Recovery is key to muscle growth in resistance training. New study finds soy protein supplementation blunts Testosterone response in recovery and Whey protein blunts cortisol response in recovery. Conclusion: Whey protein to blunt cortisol response in recovery will aid anabolic recovery.
There is a growing body of preclinical literature suggesting that ω-3 FAs, and DHA
in particular, may play a therapeutic role in mTBI
the
potential for ameliorating or possibly even preventing the complications associated with concussions
DHA is the predominant ω-3 FA present in the brain, and, consistent with this finding, DHA,
and not EPA, has been demonstrated to be critical for brain development and cognitive function throughout life
the concentration of EPA in the brain is negligible
(77–80), suggesting that EPA plays a limited role in mediating the beneficial effects of LCPUFA supplementation on mTBI pathology
the current state of the science regarding LCPUFA supplementation for the treatment of concussion
is based primarily on animal models
there is evidence that the amount of DHA in brain tissue is decreased after mTBI (65, 66), suggesting an elevated need for DHA in mTBI recovery.
the well-established role of DHA in supporting
the structure and function of the brain throughout the lifespan (26, 27, 46, 47, 53) provides encouragement that LCPUFAs may also prove beneficial in the context of concussion recovery.
no therapies are currently available to aid the recovery from this injury
Previously discussed reports outlining the use of ω-3 FAs in the recovery from severe
TBIs (reviewed in Ref. 92) described the use of very-high doses of LCPUFAs (16.2 g/d EPA plus DHA) in the recovery of these patients
Within
the context of mTBIs/concussions, translating a DHA intake used in several rat studies of mTBI recovery (40 mg ⋅ kg−1 ⋅ d−1 DHA) (57, 63, 64) using body surface area conversion methods (93) amounts to an estimated human intake of 387 mg/d DHA
Recovery period of Ironman triathlon associated with significantly increased inflammatory response. The vast majority is resolved by day 5 in this study, though low-grade inflammation persisted beyond day 5. Cortisol was significantly elevated and Testosterone was significantly decreased in the early recovery period. Muscle damage and significant inflammation is a prominent finding in the recovery phase of a triathlon.
only abstract available here. Carbs, particularly high glycemic cars are helpful in recovery. Carbs in the recovery are ket to restoration of muscle glycogen. Immediate supplementation aids glycogen restorations compared to > 2 hours. At 24 hours, there is no difference between early < 2h and delayed >2h; peak glycogen occurs at 24 h in this study.
Wrist and forearm splints may be suggested for people with weak wrists or for those that have been previously injured, for tendonitis wrist support and even as a preventative for those who awaken in the morning with pain or numbness after sleeping on their hands at night. The best orthopedic wrist braces for carpal tunnel syndrome, occupational stabilization and relief from the pain of wrist strains and sprains. This Right hand wrist and forearm splint from tynor is meant to be used among patients suffering from any injury or sprain in these regions. The splint is meant to provide controlled compression in various orthopaedic conditions. The splint immobilizes the area that helps in a speedier recovery. It has anatomical thumb opening that allows free movement of the thumb. It provides a lot of comfort and is easily breathable.
Forearm splint is the term used to describe the forearm pain similarly the pain of lower leg over the shin is known as shin splints. Forearm splint describes the painful disease of elbow or wrist joint. Continuous pain in forearm is often caused by tendonitis, joint injury or hairline fracture of forearm bones (proximal radius or ulna near elbow joint). Overstretching of the elbow joint often causes forearm injury. Symptoms consist of a dull pain in the forearm. Pain is minor initially but increases as activity continues. Often pin-pointed to the dorsal or back of the hand side of the forearm, mid-way between the wrist and elbow. The patient may experience weakness in the wrist extensor muscles and tenderness deep in the forearm. Pain may be reproduced by attempting to bend the wrist backwards against resistance.
They provided wrist splints are used in different medical institutions and hospitals for management of hand fractures. Our offered wrist splints are manufactured by skilled professionals using optimum quality basic material and advanced technology as per the set norms of market. As well, these wrist splints can be availed in v
editorial discussion of the benefit of vitamin D in mitochondrial function. Those in the vitamin D repletion arm of the study had a quicker recovery time to restored phospho-creatinine levels. The quicker the recovery of phospho-creatinine levels, the shorter recovery phase and the likely improvement in athletic performance.
