Title: Relationship between physical activity and stress level in university students

Abstract:

Background: The purpose of the current survey-based study was to examine the relationship between physical activity and stress level in university students and describe the difference in stress level between sport team students and non-sports team students. Methods: The participants were 243 university students (mean age =21.6, SD = 1.899) from seven universities in Hong Kong. The PA participation was assessed since the last year included exercise frequency, duration and intensity, and the formula was adopted by Fox (1999) and the survey (彭馨穎，2008). The Perceived Stress Questionnaire (PSQ) was used to assess participants' stress level. Results: There was negative correlation between PA participation and stress level (r=-0.486, p<0.01). There was a significant difference of PA participation (p<0.05) between sport team students and non-sport team students, sport team students (M = 36.70 , SD = 14.20) attaining higher PA participation scores than non-sport team students (M = 16.34, SD = 11.08), Also, group comparisons revealed that sport team students reported significantly lower levels of stress than non-sport team students (p<0.05). Conclusions: These findings suggest that students can join sport team to participate in regularly physical activity that may reduce students' stress.

Title: The relationship between the changes of physical activity level during the Covid-19 pandemic and the perceptions of physical demands on return to sport within 4 weeks in aged 21-30 rugby players in Hong Kong

Abstract

The contact nature of rugby with its intensive physical interaction often exposes players to a high risk of injury. Therefore, the rugby environment requires players equipped with high level of strength and conditioning. However, the Hong Kong government compelled all of the sports-association to cancel or postpone their sport activities and programs due to concerns regarding Covid-19 transmission. Consequently, rugby players were not allowed to participate in any on-field rugby training or practice. Instead, the training style has been transformed to be self home-based fitness training. The purpose of this study was to examine the relationship between the changes of rugby players’ physical activity level during the Covid-19 pandemic lockdown period and their perceptions of physical demands on return to rugby participation within 4 weeks. 110 participants aged 21-30 from among eight Hong Kong rugby clubs have participated in this study.

An online questionnaire was distributed to participants in the rugby lockdown period. The questionnaire contained instruments; a) Background information about participants, b) physical activity level before & during pandemic lockdown period, c) perceptions of physical demands of rugby participation for examining their physical condition whether fulfilled the requirements of returning to rugby match within 4 weeks. Respondents were male athletes (n=110). Result showed that most participants trained alone with home-based fitness training (89%), daily (59%) at high intensity (65%) and moderate intensity (69%) respectively, and for 30–60 min (84%). The result has also shown significantly low participation in weight training (37%) during Covid-19 pandemic lockdown period. The majority (62%) expected return to rugby matches after 1-6 months. Moreover, most players reported low motivation on return to rugby matches in a short period of time due to body unwellness, participants need at least one to three months to improve their physical fitness for ensuring their health and wellbeing to prevent injuries.

Covid-19 had physical consequences that may impact 21-30 ages senior rugby players on general fitness and perceived return to rugby matches.

Title: The effect of short-term creatine and carbohydrate intake on male dragon boat player.

Abstract:

Purposes: The present study was to investigate whether immediate and short-term (5 days) creatine intake could enhance the performance of male dragon boat athletes and if so, to assess whether immediate and short-term (5days) additional carbohydrate supplementation could have extra benefit to their performance. Methodology: A total of 20 male dragon boat athletes were randomly assigned into two groups: Creatine group (Group A) and Creatine+ Carbohydrate group (Group B). The time (minute) of individual dragon boat machine test, Heart rate (bpm), The Borg Rating of Perceived Exertion (score 6-20) and blood lactate accumulation (mmol/L) were recorded in both pre and post-test. Results: A significant improvement of their performance of individual dragon boat machine test was found in both group A and group B. However, there is no improvement found in group A in the 1st post-test. Conclusion: In conclusion, dragon boat athlete should consider creatine and carbohydrate intake before the competition in order to enhance performance.

