Low carb diets and strength training

Just saw this abstract - lower calories whether low carb or not - can help to lose body-weight but won't affect strength? So you don't need carbs to display strength. Effects of short-term very low-carbohydrate or conventional diet on strength performance AIM : Weight reduction strategies usually include diet and regular physical activity. A very low-carbohydrate and high protein diet (VLCD) may be preferred instead of a low energy conventional diet (CONV). The effects of VLCD on strength performance are yet to be understood. Aim of the study is to determine the effects of two different restrictive diets on strength performance. METHODS : Sedentary women were assigned to either a VLCD (less than 40 g carbohydrate; n=12) or a CONV diet (500 to 800 kcal restrictive; 48%, 22% and 30% from carbohydrate, protein and fat, respectively; n=12). Knee extension isokinetic strength tests (3 yen 15 reps at 60 degrees .s-1, with 90 or 180 s rest interval between sets) were performe...

Fancy shoes - don't bother

If you have ever bought running shoes from a specialist shop the assistants will likely have examined your foot and your gait and prescribed a particular style of shoe - motion control, cushioned or whatever.... Maybe it is all a waste of time and money! Chalk up another one for barefoot running . Injury Reduction Effectiveness of Assigning Running Shoes Based on Plantar Shape in Marine Corps Basic Training Abstract BACKGROUND : Shoe manufacturers market motion control, stability, and cushioned shoes for plantar shapes defined as low, normal, and high, respectively. This assignment procedure is presumed to reduce injuries by compensating for differences in running mechanics. HYPOTHESIS : Assigning running shoes based on plantar shape will not reduce injury risk in Marine Corps basic training. STUDY DESIGN : Randomized controlled clinical trial; Level of evidence, 1. METHODS : After foot examinations, Marine Corps recruits in an experimental group (E: 408 men, 314 women) were provided ...

mc on the shoulder

mc ( remember mc ? there is a interview with her that I did here ) has put up a very detailed piece on the mechanics of the shoulder: Part 1 : the amazing engineering that is the shoulder, part 1: scapula and shoulder girdle Part 2 : the amazing shoulder - part 2: glenohumeral joint & muscles (yes rotator cuff too) There is some fascinating reading there. In part one of this quick tour of the amazing shoulder we looked particularly at the shoulder girdle and the muscles that act pretty much directly on the scapula. The main take away was that significant muscles like the traps, rhomboids, pec minor, serratus anterior and levator scapula all work pretty much *just* to move the scapula and so reposition the shoulder joint socket to extend range of motion for the arm moving in the shoulder. In this piece, we'll overview those pixie rotator cuff muscles and look at why they can be such a pain - in the shoulder - and how understanding the movements these muscles support may help r...
