“…The most frequent methods used by judo players were increased exercise, restricted food ingestion, training in heated rooms, gradual dieting, and fluid restriction [7]. In accordance with several reports our results showed that rapid Weight loss affects negatively performance in judo athletes [41]. We herein argue that rapid Weight loss clearly meets all three criteria and, therefore, should be banned from the sport [42], Considering that these health-threating methods are more commonly used by lower level athletes, specific education programs should be directed to them [43].…”

Purpose: The purpose of this study was to determine the ultimate body mass, performance, and nutritional characteristics of the Algerian judo junior athletes, and also analysing the impact of nutritional intakes on stabilising Weight loss according to special performance of judo athletes. Material: Twenty-one male university athletes (aged: 21.45 ± 1.32; height: 1.81 ± 0.45 m; and body mass: 73.9 ± 4.1 kg) participated in this study during a period of stabilising Weight loss before and after 15 days of caloric restriction. Athletes were submitted to anthropometrical measurements and performed the Special Judo Fitness Test. Values for nutrient intakes were obtained from a 15 day food record kept during a training camp period of Weight maintenance and after a 15-day caloric restriction. Results : caloric restriction resulted in significant decreases in body mass (73.73 ± 2.1) and performance. However, Special Judo Fitness Test index increased significantly (14.00 ± 1.75) during caloric restriction in comparison to stabilising Weight loss. Conclusion: Exercise and caloric restriction lead to determine the ultimate Weight and physical performance. The present study provides baseline nutritional data that can be used in the prescription of individual training programs for university judo Athletes.

“…Education and advocacy efforts have been used to attempt to change this perception, and although the effects have been largely positive, unsafe cultural norms reflecting incorrect information persist in some settings. 33 When the socioecological framework was redefined by McLeroy et al 9 in 1988, the environmental level also included the physical environment, such as access to parks and transportation. In sports medicine, the environmental level may also refer to the actual environmental and playing-field conditions, and interventions can be designed to directly address these factors (eg, cancel activity during extreme weather, ensure playing conditions are safe).…”

The socioecological framework is a multilevel conceptualization of health that includes intrapersonal, interpersonal, organizational, environmental, and public policy factors. The socioecological framework emphasizes multiple levels of influence and supports the idea that behaviors both affect and are affected by various contexts. At present, the sports medicine community's understanding and application of the socioecological framework are limited. In this article, we use the socioecological framework to describe potential avenues for interventions to reduce sport-related deaths among adolescent participants.

“…Rapid weight loss is an act of losing weight in a short time to reach the standard necessary to compete in a specific weight class. It is characterised as transitory weight loss of no less than 5% of one's weight within a short period of time (a week) [8]. In some situations, RWL can be practised as late as the day before the competition.…”

Introduction. Rapid Weight Loss (RWL) is a common practice in combat sports where weight is classified to ensure equitable competition in terms of strength and agility. This study aimed to investigate the profiles of non-elite combat athletes and their RWL practices.Material and methods. This research was a cross-sectional study conducted in Kuching, Sarawak. Data were collected using a validated self-administered dual-language questionnaire.Results. A total of 65 respondents participated in the study; two-thirds were male, and the majority were taekwondo athletes. About 66% of the respondents reported to have practised rapid weight loss, with average weight loss of 3.4 kg (SD = 1.90) and highest weight loss of 4.9 kg (SD = 3.16). The most common RWL methods used were exercising more (69.8%), gradual dieting (51.1%), and training in heated rooms (20.8%). Physical trainers and training colleagues were rated as persons having the most influence on the use of RWL by the respondents. The perceived adverse effects which were mentioned the most frequently by the respondents were fatigue (69.2%), decreased vigour (50.8%), and muscle cramps (46.2%). As for the type of combat sport practised, muay thai and jiu jitsu had the highest number of respondents who used RWL. There were significant differences in RWL practices depending on the influences of training colleagues, physicians/doctors, physical trainers, parents, dieticians, and former athletes as well as perceived adverse effects of RWL.Conclusions. The findings of the current study were observed to be similar to those of research involving elite combat sport athletes where the prevalence of RWL was reasonably high, with similar characteristics. A proper regulatory programme should be put in place to assist both the athletes and their coaches/trainers in implementing proper weight control.
