Little athletes are suffering big injuries due to coaches and parents piling on too much training. Any athlete can be injured by overtraining – more so with young athletes under the age of 12. More children are being pushed beyond their physical limits – sports injuries often seen at the pro level are being seen on the children’s playground. Coaches and parents need to take into consideration the age and developmental stages of physical growth.

Dr. Kazushige Goto of the University of Tokyo noted in the Journal of Applied Physiology that breaking up exercise sessions by adding rest periods may boost a workout’s fat-burning efficiency. Two 30-minute sessions and a 20-minute rest break in between were seen to burn more fat than a 60-minute session.
According to NCAA president Myles Brand, the governing body of the NCAA issued letters to schools based on academic performance. Schools receiving warning letters could face harsh sanctions in the future. A second offense could result in a reduction of practice time or games played.
A study in the New England Journal of Medicine suggests that obesity is socially contagious. Research explains that a person’s perception of body size is affected by friends.
In the past 25 years, obesity among U.S. adults has shot up from 15 to 32 percent.
Most studies have now largely exonerated dietary fat – total, saturated, or otherwise – from playing a significant role in causing cancer. However, evidence suggests that limiting fat intake to less than 15% of your daily calories may prevent breast cancer and prostate cancers from progressing or recurring.
Recent studies have shown that sleep deprivation cuts into the academic and athletic performance of college students. Short-term side effects of sleep deprivation include delayed reactions and the tendency to make mistakes. A sleep deficit over just five nights can significantly stress the heart.
Researchers from the U.S Centers for Disease Control and Prevention (CDC) found that college football players get injured more than high school football players, but high school injuries seem to be more severe. Boys between the ages of 10-14 were most likely to end up in the emergency rooms with traumatic brain injuries due to activities such as bicycling, horseback riding, football, basketball, and the use of all-terrain vehicles (ATVs).
For some time, misinformation about nutrition has confused us all. Let’s see what science says about these myths:
A healthy diet that includes a variety of so-called “super-foods” can help maintain your weight, fight disease, and live longer. These foods include:
Consuming a variety of antioxidants is the key to preventing disease. Research shows a diet rich in fruits, vegetables, grains, and legumes keeps cells healthy, repairs DNA damage from toxins, slows the growth of cancer cells, and fights oxidation, a chemical process that damages cells.

The Yankee Years gives an in depth review of Joe Torre’s stint as the manager of the New York Yankees. The highly successful run of Torre’s early years with the organization (Four World Championships from 1996-2000) contrasts his later years and the events that led to his downfall. Students involved in sport management have an opportunity to examine the relationships between administrative positions-Manager, General Manager, and Owner-of the most famous professional sport organization in the world.
Athletes are facing an attack from a new competitor. This competitor can be deadly. This competitor is called MRSA – Methicillin-resistant Staphylococcus Aureus Bacteria – commonly known as “Staph Infection”.
Today it seems that athletes have a new opponent to contend with and it is not another athlete from an opposing team. This nasty bacteria does not respond to commonly prescribed antibiotics and attacks the body fast. According to infectious-disease experts from the CDC – this germ is as tough and resilient as the athletes it attacks.
Today, one can see that physical training for sport-performance has become very scientific. Coaches and athletes must have a thorough understanding of human movement, the biomechanics and the physiology involved and how these scientific concepts and factors apply specifically to sport-performance.
By studying the dimensions of the mechanics and the proper execution of a movement, one can come to realize the importance of the physical factors that are at play. These physical factors are all based on physical laws and principles of physics. Knowledge and understanding of these physical factors provide a scientific foundation for the training programs for sport-performance.
Introduction
Physical activity and sport by their very nature include inherent risks leading to injuries for many individuals who participate (1). Most sports injuries encountered by young athletes are minor in nature, but when an injury is extensive enough to be categorized as catastrophic it can be devastating to those involved.
Fortunately, catastrophic injuries are rare, but it remains important to be aware of the remote possibility of their occurrence and the need for shared the responsibility for the management of such injuries. All who are involved should assume a strong sense of accountability for the healthcare and safety of young athletes participating in physical activity and sports.
With the sport supplement industry last year alone topping out at over $6.1bn, up 7.5 percent from 2006, it is hard to imagine what percentage of this total amount was purchased by athletes 18 years of age and younger. A large part of the athletic culture in high school is now consumed by the image of the shredded athlete who will grace the cover of a major publication, or one of the many commercials showing an athlete who is bigger, faster and stronger.
It is not surprising that due to this popular media image of what an athlete should look like, many of today’s youth athletes are turning to illegal drugs at an alarming rate to achieve what they may consider a measure of success. Research by Calfee and Fadale (2005) showed that up to one third of high school students who use anabolic steroids are in the population of non-athletes who use steroids to improve appearance (as cited in Buckley et al., 1988, p. 3441). Current estimates put the number of US athletes taking some form of illegal drug or steroids specifically at 1 to 3 million (Silver, 2001). One can only imagine how this number breaks down to the high school and middle school level.
Introduction
There is both anecdotal and epidemiological evidence that regular moderate exercise reduces the risk of infections by having a positive effect on the immune system( Pacque, Booth, Ball, & Dwyer, 2007). Couple physiological factors and changes associated wit peak performance and relationship with elite athletic performance. Several studies have examined various physiological responses associated with the cardiorespiratory, metabolic, hormonal, neuromuscular and immunological systems during the pre-event taper across a number of sports (Mujika, Padilla, Pyne, & Busso, 2004).
The May 2008 Court of Arbitration for Sport (CAS) ruling opened the way for South African sprinter Oscar Pistorius to attempt to qualify for the 2008 Olympic Games. The implication of the CAS ruling could alter the world of track and field as it currently exists. Pistorius, a double amputee, had been banned from competing in International Association of Athletics Federations (IAAF) sanctioned events against able-bodied athletes in January 2008. At issue for the IAAF, track and fields world governing body is whether Pistorius’ use of technology provided him with an unfair advantage over able-bodied runners (CAS, 2008).
The technology in question, carbon-fiber cheetah flex-foot prosthetics, according to the IAAF, violated a competition rule prohibiting the use of technical devices that incorporate springs, wheels or any other element that provides the user with an advantage (IAAF, 2008). The IAAF’s decision was based on an Italian laboratory’s examination of a videotape of a Pistorius race held in Rome and a two-day biomechanical examination conducted in Cologne, Germany (CAS, 2008).
Introduction
In 2008, Taekwondo became recognized as an official sport at the Begin Olympics. Taekwondo is a full contact free-sparring sport which awards points for head contact. Weight cycling is a term used to describe rapid weight loss following self-induced food limitation and/or dehydration. Both gradual (seasonal) and rapid (weekly) weight reduction cycles are used by athletes, and have been investigated for potential effects on nutrition and performance (Mohsen Heather,& Young ,2005). These cycles are used in various sports such as judo, rowing, wrestling, and boxing in order to make a weight category. Like many of these sports, Taekwondo consists of repeated-effort, high intensity physical demands. Although the World Taekwondo Federation has eight distinct weight classes per gender for all competitions and championships except for the Olympic Games, no rulings have been implemented to address weight cycling in the sport (Mohsen, Heather, & Young , 2005).Overtraining syndrome is a neuroendocrine disorder characterized by poor performance in competition, inability to maintain training loads, persistent fatigue, reduced catecholamine excretion, frequent illness, disturbed sleep and alterations in mood state(MacKinnon, 2000).
