Abstract

This research sought to evaluate race strategies in Cross Country running to determine whether a fast, predicted, or slow start would yield the best results when coupled with an advancing or regressing strategy from the 1st checkpoint through to the finish. Twelve National Collegiate Athletic Association (NCAA) Championship races were analyzed from 2021 to 2022 (N=315 teams; 2,205 runners). Success was defined by each team's finish relative to their anticipated finish, as determined through pre-championship national rankings. Results indicated that starting well ahead of a predicted finishing place and advancing throughout the race can yield finishes well ahead of a team's ranking. Still, less than 5 percent of teams could employ that strategy. A more likely positive result came from a conservative start, coupled with consistently advancing through the field for the remainder of the race, as nearly 14 percent of teams could employ that strategy. Starting a race slowly did not typically lead to success, even if a team consistently advanced through the field after the 1st checkpoint. Teams that regressed throughout the race were not likely to have a successful race.

Abstract

Due to a limited number of informative articles available on collegiate rodeo and its athletes, this work aimed to examine the relationship between anthropometric measurements and the physical fitness of rodeo athletes to add to the limited literature focused on the physical profile of rodeo athletes. Within the protocol of university IRB guidelines, 14 (20.86 ± 1.17 years; 178.2 ± 7.85 cm; 86.48 ± 21.39 Kg) male rodeo athletes at a division I school located in the Southwest United States participated in two consecutive six-week resistance training programs. Anthropometric data and fitness performance data from each participating athlete were gathered. The following data were collected: body fat percentage, lean body mass (LBM), vertical jump height, T-test, 300-yard shuttle times, barbell back squat, bench press, trap bar deadlift one repetition maximums (1RMs), single-hand reaction time, and multi-hand reaction time. Research methods included exploratory analysis - including means and standard deviations - to enable a correlational analysis. Descriptive data analysis revealed that the trap bar deadlift 1RM had a significant relationship with the bench press 1RM (r=0.874, p=0.005) and back squat 1RM (r=0.938, p=0.002). Due to limited experience performing resistance training, 1RM performances were possibly based on increased neuromuscular efficiencies – i.e., a 'learning effect.' This study offers new and unique information about the modern rodeo athlete, which can help exercise science practitioners design more efficient training programs.

Abstract

Athletes and coaches strive to identify and learn to use interventions to enhance performance. The goal to be a competent user of psychological skills which aid performance is common among coaches and athletes. However, how frequently such skills are used and how they are learned is less well understood. Many athletes experience plateaus in performance despite efforts to improve, and as such are prime candidates to test interventions to enhance performance. To he present study investigate the effectiveness of learning brief psychological skills among athletes who competed in a weekly 5km time trial whose performances had plateaued. Participants (n = 7) volunteered to follow brief psychological skills training which involved watching brief videos on how to use one of self-talk, reappraisal, if-then plans, or a non-treatment condition, but in the context of the study represent receiving encouragement to mentally prepare. Data analysis compared intervention results with baseline data taken from 2 months of data before the intervention. Results Psychological skills usage associated with finishing 347.37m (p = .019) ahead of baseline. Post-race reflections indicated using psychological skills helped re-appraise fatigue. Findings offer encouraging data on encouraging runners to engage in mental preparation and that following brief psychological skills training is helpful, however, confirmatory research is needed with larger samples.

Abstract

Endurance plays an active role in basketball games as a support for implementing strategy and tactics, so players must have excellent endurance. The study aims to determine the impact of interval training on high school basketball players' endurance. The research applied the experimental method. The samples are ten participants of the As-Shofa basketball team determined through a total sampling technique. The research uses the one-group pretest-posttest design. The instrument in this study is a bleep test. Based on the test analysis, the tcount value obtained was 2,371, and the ttable value obtained was 1,833. These values indicate that the tcount value is greater than the ttable at a 0,05 sig. value. The results of this study can conclude a significant influence of interval training exercises on high school basketball players' endurance. The determinant value of endurance is 67 percent contribution. Thus, high-intensity interval training significantly increases the Vo2max endurance capacity.

Abstract

Wearable technology is novice and beneficial in its ability to retrieve real-time data with minimal hindrance to the performance and mobility of its users. WHOOP fitness band captures physiological metrics and turns them into three metrics: Strain, sleep, and recovery. These metrics allow for personalized monitoring of training metrics to help guide workload. WHOOP bands were distributed to 56 Division II collegiate athletes participating in three sports: Softball (15), women's Lacrosse (15), and Baseball (25). Women's Lacrosse indicated a negative correlation between the hours of sleep players received the day before a game and their respiratory rate during their game (r = -0.55) and a positive correlation between the hours of exercise the day before a game and the respiratory between hours of sleep the day before and respiratory rate the day of the game (r = -0.46) and a moderate negative correlation between hours of exercise the day before a game and the respiratory rate the day of the game (r = -0.55). Baseball indicated a negative correlation between sleep quality the night before the game and duration of exercise the day of the game (r = -0.61). Our examination of performance metrics for three Division II athletic teams using WHOOP fitness straps found that variables differed between teams. Coaches can use WHOOP fitness bands to assist in training and recovering by monitoring pre-game training load, intensity, and sleep.

