Fatigue Induced by Repeated Changes of Direction in Élite Female Football (Soccer) Players: Impact on Lower Limb Biomechanics and Implications for ACL Injury Prevention.

BackgroundThe etiology of Anterior Cruciate Ligament (ACL) injury in women football results from the interaction of several extrinsic and intrinsic risk factors. Extrinsic factors change dynamically, also due to fatigue. However, existing biomechanical findings concerning the impact of fatigue on the risk of ACL injuries remains inconsistent. We hypothesized that fatigue induced by acute workload in short and intense game periods, might in either of two ways: by pushing lower limbs mechanics toward a pattern close to injury mechanism, or alternatively by inducing opposed protective compensatory adjustments.AimIn this study, we aimed at assessing the extent to which fatigue impact on joints kinematics and kinetics while performing repeated changes of direction (CoDs) in the light of the ACL risk factors.MethodsThis was an observational, cross-sectional associative study. Twenty female players (age: 20–31 years, 1st–2nd Italian division) performed a continuous shuttle run test (5-m) involving repeated 180°-CoDs until exhaustion. During the whole test, 3D kinematics and ground reaction forces were used to compute lower limb joints angles and internal moments. Measures of exercise internal load were: peak post-exercise blood lactate concentration, heart rate (HR) and perceived exertion. Continuous linear correlations between kinematics/kinetics waveforms (during the ground contact phase of the pivoting limb) and the number of consecutive CoD were computed during the exercise using a Statistical Parametric Mapping (SPM) approach.ResultsThe test lasted 153 ± 72 s, with a rate of 14 ± 2 CoDs/min. Participants reached 95% of maximum HR and a peak lactate concentration of 11.2 ± 2.8 mmol/L. Exercise duration was inversely related to lactate concentration (r = −0.517, p < 0.01), while neither%HRmax nor [La–]b nor RPE were correlated with test duration before exhaustion (p > 0.05). Alterations in lower limb kinematics were found in 100%, and in lower limb kinetics in 85% of the players. The most common kinematic pattern was a concurrent progressive reduction in hip and knee flexion angle at initial contact (10 players); 5 of them also showed a significantly more adducted hip. Knee extension moment decreased in 8, knee valgus moment increased in 5 players. A subset of participants showed a drift of pivoting limb kinematics that matches the known ACL injury mechanism; other players displayed less definite or even opposed behaviors.DiscussionPlayers exhibited different strategies to cope with repeated CoDs, ranging from protective to potentially dangerous behaviors. While the latter was not a univocal effect, it reinforces the importance of individual biomechanical assessment when coping with fatigue.

The Roles of Guardians Deities of Book of Cavern from Scenes Texts of King Ramses Iv Tomb

This papers aims to focus the light on the role of the guardians deities of the book of the Cavern from the scenes and texts of the Tomb of King Ramses IV and their benefits for the soul of the King, The 1st and the 2nd division of the book of Cavern included the figure of the guardian deities, was depicted completely on the 3rd corridor {C} of the tomb Meanwhile the figures of the guardians deities from the 3rd to the 11th Cave were represented only in figures and its explaining texts explain their protective role for the soul of the deceased. (Piankoff,1941,1942,1943) in his Articles (Le livre des Querets) highlighted the description of the journey of the Sun god and the soul of the deceased accompanied him through the Cavern of the Underworld.(Hart,1986) mentioned only the names and epithets of these guardian deities ,So the researcher will highlight Why these guardian Deities was represented only in figures and mentioned in texts explaining their protective roles for the soul of the King in the Caves of the underworld ? instead of the depiction From the 3rd to 6th division of the book of the Cavern to inform the soul of the King about the role of these guardians deities of each Cave during his journey accompanied the Sun god through the Cavern of the Underworld.

Glissonean approach for hepatic inflow control in minimally invasive anatomic liver resection: A systematic review.

