Enhancing Training Precision: Unveiling the Barbell Velocity's Role in Tailoring the Resistance Load for the China Badminton Team.

Velocity-based resistance training is a fundamental component of sports science, offering a systematic approach to investigating the load variables of resistance exercises. This research focused on assessing the load across various resistance exercises by examining the barbell velocity during the concentric phase. The study involved 11 male athletes representing the China badminton team, who underwent 1RM testing for bench press, hip thrust, back squat, and single leg press exercises and the maximum repetition testing at load intensities of 60%, 70%, 80%, and 90% of 1RM. Simultaneously, measurements were taken of the barbell's concentric phase velocity during each exercise. The findings revealed a robust negative correlation between barbell velocity and load intensity. Furthermore, exercises engaging greater muscle strength displayed smoother fitting curves. Analysis of velocity loss rates indicated that the hip thrust exhibited a higher completion percentage compared to the back squat and the bench press. Similarly, the non-dominant leg press showed a higher completion percentage than the dominant leg press. The study emphasizes the significance of delineating barbell velocity distributions in resistance training involving large muscle groups, as well as the accurate determination of load intensity. Precise load determination can be facilitated by employing fitting curves derived from distinct movement patterns and varying load intensities. The utilization of velocity data offers a quantifiable approach to achieving targeted training outcomes.

Velocity of nerve conduction of the tibial and peroneal nerves of Jordan's national badminton team

This study aimed to identify velocity of nerve conduction of the tibial and peroneal nerves of the lower end. This was an experimental study and the sample consisted of two groups: the experimental group (A) which consisted of 10 badminton players and their average age was 20-+70 years, regulated in training and every one of them plays with his right hand from the Jordan national badminton team players, and the second, the control group (B), who didn’t practice any physical activity, and their number was (10) who are healthy with average age (20+-60). The results revealed statistically significant differences at ( ≥α 0.05) between the variables velocity of nerve conduction of the tibial nerves and peroneal nerves for the experimental group, there were no statistically significant differences at (≥α 0.05) in the velocity of nerve conduction of the tibial nerves and peroneal nerves according to the variable of age, whereas there were statistically significant differences at ( ≥α 0.05) between the variables velocity of nerve conduction of right peroneal nerves according to the variable of years of experience, where these differences were for people who have experience of more than 5 years.

Evaluating the Effectiveness of Sports Sponsorship from Banking and Financial Services, Case Study: Badminton

Indonesia is known for its badminton success, yet its badminton and sports industry still has fundamental problems in its management, funding, and regulations impacting the athletes' performances. Whereas an athlete's performance is vital for the sponsors as it results in more exposure an athlete can expect to earn for the sponsors' visibility. Therefore, BNI's decision to sponsor the Indonesian badminton team is now arguable whether the company will benefit from this sponsorship deal. Previous research imposed the role of customer perceptions as the determinant of the sponsorship responses that implies the sports sponsorship effectiveness. Thus, the current research is meant to extend the understanding of sports sponsorship effectiveness, specifically from banking and financial institutions in the context of the Indonesian badminton team. The quantitative method through a questionnaire survey was chosen to conduct this research with a purposive sampling technique targeting the non-BNI users who are also the spectators of Indonesian international badminton tournaments in the last 2 years. The descriptive statistics and PLS-SEM were then utilized to analyze the 308 survey responses acquired. The results showed that consumers consider badminton events significant in Indonesia, although not for them. The sponsorship from BNI is also perceived as favorable and matches with the Indonesian badminton team. However, only some variables contribute positively to the sponsorship responses in brand awareness, corporate image, and purchase intention. To gain benefits from sports sponsorship, a company should attract the right target audience while showing real sincerity in sponsoring the sports property. Further research may be extended into other sports and locations of research to explain better the sports sponsorship effectiveness from consumers' perceptions.

