 295, sloppy catch
    - Called it at 435 for the sake of the back
    - No paralletts, so I used rings

    3. 8:55 no parallettes. used a couple 2 inch risers I found at the gym. Kipped the last 8 reps, all other reps were strict.

    ReplyDelete
  38. 1. 102.3 kg (225 pounds)
    2. 147.7 kg (325 pounds)
    3. 35 reps in 25:10 (5" deficit) - first 20 strict, next 15 kip.

    Progressed in 10lb jumps for cleans and 20lb jumps for deadlifts Stopped after 325 on the deads because they were getting ugly...probably going to be sore tomorrow. My speed strength > my slow strength. Ran out of time to finish the hspu's. 5 inch deficit (from top of parallettes to where head touched), p-lettes were the same distance apart as from my elbow to my fingertips. Some serious quad cramping going on during some of the more difficult reps.

    Even though I didn't get to finish, and it was slow as hell, I am stoked to be able to do hspu's that deep, and strict. A full rom strict hspu on the p-lettes is big goal for me, and I think I'm getting close.

    Hi,

    I hope all is well with you. Healthline just published an infographic detailing the effects of sleep deprivation on the body. This is an interactive chart allowing the reader to pick the side effect they want to learn more about.

    You can see the overview of the report here: http://www.healthline.com/health/sleep-deprivation/effects-on-body

    Our users have found our guide very useful and I thought it would be a great resource for your page: http://optimumperformancetraining.blogspot.com/2010/11/fri-nov-5-2010.html

    I would appreciate it if you could review our request and consider adding this visual representation of sleep deprivation to your site or sharing it on your social media feeds.

    Please let me know if you have any questions.

    All the best,
