Coincidence anticipation timing requirements across different stimulus speeds in various sports: A pilot study

ABSTRACT

The ability of coincidence anticipation timing is directly related to athletic performance in sports, and anticipation timing requirements vary according to the sports type. This case study aimed to investigate the coincidence anticipation timing of male university athletes in various sports across different stimulus speeds such as slow (3 mph), moderate (6 mph), and fast (9 mph). Nineteen university athletes from soccer (n = 5), tennis (n = 7), and volleyball (n = 7) participated voluntarily in this study and were compared to non-athletes (n = 6). All participants pressed the button when the light stimulus arrived at the target location of a Bassin anticipation timer to assess anticipation timing accuracy in terms of constant, absolute, and variable errors. A speed effect in constant error (p < 0.001) and a group by speed interaction in variable error (p = 0.044) were found. However, no significant difference was found in absolute error. In conclusion, coincidence anticipation timing requirements are different across sports types. Racket sports such as tennis might be more beneficial to improving anticipation timing skills than other sports or non-athletes.

Coach experiences during a pandemic: Navigating change in a challenging environment

ABSTRACT

The purpose of this study was to understand coaches’ response via their day-to-day experiences during the COVID-19 pandemic from the lens of coaching during the COVID-19 national health pandemic. This study utilized qualitative analysis via two zoom-call recorded interviews. A total of nine current head coaches (middle and high school) of teams that participated in the 2021 spring season were involved. Data were analyzed using standard interpretive techniques. Final analysis resulted in general themes that reflected perceptions of the coaches. Themes included (a) new purpose, (b) extra preparation, (c) mixed emotions, (d) creating connections during isolation, and (e) finding relief in helping hands. Coaches are faced with challenges each season. With the recent COVID-19 pandemic, coaches experienced difficulties never seen before. Coaches learned to adapt and respond to situations with a goal of togetherness as a team and competing again. These experiences will prepare coaches for future unexpected changes that can occur within a typical sport season.

Associations between game outcome, game location, and wellness in Division I women’s lacrosse athletes

Abstract

PURPOSE: Athlete wellness—a subjective measure assessing the response to the previous day’s physiological and psychological stress—has subsequent influence on the day’s performance. Game location (i.e., home, away) is also believed to influence performance and game outcome. The purpose of this study was to determine if game location and game day wellness were related to game outcome for a collegiate women’s lacrosse team. METHODS: Athletes (n = 34) completed a daily subjective wellness survey each morning. The survey consisted of questions related to muscle soreness, sleep quality, stress, and fatigue, with responses rated in arbitrary units (AU) using the anchors of 0, 25, 50, 75, and 100, and higher scores represented positive affect. The scores of each of the four responses were averaged to calculate the overall wellness score. Individual athlete wellness scores were categorized as above or below the team mean for each game. A chi-square analysis was used to evaluate the relationship between the wellness variables and game location with the game outcome. RESULTS: The season consisted of seven losses and nine wins, with 10 games played at an away location and six games played at home. Location was not related to game outcome (p = .152), nor were any of the game day wellness sub-scores or composite score (wellness: 71.4 ± 2.7 AU, p = .614; muscle soreness: 63.8 ± 2.9 AU, p = .527; sleep: 83.0 ± 3.4 AU, p = .527; energy: 80.0 ± 1.5 AU, p = .490; stress: 65.0 ± 4.7 AU, p = .490). CONCLUSIONS: Game location, and game day wellness were not related to game outcome in Division I women’s lacrosse athletes. These findings refute previous beliefs regarding the importance of “home field advantage.” Further exploration regarding sleep quality differences in relation to game location and subsequent game outcome are warranted. APPLICATION IN SPORT: Coaches and athletes can use this information to refute previously believed notions about advantages to playing home games. Coaches can work with their athletes to ensure similar pre-game preparation on and off the field for optimal performance.

