Abstract

The outsole of a running shoe must provide enough traction for the athlete to avoid slipping during running. What is unknown is whether there is any point to designing running shoe outsoles with traction above this minimum required traction. The purpose of this study was to investigate whether performance could be enhanced by increasing the outsole traction of a running shoe. A commercially available running shoe (Control) was compared against the same shoe model with the outsole modified with a higher traction rubber (High Traction). The available traction of each shoe was measured with a traction testing system. Twenty male athletes completed a maximal effort timed running course in both shoes on two different surfaces. When wearing the Control running shoe, the athletes were able to complete the course on an asphalt road surface at maximal effort without slipping. When completing the same course wearing the High Traction shoe, the subjects were able to perform the course even faster. Therefore, the results show that the role of running shoe outsole traction is not to merely provide adequate traction to avoid large scale slips, but can also help athletes enhance performance of high-traction tasks such as accelerations and changes in direction.

Abstract

At a meeting of the Council of the Royal Borough of Kensington on February 29th, ALDERMAN A. G. McARTHUR, Chairman of the Public Health Committee of the Council, brought up a Report as follows— “We have received replies from nineteen City and Borough Councils to the circular letter addressed to them by this Council protesting against the suggestion made by the Board of Agriculture and Fisheries that, before proceedings under the Sale of Food and Drugs Acts are instituted on analytical evidence in respect of milk there should be a preliminary investigation by an officer of the Local Authority, or that the milk producer should be given an opportunity of offering an explanation.

Abstract

We observe with pleasure that the French Analytical Control, which is known as the Controle Chimique Permanent Français, continues to make satisfactory progress. The value and importance of the system of Control cannot fail to meet with appreciation in France—as it cannot fail to meet with appreciation elsewhere—so soon as its objects and method of working have been understood and have become sufficiently well known. From the reports which appear from time to time in l'Hygiène Moderne, the organ of the French Control, it is obvious that a number of French firms of the highest standing have grasped the fact that to place their products on the market with a permanent and authoritative scientific guarantee as to their nature and quality, is to meet a growing public demand, and must therefore become a commercial necessity. An ample assurance that the Controle Chimique Permanent Français is a solid and stable undertaking is afforded by the facts that it is under the general direction of so distinguished an expert as M. Ferdinand Jean and that he is assisted by several well‐known French scientists in carrying out the very varied technical work required.

Abstract

In a previous article we have called attention to the danger of eating tinned and bottled vegetables which have been coloured by the addition of salts of copper and we have urged upon the public that no such preparations should be purchased without an adequate guarantee that they are free from copper compounds. Copper poisoning, however, is not the only danger to which consumers of preserved foods are liable. Judging from the reports of cases of irritant poisoning which appear with somewhat alarming frequency in the daily press, and from the information which we have been at pains to obtain, there can be no question that the occurrence of a large number of these cases is to be attributed to the ingestion of tinned foods which has been improperly prepared or kept. It is not to be supposed that the numerous cases of illness which have been ascribed to the use of tinned foods were all cases of metallic poisoning brought about by the action of the contents of the tins upon the metal and solder of the latter. The evidence available does not show that a majority of the cases could be put down to this cause alone; but it must be admitted that the evidence is in most instances of an unsatisfactory and inconclusive character. It has become a somewhat too common custom to put forward the view that so‐called “ptomaine” poisoning is the cause of the mischief; and this upon very insufficient evidence. While there is no doubt that the presence in tinned goods of some poisonous products of decomposition or organic change very frequently gives rise to dangerous illness, so little is known of the chemical nature and of the physiological effects of “ptomaines” that to obtain conclusive evidence is in all cases most difficult, and in many, if not in most, quite impossible. A study of the subject leads to the conclusion that both ptomaine poisoning and metallic poisoning—also of an obscure kind—have, either separately or in conjunction, produced the effects from time to time reported. In view of the many outbreaks of illness, and especially, of course, of the deaths which have been attributed to the eating of bad tinned foods it is of the utmost importance that some more stringent control than that which can be said to exist at present should be exercised over the preparation and sale of tinned goods. In Holland some two or three years ago, in consequence partly of the fact that, after eating tinned food, about seventy soldiers were attacked by severe illness at the Dutch manœuvres, the attention of the Government was drawn to the matter by Drs. VAN HAMEL ROOS and HARMENS, who advocated the use of enamel for coating tins. It appears that an enamel of special manufacture is now extensively used in Holland by the manfacturers of the better qualities of tinned food, and that the use of such enamelled tins is insisted upon for naval and military stores. This is a course which might with great advantage be followed in this country. While absolute safety may not be attainable, adequate steps should be taken to prevent the use of damaged, inferior or improper materials, to enforce cleanliness, and to ensure the adoption of some better system of canning.