T3 in the post MI individual decreases the MI infarct size and the progression to heart failure. What is really interesting about this study is that the T3 induced mitochondrial biogenesis and activity which is a great thing in recovery of MI and also in disease i.e. cancer. However, it appears to increase HIF-1alpha and angiogenesis which is stimulated by retrograde signaling. There is a muddied picture here. Because T3 stimulates oxidative phosphorylation and mitochondria biogenesis which is favorable for health. However, in this study of rats, it induced HIF-1alpha and angiogenesis in post MI, which is favorable to recovery, yet this is unfavorable for cancer. Yet oxidative phosphorylation is favorable to cancer prevention/elimination and MI recovery.
"Heavy resistance exercise" associated with acute increase in TT and fT in men. No changes were see in basal T and fT in recovery or AR. The recovery phase was estimated to take 6 days.
Whey protein is beneficial as supplementation for resistance training recovery. This study found the addition of a leucine metabolite, beta-hydroxy-beta-methylbutyrate, and the carbohydrate Isomaltulose before, during, and after high intensity exercise further augmented recovery.
competition versus recovery period in wrestling reveals different salivary hormone ratios. Competition results in low Testosterone to cortisol ratio versus the recovery phase which was found to be associated with a high testosterone to cortisol ratio.
salivary hormone evaluation reveals cortisol increases during athletic competition due primarily to a increase in salivary cortisol production. The result is a decrease in T:C ratio during competition. In the recovery phase, cortisol decreases to baseline, but the testosterone rises above baseline, thus increasing the T:C ratio in the recovery phase. This lasted up to 5 days in this study.
this study looked at salivary testosterone and cortisol in exercise recovery. They found a low T/C ratio in this athletes. This is a catabolic state. A normalization of the a low T/C ratio will increase muscle recovery and should improve performance. Testing was with saliva
Very interesting article. Early Progesterone treatment, in animal model, shown to improve neuropathic pain recovery. This is by no means the first study to show this. This has been shown numerous times in TBI, but the timing of therapy was the purpose of this article. What is very interesting here is that the metabolites implicated here in the recovery are the same metabolites implicated in an increased tumor potential.
The polyunsaturated fatty acids linoleic (LA, 18:2n-6) and linolenic acid (LNA, 18:3n-3) are essential fatty acids that cannot be synthesized by the body.
LNA serves as the precursor for long chain omega-3 fatty acids such as docosahexaenoic acid (DHA) while LA is converted into long chain omega-6 fatty acids such as arachidonic acid (AA)
DHA and AA are abundantly found in the brain, where these are stored mainly in membrane phospholipids
DHA has been shown to increase neurite outgrowth and synaptogenesis, and promotes glutamatergic neurotransmission through increase in glutamate receptor subunit expression
DHA has been shown to be converted to anti-inflammatory, proresolving and neuroprotective mediators, such as resolvins [7] and protectins
AA is converted by cyclooxygenases into 2-series prostaglandins and 4-series leukotrienes, most of which exert pro-inflammatory effects
Supplementation of DHA exerts neuroprotective effects and has been reported to afford protection from diffuse axonal injury [11] and mixed brain injury [12] as well
severe depletion of membrane DHA in the brain renders mice significantly more susceptible to TBI and impairs recovery following the injury
Omega-3 fatty acids may serve as nutraceutical agents and precondition the brain to make it more resilient to injury
it can be suggested that enriching DHA in the brain may be prophylactic and protective against brain injury
severe DHA deficiency in the brain impairs functional recovery from TBI in terms of vestibulo-motor and cognitive deficits
DHA deficiency further elevates TBI-induced production of SBDPs
less neurons were found around the injury site of DHA deficient brain after TBI compared to the omega-3 fatty acid adequate group
Nice study and review of other studies that looked at post-exercise recovery strategies. This authors conclusion, and I concur, is that a mixture of carb 0.8 g/kg and protein 0.2 g/kg mixture immediately and 2 hours post is the best to restore glycogen stores and promote an anabolic state
Creatine supplementation shown to improve muscle recovery in injury. The dosing included the standard loading dose at 0.3 g/kg of body weight divided in multiple doses. Maintenance was at 0.1 g/kg of body weight.
Could Ginger be aid in recovery? Results are mixed. Study finds 4 g of ginger improves strength in muscle recovery, yet no change in muscle biomarkers.
Carbohydrates required to restore muscle/liver glycogen stores. This older article, abstract available, points to 8-10 grams of carbohydrates/kg body weight. Though repletion of glycogen stores can occur, recovery of muscle performance may require longer time. Studies have point to 4-6 days.
