Children and muscle building programs‚ a safe choice? The importance of exercise in childhood development is beyond any discussion and we all realize that kids are more and more engaging in a sedentary lifestyle much like adults. So‚ it is very important to educate your child in healthy habits and to help develop a workout routine that is suitable for him or her. The question that is posed in this article is: should a bodybuilding workout be included in that routine? To start‚ let us define

When it comes to muscle contraction‚ contraction takes place in the muscle fibers. Muscle fibers are the basic building blocks of the muscle and what allow muscles to contract. They appear as long cylinder cells that contain several nuclei. Contraction happens when the muscle receive signals from the nervous system and the Neuromuscular Junction obtains the muscular exchange where the synaptic bulb and the muscle fibers connect. muscle fibers are composed of myofibrils‚ which contain contractile

performance of the athlete both in physical and mental terms. The athlete needs to learn to notice the signs of fatigue and tension that arises from this and introduce methods to cope with the debilitating effect it can have on their performance. Muscle fatigue and the tension associated with it can result from a number of different factors. The athletes may simply have over exerted themself physically in training or competition leading to muscular fatigue from pushing their physical limits. They

The series of events prompting muscle contraction is started some place in the central nervous system‚ either as willful action from the brain or as reflex action from the spinal cord. Beginning with depolarization at the neuromuscular junction‚ the depolarizing impulse discharges acetylcholine from the nerve ending. Which then diffuses over the neuromuscular junction (a chemical synapse formed by the contact between a motor neuron and a muscle fiber). At the motor end plate‚ the acetylcholine joins

Skeletal dysplasias are a group of disorders characterized by abnormalities in the growth and remodeling of cartilage and bone. These dysplasias affect the skull‚ spine‚ and extremities. Achondroplasia is the most common type of skeletal dysplasia. It is a genetic condition that results in abnormally short stature with disproportionately short limbs. It occurs in about 1 in every 15‚000 to one in 40‚000 births. In approximate 80% of the cases‚ it is caused by a spontaneous mutation to the FGFR3 gene

"The Politics of Muscle" by Gloria Steinem is an essay arguing the difference in strength between men and women. Steinem starts her essay by stating how she grew up in a generation where women didn’t participate in a lot‚ if any‚ sport activities. She goes on to say that she believes this is the reason why women of her generation believe that it’s not what the female body does‚ but how it looks. Steinem feels that women always seemed to be owned in some degree as the means of reproduction. She believes
