Exposure to carbon monoxide and nitrogen dioxide in enclosed ice arenas

This article summarises the latest information on the adverse cardiorespiratory effects of exposure to carbon monoxide (CO) and nitrogen dioxide (NO2) in enclosed ice rinks. Sources of CO and NO2 emissions are identified, current standards for these agents, as well as methods of controlling the emissions, dispersion, and evacuation of these toxic gases are presented. A detailed literature search involving 72 references in English and French from research conducted in North America and Europe was used. Material was from peer reviewed journals and other appropriate sources. Air pollutants such as carbon monoxide (CO), and nitrogen dioxide (NO2) which are present in enclosed skating facilities, may exacerbate a pre-existing pathogenic condition in those people who spend considerable time in these environments. Considering the popularity of ice hockey, short track speed skating, and figure skating, and the hundreds of hours that a sensitive person may spend each year in these environments, it would seem appropriate to seek more definitive answers to this important health problem. From the findings and conclusions of the research reviewed in this paper, 10 recommendations are listed.

Forensic Kinesiology: Foundations of an Interdiscipline for Accident/Crime Investigation

Kinesiology is the study of human movement, and comprises several disciplines, each devoted to a specific aspect of human activity, each with its own set of principles and methods to assess and analyze movement. Forensic kinesiology is the application of kinesiological techniques to accident/crime investigation; specialists in this field can use various tools and procedures to measure, analyze, model, and determine the movement sequences involved in events under investigation. This article will highlight major subdisciplines of kinesiology most relevant to forensics, present the key assessment and analytical tools used by kinesiologists, and demonstrate how both the principles and the practices of kinesiology can be applied to accident/crime investigation.

A Proposed Interdisciplinary Curriculum in Forensic Kinesiology

To meet the ever-increasing demand for expertise in human movement as applied to civil and criminal litigation, both private and public organizations have begun to seek the help of highly trained kinesiology specialists with advanced graduate-level university education and training. This paper will begin by identifying the key elements of the emerging specialization/subdiscipline of forensic kinesiology. Further discussion will outline the requirements for a university-based, graduate-level program designed to prepare students for specialization in forensic kinesiology. Based on this discussion, a proposed interdisciplinary curriculum will be presented.

Advanced 3S Stretching Exercises for Figure Skaters, Gymnasts, Divers, and Dancers

This chapter focuses on advanced stretching exercises for individuals wishing to achieve a high level of flexibility in the region of the hips, particularly figures skaters, gymnasts, divers, and dancers. Appropriate advanced 3S exercises will be presented.

Flexibility and Exercise

Stretching exercises have long been advocated as a means of improving performance, reducing the risk of injury, and facilitating rehabilitation after injury. However, there is conflicting evidence in the literature regarding the possible benefits of flexibility training. In sport, flexibility training programs are largely based on a coach’s or trainer’s opinion, which often derives from personal experience, sometimes in conjunction with a limited or uncritical reading of the literature. The available literature, furthermore, varies widely in quality, from tightly controlled, well-designed experiments to experiments that are poorly constructed and draw unwarranted conclusions. Many published articles violate accepted research standards yet have nonetheless influenced practitioners to form a number of erroneous beliefs.

Stretching the Major Muscle Groups of the Trunk and Neck

In this chapter, we present appropriate stretching exercises for the major muscle groups of the trunk and neck. All four methods (3S, yoga, slow/ static, and dynamic) will be covered for the trunk. For the neck, we recommend a very gentle, active range of motion stretch.

Stretching the Major Muscle Groups of the Upper Limb

In this chapter, we present appropriate stretching exercises for the major muscle groups of the lower limb. All four methods (3S, yoga, slow/static, and dynamic) are covered.

Stretching Techniques and Exercise Prescriptions

Flexibility is similar to aerobic capacity, strength, and neuromuscular endurance in being a trainable fitness parameter. Research into proper exercise prescriptions for slow/static, yoga, and dynamic stretching does not yet exist.1 Even basic guidelines for safe and effective use of these stretching techniques are generally missing. In this chapter, we fill this gap by offering practical guidelines for the use of yoga, slow/static, and dynamic stretching techniques, plus our scientifically based exercise prescription for the reversal of antagonists method (3S), a derivative of proprioceptive neuromuscular facilitation (PNF).

The Mechanisms of Flexibility Enhancement

Each stretching program that achieves an increase in flexibility causes some tissue adaptation. Because the 3S protocol elicits significantly greater alterations in the capacity of the targeted tissue to increase range of motion, we will focus our initial analysis on that method (the effect of slow/static and dynamic stretching will be addressed later in the chapter, when comparisons with 3S are discussed and illustrated).
