Educational Boxing Is Worth Becoming a Template for Building up Concussion Prevention Means in Children and Adolescents Sports  [PDF]

Advances in Physical Education (APE) , 2013, DOI: 10.4236/ape.2013.31008
Abstract: After comparing the means of concussion prevention used in educational boxing with similar means used in other sports practiced by children and adolescents, we noted that the exclusive use of light touches instead of blows in competitions of educational boxing is an original means of preventing concussion, acting on the direct cause rather than on the possible victim of concussion. We have then predicted that educational boxing is possibly the concussion-free form of competition boxing and that it is possibly chronic damage-free. If our predictions are fulfilled, educational boxing may serve as a template for building up concussion prevention means in all sports. Moreover, we would better go on popularizing the practice of educational boxing which is less likely to induce concussion than amateur and professional boxing; which has had more license owners than the two latter the 2004-2005, 2005-2006 and 2006-2007 boxing seasons in France; and which is practiced almost exclusively by children and adolescents in France. Despite the fact that light touches force of impact is sub-concussive, we need research work be undertaken in order to know whether light touches are harmless in educational boxers having had many fights and to know the occurrence frequency of unexpected concussions from light touches that turn to unintentional counter- punches.

The aim of the present study is not to provide the reader with a proof of astrology’s validity. The present study has been undertaken in the aim of providing the coach with an original tool for identification of the candidates more advantaged than others to boxing practice, in the case that the coach has too numerous candidates to deal with. Microsoft Office Excel 2007 program has been used in the analysis of data gathered from BoxRec.com, the web based database, about the World top 100 male boxers BoxRec.com-rated, retired on March 26th, 2013. The study has shown that boxing performance may be influenced by pertaining of the boxer to given zodiacal signs: 1) Regarding all victories pulled together, the most disadvantaged are Sagittarius signs. As other zodiacal signs related to the element Fire, they probably rarely display tactful behavior. Their resulting impulsiveness may make them neglectful of their defense. 2) Regarding all losses pulled together, the most disadvantaged are Aquarius signs. As other zodiacal signs related to the element Air, they probably think too much before they act; and they tend to rise above conflict and to float around it. All that may affect negatively their attack velocity and defense velocity. 3) Regarding non-KO victories and KO losses, the most advantaged are Scorpio signs. Contrary to other Water signs which are used to detest all form of conflict, they often seek out challenges and problems, subliminally realizing that such challenges call forth their greatest strength and resources. That may probably help them not to neglect their attack, what is expectable in other Water signs. 4) Regarding all victories pulled together, all losses pulled together, and non-KO losses, the most advantaged are Virgo signs. Regarding KO victories, the most advantaged are Taurus signs. As other Earth signs, when driven back against a wall, Virgo and Taurus signs are capable of hitting the obstacle hard with full force. That is particularly true of Taurus, the fixed Earth, who will never seek out conflicts but who is capable of surprising power. The known soundness of Earth signs may help Virgo and Taurus signs to control both their attack and defense actions, performing them only when they feel that they are going to be successful. 5) Regarding boxers life spans, the most advantaged are Libra and Sagittarius signs.

Boxing Competitors Being the Exception; Judo, 1500 m Running, and Marathon Running Competitors at the 2012 London Olympic Games Held Inadequate Ages, Heights and/or Weights That Contributed to the Humiliating Defeats of Democratic Republic of the Congo  [PDF]

Abstract: There exist many factors that may have influenced the performance of the only four Democratic Republic of the Congo (DRC) competitors at the 2012 London Olympic Games. However, in the present article, the attention is focused only on available anthropometric factors. Computer carried out the analysis of the ages, heights and/or weights of all the competitors of some divisions at the 2012 London Olympic Games [super heavyweight male boxers (more than 91 kg); male judokas weighing 100 kg and over; women who ran the 1500 m race; and men who ran the marathon]. An examined clip showed the contribution of factors others than anthropometric to the early defeat of the Congolese boxer Mwamba Meji at the 2012 London Olympic Games (inadequate wearing of boxing helmet, wearing of boots inappropriate to boxing practice, the imperfection of boxing guard, errors of tactics, face showing fear of the opponent’s attacks). None of the three aforesaid anthropometric factors contributed to the boxer’s defeat. Inadequate anthropometric factors that caused early defeats of the three other Congolese competitors at the 2012 London Olympic Games were: 1) the relative age of the male judoka Mandembo Cedric when compared with that of his opponent, and his too short absolute height; 2) the too young age, the too short height and the too light weight of the 1500 m female runner Ilunga Sankuru Chancel; as well as 3) the too young age and the too short height of the marathon male runner Ilunga Zatara Mande.
Boxing Performance of Most Boxers Is Directed by Their Ectomorphy Ratings towards Lowest Percentages of Victories and Highest Percentages of Losses  [PDF]

