research and practice. In this commentary, I will expand on their recommendations by proposing that exercise scientists should more frequently utilize a specific qualitative research design: case studies. In exercise science, case study designs are mostly used to acquire knowledge about the training

In a recent issue of this journal, Halperin 1 discussed the merits of case studies as a means to bridge the gap between science and practice. It has been suggested that traditional forms of scientific study are not “user friendly” for coaches because they rely upon group-based statistical analyses

. Squash is an indoor sport. Individuals who perform indoors are at an increased risk of vitamin D deficiency ( Angeline et al., 2013 ). In athletes, vitamin D deficiency may impair muscle function, compromise the immune system, and impair bone health ( Need et al., 2000 ). The aim of this case study was
Some of the nutritional concerns of female athletes are highlighted in this case study of a 20-year-old woman who wants to lose 16% of her body weight to qualify for the position of coxswain on a national crew team. These concerns include adequacy of vitamin, mineral, protein, and carbohydrate intake as well as amenorrhea and pathogenic eating behaviors.

Professional boxing is a combat sport categorized into a series of weight classes. Given the sport’s underpinning culture, boxers’ typical approach to “making weight” is usually via severe acute and/or chronic energy restriction and dehydration. Such practices have implications for physical performance and also carry health risks. This article provides a case-study account outlining a more structured and gradual approach to helping a professional male boxer make weight for the 59-kg superfeatherweight division. Over a 12-week period, the client athlete adhered to a daily diet approximately equivalent to his resting metabolic rate (6–7 MJ; 40% carbohydrate, 38% protein, 22% fat). Average body-mass loss was 0.9 ± 0.4 kg/wk, equating to a total loss of 9.4 kg. This weight loss resulted in a decrease in percent body fat from 12.1% to 7.0%. In the 30 hr between weigh-in and competition, the client consumed a high-carbohydrate diet (12 g/kg body mass) supported by appropriate hydration strategies and subsequently entered the ring at a fighting weight of 63.2 kg. This nutritional strategy represented a major change in the client’s habitual weight-making practices and did not rely on any form of intended dehydration during the training period or before weighing in. The intervention demonstrates that a more gradual approach to making weight in professional boxing can be successfully achieved via a combination of restricted energy intake and increased energy expenditure, providing there is willingness on the part of the athlete and coaches involved to adopt novel practices.