The Impact of Some Types of Physical Activity on the Level of Releasing Serotonin Hormone (A Comparative Study)

The current study aimed to identify the impact of practicing some types of physical activity (moderate intensity aerobic exercise, moderate intensity resistance exercise, and moderate intensity badminton) on the level of Serotonin hormone. The researchers adopted the descriptive method as it fits the nature of the study. The study sample consisted of (3) groups: group (A) consisted of Yarmouk University long-distance athletics team players and their number is (5) / males, Group (B) consisted of the Jordanian national weightlifting team players and their number is (5) males and group (C) consisted of Jordan national badminton team players and their number is (5) males. All of the groups are homogeneous concerning age with arithmetic (21.40_+ 3.6). The researchers used the Nag. Blood Test to measure the level of Serotonin among the players before doing any physical activity and after doing the specialized physical activity for an hour. After collecting and analyzing data the results showed an increase in the level of releasing Serotonin hormone between pre-tests and post-tests among players of (aerobic exercise and intensity resistance exercise), where the variances were in favor of the post-measurements. The results also showed that there was no statistically significant increase at the level of releasing Serotonin hormone between the pre-tests and post-tests among the badminton players, and that the rate of increase in the level of releasing Serotonin hormone between the pre-test and the post-test among players of players of aerobic exercises was higher than the one for resistance exercises and badminton, whereas the rate of increase in the level of releasing Serotonin for badminton players was higher than the one for resistance exercises. The researchers recommend the importance of educating community members about the importance of practicing periodic respiratory endurance exercises since they have a major role in improving the level of releasing Serotonin hormone, as well as to conduct studies dealing with high intensity sports to show their impact on releasing Serotonin hormone.
 

Relationships between selected indices of postural stability and sports performance in elite badminton players: Pilot study.

The main aim of this study was to determine the relationships between postural stability and the place in the ranking of badminton players. The study examined 10 elite players from Polish national badminton team. The scope of the study included basic somatic characteristics, such as body height, body weight, BMI, and training experience. A Microgate GYKO inertial sensor system was used to assess the postural stability of athletes. Using Spearman's rank correlation, cause-and-effect relationships between the place in the sports ranking and the analyzed variables characterizing postural stability were recognized. Depending on the distribution and homogeneity of variance, the significance of differences in variables that characterize postural stability between players of different sports skill levels (two groups) was calculated. The Student's t-test or Mann-Whitney's U-test was used for this purpose. In general, the athletes with higher positions on the ranking list presented a higher level of postural stability in both tests, which is also confirmed by the normalized values. However, for all variables of postural stability, no statistically significant correlations with sports ranking were observed. Higher values of Spearman's rank correlation coefficients were found for the test performed in the one-foot standing test compared to the two-foot test. The results obtained indicate that particular attention in badminton training should be paid to the development of the level of postural stability in order to improve sports performance.

APLICAÇÃO DO MÉTODO DE TREINAMENTO SUSPENSO NOS ESPORTISTAS

ABSTRACT Introduction: Suspension training is a new activity in which exercises are performed exploring the body weight as resistance, using a suspension tape. The body remains in constant motion due to the support reaction force formed by the open kinetic chain, requiring rapid muscle contractions for continuous balance adjustment. It is believed that this training can improve proprioceptive neuromuscular function, although there is little scientific evidence of its benefits on body posture in athletes. Objective: Explore the function and application of the overhead training method in athletes. Methods: Sixteen male athletes from a provincial badminton team volunteered for the research. Divided into two groups, the experimental group added suspension training. In contrast, the control group kept only traditional training, the other training contents were the same between the two groups, and the experiment lasted 12 weeks. The relevant data were collected before and after the intervention period by the GoodBalance balance tester, and the balance ability of all athletes with eyes closed on one foot was evaluated. Results: The balance ability of the athletes in the experimental group was significantly improved, while the balance ability of the athletes in the control group changed little. Conclusion: Suspension training can significantly improve the balance ability of athletes and can be used as an effective auxiliary training method for balance improvement. Level of evidence II; Therapeutic studies - investigation of treatment outcomes.

