Performance Differences in Division III Female Field Hockey Athletes with Prior Lower Extremity Injuries Over a Competitive Season

ABSTRACT

Background: In the sport of field hockey, athletes encounter repetitive unilateral movements due to the nature of the sport, possibly leading to detectable changes in performance variables or functional movements.

Purpose: The purpose of this study was to first investigate pre-season power output, functional movement, and single leg balance differences in participants with a history of prior lower extremity injuries, and second, to examine potential changes in such measures throughout a competitive field hockey season.

Methods: Eighteen healthy collegiate female field hockey athletes (mean age = 19.3 ± 1.2 years) were assessed in different functional movement and performance measures including the Functional Movement Screen (FMS^TM)deep squat, Y-balance anterior reach test (YBT), lumbar-locked thoracic rotation test (LLR), vertical jump, and a single-leg eyes-closed balance test pre- and post-competitive season.

Results: Fourteen participants completed the study. Preseason testing revealed a significantly lower peak concentric rate of force development (RFD) in those reporting previous injuries of the lower extremities compared to those with no prior injuries (p = 0.017, d = 1.37). No differences were noted post-season in previously injured participants. Post-season testing revealed a significant decrease in LLR (Left: p = 0.004, d = 0.35; Right: p = 0.007, d = 0.33), a decrease in multiple single-leg balance measures (center of pressure excursion: Left: p < .0005, d = -0.7; Right: p < .0005, d = -1.1; medial/lateral velocity: Left: p < .001, d = -0.24; Right: p < .0005, d = -0.74; anterior/posterior velocity: Left: p < .0005, d = -1.06; Right: p < .0005, d = -1.18) and a decrease in peak concentric rate of force development (RFD) (p = 0.03, d = .33). There were no significant changes noted in post-season FMS^TM deep squat scores, or YBT results among the participants.

Conclusion: Female field hockey athletes with a history of lower extremity injuries demonstrate significantly less concentric RFD during a vertical jump when compared to athletes with no prior injuries. Thoracic ROM, single-leg balance performance, and concentric RFD all significantly decreased after a competitive Division III collegiate season. FMS^TM deep squat and YBT anterior reach scores did not change throughout the season.

Applications in Sport: Field hockey athletes with a history of previous lower extremity injuries should continually focus on power development, while thoracic ROM exercises, single-leg balance training and lower body explosive exercises should be a point of focus for female field hockey athletes to maintain preseason values throughout a competitive season.

The Role of Organized Youth Sports in Reducing Trends in Childhood Obesity

Abstract

Purpose: To examine physical activity (PA) levels of children playing youth sports and the relationship of recommended levels of PA to contextual factors of the organized youth sports environment that may boost fitness and health during childhood and adolescence. Methods: Accelerometer-measured PA was obtained from 167 children (85 male, 82 female) aged 7-13 years. Sport contextual factors were recorded via direct observation of 29 coaches. PA levels were examined by age, gender, and between group variability. Direct observation intervals were analyzed by category using the Chi-square statistic for degree of association to moderate-to vigorous-intensity physical activity (MVPA). Results: On average children spent 21.9 ±7.9 minutes in MVPA during sport practices (< 50% of practice time). Proportion of practice time MVPA was lower among females (28.7 ± 7.2%) than males (35.0 ± 9.1%). Proportion of practice time MVPA was higher among children (male and female) aged 7-9 years (32.6 ± 1.4%) compared to children aged 10-13 years (30.66 ±1.25%). Longer practice times were not shown to increase the proportion of time spent in MVPA. The most frequently observed sport activities were sports drills (51.6%), activities involving all players (37.8%), management/general instruction (52.3%), and proximal positioning of the coach (99.5%). Management and general instruction coaching behavior was not significantly associated with MVPA but did consume a prominent proportion of practice time. Health-related fitness activities made up 1.7% of practice time. Conclusions: In comparison with recommendations, youth sports appear active, however, a large portion of practice time is sedentary suggesting room for improvement. Including fun non-specific or specific sport activities that promote participation from all players and increase heart rate. Fun play experiences during sport practices may encourage greater in active play within and outside of sport with behaviors persisting into adolescence and adulthood. Applications in Sport: Training coaches to teach fun sport activities that engage all players would improve within practice active time and enjoyable experiences that may promote future participation in sport or activity outside of sport.

