Abstract

PURPOSE
The aim of this study was to assess the effects of a resistance exercise session (RES) on free amino acid concentrations and protein synthesis and breakdown of the vastus lateralis (VL) muscle during recovery in male subjects.

METHODS
Both the exercise group (EG) and the control group (CG) consisted of six healthy physically active men. On the experiment day in fasting conditions, a stable isotopic tracer of L-[ring-2H(5)] phenylalanine was infused and EG started a heavy 50-min hypertrophic RES for lower extremities after 55 min of infusion. At the same time, CG was at rest. During recovery of 195 min after RES, several blood samples were drawn from the femoral artery (FA) and the femoral vein (FV) and muscle samples from the VL muscle. The enrichment was analyzed by GC/MS and leg muscle amino acid kinetics determined by three-pool compartment model between FA, FV, and VL.

RESULTS
During recovery at 60 min after RES, there was no difference in muscle protein synthesis or muscle protein breakdown between the groups, but at 195 min, both muscle protein synthesis (P < 0.05) and muscle protein breakdown (P < 0.05) were increased in EG compared with CG. The protein net balance was negative and similar in both groups. Simultaneously in serum concentrations, there was a decrease in leucine (P < 0.05) associated with an increase in aspartate (P < 0.05). Furthermore, the exercise-induced increase in alanine concentration decreased both in serum and muscle.

CONCLUSION
In fasting conditions, protein net balance is negative and RES induces an increase in muscle protein synthesis and breakdown at 195 min but not yet at 60 min of recovery.

The Future of Oil - Video

The Future of Oil (2006)

A nother take on the oil situation, with less talk of doom and the end of civilization. Prof Roland Horne, of Stanford University, explains how much oil we have left. Gives the history of oil production, Peak Oil, and current oil exploration.

There's approximately Two Trillion barrels of oil left on earth, but we'll only be able to extract half. We've used around One Trillion barrels to date, with demand growing as China and India develop, and catch up with the west.

A Crude Awakening - The Oilcrash

Peak Oil Documentary (2006)

I f you haven't heard of peak oil, here's a primer for what's in store when the world runs out of oil. Its hard to comprehend how oil is so ubiquitous. It's everywhere and in everything, from our food, our cars to our clothes, footwear, medicine, phones and more. It's in everything.

Essential viewing.

Runtime: 94 mins.

Give it a shot.

Addicted To Milk And Wheat

The Addictive Opioids In Wheat And Dairy Foods

Dairy and wheat products contain opioid peptides influencing endorphin receptors in the brain. These peptides are physically addictive, causing asthma, obesity, apathy, dependence, ignorance and numbness. The same goes for beta-carbolines in prepared food.

To be sharp and investigative, you ought to consume neither dairy- nor wheat-products. You don’t need those ‘foods’ at all.

To obtain all required nutrients and to remain sharp and investigative; consume as much fruits (there are about 6000 different fruits), and some fresh raw animal food regularly (like sashimi or egg yolk). And for munch-food; only consume what you really, really love to eat (and not because they say it’s healthy), containing little protein, but much fat and / or sugar, satisfying your cravings for munch-food.

Wheat- and dairy-products are not foods but drugs.
