What do you think are the major advantages that aerobic training offers over intervals? The articles I have seen comparing intervals to aerobic exercise are generally heavily in favor of intervals. Do you training aerobically because you think it will have more carryover to tennis or another goal you have?

answer won't be as good/detailed as adarqs but for me

aerobic - weightlifing are on completely different ends of the energy system spectrum, so you could do run 30 mins + lift the next day without real detrimental effects from the running. anaerobic(interval)-weightlifting - much closer on the energy system spectrum, lots of overlap so intervals may mess with recovery from lifting/performance next day etc. this is just from my perspective as someone focusing on weightlifting though....for sports performance the interval type stuff is much more important. + this isn't adarqs reason either.

also i think adarq focusses on aerobic because - his main focus is a (largely) aerobic event? (5k). although i have noticed a lot of 5k sort of running 'programs' suggest a bit more interval stuff than i see you do - is this because you feel your speed/lactate threshold fitness is stronger than your aerobic base anyway?

minimal, zero drop but with some cushioning. vibram soles too - so they'll last.

they do a trail version too

Metabolic and hormonal effects of ‘catch-up’ sleep in men with chronic, repetitive, lifestyle-driven sleep restriction

Quote
"Results

Insulin sensitivity was higher following three nights of sleep extension compared to sustained sleep restriction. Fasting insulin, c-peptide, HOMA-IR, HOMA-β, leptin and PYY decreased with ‘catch-up’ sleep, QUICKI and testosterone increased, while morning cortisol and LH did not change. Targeted acoustic stimuli reduced SWS by 23%, but did not alter insulin sensitivity.

Conclusions

Three nights of ‘catch-up’ sleep improved insulin sensitivity in men with chronic, repetitive sleep restriction. Methods to improve metabolic health by optimizing sleep are plausible."

Jeopardizing Christmas: Why spoiled kids and a tight schedule could make Santa Claus fall?

Abstract
Quote
Santa Claus’ spatio-temporal gait characteristics, ground reaction forces during treadmill walking as well as postural sway during loaded, unloaded and cognitive interference tasks were examined in order to estimate his fall risk.

Seventeen healthy males, disguised as researchers and students (age: 30 ± 10 years; height: 179 ± 6 years; weight: 76 ± 7 kg; BMI: 24 ± 2 kg/m2; physical activity: 12 ± 4 h/week) and who still believe in Santa Claus randomly underwent balance and gait analyses with and without cognitive interference. The conditions were to be dressed as “Santa Claus” (wearing costume consisting of a beard, cap, robe, heavy sack with a load of 20 kg) or dressed in “normal clothing” (no costume). Spatiotemporal gait parameters (walking velocity, gait variability and stride time, length and width), ground reaction forces (GRF) (left- and right-sided heel strike and push off) and postural sway (30 s tandem stance on a force plate) were measured.

“Santa-effects” (0.001 < p < 0.05;  ) and “Dual-task effects” (0.001 < p < 0.003;  ) were found for postural sway (increased sway), GRF (decreased forces for dual tasking, increased forces for the Santa condition) and the majority of spatio-temporal gait parameters. Significant “Santa” × “Dual-Task” interaction effects were not observed (0.001 < p < 0.05;  ). Relevant leg effects of GRF during walking were not found.

Santa Claus faces a tremendously increased risk of falling when carrying his Christmas sack with 20 kg of presents. Cognitive loads also impair his neuromuscular performance. It is recommended that Santa trains his strength and balance before Christmas and also to avoid filling his sack with more than 20 kg of presents. Also, cognitive training may help to improve his dual task performance.

Prolonged Superficial Local Cryotherapy Attenuates Microcirculatory Impairment, Regional Inflammation, and Muscle Necrosis After Closed Soft Tissue Injury in Rats

Quote
Background: Closed soft tissue injury induces progressive microvascular dysfunction and regional inflammation. The authors tested the hypothesis that adverse trauma-induced effects can be reduced by local cooling. While superficial cooling reduces swelling, pain, and cellular oxygen demand, the effects of cryotherapy on posttraumatic microcirculation are incompletely understood.

Study Design: Controlled laboratory study.

Methods: After a standardized closed soft tissue injury to the left tibial compartment, male rats were randomly subjected to percutaneous perfusion for 6 hours with 0.9% NaCL (controls; room temperature) or cold NaCL (cryotherapy; 8° C) (n = 7 per group). Uninjured rats served as shams (n = 7). Microcirculatory changes and leukocyte adherence were determined by intravital microscopy. Intramuscular pressure was measured, and invasion of granulocytes and macrophages was assessed by immunohistochemistry. Edema and tissue damage was quantified by gravimetry and decreased desmin staining.

Results: Closed soft tissue injury significantly decreased functional capillary density (240 ± 12 cm−1); increased microvascular permeability (0.75 ± 0.03), endothelial leukocyte adherence (995 ± 77/cm²), granulocyte (182.0 ± 25.5/mm²) and macrophage infiltration, edema formation, and myonecrosis (ratio: 2.95 ± 0.45) within the left extensor digitorum longus muscle. Cryotherapy for 6 hours significantly restored diminished functional capillary density (393 ± 35), markedly decreased elevated intramuscular pressure, reduced the number of adhering (462 ± 188/cm²) and invading granulocytes (119 ± 28), and attenuated tissue damage (ratio: 1.7 ± 0.17).

Conclusion: The hypothesis that prolonged cooling reduces posttraumatic microvascular dysfunction, inflammation, and structural impairment was confirmed.