Advances in Physical Education (APE) , 2016, DOI: 10.4236/ape.2016.64036
Abstract: High level performance is influenced by the three somatotype components: endo- morphy, mesomorphy, and ectomorphy. Mesomorphy is the most important of the three for boxing practice. An increase in ectomorphy rating is always accompanied by a decrease in mesomorphy rating. Is thus a higher ectomorphy rating overtaxing and/or counterproductive for boxing performance? That is the basis of the present study and the results follow. Boxing could overtax the practitioner the least at the ectomorphy rating value of 2.5. With increasing and with decreasing rating values from 2.5, boxing could overtax even more the practitioner. At the ectomorphy rating of 2.5, boxing is counterproductive: one finds lowest percentages of KO victories and of all victories (KO and non-KO) pulled together; as well as highest percentages of non-KO losses and of all losses (KO and non-KO) pulled together. With boxers ec- tomorphy rating moving from 2.5 towards 0.1 or towards 5.1, there are: an increase in all victories (KO and non-KO) pulled together percentages and the consequent decrease in all losses (KO and non-KO) pulled together percentages; an increase in KO victories percentages and the consequent decrease in non-KO victories percentages; and a increase in KO losses percentages and the consequent decrease in non-KO losses percentages. With boxer ectomorphy ratings increasing from 0.1 to 5.1, percentages of draws go on decreasing. Taking into account ectomorphy ratings could thus help organizers select boxers so as to increase the probability of a given decision: KO victory by Mike Tyson, non-KO victory by Ken Buchanan, for instance.
Almansba, Franchini and Sterkowicz Judo Specific Test Proposal (2007) Commentary  [PDF]

Open Journal of Molecular and Integrative Physiology (OJMIP) , 2018, DOI: 10.4236/ojmip.2018.82002
Abstract: The present commentary is aimed to contribute to the improvement of the judo specific test proposal elaborated and validated by Almansba, Franchini and Sterkowicz (2007) 1) with the aim of evaluating specifically the physical fitness of competing judo practitioners, 2) wishing the test to be representative both qualitatively and quantitatively of the effort sustained by the practitioners. All alone, the test proposal, which utilizes rapid repetitions of one judo technique off-balancing and body positioning by the same practitioner (Uchi-komi) may be usable instead of three non-judo specific tests: the vertical jump test of Sargent (1921), the multistage fitness test of Léger et al. (1984) and the Australian shuttle run test described by Cazorla et al. (2004). However, the judo specific test proposal 1) specificity is still to be increased and must ideally turn into test individualization (using the proposal as a template), as in judo, trained individuals have favorite techniques they use in preference to others; 2) represents competing judo practitioners efforts quantitatively but not qualitatively (throws are represented, but neither hold downs, arm-locks, strangle holds nor chokeholds); 3) brings subjects to physiological exhaustion but psychological exhaustion emotional component is left out of account. Uchi-komi utilized by the test proposal could better be replaced by continual completions of variable judo techniques by the same practitioner (Kakari-geiko) which allow the practitioner who is attacking by means of judo techniques (Tori) to utilize linked up techniques. Nevertheless, to date, the test proposed for assessing the suitability of judo practitioners to meet competition demands is the most judo specific and the most economic.