Exploring coaching leadership behaviors among top-division university badminton teams in Taiwan: A “Five Cardinal Relationships” (Wulun) perspective

This study examines coaching leadership behaviors among top-division university badminton teams in Taiwan. Our analytical framework is based on the concepts of Confucianism and its values regarding the behaviors proposed by Mencius that comprise the “Five Cardinal Relationships” (Wulun). As Confucianism is the basis for the Chinese order, Wulun is a unique cultural phenomenon in Chinese society that dominates role norms and duties. A total of 10 relationships based on the relationships associated with Wulun shape the relationship networks of Chinese individuals and thus the behaviors of individual Chinese people. Methodologically, 10 interviews were conducted with two coaches, two player coaching assistants and six players from two first-division university badminton teams in Taiwan. Paternal leadership is a style of leadership associated with authority, discipline, fatherly benevolence and strong morals. First, our results indicate that on Taiwanese sports teams, the leadership behavior of a coach must meet the expectations associated with Wulun relationships. If there is a threat to the image required to play this role, authoritarian leadership becomes the most commonly used style. Second, when a coach consciously demonstrates benevolent and virtuous leadership, relationships have the potential to evolve into friendships. Third, when a coach delegates power to an assistant, the assistant's leadership style becomes rather similar to that of the head coach, thereby maintaining harmony in relationships.

Analysis of Functional Arch Support Insoles on the Biomechanics and Performance in Right-Forward Lunging Step of Badminton Players.

The purpose of this study was to examine the differences in biomechanical parameters and sports-specific performance of lower limbs between arch support insoles (ASI) and flat insoles (FLI) when performing net strides. After installing the MVN IMU system, 18 college badminton team members were asked to take the following tests: (1) Consecutive net stride tests; (2) Six-point footwork tests; (3) Retrieve/stroke the ball at the left and right net; (4) Smash and retrieve/stroke the ball at the net; (5) Smash at the front and back crossover step. The joint angle of the lower limbs and ground reaction force during the support phase was collected. The results demonstrated that the peak right hip flexion angle was significantly greater with ASI than FLI (63.09 ± 10.70; 60.08 ± 13.82; p = 0.028), while the peak right foot inversion angle was significantly smaller with ASI than FLI (20.68 ± 7.87; 23.85 ± 8.11; p = 0.013). The principal conclusion was that the arch support insole avoids the decrease in the hip flexion angle and the increase in the foot inversion angle during the net stride tests.

Newsroom Management of Badminton News Media in Indonesia

The Indonesian National Badminton team is one of the most successful national teams in international competition. Such success has brought a significant contribution to Indonesian national pride. However, in terms of popularity, this sport is less popular when compared to football. Consequently, there are only a few Indonesian sports media that specializes in reporting and discussing badminton. This study aims to determine the newsroom management of badminton media in Indonesia, in particular Majalah Bulutangkis and bulutangkis.com. Newsroom management is an important element in mass media. This study uses the qualitative method, with interviews as data collecting techniques. The informants are editors-in-chief from bulutangkis.com and Majalah Bulutangkis. In general, the results of the study show that both media regularly cover badminton tournaments participated by Indonesian badminton players. News related to events outside the field is also presented, including the side story related to badminton to keep the readers from being bored. From an organizational perspective, both media are experiencing a lack quantity of journalists, so they use freelance contributors or recruit volunteers. In practice, both media use websites as a platform to provide information and the Readers Forum to build interaction with their readers as well as invite readers to submit articles. This condition causes both media to be less active in maintaining their social media accounts. The evaluation stage is carried out by looking at the accuracy of the information and the use of language.