Abstract

The Sanitary Committee of a certain County Council, strong with the strength of recent creation, have lately been animated by a desire to distinguish themselves in some way, and, proceeding along the lines of least resistance, they appear to have selected the Public Analyst as the most suitable object for attack. The charge against this unfortunate official was not that he is incompetent, or that he had been in any way negligent of his duties as prescribed by Act of Parliament, but simply and solely that he has the temerity to reside in London, which city is distant by a certain number of miles from the much favoured district controlled by the County Council aforesaid. The committee were favoured in their deliberations by the assistance of no less an authority than the “Principal” of a local “Technical School”;—and who could be more capable than he to express an opinion upon so simple a matter? This eminent exponent of scientific truths, after due and proper consideration, is reported to have delivered himself of the opinion that “scientifically it would be desirable that the analyst should reside in the district, as the delay occasioned by the sending of samples of water to London is liable to produce a misleading effect upon an analysis.” Apparently appalled by the contemplation of such possibilities, and strengthened by another expression of opinion to the effect that there were as “good men” in the district as in London, the committee resolved to recommend the County Council to determine the existing arrangement with the Public Analyst, and to appoint a “local analyst for all purposes.” Thus, the only objection which could be urged to the employment of a Public Analyst resident in London was the ridiculous one that the composition of a sample of water was likely to seriously alter during the period of its transit to London, and this contention becomes still more absurd when it is remembered that the examination of water samples is no part of the official duty of a Public Analyst. The employment of local scientific talent may be very proper when the object to be attained is simply the more or less imperfect instruction of the rising generation in the rudiments of what passes in this country for “technical education”; but the work of the Public Analyst is serious and responsible, and cannot be lightly undertaken by every person who may be acquainted with some of the uses of a test‐tube. The worthy members of this committee may find to their cost, as other committees have found before them, that persons possessing the requisite knowledge and experience are not necessarily indigenous to their district. Supposing that the County Council adopts the recommendation, the aspirations of the committee may even then be strangled in their infancy, as the Local Government Board will want to know all about the matter, and the committee will have to give serious and valid reasons in support of their case.

Abstract

An International Exhibition of Hygiene, Arts, Handicrafts, and Manufactures will be held in the Crystal Palace, Madrid, from September to November next, under the patronage of the Spanish Government. The participation of British exhibitors is particularly desired by the promoters, who state that the attendant expenses will be small. His Excellency the Spanish Minister of Commerce will be the Honorary President; the President of the Committee will be his Excellency the Duke of Tamames and Galisteo, Grandee of Spain, Senator, and ex‐Governor of Madrid. The American war on the one hand, and political changes on the other, have had the effect of seriously damaging the credit of Spain, and many exporters, in view of then existing difficulties, refused to trade until affairs became mere settled. To‐day, however, the Spanish Government are making every effort to restore the economical prosperity of their country. Markets have gained strength, commerce has quadrupled, imports have trebled, and exchange is greatly improved. Well‐advised manufacturers sell in quantity and at good prices, the demand being greater than the supply. Again, the immense natural richness of the Iberian Peninsula, which has not yet received the attention of enterprising and powerful capitalists in any proportion to its value, makes Spain one of those countries where industrial progress is the more certain. The decision to hold this exhibition is evidently a wise one, and considerable advantages may accrue to British manufacturers and merchants taking part therein. There appear to be ample guarantees to show that the undertaking may be supported with every confidence. We understand that all detailed particulars with reference to this important exhibition can be obtained from the Spanish representative in London, Mr. A. DONDERIS, Spanish Arts Exhibition, Compton House, 99A, Charing Cross Road, London, W.C.
