Leg curls exercise

Lying leg curls bodybuilding exercise technique: 



Lie facedown on the leg curl machine and place your feet under the roller pads, with your knees just over the edge of the bench. Slowly curl your lower legs up until they’re almost touching your buttocks. Once in this fully contracted position, hold the contraction for a two-count, and then lower the resistance slowly back to the starting position. Repeat for your I.S.R., and then reduce the weight by 20 percent and perform a second I.S.R. set.

At this point in the routine, your legs are bound to feel rather wobbly—and with good
reason! Nevertheless, you still have the rest of your physique to deal with, and we’ll train
it with only one I.S.R. set per bodypart with the following exercises.


Muscles Involved during the exercise:

Primary: Hamstrings.
Secondary: Gluteals, calf muscles.

Supplementation in bodybuilding

Supplementation in bodybuilding  became an essential part. Aggressive marketing has led millions of athletes to use dietary supplements. To cite only one example, a 1993 survey of the marketplace found 624 commercial products targeted to body builders, making more than 800 unsubstantiated health and performance claims. Many athletes take common vitamin and mineral supplements and may also take a wide variety of other less common supplements In spite of abundant evidence that bodybuilders’ nutrient needs can be met by well-balanced diets and that most supplements have no measurable effect on performance in well-nourished athletes, some athletes still take substantial quantities of supplements.

Supplement abuse can cause short-term acute symptoms such as nausea or diarrhea and long-term adverse effects such as nutrient imbalances or toxicity. Furthermore, some supplements contain substances banned by athletic governing bodies and some may contain impurities. Many clients do not think to report various supplements in a diet record or recall interview because supplements may not be considered food and they are often not consumed with meals. Bodybuilders may also be reluctant to disclose the use of some supplements, especially those that are prohibited by sports governing bodies. Information on the use of supplements must be  elicited by educated probing. The professional should be familiar with the range of supplements used by athletes in various sports and should develop a rapport with clients that will facilitate probing about the use of supplements, both the common vitamin and mineral preparations and the more exotic products targeted to athletes. identifies common supplement categories that athletes might use.

Protein Requirements for bodybuilding (resistance trained) athletes (IId part)

Protein Requirements for bodybuilding (resistance trained) athletes the first part.

 

It is apparent that, a meaningful recommendation for strength training athletes for a recommended dietary protein intake, based on the literature, is confounded by numerous factors including training status and combination of strength training with other modalities (sprint or aerobic exercise) and methodological considerations. What is certain, however, is that, even those athletes who have as their goal the gain of an impressive amount of lean mass, they do not require an enormous increase in protein intake.

Consequently, as with my recommendation for the dietary protein intake for endurance athletes, I believe that even the most ardent strength-training athletes need not consume any more than 15% of their dietary calories in the form of protein. These same athletes should, however, be getting at least 10% of their dietary energy from protein, so long as they are consuming sufficient protein to cover their energy needs or surfeit energy required for optimal weight gain. It should be emphasized that, for even for larger athletes (100 kg and greater); a sufficient energy intake to cover caloric requirements for weight gain during intense training may be in excess of 18MJ/d–1 (~4300 kcal). Hence, protein intakes as high as 20% of such an energy intake would mean a daily protein intake of 215g/d–1, which would definitely be excessive by any standard (2.15 g protein•kg–1•d–1). Hence, protein needs of this group of athletes generally should be balanced against what is onsidered necessary.