BUILDING UP THE 12-WORK-OUTS TO IMPROVE THE MUSCULAR ENDURANCE FOR MALE BADMINTON TEAM

The purpose of this study was to find out the work-outs to improve the muscular endurance of the male badminton team at Saigon University. Eleven healthy male students in the badminton team at Saigon University were chosen to participate in the 15-week pre-season training program. Four evaluation tests were selected to identify the muscular endurance for male badminton, such as the handgrip strength test, standing high jump test, loaded heavy racket in 30 seconds test, and B endurance test. Twelve work-outs were chosen and applied to the training program. The results indicated that there were significant differences between before and after the experiment (after the application of 12 work-outs) in all evaluation tests. In short, 12 work-outs were highly effective to improve muscular endurance for the male badminton team at Saigon University. Future studies should be applied 12 work-outs in the next pre-season badminton training as well as for female badminton athletes at Saigon University.<p> </p><p><strong> Article visualizations:</strong></p><p><img src="/-counters-/edu_01/0958/a.php" alt="Hit counter" /></p>

The data were statistically handled using the (SPSS) program to obtain (the arithmetic mean, standard deviation, coefficient of variation, simple correlation coefficient, and T-test for independent samples. The researchers concluded: - The variables (horizontal displacement, horizontal velocity and velocity resultant) for BMC in the final phase of the forehand clear stroke skill had a positive significant relationship with accuracy. - The shuttlecock starting velocity in the forehand clear stroke skill had a direct relationship with accuracy. - Accuracy has a direct relationship with variable of the striking arm wrist joint angle and inversely with the forearm angle with the racket variable at the moment of maximum return of the racket in the forehand clear stroke skill. - The relationship was direct between (shoulder angle, forearm angle with the racket) variables (each separately) with the accuracy at the moment of shuttlecock impact in the forehand clear stroke skill. - The increase in the angular deference of the forearm with racket was significantly correlated with accuracy in the main phase of the forehand clear stroke skill. - There is a direct relationship between the angular velocity of the forearm with the racket variable with the accuracy in the main phase of the forehand clear stroke skill. Through the conclusions, the researchers recommend: - The necessity to direct the players to pay attention to the ideal angles of technical performance of badminton skills. - Directing the coaches to use a kinematic analysis programs or seeking the help of an expert and specialist in kinetic analysis to correct some of the players' performance errors that are not seen with the naked eye. - Paying attention to the results of the current study for use by workers in the field of badminton training and education.

Short-Term Effects of Low-Fat Chocolate Milk on Delayed Onset Muscle Soreness and Performance in Players on a Women's University Badminton Team.

This study investigated the short-term effects of low-fat chocolate milk (LFCM) consumption on delayed onset muscle soreness (DOMS) and performance in female badminton players. Seven female badminton players (23 ± 1 years; height: 163.8 ± 4.1 cm; body mass: 58.7 ± 0.9 kg) were randomly assigned to 1 week of LFCM (500 mL) or placebo (water, 500 mL) consumption in a crossover design. Participants consumed LFCM or water immediately after each training session during the 1-week intervention. Performance variables (aerobic power, anaerobic power, agility, explosive power, and maximum handgrip strength) were assessed at two separate time points: pre and post-intervention (after 1 week). In addition, the Visual Analogue Scale (VAS) was used to assess DOMS before, immediately after, and at 24 and 48 h after each training session. There were significant time effects for aerobic power, upper body explosive power, minimum anaerobic power, and time to exhaustion (TTE), which significantly increased after LFCM consumption (p < 0.05). Moreover, relative and maximum lower body power significantly (p < 0.05) increased, while rating of perceived exertion (RPE) as well as DOMS in lower extremity muscles immediately after exercise significantly decreased after LFCM consumption compared to placebo (p < 0.05). There were no significant changes in maximum anaerobic power, agility, and maximum handgrip strength (p > 0.05). LFCM, as a post-exercise beverage, may help speed recovery in female badminton players leading to increased aerobic, anaerobic, and strength performance indices, increased TTE, and decreased muscle soreness and RPE.

Acromio-Humeral Distance Is Associated with Shoulder External Strength in National Elite Badminton Players-A Preliminary Study.

