Impact of curcumin supplementation on exercise performance and muscle damage after a soccer match: a double-blind placebo-controlled cross-over study.

Curcumin ingestion can mitigate muscle damage, soreness, and inflammation following a laboratory-based eccentric exercise. Similar effects were observed in recent field-based studies wherein responses were evaluated after a soccer match. However, various potential confounding factors, such as matching opponent skill levels and daily training conditions, may have influenced the outcomes. In the present study, we investigated whether curcumin intake ameliorates changes in muscle damage markers following a soccer match while controlling for the potential confounding factors. Fifteen collegiate athletes were tested in a randomized, double-blind, cross-over manner. They were recruited from the same college soccer team and thus followed the same daily training regimen and competition levels. Furthermore, athletes positioning during matches were counterbalanced. They consumed either 180mg/day of curcumin or a placebo starting 1h before the match and continuing for 2days after a match (two 45-min plays and a 15-min half-time). Muscle soreness, jump performance (including countermovement jump and rebound jump index), and inflammatory and muscle damage markers (high-sensitive C-reactive protein, serum creatine kinase activity, and urinary N-terminal fragment of titin concentration) were evaluated before and after the match. The washout period between matches was set at 1week. After the match, all markers showed similarity between the placebo and curcumin conditions (all P > 0.208). These findings indicate that ingesting 180mg/day of curcumin may not expedite recovery from muscle damage elicited by soccer matches in collegiate soccer players.

Attention Focus and its Relationship to some Basic Skills of the Diyala University Soccer Team Player for Futsal

The research aims to identify the relationship between attention focus and its relationship to some basic skills of the players of the Diyala University football team for futsal through attention focus as an indicator of the level of performance of basic skills. The researchers used the descriptive approach due to its suitability to the nature of this research. This research was conducted on a sample that was chosen by the intentional method and consisted of (20) players from the Diyala University futsal team, where the researchers used the attention focus test form (network test) to measure the quality of attention focus in the research sample. The researcher used the scoring and handling skills test, and after conducting the exploratory experiment on the university team players, who consisted of (5) players outside the research sample, and after processing the results, the research resulted in a positive correlation between the attention focus test and the handling and scoring skills. Attention focus (network test), using a training program to focus attention due to its great importance in some of the basic skills of futsal, conducted similar studies in games that require focus and accuracy to determine the players' ability.

Qualitative study of a Korean elite university soccer team from a vertical leadership and shared leadership perspective

ABSTRACT This study analyzes the leadership behaviours that have helped shape a successful university soccer team in Korea. More specifically, the research focuses on both vertical and shared leadership in a team. To gain an in-depth understanding of how the ‘Y team’ could have had so much continuous success over an eight-year period, this study uses a total of 16 semi-structured interviews with athletes and coaches. The study showed some first insights that the team can generate excellence even without top-ranked players when operating under a combined vertical and shared leadership approach. Useful implications for current and future soccer coaches exploring how to develop and implement various leadership behaviours were addressed.

The Effect of Transactional and Transformational Leadership Behaviours on Factors Establishing Teams’ Cultural Aspects to Promote Organizational Effectiveness

This study aimed to analyse the relationships between transactional leadership, transformational leadership, and organizational culture in university soccer teams. First, the study focused on the transactional and trans- formational leadership behaviours of soccer coaches in university soccer teams using Multifactor Leadership Questionnaire 5X (MLQ 5X) by Bass and Avolio (1990) as an instrument. Second, the cultural factors of the univer- sity soccer teams were measured using the Organizational Culture Assessment Questionnaire (OCAQ, Sashkin, 2001). Using random cluster sampling, 316 players in university soccer teams participated in the study. The study results showed that both transactional and transformational leadership had a positive effect on organizational team culture, but the effect of transactional leadership behaviour appeared more extensive than transforma- tional leadership behaviour did in the present study. In a Korean context, it remains undeniable that strong transactional leadership behaviours exist, and they exert significant influence on university soccer team culture, but the effect of transformation leadership behaviours was also obvious on team culture. It could be concluded that the combination of transactional and transformational leadership is likely to be a key factor in the successful development of organizational effectiveness.