Abstract

The importance of the research was represented in the preparation of special exercises to develop speed endurance for young handball players, as well as identifying the effect of special exercises in developing speed endurance, passing and shooting performance for handball players. As for the research problem, it was represented in the low level of physical attributes and skillful performance (passing and shooting) from time to time during matches or in their last minutes or in their extra times, if any. As the player becomes in a difficult situation and requires him to perform a high physical and skillful work in front of a low level of speed tolerance, which negatively affects the implementation of his duties at the required speed, especially the attack, which leads to not achieving good results in the match. Accordingly, the researchers set their goals in preparing special exercises to develop speed endurance for young players in handball to develop speed endurance among players. Where the researchers hypothesized that there is a positive effect of special exercises in developing speed endurance, passing and shooting performance for handball players. The researchers concluded that the special exercises were effective in developing speed endurance among the respondents. Which prompted them to recommend the necessity of benefiting from the special exercises in developing the speed endurance characteristic of the junior handball club players, as it is one of the basic physical characteristics in developing offensive skills in handball

Abstract

Without motivation, an athlete will not feel motivated to perform optimally and will be desperate if he fails. The research was conducted to present a motivational relationship between coaches and athletes that describes how coaches can influence athlete motivation. The study was conducted on 62 taekwondo athletes. The instruments to collect data were a motivation scale with 27 items (? = 0.912) and the (CART-Q) Coach-Athlete Relationship Questionnaire with 22 items (? = 0,948). The data analyzed was assisted by the SPSS for Windows version 25. The results obtained from the calculation of the product-moment correlation were the r-value was 0.471, and the r2 value was 0.222, with p lower than 0.001. Thus, there was a relationship between coach-athlete relationship and performance motivation. The psychological processes in which constructive behavior positively influences intrinsic and extrinsic motivations were self-determined by athletes.

Abstract

Sampling frequency of microsensors that measure the position of the players in team sports is a variable that could affect the accuracy of the measurement. The aim of the present study was to assess the impact of the sampling frequency on the measurement of a collective tactical behaviour variable: the total area (TA). Sixteen young U16 male soccer players participated in the study. They carried out three controlled tasks. Tactical variable was measured by a radio ultra-wide band technology (IMU; WIMU PROTM, RealTrack Systems, Almeria, Spain). For TA different sampling frequencies were applied (i.e. 1 Hz, 2 Hz, 4 Hz and 10 Hz). Trivial differences (p more than 0.05) were found between the TA values across the different amounts of inserted data per second across Task 1 (ES= 0.04-0.08), Task 2 (ES= 0.01-0.09) and Task 3 (ES= -0.03-0.04). Also High to perfect ICCs (0.91-1) and linear correlations (r= 0.961-1; p less than 0.01) were found among the TA values obtained through all sampling frequencies. The sampling frequency (i.e. 1 Hz, 2 Hz, 4 Hz and 10 Hz) does not affect the measurement of total area during tactical behaviour analysis but does significantly affect the change in centroid position measurement. Thus, it is recommended the use of 1 Hz to measure TA, but further studies should analyse the impact of lower than 1 Hz and greater than 10 Hz sampling frequencies to measure this collective tactical behavior.

Abstract

In this quantitative study, a bespoke coaching drill was designed and tested over 16 weeks to improve the bowling accuracy of 6 participant seam bowlers. This experiment consisted of 6 male participants with a mean age of 19.5 ± 7.5, mean height (cm) of 184.75 ± 5.57, and mean weight (kg) of 78.05 ± 9.87. Due to the repeated measures experimental design, paired samples t-tests were conducted to assess the effectiveness of this coaching intervention and compare performances between the "control" phase and the "training" phase. Results revealed that this purposely designed coaching drill led to a significant improvement in bowling lines (p less than 0.001) with a moderate effect size and bowling lengths (p less than 0.001) with a large effect size. However, this coaching intervention did not have any significant effect on bowling discipline (p = 0.134). Evidence proves that regular repetition of exercises over a prolonged time can ultimately enhance motor skill refinement. From a practical perspective, coaches can replicate the drill introduced in this study as a means of skill acquisition and skill refinement for their seam bowlers.

Abstract

It has been suggested that grip strength can predict physical fitness in children and adults. The overall plan of this study is to validate this conclusion. The study analyzed the correlation between hand grip strength and sit-and-reach in 70 children aged 6-7 years to gain insight into the correlation between grip strength and sit-and-reach. Descriptive statistics were used in the study to find out the mean scores and differences in these exercises. The correlation between hand grip strength and sit-and-reach flexibility was also explored using Pearson's correlation coefficient. The results showed the correlation coefficient between hand grip strength (mean±sd=5.46±3.75) and sit-and-reach flexibility (mean±sd=8.25±5.28) was 0.078, indicating a weak positive correlation (p more than 0.05). The study's results suggest that grip strength is not a valid predictor of physical dexterity in seated forward bends in the 6-7-year-old children age group. As suggested in previous studies, grip strength can predict physical fitness in children, such as a strong correlation between grip strength and physical flexibility, lung function, muscular endurance, and physical stability. However, from the results, grip strength is not a reliable predictor of physical flexibility. We need to validate further the predictive role of grip strength for other physical fitness indicators. This is a very important validation for us to develop children's physical fitness assessment programs more efficiently in the future.