The Glissonean approach has been widely validated for both open and minimally invasive anatomic liver resection (MIALR). However, the possible advantages compared to the conventional hilar approach are still under debate. The aim of this systematic review was to evaluate the application of the Glissonean approach in MIALR. A systematic review of the literature was conducted on PubMed and Ichushi databases. Articles written in English or Japanese were included. From 2,390 English manuscripts evaluated by title and abstract, 43 were included. Additionally, 23 out of 463 Japanese manuscripts were selected. Duplicates were removed, including the most recent manuscript. The Glissonean approach is reported for both major and minor MIALR. The 1st, 2nd and 3rd order divisions of both right and left portal pedicles can be reached following defined anatomical landmarks. Compared to the conventional hilar approach, the Glissonean approach is associated with shorter operative time, lower blood loss, and better peri-operative outcomes. Glissonean approach is safe and feasible for MIALR with several reported advantages compared to the conventional hilar approach. Clear knowledge of Laennec's capsule anatomy is necessary and serves as a guide for the dissection. However, the best surgical approach to be performed depends on surgeon experience and patients' characteristics. Standardization of the Glissonean approach for MIALR is important.

Determinants of Dribbling and Passing Skills in Competitive Games of Women's Basketball.

This work aimed to identify the influence of selected endogenous (internal load) and exogenous (possession duration, game quarter, and defensive pressure) factors in natural game conditions on the efficiency of dribbling and passing skills. Dribbling and passing skills were assessed during four games of U19 female basketball players and five games of senior (2nd division) female basketball players. In total, 551 dribbling and 914 passing executions were evaluated. Binary logistic regression identified defensive pressure of the opponent as a predictor of dribbling and passing skills effectivity. When the defensive pressure of the opponent was medium, the chances for the ineffective pass were 1.997 times more likely (95% CI; 1.179–3.383), as it is at the minimum defensive pressure. When the defensive pressure of the opponent was high, the chances for ineffective dribbling were 7.45 times more likely (95% CI; 3.672–15.113) and for ineffective pass were 8.419 times more likely (95% CI; 4.6–15.409), as it is at minimum defensive pressure. The game quarter and the internal load were not identified as the predictors influencing the dribbling and passing effectivity. Possession duration was also an insignificant predictor of dribbling and passing skills effectivity. However, the passing skill effectivity decreases when the shot clock is winding down. These findings confirm the importance of transferring game situations into the training process. Coaches should take into account these factors when they want to stimulate determinants of player performance in a balanced and systematic way.

‘I do feel good because my stomach is full of good hotcakes’: Comfort Food, Home and the USAAF in East Anglia during the Second World War

AbstractThis article analyses the important role that food played in providing ‘comfort’ to the service personnel of the United States Army Air Force (USAAF) serving in East Anglia during the Second World War. Current theories on comfort food will be discussed before an examination of letters, diaries, and memoirs held by the 2nd Air Division Memorial Library (2ADML), Norwich, UK. It is clear that food played an important role in maintaining morale. Certain foods had the ability to evoke nostalgic thoughts of home. Not only did the food provide solace, it also reminded the troops of what they were fighting for. This article also demonstrates that USAAF personnel in East Anglia had a wide selection of foods from which they could gain comfort.

Оцінка стану сперматогенезу щурів за умов моделювання радіаційного ураження та впливу препаратів природного походження

Male infertility is probably to be affected by intense heat exposure and extreme exposure to pesticides, irradiation, electromagnetic radiation and other hazardous substances. The authors of most of the works agree that the cells of the basement membrane of the tubules and spermatogonia, which are quickly exhausted after irradiation, are the most vulnerable in the testes. The type and extent of these changes depends on the dose, duration and frequency of radiation. The participation of connective tissue in almost all typical pathological conditions has been shown: inflammation, allergy, carcinogenesis, hypoxia, free radical oxidation processes, etc. The purpose of the work was to study evaluation the state of rats' spermatogenesis under conditions of the total irradiation exposure and to correct the pathological process with drugs of natural origin Chondroitin sulfate and "Bioglobin-U". Material and methods. A model of total single irradiation with a dose of 3 Gy was used to obtain the pathology of the testes, after which the substance Chondroitin sulfate was administered at a dose of 60 mg / kg; comparison drug Tribestan at a dose of 60 mg/kg; the drug "Bioglobin-U" at a dose of 200 μl / kg and Chondroitin sulfate + Tribestan in the above doses. Results and discussion. 30 days of exposure of single total irradiation with a dose of 3 Gy led to significant disruption of the morphological state of the testes and spermatogenic epithelium of rats. Thus, in rats with irradiation, the number of normal spermatogonia in the convoluted tubules was reduced by 5.7 times, there were practically no convoluted tubules with spermatocytes in the metaphase of the 2nd maturation division (with the 12th stage of meiosis) and tubules with desquamated spermatogenic epithelium, the index of spermatogenesis decreased by almost 6.5 times. The introduction of natural origin drugs led to an improvement in the quantitative and qualitative indicators of spermatogenesis. Conclusion. In the conditions of irradiation exposure, Chondroitin sulfate has more significant regenerative properties, the effect of which is almost 1.9 times better than the effect of the reference drug Tribestan. The effectiveness of "Bioglobin-U" in these experimental conditions was somewhat inferior to Chondroitin sulfate, but this drug was almost 1.4 times more effective than the reference drug Tribestan. The combination of Tribestan and the substance Chondroitin sulfate was more than 1.4 times more effective than the reference drug Tribestan itself