Using the Session Rating of Perceived Exertion to Quantify Training Load in a Men's College Soccer Team.

Sams, ML, Wagle, JP, Sato, K, DeWeese, BH, Sayers, AL, and Stone, MH. Using the session rating of perceived exertion to quantify training load in a men's college soccer team. J Strength Cond Res 34(10): 2793-2799, 2020-The purpose of this study was to examine the training load (TL) programming of 3 training groups of a National Collegiate Athletic Association Division I men's college soccer team across a season. Thirty athletes were classified as starters (S), substitutes (NS), or redshirts (RS) based on the percentage of possible minutes played during the season. Training load was quantified at the season, phasic, and weekly levels by the session rating of perceived exertion. Between-group differences were observed at the season level (p < 0.001), and group-by-time interactions for average weekly TL were found at both the phasic (p = 0.04) and weekly levels (p < 0.001). In general, S accumulated greater TL than NS (effect size range for all analyses: -0.59 < d < 1.91) and RS (0.17 < d < 3.67), and NS accumulated greater TL than RS (-0.54 < d < 2.34). Within-group variation at the phasic level was less apparent (-0.35 < d < 1.44); however, all 3 groups displayed training variation at the weekly level (-1.80 < d < 3.24). The session rating of perceived exertion can serve as a low-cost, valid means of quantifying TL in men's college soccer athletes. Practitioners should be especially aware of the possibility of insufficient loading in NS.

Does the FIFA 11+ Program Prevent Hamstring Injuries in College-Aged Male Soccer Players? A Critically Appraised Topic.

Clinical Scenario: Hamstring injuries are the most prevalent lower-extremity injury among soccer players. The Fédération Internationale de Football Association (FIFA) has addressed this issue by developing the FIFA 11+ program, which is focused on improving strength and decreasing the incidence of lower-extremity injuries in the sport. This critically appraised topic focuses on this program as well as one of its components, the Nordic hamstring exercise, in the prevention of hamstring injuries. Clinical Question: Does the FIFA 11+ program prevent hamstring injuries in college-aged male soccer players? Summary of Key Findings: Four studies were selected to be critically appraised. The PEDro checklist was used to score the articles on methodology and consistency. All 4 articles demonstrated support for the clinical question. Clinical Bottom Line: There is moderate evidence to support the use of the FIFA 11+ program and Nordic hamstring exercise as part of a college soccer team's warm-up routine. Strength of Recommendation: Grade B evidence exists in support of incorporating the FIFA 11+ program to reduce the incidence of hamstring injuries in male college soccer players.

THE EFFECTS OF THE RESISTANCE TRAINING ON SERUM CORTISOL, IL-6, IL-8, AND TNF- α

Objective: The purpose of this study is to investigate effects of resistance training on IL-6, IL-8, TNF-α, blood hematocrit and cortisol levels. &#x0D; Materials and Methods: Thirteen players from Manisa Celal Bayar University soccer team and 14 sedentary male students were used as the study subjects. The subjects, whose average age was 18-24 years old, were healthy and free of any cardiovascular diseases. Anthropometrics measurements and blood samples were obtained from all the subjects. Blood samples were obtained basal sample (before the exercise), immediately after the training program (post-exercise), and 2 hours after the training program (2h post-exercise). All subjects participated in the training program in which intensity prescribed individually in 10 different exercises; seated leg press, knee extension, knee flexion, chest press, chest flys, lat pull down, shoulder press, triceps extension, biceps curl and sit-ups. Three sets of intensity of the each exercise were arranged according to pyramidal system at 70-80 % of the each participant. The volume of resistance training was 50-60 minutes. &#x0D; Results: Post exercise IL-6 (p= 0,05) and IL-8 (p= 0,04) concentration of athletes were statistically lower compared to that of sedentary group. Furthermore, serum cortisol concentrations were found to be decreased in both study groups in post exercise and 2h post exercise samples compared to basal values (p&lt;0,05). Post exercise IL-8 (p=0,04) and TNF-α (p=0,04) values of sedentary group increased significantly compared to values at 2h post exercise.&#x0D; Conclusion: IL-6, IL-8, and TNF-α responses to resistance training vary depending on the recruitment of different muscle fiber types by the trained individuals during the resistance training and the recovery of glycogen storage, which is found to be different from that of sedentary individuals.