The morphological age and weighted evaluation of the neuromuscular qualities of the young player

ABSTRACT

This study aims to answer some questions concerning the aspects relating to the anthropometric and neuromuscular evaluation of the young football player.
Objectives: The points on which we try to clarify are: 1- seek an indirect criterion for determining the biological age that complements and integrates the one most, to date, adopted proposed in 2002 by Mirwald et al. (22), based on the determination of PHV and APHV, since this would seem quite reliable with subjects with normal maturation but not so much when they are late or early; 2- determine for each chronological age and for each of the tests used in the study the Gold Standard Range Improvement (GSRI) expected to know if, basically, a detected improvement can be considered Regular Improvement, i.e. attributable to the normal physical maturation process rather than Irregular Improvement, that is attributable to other factors such as training; 3-identify the ABAEI (Age Best Average Expected Improvement) of jumping ability (CMJF), 20m sprint ability and agility ability to verify the actual presence of one or more favourable moments, between 7 and 17 years , where it is easier to achieve significant improvement; 4- provide a sufficiently reliable method to interpret the results of the neuromuscular tests considered in the study without these being influenced by the degree of maturation; 5- understand if the selection criteria adopted, in a professional context such as the one we have observed, tend to favour individuals with early maturation.
Materials and methods: A sample of 827 footballers aged 7-17 and belonging to the youth sector of a professional Swiss super league club, was subjected to a longitudinal analysis, relating to some anthropometric measures (weight, height, chronological age, BMI) together with the results of three field tests (CMJF, sprint on 20m and agility). For the indirect determination of the biological age, a model was developed with which to calculate the morphological age on young players who train regularly, therefore on average thin, normal weight, starting from the measurement (twice a year) of weight, height, chronological age and BMI.
Results: From the analysis of the data, it emerged that the observed sample was found to be on average early since it reached PHV at least one year earlier than what is reported in the literature by Parizkova in 1976 and Malina et al. in 1999 (19,13). In the 7–17-year period, the average performance improvement of each of the tests administered was significant and constant (2.8% -12.8% for CMJF; 2.2% -6.4% agility; 2.02% -6.48% sprint 20m). However, CMJF and sprint 20m provided the same ABAEI (8-9 years) while for agility the ABAEI seems to coincide with the 9–10-year period. The GSRI was calculated for each age and for each of the tests considered in order to provide field technicians with a reference range that allows them to check whether the improvement obtained by their children can be classified as Regular or Irregular Improvement.
Conclusion: The analysis of the results allows us to make some interesting considerations: first, there is a tendency to favour subjects with early maturation. Starting from simple anthropometric measures, it is possible to calculate a further indirect indicator of maturation, the here proposed morphological age. Since this together with the determination of the PHV can help us to approach the biological maturation of young players and to weight the test results in relation to the degree of maturation. Finally, the ability to jump acceleration on 20m and agility naturally improve during the whole period 7-17 even if with differences depending on the age. While for the CMJF and for the agility there are no evident variations in the percentage of improvement, for the acceleration capacity the period between 8-11 years and that between 14-16 years seem to be more sensitive to improvement.

Effect of Shoulder and Hand Position on Sport-Specific Grip Force in Rock Climbers

Abstract

Purpose: Rock climbing has become popular as a recreational activity. Overuse injuries of fingers and hands are common due to uniquely high demands placed on these structures. Climbers adapt hand positions to match types of holds on rock climbing routes, with open-hand and half-crimp positions being most used. The primary purpose of this study was to explore differences in climbing-specific grip strength between 2 hand positions and 2 shoulder positions. Methods: Participants’ maximum isometric pull was tested on a 20mm edge climbing hold attached to a force transducer in each of 4 hand/shoulder position combinations bilaterally. 46 participants (20 female) across skill levels were included for analysis. Peak force was extracted and normalized to participants’ body weight. Mixed model ANOVAs were used to explore effects and interactions between shoulder position, hand position and skill level. Paired t-tests were used explore asymmetry between dominant and non-dominant hands. Results: Half-crimp position was stronger than open-hand position and shoulder position did not impact force production. Climbers of higher skill level had higher force production in both hand positions. Greater asymmetry was observed in climbers of higher skill in the half-crimp position only.

Conclusion: Findings support using a single shoulder position for testing finger strength versus multiple positions. Climbers of all levels should emphasize both open-hand and half-crimp training for performance and injury prevention. Applications in Sport: Shoulder position did not impact force in open-hand or half-crimp grip. Higher skill climbers produced greater force. Force was higher in half-crimp versus open-hand positions independent of skill. Climbers use open-hand and half-crimp positions and should train both for performance and injury prevention. Strength testing could include a single shoulder angle for efficiency.