During the academic year 2016-2017, students aged 18 years and older in their second year at the University of Kinshasa Pharmaceutical Sciences Faculty have shown the following mean values, respectively of, cm height, kg weight, kg·m﹣2 BMI and unit-less ectomorphy: 1° non-sportsmen: 173.4 cm, 55.8 kg, 18.6 kg·m﹣2, and 4.8; 2° sportsmen: 174.2 cm, 63.6 kg, 20.9 kg·m﹣2, and 3.5; 3° non-sportswomen: 162.2 cm, 59.4 kg, 22.6 kg·m﹣2, and 2.2; 4° sportswomen: 161.5 cm, 52.4 kg, 19.9 kg·m﹣2, and 3.2; 5° all males students: 173.8 cm, 62.7 kg, 20.7 kg·m﹣2, and 3.6; 6° all female students: 160.4 cm, 54.5 kg, 20.6 kg·m﹣2, and 2.6; 7° all male and female students pulled together: 168.1 cm, 59.1 kg, 20.6 kg·m﹣2, and 3.2. Sports practice seems to increase in males but to decrease in females, height, weight and BMI; while it seems to decrease in males but to increase in females, ectomorphy rating. Sports practice could improve health situation of the population which is bad (14.4% of underweight BMI values instead of less than 5.0%). DRC is worth looking for the mean weight of the subjects enrolled in the experimentation that led to the direction for use adult recommended dose of each imported drug so as, if need be, to adapt it to DRC residents. Referencing values published by others have helped give examples of recruiting sportspersons so as to expect training to be rapidly successful and to expect sports practitioners to be at their best performance during competitions.

Objective: This paper aims at assessing outcomes following induction of labor and characteristics likely to predict vaginal delivery. Study design: This is a descriptive retrospective cohort study including all women with singleton pregnancies who delivered at term in the university clinics of Kinshasa, DR Congo, from January 01, 2006 until December 31, 2010. Induction was initiated regardless of cervical status. Methods of induction included: oxytocin perfusion, vaginal Misoprostol, intracervical insertion of the Foley catheter and amniotomy. Results of induction were compared in terms of failure of labor, cesarean section, fetal distress, and neonatal distress. Logistic regression was used to seek for independent contributing factors for adverse outcomes. Results: During the period of the study 115 patients at term (3.2%) were concerned with induction of labor. Means for maternal age, gestational age and weight at confinement were 30.5 ± 5.7 years, 37.95 ± 1.54 weeks and 69.3 ± 15.1 kg, respectively. The mean parity and gravidity were 2.4 ± 1.9 and 2.9 ± 1.9, respectively. The mean Bishop score was 6.2 ± 1.5 at the first induction, with 66 women (57.3%) having less than 7. Indications for induction were: preeclampsia (52 = 54.1%), premature rupture of membranes (34 = 29.5%), post term (17 = 14.6%), gestational diabetes (5 = 4.3%), stillbirth (5 = 4.3%), polyhydramnios (3 = 2.6%) and cardiopathy (1 = 0.8%). Methods of induction at the first attempt included: oxytocin (86 = 74.7%), vaginal misoprostol (20 = 17.3%), transcervical Foley catheter balloon (14 = 12.1%), and amniotomy (1 = 0.8%). Failure to induce uterine contraction at the first attempt was noted in 9/115 (7.8%) women. Vaginal delivery occurred in 78 (66.9%) women, and cesarean section in 34 (29.6%). The majority of cesarean sections were performed at the primary induction, most of them (29/34 = 85.3%) in women with bad Bishop score. Failure of induction was more likely to occur in association with high maternal weight (OR 6.8; CI 1.2 - 39.7), and somewhat birth weight (OR 2.1 but CI containing 1). Risk for cesarean section was increased in association with induction of labor in cases of high maternal weight (OR 10.3, CI 16.0 - 67.0), and somewhat of high birth weight (OR 2.3, but CI containing 1). Fetal distress was associated only with maternal weight (OR 15.7, CI 1.3 - 187.8), and neonatal distress only with Bishop score (OR 10.9, CI 1.1 - 108.0). Conclusion Induction of labor in our setting in order to get vaginal delivery is affected of a high risk