Endurance Capacities in Professional Soccer Players: Are Performance Profiles Position Specific?

The aim of this study was to investigate position-specific endurance performance of soccer players. 136 professional players competing in the 1st and 2nd division in Germany were divided into the positional groups goalkeepers (GK), central defenders (CD), wingers (WI), central midfielders (CM), and forwards (FW). All players performed an incremental treadmill test with blood lactate sampling until exhaustion with the following endurance parameters being obtained: Fixed aerobic threshold (v2mmol/l), fixed anaerobic threshold (v4mmol/l), individual aerobic threshold (vLT), individual anaerobic threshold (vIAT), and maximum velocity (vmax). Results revealed significant differences between GK and all outfield playing positions for all endurance parameters (p ≤ 0.03; ES 0.87–2.19). No significant differences among outfield playing positions were evident for any of the parameters. However, trends were found in favor of the CM compared to the WI (p = 0.11; ES = 0.68) and the FW (p = 0.06; ES = 0.47) relating to vLT as well as in favor of the CM compared to the WI (p = 0.10; ES = 0.56) relating to vIAT. Findings suggest that goalkeepers possess the lowest endurance capacity compared to other playing positions. While outfield players in general showed similar endurance performance, CM seem to possess the highest aerobic capacity of all positions as indicated by all lactate-based thresholds, however, with only small to moderate ES. These findings could lead one to question the appropriateness of current endurance training regimes to prepare all players adequately for their positional match-running demands. Indeed, endurance training of players should be specific to their match-running demands. However, it remains unknown to what extent these demands are position or player specific.

Assessing the Anthropometric Profile of Spanish Elite Reserve Soccer Players by Playing Position over a Decade.

The aims of this study were to describe the evolution of the anthropometric profile of soccer players over a decade and to compare the anthropometric profiles of players promoted from an elite reserve team to high-level soccer with those players who were not promoted. We examined the body mass, height, body-mass index, and body fat of 98 players enrolled in the reserve team from 2008 to 2018. The players were classified in terms of (a) the highest competitive level they achieved up to the 2019/2020 season (i.e., Spanish 1st–2nd divisions or semi-professional); (b) the period in which they played their last season on the team; and (c) their playing position. Over time, the height of goalkeepers, lateral midfielders, and attackers has increased (effect size = 0.66 ± 1.13) but has decreased in central midfielders (effect size = 0.83). The body fat of defenders has also fallen (effect size = 0.55 ± 0.95). Spanish high-level goalkeepers, lateral midfielders, and attackers were taller than their semi-professional player counterparts (effect size = 1.20 ± 1.98). Body fat did not determine promotion from a reserve team to high-level soccer, but height may be an advantage for several playing positions. The assessment of the anthropometric profile and the application of interventions should be designed according to the playing position.

