Maintaining proper hydration status is crucial for sports performance and general well- being. Available data show that despite good knowledge in hydration, some elite and collegiate athletes did not practice proper fluid intake to maintain hydration, thus they may have risk of dehydration. Therefore, this study aimed to examine the relationship between hydration status, knowledge and fluid habit among school athletes. This study utilized survey questionnaires to assess hydration knowledge and habit and laboratory equipment to measure hydration status. The findings in this study show that there was no significant correlation (P>0.05) observed among hydration status, hydration knowledge and fluid intake behaviour among the participants. Besides, there were no significant differences (P>0.05) in terms of hydration status, knowledge and fluid intake behaviour between males and female participants. In conclusion, this study provides some new insight with respect to hydration status and knowledge among school athletes.
This study aims to examine whether mild dehydration affects the cognitive function, mood and subjective feelings among the male football players of Universiti Pendidikan Sultan Idris (UPSI). Fourteen athletes with the mean age of 22±1 years, weight of 65.7 ±7.6 kg and height of 168±6 cm were randomly divided into dehydration and euhydration trials. The baseline data was collected a week before the main trials to record the time taken by the participants to lose 2% of the body weight. Fifteen minutes before conducting the trials, the weight, height, pulse rate and urine samples of the participants were collected and then a warm-up session was conducted for ten minutes. The participants were instructed to exercise until mild dehydration by conducting a slow running on a treadmill within forty-five minutes. The participants from the euhydration trial were given drinks every fifteen minutes throughout the experiment, while the dehydration trial were not provided with drinks. A Visual Analogue Scale (VAS) questionnaire was used to determine the subjective feelings of dizziness and thirst, while the cognitive performance was measured by using the Flanker Test. The Profile of Mood State (POMS) questionaire was utilized to measure the mood changes of the participants. Urine Specific Gravity of the urine samples was measured using Digital Refractometer to determine the hydration status of the participants. The data were analysed using the Paired t-test. There was a significant difference in post-exercise body weight loss for the dehydration trial compared to the euhydration trial. In terms of cognitive performance, there was a significant difference for the component of non-congruent reaction time between the dehydration and euhydration trials. Besides, the findings had shown that there were no significant differences for all six dimensions of mood between the trials and there was a significant different for dizziness level between the trials. In conclusion, this study found that mild dehydration has affected the subjective feeling of dizziness and non-congruent reaction time. Thus, the athletes need to be exposed to the fluid intake strategy and the awareness about hydration status in order to avoid dehydration to optimize physical, mental and sports performance.
Kajian ini adalah bertujuan untuk meneliti hubungan antara pengambilan kafein dan tahap keagresifan dalam kalangan atlet Kor SUKSIS. Kajian ini berbentuk kaedah tinjauan dengan menggunakan borang soal selidik berkaitan pengambilan kafein dan tahap keagresifan The Judgements About Moral Behavior in Youth Sport (JAMBYSQ). Peserta kajian terdiri daripada 80 orang atlet sukan berpasukan SUKSIS yang dipilih secara rawak. Data telah dianalisis menggunakan ujian statistik deskriptif, ujian t tidak bersandar dan korelasi Pearson. Hasil kajian mendapati bahawa terdapat perbezaan signifikan (p = 0.014) bagi tahap kekerapan pengambilan kafein antara atlet lelaki (2.00 ± 0.87) dan atlet perempuan (1.50 ± 0.76). Selain itu, bagi tahap keagresifan pula tidak terdapat perbezaan signifikan antara atlet lelaki (3.37 ± 0.60) dan atlet perempuan (3.23 ± 0.66) serta tidak terdapat hubungan yang signifikan antara pengambilan kafein dengan tahap keagresifan semasa bersukan (r = 0.024, n = 80, p =0.831). Kesimpulannya, walaupun kekerapan pengambilan kafein berbeza mengikut jantina tetapi ia tidak mempengaruhi tahap keagresifan dalam kalangan atlet Kor SUKSIS. Oleh itu, terdapat keperluan untuk mengkaji dos kafein yang sesuai yang dapat mencetus tahap keagresifan dalam kalangan atlet
The purpose of rehydration is to replace fluid and electrolyte losses. Carbohydrates and sodium are the main nutrient sources for rehydration. The presence of protein aids the rehydration process and thereby promoting muscle synthesis. Zea mays had been identified as one of the potential food sources that could be an alternative recovery beverage. The aim of this study was to assess the potential of Zea mays (ZM) juice as an alternative rehydration beverage. A total of 15 male participants were involved in this study. They were required to cycle to 70-80% of their age predicted maximum heart rate until they were dehydrated (1.8-2% body weight loss). Then they were given either ZM juice or CE drink in an amount representing 150% of their initial body weight loss. After 4-hours of rest with no other food allowed, their USG and percentage of fluid retention were calculated. Results showed that ZM juice had better retention and demonstrated well hydrated USG readings compared to CE drink. Therefore, ZM juice has the potential to be an alternative rehydration beverage.
Journal of Sports Science and Physical Education 6(1): 1-10, 2017 – 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 post-test. The data obtained was analyzed using a mixed-design ANOVA. The results indicated that there was a significant difference (p
Journal of Sports Science and Physical Education 5(1): 77-94, 2016 - This study aimed to
examine the effectiveness of the Bachelor of Education (Honours) programmes offered by the
Faculty of Sports Science and Coaching in producing quality graduates and their
employability in the profession. Samples for this study comprised of 49 graduates from the B
Ed (Sports Science), 25 graduates from B Ed (Coaching Science) and nine B Ed (Physical
Education) who have graduated from 2010 to 2014 as well as their respective employers and
peers were selected as respondents. Six to ten samples from each programme together with
their employers were interviewed further using guided questionnaire. Data was analysed
descriptively as well as correlation and regression methods. The findings showed that the
graduates mastered very high levels of the knowledge and skills of the courses related to their
respective programmes. They also achieved excellent levels of knowledge and skills in the
implementation of their respective programmes during and after their completion of studies.
The graduates received very high scores from their employers and peers in terms of their
attributes and employability. Overall, analyses on the effectiveness of the faculty‟s education
programmes showed a positive and significant correlation between the mastery (input) and
the implementation (process) of the programmes. However, a moderately positive but not
significant correlation was found between the mastery (input) of the courses and the
graduates (product). Similar results were found between the implementation of the
programmes (process) and the graduates except for the BEd.(Sports Science) which showed a
moderate positive and significant correlation. Only 23% predicted mastery of the course
(input) and the implementation of the programme influenced the product (graduates) towards
the effective implementation of the BEd (Sports Science), compared to 20% for BEd
(Coaching Science) and 98% for BEd (Physical Education). This study concluded that
Bachelor of Education (Honours) programmes offered by the Faculty of Sports Science and
Coaching are capable of producing quality and employable graduates. The faculty has
developed its strategic plan in improving the employability of the graduates by streamlining
the offering of the BEd (Coaching Science) programme, reinforce the undergraduates soft
skills attributes, intensify the activities of the Kinesiology Centre of Excellence and advocate entrepreneurship education in order to produce graduates who are innovative and capable in the education profession.