Abstract: Ce travail est motivé par les problèmes posés par la stabilité des puits forés dans des formations argileuses avec des boues de forage à base d'eau. En effet, les roches argileuses ou argilites (shales en anglais) ont la propriété d'absorber de l'eau, entra nant ainsi la déstabilisation des puits, soit par gonflement de certaines espèces minérales, soit par annulation de la pression de soutènement de la paroi par suite de la modification de la pression de pore. La déstabilisation peut être purement mécanique avec une plastification entra nant un cavage du trou, ou dépendre essentiellement des interactions physicochimiques entre le fluide de forage et l'argile. Le but de ce travail est donc de mettre expérimentalement en évidence les mécanismes susceptibles de jouer un r le dans les phénomènes évoqués, et de tenter de quantifier l'importance de ces mécanismes pour en tenir compte dans les modèles de calcul. Le système expérimental que nous utilisons est basé sur une cellule triaxiale perméable aux rayons X, et donc destinée à un fonctionnement sous scanner (tomographie). Ce système, con u et construit à l'Institut Fran ais du Pétrole (IFP), est nouveau et nous avons contribué dans le cadre de ce travail à sa mise au point. La démarche consiste à mettre un échantillon d'argile sous confinement au contact avec un fluide de composition déterminée et à voir si les composants de ce fluide migrent dans l'argile ou non. Bien entendu, la tomographie ne permet que d'avoir des densités globales avec des résolutions de loin supérieures à la dimension du pore d'un matériau argileux sous confinement. Il est donc évident que les indications fournies par cette méthode doivent être complétées avec d'autres types de méthodes pour arriver à une étude sélective de la migration des éléments en solution. Pour ce qui concerne le matériau, notre choix s'est porté sur l'argile de Boom en Belgique, d'une part pour sa disponibilité et, d'autre part, pour la grande quantité d'informations disponibles sur ce matériau. General ConsiderationsThis work deals with problems encountered regarding the stability of wells drilled in the clay material formations with water based muds. In fact, clays or shales have a property of taking water, thus causing the instability of wells either because of the swelling of some mineral species, or because the supporting pressure is suppressed by modification of the pore pressure. The aim here is to experimentally emphasize the principal mechanisms driving the phenomenon of instability, and to try to quantify the importance of these mechanisms in order t

Abstract: Aromatic compounds are inhibitors of methane biosynthesis in anaerobic treatment of solid wastes and industrial effluents. Anaerobic treatment of solid wastes and industrial effluents may be limited by the methanogenic bacteria inhibition exerted by these types of compounds, the production of biogas is not possible and the organic matter contained in the effluent is not reduced. These effluents poured in the nature can be the basis of the pollution. The objective of this study is to evaluate the effect of monosubstituted aromatic compounds functional groups on the methanogenic inhibition. The toxicity to acetoclastic methanogenic bacteria has performed in serum flasks, utilizing digested pig manure as inoculums, by measuring methane production. The nature of aromatic functional groups was observed to have a profound effect on the toxicity of the monosubstituted aromatics. Among the monosubstituted aromatic, the chlorobenzene was the most toxic with 50% of inhibition occurring at the concentration of 30.08 mg/l. In contrast, benzoic acid is the least inhibitory with IC50 of 2515.20 mg/l. The partition coefficient octanol/water (logPoct), an indicator of hydrophobicity, had a significant correlation with the methanogenic toxicity.

Inhibitory compounds are often found to be the leading cause of anaerobic reactor upset and failure since they are present in substantial concentration in wastewaters and organic solid wastes. Among these inhibitory compounds, organic compounds are mentioned and more especially aromatic compounds. The purpose of this work was to evaluate the effect of bisubstituted aromatics functional groups on the methanogenic inhibition. The toxicity to acetoclastic methanogenic bacteria has performed in serum flasks, utilizing digested pig manure as inoculums, by measuring cumulative methane production. The results obtained indicate that some general relationships exist between the bisubstituted aromatic structures and their inhibitory effects on methanogenic bacteria. This demonstrates sufficiently that the grafting of hydrophobic or hydrophilic substituent on the benzene or monofunctional aromatic compound, make the obtained compound more or less toxic as the case and that in the same order of toxicity. A significant correlation was obtained indicating that the partitioning of bisubstituted aromatics into lipophilic membranes in bacteria may have a role in the inhibition of methane biosynthesis.