Dietary Intake and Body Composition Characteristics of National Football League Players

Background: It has been well documented that adequate body composition characteristics and good nutrition practices play significant roles in maintaining good health, proper immune functioning, muscle growth and repair, and delaying fatigue in continuously intense athletic performance. It would be incumbent, however, to support imported information with local data to enhance effective implementation. Objectives: To examine dietary intake and body composition characteristics of National Football League Players in the Ashanti region of Ghana. Methods: Cross-sectional study was used. 95 football players from the premier, 1st and 2nd divisions of the Ghana National Football League were recruited. A 24-hour dietary recall was used to assess the dietary intake of the players. Body composition characteristics of body mass index, percentage (%) body fat, visceral fat and percentage (%) muscle mass were measured. Results: There were 8 (9.3%) goalkeepers, 29 (33.7%) defenders, 34 (39.5%) midfielders and 15 (17.4%) strikers. 42 (44.2%) of the players ate twice per day. Players within age group of 20 - 25 (49, 51.6%) had the highest mean total energy intake (2342.96 ± 848.18), carbohydrates (324.18 ± 106.35), proteins (75.54 ± 23.94) and fats (83.00 ± 50.76). Midfield players had the highest mean total energy intake (2216.26 ± 803.87), carbohydrates (315.74 ± 121.02), proteins (74.23 ± 26.35) and fats (71.59 ± 34.32). 82 (86.3%) had normal weight, 79 (83.2%) normal % body fat, 45 (47.4%) had very high % muscle mass. Conclusions: The sample in this study has low total energy intake compared to other studies. Insufficient nutritional diets could suggest the reason for the low energy intake. If low energy intake persists, the players might be at high risk of chronic cardiovascular diseases and diabetes conditions.

The Relation between Scenes and Texts of the Book of the Gates and Amduat applied on Seti I Tomb

This paper investigated the relation between the Book of Gates and the Book of Amduat applied on the tomb of king Seti I (KV17) According to Piankoff (1962) statement that the scenes of the first 5 divisions of the Book of Gates related to the first 6 hours of the Book of Amduat, Regen, (2014) highlighted the relation between scenes of the 1st and 2nd of the version without illustration of the book of Amduat and the 1st and the 2nd division of the book of Gates on the tomb of (Pedeamenope TT33).

Spanish Elite Soccer Reserve Team Configuration and the Impact of Physical Fitness Performance

The aim of this study was threefold: 1) to assess the configuration of an elite reserve soccer team, 2) to compare physical fitness performance of promoted and new players according to the playing position, and 3) to analyze the level of competitive participation attained by these players. We considered physical fitness tests (5 m and 15 m sprint, countermovement jump [CMJ] and aerobic endurance) performed by 192 players (age = 20.2 ± 2.3 years) enrolled in the reserve team of a Spanish La Liga club from 1994 to 2013. The players were classified according to the previous club criterion (promoted from the soccer academy and new players signed from other clubs), b) their playing position, and c) the competitive level attained until the 2016/2017 season (Spanish 1st and 2nd Divisions and the remaining competition levels). The proportion of promoted and new players was similar (p = 0.47). Overall, no substantial differences (unclear-small) were found in physical fitness performance between promoted and new players. Considering the playing position, promoted lateral defenders (LDs) showed better sprinting (ES = moderate) and CMJ (ES = moderate) performance than new LDs. In addition, promoted central midfielders (CMs) demonstrated better performance in the 5 m sprint and the CMJ (ES = moderate) than new CMs. The percentage of players who later competed in the Spanish 1st and 2nd Divisions was greater in promoted players compared to new players (p = 0.006). Physical fitness performance did not determine the selection of new players in a soccer elite reserve team. We may conclude that soccer academies should prioritize the selection and the training process of youth soccer players.

Comparison of Morphological Profiles and Performance Variables between Female Volleyball Players of the First and Second Division in Portugal.