Clinical Relevance: These results may have therapeutic implications as cryotherapy after closed soft tissue injury is a valuable therapeutic approach to improve nutritive perfusion and attenuate leukocyte-mediated tissue destruction. The risk for evolving compartment syndrome may be reduced, thereby preventing further irreversible aggravation.

The Use of Ice in the Treatment of Acute Soft-Tissue Injury
A Systematic Review of Randomized Controlled Trials

Conclusion

Quote
Many more high-quality studies are needed to ensure that clinicians and sportsmen are following evidence-based guidelines in the treatment of acute soft-tissue injuries. Primarily, these must focus on developing modes, durations, and frequencies of ice application, which will optimize cryotherapy during immediate and rehabilitative care. Similarly, an optimal mode and duration of compression treatment must be highlighted. This evidence will highlight the respective value of each individual modality and if appropriate provide the basis of an optimal method for treatment combination.

some support for icing in here, although a lot of it comes down to 'icing succesfully reduced inflammation'. well yeah, but is that desirable anyway? interestingly a few comments on icing resulting in analgesia allowing earlier/more aggressive exercise + better healing.

100 miles on a track................ WTF?!?!?!?!?!  :o

impressive, but insane.. wow

with a bunch of other people also which must have been super annoying having to run around them all the time - surely would have been faster if not for that!

fasting = higher circulating catecholamines/cortisol so improved performance via that pathway/more mental focus as well as being physically lighter. i remember doing some 36/48h fasting experiments and my appetite completely dropped off after a day without food and it was really hard to sleep not because of hunger but because of being 'wired' without touching a stimulant. also any stims might have a greater effect when fasted? (don't forget caffeine for peaking!) i've been intermittent fasting for a few years now and do the majority of studying fasted, focus is so much better.

in regards to stretching hip flexors before jumping - surely you cannot avoid stretching the rec fem which is a 'quad' and a 'hip flexor' and if static stretching reduces peak power output, is it wise to stretch 'hip flexors' (of which one is a knee extensor) before attempting maximal vj?
perhaps a period of time between stretching and jumping sufficient to still have the greater hip extension from the stretching but not the reduced power output? i have no idea what kind of time this would be.

Injury, Prehab, & Rehab talk for the brittlebros / Re: Icing
« on: December 23, 2015, 08:50:32 pm »

I never iced. It felt terrible too. When i had patellar tendonitis, i felt like icing made my knee brittle and stiff and it would cause WAY more pain when i moved after that. After rolling an ankle, same thing. I prefer to keep the injured joint mobilized. Ill move it around in a ROM just under a pain threshold, and keeping that up will slowly increase the ROM pain-free. Walk it out to some extent. Depends on what the problem specifically is. I found that to be more effective. Icing always felt... "Anti-ROM," if you will.

As for NSAIDS post surgery... Well, the idea of that is to lessen pain, not necessarily to speed healing. I have a similar approach when im sick. Your body's symptoms are a way of getting rid of the sickness! When you cough its stripping off a small microscopic lining from your throat that hopefully contains bacteria/virus/whatevee so that its expelled. When you have a stuffy nose its because your body made more mucous to block more bacteria from entering your body as your immune system is weakened. When you have a fever its so that the proteins in the virus you have denature and thus the virolus doesnt perform properly and cant reproduce. Your symptoms arent the problem -- they are there to help solve/get rid of the actual problem, which is the bacteria/virus/etc.

So treating the symptoms isnt treating the cause of the problem. And at times it makes the true problem worse. However, sometimes it IS beneficial to treat the symptom; if youre in so much pain you cant sleep, take a pill. Sleeping is good for recovery, plus "feeling" better and positivity has been shown to let us get over sicknesses faster. If your throat stings so much from coughing that your causing more harm than good, than yeah take a numbing spray to the back of the throat. If your fever is so high that its starting to get dangerous, then yeah lower that fever.

The point is to attack the source of the problem wheb possible, and only treat the symptoms when necessary and/or beneficial to do so. This applies to sickness, surgery, and injuries.

Yeah - movement seem's to be the best way to go about these things...not just in terms of not getting 'stiff' but in terms of pumping waste out and nutrients etc in. I iced my knees constantly when i was playing basketball - they never got better, not until i stopped playing and started lifting more and icing less.

obviously the NSAIDs are used for pain relief not just inflamm but for example my sister just had a tonsillectomy, she had codeine, paracetamol + ibuprofen. how much difference does the ibuprofen make to pain when taking codeine/paracetamol idk. nobody ever says 'if you take this you might heal a bit slower so if you can deal with the pain and wanna heal quicker dont take it'. i guess the evidence isn't there to say how long it might prolong healing.

does this mean heat is advantageous to areas with active inflammation going on? i gather for long term 'tendinosis' type stuff its good now. how about things like bursitis rather than tendonitis - would ice be beneficial here to limit the inflammation when there isn't so much structural damage that needs healing? does it render contract showers/ice baths useless or is this more of a cns thing? this stuff is still used at the highest levels in sport. RICE is still taught in med school (so much for evidence based medicine). I guess it's another case of finding what works for you, i'm sure people on here still swear by icing.

http://physicaltherapyweb.com/paradigm-shifts-use-ice-nsaids-post-acute-soft-tissue-injuries-part-1-2/


I still use and see other people recommending icing for injuries - both acute and chronic, but reading up it seems it may not have been the best thing. Same goes for NSAID use. Also wondered, if nsaids inhibit healing so much - surely they are terrible for post surgical pain relief?

What everyone's views on icing? Do you use it?
