This book was released on 2014 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Competition often requires teams that reside at sea level to compete against opponents whose residence is at a moderate altitude. This may pose a potential competitive disadvantage considering that moderate altitude may cause decrements in VO[subscript 2max], distance covered, and time to exhaustion in endurance athletes. The purpose of this study was to examine the effect of altitude on game performance measures. Six NCAA Division I female soccer players (20.33 ± 1.21 y; 168 ± 6.45 cm; 62.5 ± 6.03 kg) were retrospectively examined. Comparisons were made between two competitions that were played at sea level (SL) within two weeks of a game played at a moderate altitude (1840 m) on game characteristics including high intensity running (HIR) and total distance covered (TDC). Analysis was performed on these six players who met a threshold of playing sixty or more minutes in each competition. A 10-Hz global positioning system (GPS) was used to measure distance and velocity. The rate of TDC and HIR during the game (m·min−1) and percentage of time at HIR during competition were evaluated. The two games at SL were averaged to establish baseline performance and the mean results were compared with the single game played at altitude. Paired samples t-tests were performed to determine if any mean differences existed between performance at altitude and sea level. Significant differences (p [less than] 0.05) were seen in minutes played between the games at SL (74.23 ± 2.93 min) versus altitude (83.24 ± 5.27 min). The relative distance rate during the game at altitude was lower at altitude (105.77 ± 10.19 m·min−1) than at SL (120.55 ± 8.26 m·min−1). HIR rate was greater at SL (27.65 ± 9.25 m·min−1) compared to altitude (25.07 ± 7.66 m·min−1). The percent of time spent at high intensity was not significantly different (p = 0.064), yet tended to be greater at sea level (10.4 ± 3.3%) than when they performed at altitude (9.1 ±2.2%). Soccer performance at a moderate altitude appears to reduce the rate at which players run throughout the competition, as well as their rate at a high intensity. Results suggest that teams that reside at SL may be at a competitive disadvantage when competing at altitude.

Book excerpt: This collection investigates the time-motion characteristics of collegiate soccer games, repeated-sprint ability in female players, and skill-based assessments of collegiate male and female players. In females, research has shown few between-position differences in physiological characteristics. Additionally, female field players can display similar aerobic fitness to elite players as assessed by the Yo-Yo Intermittent Recovery Test Level 1. The authors suggest that collegiate female players may need further development in high-intensity running and repeated-sprint ability. Afterwards, they present research supporting the idea that that turfgrass maintenance on soccer fields in Slovenia differs significantly, and several managers lack knowledge about proper turfgrass management. However, the maintenance budget is not the most important factor in determining the appearance of the soccer fields. A subsequent review is presented with the goal of reviewing the trainability of short sprinting in youth soccer players. The authors examined studies from 2005 to the present which focused on improving sprint or agility performances, and included a description of the training protocol, pre-and post-test measures (mean and standard deviation) for the training group and the control group. The findings demonstrate progress in short straight-line sprinting and in agility performance with different training regimes. Another study is presented analysing the evolution of the physical condition in young elite soccer players during the full competitive period throughout eight seasons. In this study, one hundred and eleven young soccer players belonging to the reserve team of a Spanish professional soccer academy were examined. The last study describes the perceived exertion of soccer players in the pre-season and in-season periods and to analyses the differences in the perceived effort between friendly and official matches in relation to the minutes played in young soccer players.

This book was released on 2016 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: Author's abstract: The purpose of this study was to evaluate the effect of halftime sports drink ingestion on second half performance in U16 female soccer players using GPS technology. While 12 players initially took part in the study, only six players were included in the analysis (age, 15.97±0.45 years; height, 159.62±5.35cm; body mass, 54.87±4.25; body mass index, 21.58±2.10 kg·m-2). In a double-blinded study design, twelve U16 female soccer players were randomly assigned to two groups (carbohydrate- sports drink or placebo). During half time of each game, players were provided with 500 ml of a drink and consumed the same liquid at halftime during all games of the first weekend, with the opposite beverage consumed during friendly matches on a subsequent weekend. Absolute running distance, distance covered per minute, distance covered in each of six velocity categories, and game load were tracked using GPS/HR during 2 games on 2 consecutive weekends. Distance covered at walking speed was significantly higher for the sports drink group (F = 11.026; p= .007), specifically in the second half. Consequently, sports drink influenced distance covered at low-intensity running speed (F= 7.275; p= .021), while placebo group decreased distance covered in the second half comparing to first half, supplementation group increased from first to second half. There were no significant changes between groups for any other speed velocities variables. Despite the lack of significance found between groups, this study found a decrease in performance from first half to second half at fast running (F = 6.807; p= 0.024), and high intensity running speed (F = 19.648; p≤.001). No significant results were found at distance covered per minute. This study conclude that sports drink ingestion have no benefit in preventing deterioration in performance, and overall sports drink did not influence youth female soccer players performance throughout a weekend of games