Knowledge of players’ anthropometric profiles may contribute to a better understanding of the differences between their performance levels. For example, vertical jump height, which is a major indicator of a volleyball player’s performance, is influenced by favorable anthropometric variables. This study’s aim was to describe anthropometric profiles of elite female volleyball players competing in the 1st and 2nd divisions in Portugal and to link these profiles with performance skills such as jump height obtained during blocking and spiking actions. Fifty-nine volleyball players were analyzed according to their competitive level, forming three independent groups: GA (n = 20, A1 division, ranked first), GB (n = 21, A1 division, ranked last) and GC (n = 18, A2 division). Anthropometric data collected included body mass and height, arm span, seven skinfolds (triceps, biceps, subscapular, suprailiac, abdominal, thigh and calf), four body perimeters (relaxed brachial, contracted brachial, thigh and calf), and two body diameters (humeral and femoral). Performance data included the height obtained during block and spike actions. Significant differences were found between groups (GA/GB from A1 and GC from A2). Players in the GA had the highest body mass (68.05 ± 6.62 kg, p < 0.05), body height (176.35 ± 6.21 cm, p < 0.05), arm span (177.59 ± 6.09 cm, p < 0.05), lean mass (53.51 ± 4.94 kg, p < 0.05) and vertical jump heights (block: 0.36 ± 0.06 m and spike: 0.43 ± 0.05 m, p < 0.05). As expected, the fat mass percentage of GA players was the lowest (21.30 ± 2.61%). The results suggest that anthropometric profiles of volleyball players may vary according to the competitive level. The higher body mass, body height, arm span, and lean mass presented by GA players in comparison with GC players suggest these variables are important for top-level performance, since these athletes also exhibited higher jump heights. Variables such as height and arm span have a considerable genetic influence and could be important for early talent identification in volleyball. Other variables such as body mass, lean mass and vertical jump performance are more complex, since they also reflect the effects of environmental and training conditions.

When tongue strength exercises reflect in the cervical region.

To compare the impact of isokinetic exercise (tongue suction on the palate) in the cervical region of Class I and Class II / 2nd Division participants, considering the average and the symmetry of Root Means Square (RMS) of suprahyoid and suboccipital muscles and cervical sensory reports. 11 participants Class I and 19 Class II / 2nd Division, both genders, mean age 33.4 ± 14.1 years. For the analysis of RMS average and symmetry, electromyography was performed in the suboccipital and suprahyoid muscles, bilaterally, at rest and suction of water in the initial, intermediate and final phases. The cervical sensation was evaluated qualitatively during the exercises. the mean RMS did not differ between Classes (p=0.7), but showed an increase in the intermediate phase in the suboccipital musculature (p=0.0001) and decrease in the suprahyoid musculature. In symmetry, the suprahyoid musculature showed a significant difference between classes (p=0.0001) during the intermediate phase. In the Class I participant the symmetry was reestablished in the final phase, a fact that did not occur in Class II / 2nd Division. Regarding the cervical sensation, only the Class II / 2nd Division had expressive complaints. The Isokinetic suctioning exercise of the tongue against the palate, had an expressive repercussion with reports of discomfort and neck pain in the Class II / 2nd Division participants. On average RMS, there was no difference between the classes, but in the intermediate phase, the suboccipital muscles showed a significant increase in the activity. Symmetry in the suprahyoid musculature had a significant difference between the classes and asymmetry in the intermediate phase.

3 Żelazna Dywizja Strzelecka Armii Ukraińskiej Republiki Ludowej w 1920 r. Zarys szlaku bojowego w wojnie polsko-bolszewickiej

The subject of the article is the battle route of the 3rd Iron Rifle Division of the Ukrainian People’s Republic Army in the last year of the Polish-Soviet war. This formation was the strongest and most numerous in the Ukrainian armed forces in 1920. It was commanded by Oleksandr Udovychenko, a famous and very talented officer. It should be noted that the 3rd Iron Rifle Division was initially formed at the Polish Army as the 2nd Rifle Division, but due to the presence of many veterans of the 3rd Iron Division of 1919 in its ranks, which was also commanded by Udovychenko, it was decided to rename the formation. The 3rd Iron Rifle Division took an active part in the Kiev expedition in the spring of 1920. It fought on the southern section of the front in the Mohyliv-Podilskyi area. Later, in the summer of 1920, it took part in the defense of Eastern Galicia against the Red Army. It succeeded in several fights against the Bolsheviks there, among others at Sydoriv and Horodenka. Then it participated in further combat activities in Podolia. After 18 October 1920, the Ukrainian People’s Republic Army had to continue fighting on its own due to the signing of a ceasefire between Poland and Soviet Russia. The warfare conducted until the second half of November 1920 ended in defeat for the Ukrainians, whose armed forces withdrew to the Polish territory, where they were interned. In this group there were also soldiers of the 3rd Iron Rifle Division.

