Introduction: Proper nutrition is important for the health and performance of athletes. However, a lack of knowledge might lead to negative attitude and poor dietary practices. This study aimed to determine the levels of nutrition knowledge, attitude, and practice (KAP) among male gymnasium users in Jordan. Methods:A total of 138 male gymnasium users (21.1±2.8 years) from Jordan were recruited. Their height, weight, body mass index, and age were recorded. The KAP-Sports nutrition questionnaire that contains 25 questions regarding knowledge on basic sports nutrition, 12 questions regarding usual food choices and practices, and 20 questions on attitude towards nutrition and sports-enhancing diet were administrated. Descriptive and Pearson correlation analyses were used to analyse the data. Results: Majority of the participants had moderate knowledge on sports nutrition (77.6%), neutral attitude (84.7%), and fair dietary practice (67.4%). Mean score for knowledge, attitude and practice were 18.1±2.6, 58.8±6.2, and 29.7±3.6, respectively. There was significant, weak correlation between knowledge and attitude (r=0.18, p=0.048), as well as between knowledge and practice (r=0.20, p=0.018). Conclusion: Knowledge is important to affect positive attitude and good dietary practices. However, gymnasium users in Jordan did not have a high level of knowledge that could lead to their positive attitude and good dietary practices. Thus, sports nutrition education is recommended to ensure that adequate and correct knowledge are disseminated to gymnasium users.

Participation in exercise benefits health and fitness among Intellectual Disability (ID) individuals. Circuit training is one of the exercise programme that can be tailored by manipulating the intensity, time and types of exercise. The purpose of the present study is to examine the effects of six weeks of circuit training on anaerobic fitness and simple reaction time in ID individuals. Thirty participants with mild to moderate ID were selected from individuals who are registered with the Pusat Pemulihan dalam Komuniti (PDK) and Yayasan Orang Kurang Upaya (YOKUK) in the Kelantan state. Participants were randomly divided into Circuit Training and Control groups. Participants in Circuit Training group followed a circuit training exercise programme, two times per week for six weeks, whereas participants in Control group were not involved in circuit training and carried out their regular activities. The anaerobic peak power was significantly decreased (ƿ < 0.001) in Control group after six weeks. The anaerobic power of post-test was significantly improved (ƿ = 0.042) from the pre-test in Circuit Training group and it was also significantly higher (ƿ = 0.001) than Control group. There were no significant differences for the anaerobic capacity and simple reaction time between and within groups. Circuit training can be conducted to enhance anaerobic power in ID individuals, however longer participation may be needed to improve anaerobic capacity and simple reaction time.

Aim and design: L-carnitine supplementation combined with exercise may enhance metabolic responses and improve exercise performance. Thus, this systematic review article aims to identify the effects of the L-carnitine supplement on biochemical markers, and exercise performance when combined with exercise. Data Sources: The articles are screened and reviewed based on titles, abstracts and keywords. Only peer-reviewed studies written in the English language, dated January 2000 to March 2021, were considered in this review. Review Methods: The PRISMA method is used for this study. PubMed, EBSCOHost, SpringerLINK, and Scopus databases were used to systematically search. Results: From a search 731 articles, 12 articles were identified related to effect of L-carnitine intake with exercises on biochemical markers and exercise performance. Studies showed that L-carnitine supplementation can be consumed daily during aerobic or anaerobic exercises by different population including patients. Its combination could improve serum lipid profiles, antioxidant properties, markers of metabolic, oxidative stress, and inflammatory, and exercise performance. Conclusion and Impact: This review provides information regarding the beneficial effects of L-carnitine supplement with recommended dosages and exercise prescriptions on overall body health in human.
