Effect of gender, carrying and planting the pole on approach step parameters in young pole vaulters

In pole vaulting, take-off speed is considered as a major determinant of performance. Pole carriage could affect the speed acquired during the approach and at the take-off. This study investigated different types of runs performed randomly by young male and female expert athletes: maximal sprint, maximal pole carriage run, maximal run-up with simulated pole plant and competition situation. Speed profile was determined with a radar gun and spatiotemporal parameters were recorded for the last 20 m of the approach with the Optojump Next system. For both genders, mechanical variables were compared using two-way ANOVAs with repeated measurements. Pole carriage represents the main cause of speed decrease for both men (−5.8%) and women (−6.2%). A step rate decrease during pole carriage was pointed out with an increase of contact time for both men and women. Significant speed decrease was observed for women at the take-off compared to pole plant simulation (−4.3%), while not for men. Those results provide a new insight for pole vault training allowing to update training process with specific exercises leading to reduce speed loss at take-off.

Effects of Attentional Withdrawal on Chinese Disabled Biathletes’ Shooting Performance

Under two situations of static empty gun preview and simulated competition, the validity of self-suggestion language “preloading compaction,” which suggests attentional withdrawal, was verified, respectively. Methods. The experiments in the two parts were designed in a single factor group. The participants (Chinese disabled biathletes) fired 20 times (4 groups in total, 5 times in each group) both in pretest and posttest, and they used self-suggestion before each group of firing in posttest. Optoelectronic shooting device based on wireless laser transceiver technology was selected to collect the shooting technical indicators, scores, and other information. The operation evaluation form reflected the subjective feelings of the participants, and the heart rate was measured by the chest band. Results. By the method of big data analysis, under the condition of static empty gun preview, the results showed that there was an extremely significant difference between shooting score and quality of triggering. All the marks on the operation evaluation form improved after the intervention. In the mock competition situation, shooting score has highly significant differences with quality of triggering and relative triggering value and significant difference with aiming ability. The marks of the operation evaluation form have been improved; the heart rate of firing all decreased in different degrees. Conclusions. The attentional withdrawal has positive effects on the shooting scores, technical indicators of optoelectronic shooting device, subjective feelings, and heart rate of disabled biathletes under the two conditions. TIRE (the timing of firing) is the most sensitive indicator and can be used as the focus of future training and scientific research.

Indonesia Sharia Bank Merger Process Reviewed from Business Competition Laws

Islamic bank entities in Indonesia, namely BNI Syariah, BRI Syariah, and Bank Syariah Mandiri have merged to become Bank Syariah Indonesia. The merger process was effective on February 1, 2021. As we know, the three banks are state-owned, which have significant assets and have a reasonably large market in Indonesia. In connection with business competition law which seeks to create a fair business competition situation in Indonesia, every corporate action, including merger activities, must be notified to the Business Competition Supervision Commission (hereinafter as KPPU) to assess whether monopolistic practices or unfair business competition have occurred or not. The notification is an effort to supervise every business actor in order to carry out activities that do not violate business competition and do not harm other parties. This study aims to examine normatively the merger process carried out based on business competition law in Indonesia. The research uses materials from both regulations, legal principles, doctrine, and sources related to the subject matter. The data obtained were then analyzed for further analysis to produce conclusions. The results showed that the merger process between the three Islamic banks in Indonesia did not violate the business competition law because it did not occur in a position monopoly and the absence of monopolistic practices.

Performance Analysis in Olympic Sailors of the Formula Kite Class Using GPS

Formula Kite is an Olympic sport that mainly differs from other kitesurfing modalities for the use of a hydrofoil. It is considered an extreme sport due to the great technical ability required. Regarding performance, the variables that determine performance in a real competition situation have not been studied, and even less so with Olympic sailors. Therefore, the objective of this study was to determine the technical and tactical variables that differentiate elite sailors. The sample consisted of 42 Olympic sailors of the Formula Kite class, who were evaluated in three World Cups. Using a GPS device, the speed, distance traveled, maneuvers, and time spent on the courses of upwind, downwind, and beam reach were recorded. The highest-level sailors presented a higher speed in upwind/downwind/beam reach and a shorter time in upwind and beam reach. Performance seems to be more strongly influenced by technical variables, such as speed, than by tactical variables.

Study on Development Strategy of Tourism Industry in Jiangxi Province Based on Boston Matrix

It has become an important economic development strategy of Jiangxi Province to promote the development of regional economy through the development of tourism industry. However, due to the difficulties brought by the environment and its own limitations, local development is not coordinated and lacks targeted strategies. Based on the development data of tourism industry in Jiangxi Province from 2010 to 2014, 2014 to 2018, this paper constructs the Boston matrix of tourism market in Jiangxi Province, analyzes the competition situation, explains and analyzes the seven changes of the Boston matrix.

How Do the Habitual Sleep Patterns of Elite Female Basketball and Soccer Athletes Compare With the General Population?

Purpose: To compare the habitual sleep of female basketball and soccer athletes to age- and sex-matched controls and to characterize the sleep of basketball and soccer athletes at different competition locations and on the days surrounding competition. Methods: Using an observational case–control design, 41 female participants were recruited to participate, consisting of 11 basketball athletes (mean [SD]: age = 24.1 [4.9] y), 10 soccer athletes (24.8 [6.4] y), and 20 nonathletic controls (24.2 [2.8] y). Sleep was monitored using actigraphy for four 7-day periods throughout the preseason and subsequent competition season. Generalized linear models were used to analyze the effect of group and competition situation (eg, Home or Away) on sleep. Results: During habitual conditions, basketball athletes had longer sleep durations (7.4 [1.5] h) than soccer athletes (7.0 [1.2] h, P < .001) and controls (7.3 [1.2] h, P = .002). During competition, basketball and soccer athletes had longer sleep durations following home (7.7 [1.7] and 7.2 ± 1.3 h) compared with away games (6.8 [1.8] and 7.0 [1.3] h). In addition, basketballers went to bed earlier (23:49 [01:25]) and woke earlier (07:22 [01:59]) following away games compared with soccer athletes (00:10 [01:45] and 08:13 [01:45]). Conclusions: Basketballers had longer habitual sleep durations compared with soccer athletes and nonathletic controls. During competition, basketballers had earlier bed and wake times compared with soccer athletes following away games, highlighting the need for individualized sleep strategies.