Purpose: To examine acromio-humeral distance (AHD) and shoulder isometric strength for external rotation (ER) and internal rotation (IR) in national elite badminton players. Methods: Seven elite badminton players with asymptomatic shoulders aged 24 ± 4 (mean ± SD) from the Danish national badminton team were investigated. Shoulder AHD, isometric strength in ER and IR were bilaterally assessed with ultrasonography and a hand-held dynamometer (HHD). Results: AHD was greater on the dominant vs. the nondominant side (p = 0.018). Moreover, IR strength was greater on the dominant side vs. the nondominant side (p = 0.041). Furthermore, AHD and ER strength were highly correlated on the dominant side (p = 0.007, r = 0.900). A correlation was also shown between AHD and the ER/IR strength ratio on the dominant side (p = 0.033, r = 0.793). Conclusion: This preliminary study demonstrates that shoulder ER strength is strongly associated with AHD size, largely reflecting supraspinatus tendon-muscle hypertrophy as a result of sport-specific adaptation in national elite badminton players with asymptomatic shoulders. These novel data also suggest that habitual loading of the shoulder improves the supraspinatus tendon size, which may lower the mechanical stress and potentially reduce the risk of injury. This warrants strengthening the shoulder external rotators as a potential strategy to reduce the risk of future shoulder injury.

ShuttleSpace: Exploring and Analyzing Movement Trajectory in Immersive Visualization

We present ShuttleSpace, an immersive analytics system to assist experts in analyzing trajectory data in badminton. Trajectories in sports, such as the movement of players and balls, contain rich information on player behavior and thus have been widely analyzed by coaches and analysts to improve the players' performance. However, existing visual analytics systems often present the trajectories in court diagrams that are abstractions of reality, thereby causing difficulty for the experts to imagine the situation on the court and understand why the player acted in a certain way. With recent developments in immersive technologies, such as virtual reality (VR), experts gradually have the opportunity to see, feel, explore, and understand these 3D trajectories from the player's perspective. Yet, few research has studied how to support immersive analysis of sports data from such a perspective. Specific challenges are rooted in data presentation (e.g., how to seamlessly combine 2D and 3D visualizations) and interaction (e.g., how to naturally interact with data without keyboard and mouse) in VR. To address these challenges, we have worked closely with domain experts who have worked for a top national badminton team to design ShuttleSpace. Our system leverages 1) the peripheral vision to combine the 2D and 3D visualizations and 2) the VR controller to support natural interactions via a stroke metaphor. We demonstrate the effectiveness of ShuttleSpace through three case studies conducted by the experts with useful insights. We further conduct interviews with the experts whose feedback confirms that our first-person immersive analytics system is suitable and useful for analyzing badminton data.

Morning Heart Rate Variability as an Indication of Fatigue Status in Badminton Players during a Training Camp.

This study aimed to clarify whether changes in the fatigue status of elite athletes during a precompetition period could be evaluated using morning heart rate variability (HRV) indices. Eight Japanese National Badminton Team players (age, 23.0 ± 2.8 years) participated in this study. HRV and subjective fatigue were measured during the first (days 1–4: Phase 1) and the second half (days 5–8: Phase 2) of an 8-day national team training camp. The global and parasympathetic HRV indices were as follows: standard deviation of all R-R intervals (SDNN) (Phase 1, 87.5 ms; Phase 2, 104.3 ms; p < 0.05), root mean square of the successive R-R interval differences (RMSSD) (Phase 1, 66.6 ms; Phase 2, 103.6 ms; p < 0.05), and high-frequency component power (HF) (Phase 1, 1412.0 ms2; Phase 2, 3318.5 ms2; p < 0.05). All the aforementioned indices increased significantly from Phase 1 to Phase 2. Significant correlations were observed between the change in subjective fatigue and changes in SDNN, RMSSD, and HF (ρ = −0.80, p = 0.017; ρ = −0.77, p = 0.027; and ρ = −0.80, p = 0.017, respectively). Measuring morning HRV indices may be effective for objectively evaluating changes in the fatigue status of elite athletes during a precompetition period.
