- THE CAUSES OF DELAYED MENARCHE IN FEMALE ATHLETES -

INTRODUCTION
Greater emphases on the benefits of exercise have led to a greater participation of women
in sport at all levels. Exercise has been promoted, endorsed and encouraged in the medical
community as a way to reduce stress and maintain a healthy lifestyle. While moderate
exercise does provide valuable benefits, intensive exercise associated with elite female
athletes poses serious health risks to the female body.

The female reproductive system is very intricate and highly sensitive to physiological
stress. This increased stress level is often associated with several reproductive
abnormalities such as delayed menarche, primary and secondary amenorrhea and
oligomenorrhea occurring in 6-79% of women engaged in athletic activity (Warren and
Perlroth 2001). This wide range of percentages is a result of various levels of athletic
discipline and level of competition (Abraham et al. 1982, Glass et al. 1987).

The aforementioned reproductive abnormalities are largely the result of hypothalamic
dysfunction and disturbance of the gonadotropin-releasing hormone (GnRH) pulse generator.
This suppression of GnRH results in possible infertility and an irreversible decrease in
bone density. The scientific community seems to be split however, on the specific trigger

  • Endorphines
    Endorphines Endorphins In 1975, Dr. John Hughes and Dr. Kosterlitz discovered Endorphins. It has been confirmed that Endorphins have both neurological and spinal effects. Twenty different types of Endorphins have been discovered in the nervous system. The most effective, beta-endorphin, which gives the most euphoric effect to the brain, has been found to be composed of 31 amino acids. The word Endorphin is abbreviated from \'endogenous morphine\' which means morphine produced naturally in the bo
  • Bone
    Bone BONE The skeletal system includes the osseous tissues of the body and the connective tissues that stabilize or interconnect the individual bones. The bone is a dynamic tissue. Throughout the lifespan, bone adjusts to the physiologic and mechanical demands placed on it by the processes of growth and remodeling. Bone serves the organism at multiple levels: As a system, bones permit the organism to locomote effectively and to maintain posture by bearing loads without deformation, by providing

  • Plant hormones
    Plant hormones Plant hormones are specialized chemical substances produced by plants. They are the main internal factors controlling growth and development. Hormones are produced in one part of a plant and transported to others, where they are effective in very small amounts. Depending on the target tissue, a given hormone may have different effects. Plant hormones play an integral role in controlling the growth and development of plants. A plant hormone is generally described as an organic comp

All organelles within the cell are well rehearsed in their operations, but an error on an organelles behalf, can send the cell and it\'s organelles into panic. The efficiency rate of the cell plummets down to a low level. It does take so

    performance enhancing drugs I\'m pretty sure you all have engaged in some sort of athletic competition that could be classified as a sport. If you can say that you have, most of you could not keep up with some of the more naturally athletically gifted people you were competing with or against.. If you are sitting there remembering that feeling of being inadequate, thinking back when your parents told you all that mattered is that you tried your best, was a huge crock. No matter how hard you trie
  • Proteins
    Proteins Proteins Discovered in 1838, proteins are an organic compound that makes up living organisms and are essential for life. Proteins are the macromolecules of life. Proteins have many different properties and function in a variety of ways. They function as a building structure, in teeth, bones and muscles. They also serve as enzymes, hormones, and neurotransmitters. Its functions of a protein are the most diverse of any family. Whether found in humans, animals, or plants proteins are made

An element in a pure substance that can be broken down in to smaller units called protons neutrons and electrons. There are over 100 elements on our planet. Did you know that DNA is a nucleotide because of it basic structural units which contains sugars joined together to form what looks like a winding ladder? Elements can be bonded either by covalent bond, i
  • The Mind-Body Connection
    The Mind-Body Connection The mind has an incredible power. We see it as we go through our everyday activities, constantly displaying the wonders of logic, thought, memory and creativity. Yet, can the mind be more powerful than we know? Is it possible to reduce or even eliminate pain, illness and disease by using the natural powers it possesses? Can the mind heal? Many of our finest researchers and scientists have explored that question, and while the exact answer still eludes us, the facts seem
