Background: There is limited research regarding the impact of workload on injury risk specific to women’s soccer. Wearable global positioning system (GPS) units can track workload metrics such as total distance traveled and player load during games and training sessions. These metrics can be useful in predicting injury risk. Purpose: To examine the relationship between injury risk and player workload as collected from wearable GPS units in National Collegiate Athletic Association (NCAA) Division I women’s soccer players. Study Design: Case-control study; Level of evidence, 3. Methods: Lower extremity injury incidence and GPS workload data (player load, total distance, and high-speed distance) for 65 NCAA Division I women’s soccer players were collected over 3 seasons. Accumulated 1-, 2-, 3-, and 4-week loads and acute-to-chronic workload ratios (ACWR) were classified into discrete ranges by z-scores. ACWR was calculated using rolling averages and exponentially weighted moving averages (EWMA) models. Binary logistic regression models were used to compare the 7:28 rolling average and EWMA ACWRs between injured and noninjured players for all GPS/accelerometer variables. The prior 1-, 2-, 3-, and 4-week accumulated loads for all GPS/accelerometer variables were compared between the injured and uninjured cohorts using 2-sample t tests. Results: There were a total of 53 lower extremity injuries that resulted in lost time recorded (5.76/1000 hours “on-legs” exposure time; 34 noncontact and 19 contact injuries). The prior 2-week (7242 vs 6613 m/s2; P = .02), 3-week (10,533 vs 9718 m/s2; P = .02), and 4-week (13,819 vs 12,892 m/s2; P = .04) accumulated player loads and 2-week (62.40 vs 57.25 km; P = .04), 3-week (90.97 vs 84.10 km; P = .03), and 4-week (119.31 vs 111.38 km; P = .05) accumulated total distances were significantly higher for injured players compared with noninjured players during the same time frames. There were no significant differences in player load, total distance, or high-speed distance ACWR between injured and noninjured players for both the rolling averages and EWMA calculations. Conclusion: Higher accumulated player load and total distance, but not ACWR, were associated with injury in women’s soccer players.

Context: A number of comprehensive injury-prevention programs have demonstrated injury risk-reduction effects but have had limited adoption across athletic settings. This may be due to program noncompliance, minimal exercise supervision, lack of exercise progression, and sport specificity. A soccer-specific program described as the F-MARC 11+ was developed by an expert group in association with the Federation Internationale de Football Association (FIFA) Medical Assessment and Research Centre (F-MARC) to require minimal equipment and implementation as part of regular soccer training. The F-MARC 11+ has been shown to reduce injury risk in youth female soccer players but has not been evaluated in an American male collegiate population. Objective: To investigate the effects of a soccer-specific warm-up program (F-MARC 11+) on lower extremity injury incidence in male collegiate soccer players. Design: Cohort study. Setting: One American collegiate soccer team followed for 2 seasons. Patients or Other Participants: Forty-one male collegiate athletes aged 18–25 years. Intervention(s): The F-MARC 11+ program is a comprehensive warm-up program targeting muscular strength, body kinesthetic awareness, and neuromuscular control during static and dynamic movements. Training sessions and program progression were monitored by a certified athletic trainer. Main Outcome Measure(s): Lower extremity injury risk and time lost to lower extremity injury. Results: The injury rate in the referent season was 8.1 injuries per 1000 exposures with 291 days lost and 2.2 injuries per 1000 exposures and 52 days lost in the intervention season. The intervention season had reductions in the relative risk (RR) of lower extremity injury of 72% (RR = 0.28, 95% confidence interval = 0.09, 0.85) and time lost to lower extremity injury (P < .01). Conclusions: This F-MARC 11+ program reduced overall risk and severity of lower extremity injury compared with controls in collegiate-aged male soccer athletes.

Abstract Context: Athlete monitoring using wearable technology is often incorporated with soccer athletes. While evaluations have tracked global outcomes across soccer seasons, there is little information on athlete loads during individual practice drills. Understanding these demands is important for athletic trainers for return-to-play decision-making. Objective: To provide descriptive information on total distance, total playerload (PL), distance per minute, and PL per minute for practice drill structures and game-play by player position among female soccer athletes across a competitive season. Design: Retrospective, observational field study. Setting: NCAA Division I university. Patients or other Participants: Thirty-two female college soccer players (20±1 years). Interventions: Athletes wore a single GPS and triaxial accelerometer unit during all practices and games in a single soccer season. Individual practice drills were labeled by the team's strength and conditioning coach, and binned into physical, technical and tactical skills, and small- and large-sided competition drill structures. Main Outcome Measures: Descriptive analyses were used to assess the median total distance, total PL, distance per minute, and PL per minute by drill structure and player position (defenders, midfielders, forwards/strikers) during practices and games. Results: Small- and large-sided competitive drills imposed the greatest percentage of workload across all measures for each position (~20% of total practice), followed by physical drills. When comparing technical and tactical, technical skills required athletes to cover the greatest distance (technical: ~17%; tactical: ~15%), tactical skills required higher play intensity during practices across all positions (technical: ~18%; tactical: ~13%). Defenders had the highest median PL outcomes of all positions during practices. Conclusions: Different practice drill types imposed varying levels of demands on female soccer athletes, which simulated game play. Athletic trainers and other clinicians may use this information for formulating objective return-to-play guidelines for injured collegiate women's soccer players.