Effect of Changes in Artificial Turf on Sports Injuries in Male University Soccer Players.

Background:Studies comparing the types and severity of trauma and injuries caused by different types of field surfaces have been conducted. However, there have been no studies on sports injuries caused by temporal deterioration of long-pile artificial turf fields and related decreases in the rubber chip and silica sand infill.Purpose:To investigate the influence of an artificial turf field on sports injuries in a university soccer team.Study Design:Descriptive epidemiological study.Methods:A total of 397 male soccer players who were members of a single university soccer team were surveyed over a 12-year period, from April 2003 to March 2015. During this period, the team played for 4 years on a soil field (2003-2006) and 8 years on artificial turf (2007-2014). We analyzed the effect of changes in the artificial turf on the incidence rate of sports injuries (injury rate per 1000 athlete-exposures). We calculated the incidence rate of injuries sustained by the team and compared the results for each year of the study.Results:After conversion of the field to artificial turf, there was a significant increase in the incidence of upper extremity trauma (P < .05). There was a significant increase in lower extremity sprains from 2007 to 2008, 1 year after the conversion from soil to artificial turf (P < .05). Analysis of the incidence of lower extremity muscle strain indicated that although the injury rate increased progressively, it decreased significantly after the insertion of additional rubber chips in 2014 (P < .05).Conclusion:After conversion to artificial turf, there was a significant increase in the incidence of upper extremity trauma. After the refurbishing with additional rubber chips, the incidence of lower extremity muscle strain significantly declined. When analyzing measures that could prevent sports injuries related to soccer, it is necessary to take into consideration the changes that occur to the artificial turf over time.

Pathogenesis of Fifth Metatarsal Stress Fractures in College Soccer Players

Category: Sports Introduction/Purpose: The pathogenesis of fifth metatarsal stress fractures remains uncertain. We hypothesized that physical characteristics and environmental factors, which have received limited attention in the literature thus far, might be involved in the development of such fractures. To test our hypothesis, we performed a medical checkup and a survey of the living environment of athletes in college soccer teams, and subsequently, we investigated the existence of fifth metatarsal stress fractures, and examined the differences between the injury group and the non-injury group. Methods: The survey and measurements were conducted in 273 male athletes from the same college soccer team between 2005 and 2013. A medical checkup, comprising assessment of stature, body weight, body mass index, arch height ratio, toe-grip strength, quadriceps angle, leg-heel angle, functional reach test, one-leg standing time with eyes closed, straight leg raise test, finger-floor distance, heel-to-buttock distance, ankle joint range of motion, and general joint laxity test, and a questionnaire survey were performed once a year. A survey was conducted at the time of injury that resulted in fifth metatarsal stress fractures. The study participants were separated into an injury group and a non-injury group, depending on whether they had a fifth metatarsal stress fracture. The measurement items and survey items were compared, and the association between the presence or absence of injury and the measurement items was analyzed. Results: Toe-grip strength was significantly weaker in the injury group, compared with the non-injury group, suggesting that a weak toe-grip is associated with fifth metatarsal stress fracture (p &lt; 0.05). In addition, injury on the non-dominant leg was more frequent in the fifth metatarsal stress fracture injury group (p &lt; 0.05). Between-group comparisons of the other items showed no statistically significant differences. Conclusion: The association between weak toe-grip strength and fifth metatarsal fracture suggests that a weak toe-grip may lead to an increase in the load applied onto the lateral side of the foot; this may cause mechanical stress on the bone. In addition, the effect of the non-dominant leg on the fifth metatarsal bone may need to be studied further.