Weight Discrimination among Students from a Diverse Urban University

ABSTRACT

Purpose: To examine the association between university students’ weight discrimination and their academic discipline, gender, ethnicity, body mass index (BMI), body fat percentage, explicit overweight bias, personal body perceptions, and their personal experiences with weight loss. Methods: Sixty-two students (Age: 23.9 ± 4.7 y) from various disciplines completed 1) a 41-question survey that addressed the participant’s explicit overweight bias, prior struggles with body weight, and body perceptions; 2) the Weight-Implicit Association Test (WIAT) to address overweight implicit bias; and 3) measurement of height, weight, and body fat. Chi-Square tests were performed between the participant’s WIAT results and academic discipline, BMI, body fat, explicit bias, personal experience with their body fat, and body perception. Moreover, differences in BMI and body fat percentage were examined with two separate 2 (gender) × 2 (academic discipline) repeated measures ANOVAs. Results: ANOVA results revealed a relationship between an explicit bias and WIAT implicit bias. No relationships were found between the results of the WIAT and academic discipline, BMI classification, body fat classification, personal experience with body fat, or perceptions of their body. Conclusions: An implicit anti-fat bias exists regardless of academic discipline, percent body fat, BMI, explicit anti-fat bias, prior struggles with body fat, or perceptions of their body. These findings support previous literature that suggests individuals have an unconscious negative prejudgment of overweight people. Applications in Sport: Current physical educators, healthcare professionals, fitness professionals, sport coaches, and university faculty preparing students for these professions must begin to take the steps necessary to eliminate weight bias from their environments. The authors recommend that all members of the aforementioned communities develop an understanding of the factors that may lead to weight gain and develop strategies of encouraging overweight individuals to reduce their weight without further perpetuating weight stigma.

Health and Lifestyle Behaviors of U.S. Masters World Cup Field Hockey Players

ABSTRACT

The purpose of this study was to examine health and lifestyle behaviors of United States Masters field hockey athletes who competed in the Masters Field Hockey World Cup in 2018. A total of 122 athletes (72 women, 50 men) completed the 42-item Health and Well-being of Masters Field Hockey Athletes Survey. Mean age was 50.1±8.3 years (range = 35 to 71). Mean body mass index (BMI) was 24.9±3.1 kg/m². Participants rated their health as very good/excellent (86.9%) and their stress as rare/not at all (56.6%), had no major health conditions (61.5%) or medication use (70.5%), and had at least one injury (53.3%). Participants consumed ≥2 fruits (68.9%) and ≥2 vegetables (83.6%) per day, daily breakfast (68.0%), ≤1 sugar-sweetened beverage (86.9%) and ≥7 cups of water (54.1%) per day, and ≤2 alcoholic beverages per week (59.8%). Participants reported ≥7 hours of sleep per night (65.5%), and no/little restless sleep (52.4%). Just under half of participants reported sitting ≥5 hours per day (46.7%). Exercise frequency at ≥3 days per week and ≥30 minutes per day was 95.9% and 98.4%, respectively, with jogging (68.0%) the most common mode. Well-being scores were high. Overall, Masters field hockey athletes are healthy and practice lifestyle behaviors conducive to positive health.

Ability for tennis specific variables and agility for determining the Universal Tennis Ranking (UTR): A Review and Recommendations

ABSTRACT

Our purpose was to investigate tennis specific measures to predict a player’s Universal Tennis Ranking (UTR) value and to see what percentage of the variables most influence the ranking. Methods: 15 male and 14 female athletes volunteered to participate in this study. Each volunteer performed no more than 16 total serves or eight from the add and deuce side down the “T”, no more than 16 total forehands and backhands down-the-line, three spider tests, and two trials of footwork taps in 30 seconds. Only the top two hits were analyzed. Results: A multiple linear regression was calculated predicting a player’s UTR based on serve, forehand, backhand, agility, and footwork taps. The regression equation was significant (F (5,23) = 29.66, p<.05) with an R squared value of 0.866. Coefficient of variation (CV) and intra-class correlation coefficients (ICC) were calculated to assess reliability between player serve (r=0.902), forehand (r=0.843) and backhand velocity (r=0.858), agility (r=-0.817), and footwork (r=0.472). More noticeable was the significant predictive value of serve (r=0.902) and backhand velocity (r=0.858) to the player’s UTR. Conclusion: These results underline the important relationship between the player’s UTR and tennis-specific characteristics (serve and backhand velocity) as assessed by the player’s stroke velocity. The ability of training regimens to improve tennis-specific metrics would improve performance qualities and the player’s UTR.