Background: Early identification of the BMI and muscle weakness, can be promoted for developing future rehabilitation by giving proper training in athletes to reduce chance of injuries especially in female athletes. There-for the purpose of this study was to determine the correlation between BMI and hip muscle strength in young female athletes. Materials and Methods: study was conducted among college level female athletes from different colleges of Mangalore, Karnataka, India. 20 college level female athletes between 18-25 years with free from injury and involved at least 2 hrs. per week training session were included in this study. Athletes were excluded if participant had an acute injury during previous six months, had musculoskeletal surgery within the past year. Results: The total number of 20 young female athletes aged between 18- 25 were included in this study. Detailed results enumerated in detail in the results section. Discussion and Conclusion: There was no relationship between BMI and hip muscle strength. Identifying the relationship between BMI and hip muscle strength may help to prevent lower extremity injury risk in female athletes and specific muscle group training can be given as rehabilitation protocol. KEY WORDS: BMI, Hip Muscle Strength, Female Athletes, Lower Extremity Injury.

Purpose:During the competitive soccer season, women’s intercollegiate matches are typically played on Friday evenings and Sunday afternoons. The efficacy of a 42-h recovery period is not well understood. This investigation was conducted to determine performance differences between Friday and Sunday matches during a competitive season.Methods:Ten NCAA Division I female soccer players (20.5 ± 1.0 y, 166.6 ± 5.1 cm, 61.1 ± 5.8 kg) were monitored with 10-Hz GPS devices across 8 weekends with matches played on Friday evenings and Sunday afternoons. The players were outside backs, midfielders, and forwards. All players had to participate in a minimum of 45 min/match to be included in the study. Average minutes played, total distance covered, total distance of high-intensity running (HIR) (defined as running at a velocity equal to or exceeding 3.61 m/s for longer than 1 s), the number of HIR efforts, and the number of sprints were calculated for each match. Data for Friday vs Sunday matches were averaged and then compared using dependent t tests.Results:No differences were seen in minutes played, distance rate, or number of sprints between Friday and Sunday matches. A significant (P = .017) decrease in rate of HIR between Friday (25.37 ± 7.22 m/min) and Sunday matches (22.90 ± 5.70 m/min) was seen. In addition, there was a trend toward a difference (P = .073) in the number of efforts of HIR between Friday (138.41 ± 36.43) and Sunday (126.92 ± 31.31).Conclusions:NCAA Division I female soccer players cover less distance of HIR in games played less than 48 h after another game. This could be due to various factors such as dehydration, glycogen depletion, or muscle damage.

Athletes with a history of concussion (HC) are at an increased risk of sustaining lower extremity injuries. It is unclear if these individuals exhibit dynamic postural control deficits associated with lower extremity injury risk. The purpose of this study was to determine if collegiate athletes with a HC demonstrate differences in Y-Balance Test (YBT) performance compared to athletes with no history of concussion (NHC). A total of 116 varsity and club athletes from a Division-I university participated. Forty participants reported a HC (female/male: 31/9, age: 20.0 ± 1.4 years, height: 169.3 ± 13.1 cm, mass: 68.4 ± 14.0 kg) while 76 reported NHC (female/male: 60/16, age: 20.0 ± 1.7 years, height: 168.5 ± 12.9 cm, mass: 68.7 ± 14.6 kg). Individuals with a current concussion or lower extremity injury, or a history of lower extremity surgery were excluded. Participants completed the YBT anterior reach direction barefoot on both limbs. The YBT was completed by maximally reaching anteriorly, maintaining balance, and returning to the starting position without errors. Participants completed 4 practice trials and 3 test trials. Reach distances were averaged and normalized to leg length. Between-limb asymmetry was calculated as the absolute difference between the left and right limbs. Separate independent t-tests examined group differences in normalized reach distances and asymmetry. The proportion of participants in each group with >4 cm of asymmetry was compared using a χ2 test. Alpha was set at 0.05 for all analyses. No group differences were identified in normalized reach distances for the left (HC: 61.4% ± 9.2%, NHC: 60.8% ± 6.2%, p = 0.88, ES = 0.08) or right (HC: 61.4% ± 6.2%, NHC: 60.2% ± 6.8%, p = 0.51, ES = 0.17) limbs. However, a greater proportion of HC participants demonstrated >4 cm asymmetry (HC: 40.0%, NHC: 19.7%; p = 0.02) and these participants exhibited greater asymmetry (HC: 3.87 ± 3.69 cm, NHC: 2.40 ± 2.13 cm, p = 0.03; ES = 0.53). Athletes with a HC exhibited greater asymmetry compared to athletes with NHC. Anterior reach asymmetries of >4 cm are associated with greater lower extremity injury risk. The YBT may provide a clinical technique to further explore the relationship between concussion and lower extremity injury.
