BACKGROUND: Creatine (CR) is considered an effective nutritional supplement having ergogenic effects, which appears more pronounced in upper-body compared to lower-body exercise. Nevertheless, results regarding the impact of CR loading on repeated high-intensity arm-cranking exercise are scarce and in some cases conflicting. Interestingly, few of the conducted studies have structured their research designs to mimic real world sporting events. Therefore, our purpose was to address the hypothesis that CR ingestion would increase anaerobic power output in consecutive upper-body intermittent sprint performance (UBISP) tests designed to simulate wrestling matches on a competition-day...

Judo competitions are divided into weight classes. However, most athletes reduce their body weight in a few days before competition in order to obtain a competitive advantage over lighter opponents. To achieve fast weight reduction, athletes use a number of aggressive nutritional strategies so many of them place themselves at a high health-injury risk. In collegiate wrestling, a similar problem has been observed and three wrestlers died in 1997 due to rapid weight loss regimes. After these deaths, the National Collegiate Athletic Association had implemented a successful weight management program which was proven to improve weight management behavior...

Magnesium is involved in numerous processes that affect muscle function including oxygen uptake, energy production and electrolyte balance. Thus, the relationship between magnesium status and exercise has received significant research attention. This research has shown that exercise induces a redistribution of magnesium in the body to accommodate metabolic needs. There is evidence that marginal magnesium deficiency impairs exercise performance and amplifies the negative consequences of strenuous exercise (e...

Growth at puberty depends on one's genetic potential, nutritional status and a series of hormones. Energy expenditure may modify the effects of these three factors on the linear growth rate and the relative proportions of fat-free and fat mass. Participation in sports where weight control is not required does not seem to affect pubertal timing or alter linear growth rate. The growth and maturation of athletes in weight control sports have the additional burden of energy output greater than intake; however, in only a minority the energy deficit is great enough to slow growth and maturation...

Adolescent wrestlers (n = 9, 15.4 yr) and recreationally active control adolescent males (n = 7, 15.7 yr) were measured before, at the end (late season), and 3.5-4 mo after a wrestling season to assess the influence of dietary restriction on growth, maturation, body composition, protein nutrition, and muscular strength. Controls consumed adequate amounts of energy, carbohydrate (CHO), protein, and fat, and demonstrated normal gains in weight, fat mass (FM) and fat-free mass (FFM). Wrestlers consumed a high-CHO (61 +/- 2% kcal), low-fat (24 +/- 2% kcal) diet during the season but did not consume adequate energy (24...

Despite a growing body of evidence admonishing the behavior, weight cutting (rapid weight reduction) remains prevalent among wrestlers. Weight cutting has significant adverse consequences that may affect competitive performance, physical health, and normal growth and development. To enhance the education experience and reduce the health risks for the participants, the ACSM recommends measures to educate coaches and wrestlers toward sound nutrition and weight control behaviors, to curtail "weight cutting," and to enact rules that limit weight loss...

The ascorbic acid (AA)-status of 14 marathon runners, 12 soccer players, 9 wrestlers, 9 basketball players and 16 controls was determined. A 7-day food weighed record was kept to quantify the AA-intake. In addition, the AA-serum concentrations and urinary ascorbate excretion were measured. The AA-intake of all 44 athletes (median, 26th-75th percentile) was 180.7 (188-239) mg/d, the serum concentration 70.6 (65.7-80.2 mumol/l) and the urine ascorbate excretion 1531 (391-2934) mumol/g creatine. No significant differences could be observed between the various sport groups, or between the sport groups and controls with respect to absolute (mg/d) and relative (mg/g body weight) AA-intake, serum and urine concentrations...

Weight loss is a part of any competitive sport which matches participants of equal weight or sports where participating at lower weights or with a thinner body habitus is considered an advantage. For some wrestlers, weight loss is excessive and often accomplished by methods that lead to loss of lean body mass and total body water. There is convincing evidence that this excessive weight loss is unhealthy for all individuals who follow these practices. Even greater harm is experienced by high school wrestlers who have not yet completed their growth and development...

In 1989, the Wisconsin Interscholastic Athletic Association implemented a project including new rules and an educational program, consistent with ACSM and AMA guidelines, to curtail "weight cutting" among high-school wrestlers. The project included skinfold estimates of body fatness to determine a minimum competitive weight, a limit on weekly weight loss, and presentation of nutrition education information to help wrestlers diet effectively. Implementation of the project has overcome a variety of obstacles and has received widespread endorsement from parents, teachers, wrestlers, and coaches...
