There are over 600 million people in the world aged 60 years and over. This figure is expected to double by 2025 and to reach 2 billion by 2050 (1). Population ageing is characteristically accompanied by an increase in the burden of chronic non-communicable diseases such as diabetes, cardiovascular disease, cancers and renal failure. As a consequence, pressures on health systems worldwide will increase (1). Data produced by the National Renal Workforce Planning Group in 2002 (2), predicted that the demand for renal replacement therapy (RRT) will continue to rise beyond 2010 for many reasons one of those being demographic changes with an aging population. This will also have an impact on the numbers of patients predicted to commence dialysis and transplantation (Table 1). With this higher projection of patients requiring RRT, there is a need to look at new ways of working.

Cardiovascular fitness in a selected group of dentists.

Thirty-three dentists were studied as part of an exercise rehabilitation clinic in order to evaluate their cardiovascular capacity and coronary prone risk factors. Measurements were made of their physical work capacity, predicted maximal oxygen uptake, fatness, serum lipids and uric acid levels, pulmonary peak flow rates and personality Type A or B. The group as a whole exhibited a moderately high level of fitness and a very active life style which probably reflected their presence at a clinic of this type. Cardiovascular fitness varibles increased with age. This increase may be due to a need and desire on the part of the dentists to maintain their physical fitness as they become older. This need for improved self image may also be a factor in their joining an exercise rehabilitation clinic.

Interval training and performance.

Researchers, coaches and athletes have a variety of concepts of interval training, the only point of agreement being that interval training involves alternating bouts of exercise and recovery. The idea that interval training can be identified by a specific intensity, duration, or number of exercise bouts or by the amount or type of recovery between bouts of exercise is not valid. Rather, interval training has come to mean any type of intermittent training which, with manipulation of the number, intensity and duration of work bouts and amounts of recovery, is used to produce a particular type of stress on the body. There is general agreement that rather specific guidelines are available which determine the amount and intensity of work and the amount of rest necessary to produce specific results, and it is suggested that types of training be identified based on the specific characteristics of each particular type of training rather than placing all types of intermittent training in an all-inclusive category called 'interval training'. Further efforts should be made to continue investigations which help determine how much, how often and for whom the various types of intermittent training are beneficial.