Title: Secondary students’ Physical Activity and Enjoyment Level at Recess with Active Video Game

Abstract

Purpose: The present study aimed to (1) examine secondary students’ physical activity (PA) level during recess with Active Video Game (AVG) play; (2) compare PA levels during normal and AVG-based recess; (3) compare PA and enjoyment level between genders during AVG play; (4) discover the association between PA and enjoyment level during AVG play. Methodology: Participants were 82 students from a secondary school in Hong Kong (mean=14.8, SD=1.9). They participated in an AVG-based recess and a normal recess on the assessment day, both of which lasted 15 minutes. Recess PA levels were measured using accelerometer (ActiGraph GT3X). Minutes in moderate-to-vigorous physical activity (MVPA), light PA and sedentary behavior (SB) were derived using age-specific criteria. Enjoyment level was measured using the revised Physical Activity Enjoyment Scale. Results: AVG-based recess (0.6 minutes) resulted in significantly lesser SB than normal recess (3.5 minutes) (t (81) =8.100, p=.00). AVG-based recess (13.9 minutes) resulted in significantly more MVPA than normal recess (10.3 minutes) (t (81) = -9.387, p=.00). Girls (4.1 minutes) participated in significantly more SB than boys (2.7 minutes) at normal recess (t (77.6) = -2.311, p<0.05). Yet, girls (0.5 minutes) participated in significantly lesser SB than boys (0.8 minutes) at AVG based recess (t (80) = 2.001, p<0.05). Boys (32.4 points) enjoyed playing AVG more than girls (30.5 points) (t (78.155) =2.271, p<0.05). Boys’ light PA was negatively correlated to enjoyment level (r= -.405, p<0.05). Conclusion: When AVG was implemented, MVPA accounted for 92.7% of the recess period (13.9 minutes), which corresponded to one-fourth of adolescent’s daily recommended intake.

Title: The usage of music in physical activities among university students in Hong Kong

Abstract

Nowadays, Hong Kong university students have low physical activity (PA) participation. Studies showed that the majority of university students could not meet the PA guidelines provided by WHO (30 minutes of moderate intensity exercise and five days a week) and there was a positive relationship between music and PA participants. The aim of this study is to examine the usage of music in physical activity among university students in Hong Kong. Specifically, we examine the differences between physical activity participation and use of music among university students with a) different frequency using in physical activity and b) in different genders.

An online questionnaire was conducted to Hong Kong university students among 12 higher education institutions. Participants required to answer the International Physical Activity Questionnaire (IPAQ) and the questionnaire from the Emotional and motivational uses of music in sports and exercise: A questionnaire study among athletes including 32 items (Petri & Lina, 2011), which employed convenience sampling. Hope this research can bring influences to the Hong Kong schools curriculum and increase the PA participation in Hong Kong.

After the data collection, no significant difference was found in the result of most of the research questions. The data showed that the frequency of using music in physical activity participation is not a factor that affect the motivation of physical activity participation; Moreover, the result showed that Energetic and rhythmic music was used more in physical activities among university students, and the habit of the users have differences in low and high physical activity participation; Nevertheless, the result showed that no significant different in use of music between male and female university students. Therefore, music may not be a factor that affect the motivation of physical activity participation of university students.

Title: The motivation of participating in the physical activity of university students in The Education University of Hong Kong

Abstract

Insufficient physical activity has been portrayed as a significant issue in recent years. It is undeniable that most university students fail to fulfill the recommended requirements of participating in 60 minutes or more of moderate-to-vigorous physical activity suggested by the World Health Organization. With acknowledgment of the above factors affecting the motivation of participating in physical activity in Hong Kong, we sought to investigate related information and reasons behind this phenomenon. As such, the purpose of this study was to examine the correlation between physical activity participation and physical activity commitment among EDUHK students studying in different academic years. In this study, the Sport Commitment Model and The International Physical Activity Questionnaires were adapted in order to investigate the motivation of participating in physical activity. Results of this study revealed that the highest motivation construct rated among all subjects was “Sport Enjoyment” whereas the lowest motivation construct was “Other Priorities”. Besides, significant differences were found in five constructs and the questions which had large deviations. The group of Year 3 and Year 4 students have the major difference in the above constructs. Due to COVID-19, participation in physical activity has significantly decreased. It was no denying that there were significant mean differences in frequencies and dimensions for motivation in gender groups. Males are more motivated than females PA participation. In response to these results, it is suggested that relevant efforts should be strengthened to motivate university students who proactively carry out physical activity.