An Acute Effects of Applied Stretching in Soccer Game Break Time

Background/Objectives: The purpose of this study was to investigate the effect of the static and dynamic stretching on agility and balance during break time of soccer game. Methods/Statistical Analysis: This study was performed for 25 among healthy university soccer team students. All data were analyzed using the statistical software SPSS ver. 23.0. The data were expressed as the mean ± standard deviation of the mean (SDM). For the comparison among the groups, two-way ANOVA and paired t-test was performed for the difference within a group. Significance was set as α .05) in the group to which the static type of stretching was applied and it was - .442sec (p .05).

Sex differences in jaw muscle duty factors during exercise in two environments: A pilot study

It is unknown if females and males use jaw muscles similarly during exercise. This pilot study assessed jaw elevator muscle duty factors (DFs=time of muscle activity/total recording time) at repeated sessions to test if DFs are reliable and different between sexes during exercises in two environments. Ten female and seven male subjects recruited from university soccer teams provided informed consent. Surface electromyography was recorded from masseter and temporalis muscles during biting and leg-extension laboratory exercises. Average activities to produce 20N bite-forces for each muscle and subject determined thresholds (5–80%·T20N) for subject-specific DF calculations during exercises performed in laboratory and natural environments. Subjects self-recorded via portable electromyography equipment during in-field leg-extension and weight-lifting exercises. Effects of variables on DFs were assessed via ANOVA (α=0.05) and simple effects testing (Bonferroni-adjusted p⩽0.012). All subjects used jaw muscles during exercises in both environments. DFs between laboratory sessions were reliable (R=0.84). During laboratory exercises, male temporalis DFs were significantly higher than female DFs from both muscles (p⩽0.001). During in-field exercises females had higher DFs during weight-lifting while males had higher DFs during leg-extensions. In-field sex differences were significant at most thresholds and showed larger effect sizes for leg-extension compared to weight-lifting exercises.

Balance Assessment Changes in Female Collegiate Soccer Players over a 2-Year Period

Objective: The purpose of this study was to measure the balance changes in female collegiate soccer players over a 2-year period. Methods: Seven females from a Division I university soccer team (starting mean age, 17.71 years; SD=0.49) completed the 2-year study. Subjects were assessed on the NeuroCom Smart® Balance Master system before their freshman seasons and were re-tested at the beginning of each subsequent fall season for static balance on the Sensory Organization Test (SOT) and for dynamic balance on the Limits of Stability (LOS) Test. Mean differences were analyzed with repeated measures ANOVA. Results: Players’ overall static balance improved as noted by the increase in the composite equilibrium score for the SOT: F2,12=12.94, p=0.001. Pairwise comparisons revealed a significant increase from year 1 [79.1 (2.9)] to year 2 [84.7(3.1)] (p=0.009) and year 1 to year 3 [86.4 (2.8)] (p=0.008). Significant improvements in balance were noted for the following SOT conditions: condition4 (F2,12=3.94, p=0.048); condition 5 (F2,12=13.77, p=0.001); and condition 6 (F2,12=4.44,p=0.036). Pairwise comparisons revealed changes from year 1 [85.8 (5.4)] to year 3 [91.6 (1.6)] for condition 4 (p =0.05) and year 1 [69.2 (6.4)] to year 3 [79.9 (6.0)] for condition 6 (p=0.036). In condition 5, balance improved from year 1 [59.5 (8.9)] to year 2 [76.5 (6.4)] (p=0.006) and from year 1 to year 3 [76.4 (7.1)] (p=0.008). A significant change was observed in LOS for Backward Endpoint Excursion (F2,12=5.44, p=0.021) with pairwise comparisons revealing a significant increase from year 1 [51.0 (11.2)] to year 3 [66.5 (10.2)] (p=0.017). Conclusion: This study showed that female soccer players’ performance increased components of static and dynamic balance,which indicates that participating in soccer may not be detrimental to the overall balance performance of a female collegiate soccer player and may actually enhance it.
