Ten competitive ballroom dance couples performed simulated competitive sequences of Modern and Latin American dance. Heart rate was telemetered during the dance sequences and related to direct measures of oxygen uptake and heart rate obtained while walking on a treadmill. Linear regression was employed to estimate gross and net energy expenditures of the dance sequences. ⋯ Males were estimated to expand 54.1 +/- 8.1 kJ.min-1 of energy during the Modern sequence and 54.0 +/- 9.6 kJ.min-1 during the Latin American sequence, while predicted energy expenditure for females was 34.7 +/- 3.8 kJ.min-1 and 36.1 +/- 4.1 kJ.min-1 for Modern and Latin American dance respectively. The results suggested that both males and females were dancing at greater than 80% of their maximum oxygen consumption. A significant difference between males and females was observed for predicted gross and net values of oxygen consumption (in L.min-1 and ml.kg-1 min-1).

All horse-related injuries presenting to an Accident Service over a two-year period were investigated. 237 patients presented. The injuries were not considerable in absolute number but were in severity. ⋯ At least seven life-threatening injuries were identified and there were other severe pelvic and spinal injuries. The wearing of protective head gear remains the most important safety measure.

Age, height and weight are intricately related to performance in a specific sporting activity. Optimum standards derived from 32 female Olympic finalists from two jumping events are listed as a sample from a much larger set of 824 finalists from 47 events. An example of variation is that high jumpers are taller by 6.3 cm and younger by 2.9 years than long jumpers. ⋯ They are also of use for trainers counselling athletes in the most appropriate selection of the event befitting her physique. Many sporting activities are found to be seriously biased in favour of the taller members of the population. This is a cause for concern as is the need for some remedial action.

This report discusses two cases referred on the same day to the Mersey Regional Neurosurgical Unit. Both patients bore positions of responsibility and each developed an extradural haematoma as a result of neglecting to wear the appropriate safety helmet for their respective sports. The two survived, without detectable morbidity, to learn the relevant lesson.

This survey studied the health and sleeping patterns of 92 physical education and sports science students highly involved in sport. A strong correlation was found between smoking and various complaints of ill health as well as between smoking and sleep duration and quality of sleep. The results suggest that there is a strong relationship between the constituents of tobacco smoke and poor sleeping habits.