Analysis of parents’ behaviour in grassroots football from a systematic observation

A significant number of investigations highlight that parents possess a great potential to influence positively or negatively the sport experience of their children. It is necessary to emphasize that they can also perform an astonishing number of inappropriate behaviours during the course of their sons’ sport events. In this investigation, the management, pressure, comprehension and active participation comments performed by parents in grassroots football matches have been analysed through the systematic observation. Twelve teams have been observed which belong to the 2nd division league of U-15 in the Balearic Islands (Spain) during 2016-17 season through 12 recordings. These comments were coded by trained observers using LINCE® recording software and POISE (Parents’ Observation Instrument at Sport Events) (Kidman and McKenzie, 1996). The results show that neutral comments are the most notorious followed by positives and negatives. In conclusion, it must be mentioned that the relevance of this study is double: (1) It provides objective data about comments done by parents-spectators during the matches of their children; (2) it adds necessary information to carry out a systematic observation of parents and spectators in grassroots sport from the grandstands.

Midfield players had the highest mean total energy intake (2216.26 ± 803.87), carbohydrates (315.74 ± 121.02), proteins (74.23 ± 26.35) and fats (71.59 ± 34.32). 82 (86.3%) had normal weight, 79 (83.2%) normal % body fat, 45 (47.4%) had very high % muscle mass. Conclusions: The sample in this study has low total energy intake compared to other studies. Insufficient nutritional diets could suggest the reason for the low energy intake. If low energy intake persists, the players might be at high risk of chronic cardiovascular diseases and diabetes conditions.

Body Composition and Somatotype in Elite Handball Players

As the main objective, this research work had to compare pre and post complex training effects on body composition in elite handball players in the Spanish 2nd Division. Eleven players were included in the study. Six of them formed an experimental group, and 5 of them the control group. They have undergone the complex training session which was done once a week. The following parameters were analyzed: BMI (Body Mass Index), somatotype, FM (Fat Mass), MM (Muscle mass), RM (Residual Mass), WHR (Waist to Hip Ratio), BM (Bone Mass). The results have shown that there was a not statistically significant difference after the 6 – week program neither in body composition and somatotypes. Since this program did not have a big influence on body composition we could say that complex training influences body composition should be further researched.

Validation of a Video-Based Performance Analysis System (Mediacoach®) to Analyze the Physical Demands during Matches in LaLiga.

The aim of the present study was to assess the accuracy of a multi-camera tracking system (Mediacoach®) to track elite football players’ movements in real time. A total of 207 observations of 38 official matches from Liga 1, 2, 3™ (2nd Spanish Division, season 2017/18) were included in the study (88 defenders, 84 midfielders, and 35 attackers of the same team). Total distance (TD, m) distance in zone 4 (DZ4) at a speed of 14–21 km/h, distance in zone 5 (DZ5) at a speed of 21–24 km/h (DZ5), distance in zone 6 (DZ6) at a speed of ≥24 km/h, maximum speed (km/h), and number of sprints (actions above 24 km/h) were registered with the Apex® GPS system (STATSports™, Newry, N. Ireland) and Mediacoach® semi-automatic tracking system (LaLiga™, Madrid, Spain). The level of agreement between variables estimated by the two systems was analyzed. Bias was also calculated by deducting the GPS estimated value from the video estimated value, and then dividing the difference score by the GPS estimated value. All variables showed high ICC values (>0.75) and very large correlations (r > 0.70). However the video-based performance analysis system overestimated the results obtained in the different speed zones (DZ5: +16.59 ± 62.29 m; LOA95%: −105.49 to 138.68; DZ6: +93.26 ± 67.76 m; LOA95%: −39.55 to 226.07), the number of sprints (+2.27 ± 2.94; LOA95%: −3.49 to 8.02), and the maximum speed (+0.32 ± 1.25 km/h; LOA95%: −2.13 to 2.77). The maximum bias was found in DZ6 (47%). This demonstrates that Mediacoach® is as accurate as a GPS system to obtain objective data in real time, adapted to physical and movement demands of elite football, especially for total distance and distances traveled at medium speeds.
