Title: The Effects of a 6-week compound leg training on body composition and balance ability among teenagers in Hong Kong

Abstract

Low physical level’s teenagers with muscle weakness and loss of balance are prone to experiencing accidents and injuries. Deficits in strength of lower body had been related with a high risk of injury and such injury happens during physical education lesson. Purpose: The study objective is to examine the effects of 6-week compound leg training program on body composition and balance ability among teenagers. Method: A total of 20 participants between 20-27 years old joined for the study. 20 volunteers participate in this study assigned to two group (intervention and control group. Intervention group (5 male and 5 female) followed the 6-weeks leg training program and the control group (5 male and 5 female) followed their original lifestyle. Before the research, all participants are told to calculate their height and weight to evaluate their body mass index. After calculated the body index, all participants are told to have a BESS test (Balance Error Scoring System) with single-leg and both leg on the ground and a foam balance pad. Result: The result from the 6-week leg compound training showed the significant improvement on the balance ability and body composition among teenagers. Conclusion: The results implicate that leg compound training is benefit for enhancing body composition and balance ability in teenagers. Building muscle and maintaining balance is important for daily activities for all people especially teenagers with lower levels of physical fitness.

Title: Effect of 8-week weight training program on rope skipping performance of continuous double under

Abstract

Background: Rope skipping is an aerobic sport, one of the tricks called double under has been used by many athletes because of the endurance characteristics. As weight training could improve in endurance sports, it may also effective in double under. Purpose: This study was to examine the effect of an 8-week weight training program on rope skipping performance in secondary school students. Methods: Forty secondary school students were recruited in the study and be divided into two groups: an experimental group (EXP) (n=20) and a control group (CON) (n=20). Both groups continued their normal training, while the EXP attended two additional weight training sessions per week for 8 weeks. All participants were examined in pre-test and post-test using rope skipping continuous double under test (DUT), push-ups test (PUT), sit-ups test (SUT), and repeated squat test (RST). Results: Compared with the pre-test, there were significant improvements in post-test DUT (71.9 ± 29.2 vs. 104.9 ± 30.1, p = 0.029), PUT (35.9 ± 7.4 vs. 43.6 ± 6.3, p = 0.029), SUT (28.7 ± 8.6 vs. 45.1 ± 8.4, p = 0.001), and RST (36.9 ± 5.2 vs. 44.9 ± 5.3, p = 0.00) in EXP. Conclusion: These results show that an 8-week weight training program may improve performance of continuous double under and muscular endurance in secondary students. (217 words)

Title: Compare the balance ability those who are non-sport team's members & those who are sport team's members in EdUHK

Abstract

This study is about comparing the balance ability of non-sport team’s members and sport team’s members of The Education University of Hong Kong (EdUHK). It shows the growth of balance ability in sports at the same time. Target group of the study is seventy (male n=35, female n=35, sport team n=30, non-sport team n=40). The study contains pre-test, exercise and post-test. The pre-test and post-test are the same assessment which are 2 static assessments and 3 dynamic assessments. In between, the subjects have to complete a 3 weeks exercises program. The data shown that sport team’s members have better balance ability in both static and dynamic performance. For the static assessments, half of the non-sport team’s members could perform level 4 or 5, and the rest of the members have the range in level 2 to 3. Basically over 90% of the sport team’s members could perform level 4 to 5. In the dynamic assessments, the result has significant different where sport team’s members performed less error and faster in completing assessment. After the training program intervention, the data and result are similar as the pre-test. However, the growth rate are different where non-sport team’s members have a higher growth rate. According to the hypothesis, sport team’s members have a better balance ability compare with non-sport team’s members and the growth rate of non-sport team’s members will be higher than sport team’s members. The data basically matched the hypothesis of the study. The data leads to further study and discuss about the relationship between injury prevention and balance ability by adding leg muscle strength into the assessment.

Title: How would daily practice of motor skills affect the sports performance of youth basketball players

Abstract:

Background: Nowadays, basketball has been developed to a new different kind of style of sport. Since the rise of Stephen Curry and the Golden States Warriors, basketball has become smaller, and is no longer a sport that demands physicality and endless power. Modern basketball requires players to be more agile, skillful, body control and focus on the details. The training also evolved due to the switch of a new style of basketball. Purpose: Examine the impact of motor skill training on improving body coordination, balance, agility and reaction time among amateur basketball players. Methods:20 local male amateur basketball players (16-25) will be allocated into the experimental (10 in experimental group(E)(mean ± SD: age22.9 ± 1.91years ;height 178.9 ± 7.00 cm; weight 81.5 ± 12.3 kg) and control groups (10 in control group(C)(mean ± SD: age24.3 ± 1.50years ;height 176.5 ± 4.12 cm; weight 84.4 ± 11.0 kg). Each group has regular practices or participates in basketball games. They will do a pretest to examine their level of balance, body coordination, hand-eye coordination. Then the experimental group will do a given task to practice their motor skills daily for 3 weeks long. Analysis: outcome variables will be compared among two groups by independent-samples t-tests. Results: An independent-sample t-test was conducted to compare the balance and hand-eyes coordination for amateur basketball players who divided into experimental and control groups. There was significant differences in single leg stance for E (M=3.2, SD=2.66) and C (M=0.6, SD= 1.43) and hand wall toss (E, M=-7.5, SD= 7.66) (C, M=1.7, SD = 3.65). Conclusion: Motor skills training can improve basketball players sports performance by enhancing their body coordination, balance, agility.

Title: Sports Injury Patterns and Injury Risk Factors among Hong Kong University Athletes

Abstract:

AIMS: This cross-sectional study aimed to investigate sports injury patterns and injury risk factors among a sample of university sports teams students in Hong Kong and to compare the sports injury patterns and injury risk factors among genders, different BMI classification groups, and comparison of contact and non-contact sports respectively.

METHODS: 304 university sports teams students were invited to the current study. Participants are asked to fill in an online questionnaire, in order to access the history of sports injury and sports injury risk factors in the past 12 months. Subjects would be regrouped into three compared groups: genders, contact or non-contact sports, and BMI classification groups. SPSS statistics 26 was used for data analysis. Independent-Sample T-Test was used to test genders and contact or non-contact sports. One-way ANOVA was used to test BMI classification groups.

RESULTS: There are three compared groups which are genders, BMI classification groups, and sports groups (contact and non-contact). The distribution of subjects in terms of genders was 56.6% male (n=172) and 43.4% female (n=132). There is no significant difference in duration of recovery and number of injuries in 12 months between gender groups. (P=0.456> 0.05)(P=0.234 >0.05)

The distribution of subjects in terms of BMI classification groups was 22.7% underweight (n=69), 58.6% normal (n=178) and 18.8% overweight (n=57). There was a significant difference in the number of injuries between normal and overweight groups (P=0.031>0.05). There was no significant difference in duration of recovery among underweight, normal and overweight groups (P=0.497>0.05). There was no significant difference in the personality, external factors and self-monitoring among underweight, normal and overweight groups.

The distribution of subjects in terms of sports type was sport groups was 46.6% of contact sports (n=141) and 53.4% of non-contact sports (n=163). There was no significant difference in the personality and self-monitoring between sport groups (P=0.456 >0.05) (P=0.306>0.05). There was a significant difference in external factors between sport groups (P=0.00<0.05).

There were significant differences between personality and self-monitoring among the genders (P=0.07<0.05) (P=0.09<0.05). There was no significant difference in external factors among the genders(P=0.092>0.05).

CONCLUSIONS: The risk factor in gender was personality and self-monitoring. The risk factors in sport groups are external factors.
