Randomized Controlled Trial Comparative Study Clinical TrialLow intensity physical training in older subjects.
This study was designed to evaluate the effects of a low intensity general training program (< 50% of heart rate reserve) on physical fitness of healthy older subjects, by comparing maximal and submaximal indices of training response. ⋯ Thus, it appears that a low intensity general training similar to that followed in the present study may represent a good means to improve physical fitness in healthy elderly people. Similarly, this study supports the effectiveness of evaluation tests based on submaximal responses to exercise in this population.

Case ReportsApplying physiological principles and assessment techniques to swimming the English Channel. A case study.
This study presents the use of physiological principles and assessment techniques in addressing four objectives that can enhance a swimmer's likelihood of successfully swimming the English Channel. The four objective were: (1) to prescribe training intensities and determine ideal swimming pace; (2) to determine the amount of insulation needed, relative to heat produced, to diminish the likelihood of the swimmer suffering from hypothermia; (3) to calculate the caloric expenditure for the swim and the necessary glucose replacement required to prevent glycogen depletion; and (4) to determine the rate of acclimatization to cold water (15.56 C/60 F). ⋯ Finally, the data from the cold water immersions suggested that acclimatization occurred following two weeks of immersions. There results were provided to the swimmer and utilized in making decisions in preparation for the swim.