Download or read book The Effects of Heading Motion and Gender on Lower Extremity Biomechanics in Soccer Players written by Abdulmajeed Barakat Alfayyadh and published by . This book was released on 2018 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soccer continues to experience growth internationally in both men and women. Thus, it's reasonable to predict a high rate of injuries amongst those athletes since soccer includes strong physical contact. ACL injury is one of the most common injuries among athletes, and (70-84%) of ACL injuries occurs in non-contact situations, which often are associated with landing, deceleration, and sudden change of movement direction, and these situations might end with knee valgus collapse which's a common mechanism of ACL injury. Further, there are biomechanical differences of lower extremity joints in various tasks with both genders, which apparently means that the task utilized plays a crucial influence on joints dynamics. In soccer, the heading motion is one of the most common activities, which is more likely associated with landing. The purpose of this study was to investigate the effect of forward heading motion by comparing the kinetics and kinematics of lower extremity between genders during 1) a stop-jump task and 2) a jump-heading task. 10 male and 10 female soccer players performed 5 stop-jumps and 5 jumps with heading a soccer ball. Findings displayed a combination of reduced initial knee flexion, greater initial hip flexion, greater peak vertical GRF, and greater peak knee extension moments with both genders during the jump-heading task. Additionally, greater peak knee abduction angles were observed among female players during both tasks. These findings suggest that a higher risk of non-contact ACL injuries might occur during the jump-heading task compared with the stop-jump task, and this risk could be higher among female players than male players. These findings might lead soccer trainers to consider different strategies and techniques of landing after heading motions in game-like conditions. Also, PTs and rehabilitation designers who work with ACL-injured patients might consider the outcome of this study. Future studies should consider to examine ankle dynamics in addition to knee and hip in game-like conditions.

This book was released on 2011 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The primary purpose of the investigation was to determine the most closely related assessment between the agility t-test, countermovement vertical jump, fly-in 40-yard dash, lower limb length, and percent body fat when correlated to kicking power as measured by the Tendo FitroDyne Powerlizer. The study also aimed to form a prediction model based on all of the independent variables that could be used to predict soccer-specific kicking power. The study included 21 female soccer players (19 + 0.92 years) from Saint Gregory's University (n=11) and Oklahoma City University (n=10). The best score from the Tendo, agility t-test, countermovement vertical jump, and fly-in 40-yard dash was recorded for each participant. The percentage of body fat was determined using skinfold calipers and limb length was measured on the dominant kicking leg. A Pearson's correlation coefficient was used to identify relationships between kicking power and each of the independent variables. A backward multiple regression was administered in order to determine the independent variables that were able to best predict kicking power. The results from the Pearson's indicated that a significant relationship exists between kicking power and percent body fat (r = 0.630, p = .001) and limb length (r = 0.418, p = .047) while no significant relationships exist between kicking power and each of the field assessments of lower limb power. The backward multiple regression results indicate that limb length and percent body fat are the best predictors of kicking power. The primary investigator concluded that although the correlations between kicking power and limb length and %BF were significant, the field assessments of lower limb power were not correlated to kicking power indicating that the Tendo may not have effectively measured the instep soccer kick."--Abstract.

This book was released on 2016 with total page 77 pages. Available in PDF, EPUB and Kindle. Book excerpt: Author's abstract: The purpose of this study was to evaluate the relationship between changes in running performance and the stress-recovery state in Division I collegiate soccer players. Methods: Running performance was evaluated in eight NCAA Division I male soccer players (179.39 ± 5.24 cm; 75.46 ± 5.98 kg; 20.37 ± 1.41 yrs.) over the course of 12 games during a single competitive season. The 12 games were divided into four blocks [B1(n=3), B2(n=3), B3(n=3), and B4(n=3)]. Running performance and game load were assessed using a wearable physiological harness and Global Positioning System (GPS) module. Game load, absolute distance, and distance covered while engaging in walking (0.2-2.0 m·s-1; 0.72-7.20 km·h-1), jogging (2.01-3.70 m·s-1; 7.21-13.32 km·h-1), low speed running (3.71-4.99 m·s-1; 13.33-17.99 km·h-1), high speed running (5.0-6.0 m·s-1; 18.0-21.60 km·h-1) sprinting (6.01+ m·s-1; 21.61+ km·h-1), low-intensity running (LIR: 0.2-3.70 m·s-1; 0.72-13.32 km·h-1) and high-intensity running (HIR: > 3.70 m·s-1; > 13.32 km·h-1) were assessed during each block. These variables were also assessed relative to minutes played. Stress-recovery state was assessed using the RESTQ 52 Sport, which was administered to each athlete twice during each block, separated by at least one week. Measures of general stress (GS), general recovery (GR), sport specific stress (SSS), sport specific recovery (SSR), global stress (GLS), global recovery (GLR) and the recovery-stress balance (RSB). Results: Total distance was significantly greater during B4 compared to B1 (p=0.027). Absolute jogging distance and low-speed running distance were significantly greater during B4 compared to all other time points (p's ≤ 0.05). Absolute LIR distance was significantly greater during B4 compared to B1 (p=0.034). Jogrel was significantly greater during B4 compared to B1 (p=0.001) and B3 (p=0.001). Analysis of correlation coefficients between running performance and RESTQ scales indicate that greater high-speed/HIR is associated with increased stress. Similarly, greater low-speed/LIR is associated with greater recovery. However, changes in SSR did not correlate with changes in running performance from B1 to B4. Conclusions: The results of this study indicate that running performance declined across the season. However, changes in performance were not related to changes in SSR, as determined via the RESTQ 52 Sport questionnaire.

This book was released on 2017 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: The objectives of this study were to (i) describe soccer training (e.g., volume, types), anthropometry, body composition, and physical fitness and (ii) compute associations between soccer training data and relative changes of anthropometry, body composition, and physical fitness during a soccer season in female elite young athletes. Seasonal training (i.e., day-to-day training volume/types) as well as variations in anthropometry (e.g., body height/mass), body composition (e.g., lean body/fat mass), and physical fitness (e.g., muscle strength/power, speed, balance) were collected from 17 female elite young soccer players (15.3 ± 0.5 years) over the training periods (i.e., preparation, competition, transition) of a soccer season that resulted in the German championship title in under-17 female soccer. Training volume/types, anthropometrics, body composition, and physical fitness significantly varied over a soccer season. During the two preparation periods, higher volumes in resistance and endurance training were performed (2.00 ≤ d ≤ 18.15; p
