Purposeful Practice: Constraints and Temperament Impact on Physical Performance of Collegiate Division II Soccer Athletes

Abstract

This quantitative quasi-experimental study examined differences in mean and median differences of millennial soccer athlete’s performance. Research indicates that millennials struggle with complex tasks due to their fear of failure. Individual productivity has been shown to be positively influenced by the use of designed constraints. The study employed the C-BMN framework and the GPAI to analyze data pertaining to constraint-type and its influence on the productivity of 18 soccer players. Individual components teamwork and trapping showed statistical significance during the intervention, while positioning, passing, and dribbling did not. The overall GPAI showed statistical significance between the control and both constraint types. A two-mixed ANOVA showed no statistically significant interaction between constraints and temperaments however only 72% of participants completed the temperament assessment.

Reliability of a Point-of-Care Device for Saliva Analysis During Aerobic Exercise

Abstract

Salivary alpha-amylase (sAA) and Cortisol (C) have been of increasing focus as biomarkers for monitoring acute and chronic stress. Recently there has been an interest in improving point-of-care devices to increase practicality of salivary testing and remove the need for laboratory analysis. A new point-of-care device has been reported to be highly reliable during baseline testing but has yet to be proven reliable up to the expected concentrations from intense exercise (exceeding 1000 U/mL). Following a modified graded exercise test (GXT) which consisted of sAA and C analysis at baseline, 50-, 70-, and 90-percent of heart rate max, the new point-of-care device showed strong to very strong reliability across the concentration spectrum (sAA: r = 0.60; C: r = 0.73). According to the results of this study, this point-of-care device is able to assist the coaching staff in making training decisions based off of the results provided.

Which global tennis rating better measures player skill? Evidence from the 2022 USTA Junior National Championships

ABSTRACT

Assessing relative player skill is important in many aspects of tennis. In 2008, the Universal Tennis Rating (UTR) was introduced as a global tennis player skill rating that put all players, regardless of gender, age or geographic location, on a common scale. The International Tennis Federation (ITF) recently launched a competitor rating called the World Tennis Number (WTN). The purpose of this paper is to provide evidence on which rating is a superior measure of player skill. We assume better skilled players are more likely to win tennis matches and examine whether UTR or WTN ratings better predict head-to-head match success using 1,532 matches played by 870 participants at the 2022 United States Tennis Association (USTA) Junior National Championships. We observe classification accuracy of 73.9% and 70.4% for UTR and WTN ratings, respectively. Both classification accuracy levels are statistically greater than chance and approximate the accuracy level observed for bookmakers at the professional level. UTR and WTN rating classification accuracy does not statistically differ between ratings in the sample overall, by age division, by gender, by match format, or by the magnitude of player rating differences. We conclude that UTR and WTN ratings are equivalent measures of player skill based upon their ability to predict match outcomes. These findings provide initial empirical evidence important to tennis organizations making rating adoption decisions, tennis coaches seeking play parity, tournament directors seeding players and college coaches screening potential recruits. We provide mapping functions between UTR and WTN ratings for situations where players have one rating but not the other.

Return to Play and Learn: Findings from a Countywide High School Sports-Related Concussion Program

ABSTRACT

Purpose
To report return to play (RTP) and learn (RTL) findings of high school athletes with a sports-related concussion (SRC) from a 10-year injury surveillance system. The goal was also to explore differences between athletes who received and did not receive academic accommodations.

Methods

SRC data was entered into a REDCap database by certified athletic trainers (ATs) at 35 public high schools in Miami-Dade County (MDC). A required 6 Steps to Safe Play concussion protocol was implemented between 2012 to 2022. Concussion Clinic data was also reported for as well as symptom scores of post-injury ImPACT retesting.

Results

From review and analysis of the ImPACT retesting scores, the most common symptoms reported included; headache (54.0%), difficulty concentrating (35.0%), sensitivity to light (34.6%), and dizziness (30.5%). Overall, female athletes reported a higher symptom count and severity on post-injury ImPACT assessments than males (7 vs. 4 total symptoms score; p < 0.001), and all but 4 of the 22 reportable symptoms listed on the symptom inventory (vomiting, fatigue, numbness/tingling, and difficulty remembering) were significant (p < 0.05) between males and females. Despite experiencing a greater number of overall SRCs, athletes playing football had a smaller average (p < 0.001) ImPACT total symptom score than athletes playing other sports (10.9 vs. 14.2). Those seen in clinic and receiving academic accommodations were less likely to RTP, have a greater (p < 0.05) ImPACT total symptom score, more days between injury date and post-ImPACT testing, and a greater number of days until returning to play than athletes not academically accommodated.

Conclusions

It is important for concussion providers to identify and monitor symptoms post-SRC. Study findings report that high school female athletes report more symptoms following an SRC and that appropriate academic accommodations should be included when necessary to ensure athletes recover in a safe and timely manner. Understanding how SRC symptoms vary based on an athlete’s circumstances can help in managing SRC and making better RTL and RTL decisions.

Application In Sports

Academic accommodations, when appropriate, should be incorporated and implemented in an athlete’s recovery plan to help them safely return to the field and classroom after an SRC.

Key Words: Concussion, Adolescent, Accommodations, Symptoms

Visual Memory Recovery by Gender in Young Athletes with a Sport-Related Concussion (SRC)

Abstract

Objective: This study aimed to determine 1) whether there are gender differences in the post-concussion (PC 1-3) recovery process in visual memory after a concussion, and 2) whether there is interaction between two gender groups and the number of concussions.

Method: 75 athletes with sports-related concussion in two groups by gender. The Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT) performance was compared between and within subjects from post-concussion test 1 (PC1) to PC3. The visual memory composite scores were obtained from ImPACT.

Results: Two gender groups were significantly different in visual memory: female athletes were higher than male athletes in visual memory composite scores. Two gender groups also exhibited different recovery pattern: female group showed early recovery from PC1 to PC2 as well as from PC1 to PC3, while male athletes showed significant recovery from PC1 to PC3 only. There was no significant interaction between visual memory scores and the number of concussions.

Conclusions: We can conclude that two gender groups differed in visual memory composite scores. Additionally, the timing of the recovery was different by gender. There was no interaction between the visual memory scores and the number of concussions sustained.
