Study Aim: The purpose of this study was to determine the correlation between hydration status, knowledge of hydration and the amount of fluid intake consumption during training among the soccer players. Material and Methods: Pre-training hydration status was measured by urine colour chart and Urine Specific Gravity (USG). A questionnaire on hydration knowledge was answered by the participants on the last day of training session. Pearson Correlation test was used to analyse the correlation between hydration status, knowledge of hydration and total amount of fluid intake among the participants. Results: The results showed that the participants were dehydrated during the three days of training. Sixty four percent of the participants had a satisfactory knowledge of hydration. However, the results indicated that the sweat loss was higher than fluid intake during the training. Pearson test revealed there were positive correlation between USG and urine colour (r=0.809, p<0.001) as well as urine colour and fluid intake (r = .424, p<0.05). Conclusions: In conclusion, the findings indicate the needs to increase awareness of pre training hydration status among the participants.

Introduction: Previous literature suggests that good nutrition knowledge does not necessarily translate into desired eating behaviours among adolescent athletes, which may affect their sports performance. The purposes of the study were twofold, which were to examine nutrition knowledge and practice between the sexes, and to evaluate the magnitude of relationship between nutrition knowledge and practice among adolescent handball athletes in Malaysia. Methods: Three hundred and twelve male and female adolescent handball players competing in a national level competition voluntarily participated in this study. The participants were asked to complete a questionnaire which consisted of items on their demographic information and about their nutrition knowledge and eating practices. Independent t-test and Pearson’s correlation were used to compare nutrition knowledge and practice between the sexes and to describe the relationship between variables, respectively. Results: The results showed that there were no significant differences (p>0.05) observed for nutrition knowledge and practice between the sexes. Besides, the results demonstrated that nutrition knowledge had a significant but weak positive correlation with eating habit (r=0.114, p=0.003) among the athletes. Conclusion: This study showed that nutrition knowledge and practice were moderately adequate, and that knowledge does not necessarily translate into good dietary practices. Therefore, the athletes would benefit from a comprehensive and innovative nutrition education, a strategy which warrants further investigation.

Purpose: The purpose of this study was to investigate the physiological responses and performance following subsequent repeated high intensity exercise with consumption of Zea may juice ( ZM ) Materials: Total of seventeen participants involved in the study. They were physically active who had cardio and strength training at least 3 times per week. The age of participants was 21.8±1.7 years old, body weight 65.4±11.2 kg and height 169.7±7.2 cm. Crossfit ‘CINDY’ exercise were repeated between two hours of rest. Treatment beverage of ( ZM ) juice vs Carbohydrate-electrolyte (CE) drinks were consumed immediately after exercise in double blind cross over manner. Number of complete set of exercise, heart rate, blood lactate and rate of perceived exhaustion (RPE) were recorded at the end of each exercise session. Results: Total number of complete ‘CINDY’ exercise significantly increased in ZM juice group during second bout of exercise compared to CE drink group. There were no significant difference in heart rate, blood lactate and RPE in both groups Conclusions: ZM juice has potentials an alternative recovery beverage to promote subsequent repeated exercise within short rest time.

The aim of this study was to investigate the effects of instructional and motivational self-talk combine with imagery and video-modelling interventions on anaerobic performance, heart rate response and self-efficacy. Forty-five active male participants were recruited in this study as they passed the screening test of Sport Imagery Ability Measure (SIAM) and scored between moderate and high. All the participants were randomly assigned into 3 groups, namely instructional group (n=15), motivational group (n=15) and control group (n=15). Participants in the instructional and motivational groups performed 12 sessions of intervention within 4 weeks. Participant in control group did not receive any specific treatment or intervention. All participants performed 30 seconds anaerobic Wingate test during the pre-test and post-test. During this test the participants" peak power, total work, fatigue index, maximum heart rate, average heart rate and self-efficacy were measured. Participants in the instructional and motivational groups answered a social validation questions within one week after the posttest. The data obtained was analyzed using a mixed-design ANOVA. The results indicated that there was a significant difference (p<0.05) only for instructional group showed specifically increased their peak power score as well as the total work in two time period (pre-test and post-test). For the self-efficacy measure, the instructional and motivational group showed the main effects and increased in the self-efficacy score during two time period. However, no significant differences were found for the fatigue index, maximum heart rate and average heart rate. Therefore, the instructional and motivational self-talk combined with imagery and video-modelling were found to be beneficial to increase individual specific task and improve their level of self-efficacy during the 30 seconds Wingate test. Overall, the instructional and motivational self-talk combine with imagery and video-modelling interventions is a useful method to improve anaerobic capacity and self-efficacy.

Carbohydrate-protein (CP) drinks have been shown to exert better effect in promoting faster muscle recovery and rehydration in exercising individuals. However, not all active people, particularly Asians can consume milk-based CP drinks that would trigger symptoms of lactose intolerance and discomfort. Thus, this study aimed to assess the feasibility of sweet corn (Zea mays) beverage as an alternative recovery drink for active people due to its high content of carbohydrate and protein as well as lactose-free. The first phase of the study was the formulation of sweet corn juice that match the specific criteria for an effective recovery drink. Next, the study on the acceptance assessment of the new formulated sweet corn juice was conducted. The results show that the product contains high carbohydrate and protein contents which met the criteria for recovery beverage for active people. Besides, the results of sensory and hedonic evaluation demonstrate that the product was well-liked and accepted by majority of the consumers. To conclude, sweet corn juice which is lactose-free may offer extra benefits in such a way that it will provide alternative recovery drink that can be consumed by lactose intolerant active people.
