Dragon boat racing requires high physical activity levels during competition and training. The female athletic triad refers to a number of negative health consequences (e.g., amenorrhoea, low bone mineral density, and low energy availability) that may result from high physical activity in female athletes in parallel with inadequate dietary intake. This study aimed to estimate energy expenditure and dietary adequacy in female competitive dragon boat athletes. Following ethical approval, energy expenditure was assessed by use of Sensewear armbands (which measure movement as well as galvanic heat loss) on nine dragon boat athletes preparing for the Southeast Asian Games 2013. The mean estimated energy expenditure for the athletes was 2226 ± 711 kJ/day. Mean total energy, recorded using three-day food diaries (6715 ± 2518 kJ/day) and energy availability (99 ± 56 kJ/kg/day), were low. Estimated micronutrient intake (calcium 699.3 ± 328.7 mg/day and iron 10.6 ± 4.7 mg/day) did not meet recommended daily allowances of 800 mg/day and 19 mg/day, respectively. The low intake of energy, calcium, and iron noted within this study could have negative effects on performance and short- and long-term health in female dragon boat athletes.
龙舟比赛在竞赛和训练期间需要高强度的身体活动。女性运动三联征指的是一些负面健康后果（如闭经、低骨矿物质密度和低能量可利用性），这些后果可能源于女性运动员高强度身体活动且饮食摄入不足。本研究旨在评估女子竞技龙舟运动员的能量消耗和饮食充足情况。获得伦理批准后，对9名备战2013年东南亚运动会的龙舟运动员使用Sensewear臂带（测量运动以及电流热损失）来评估能量消耗。运动员的平均估计能量消耗为2226±711千焦/天。使用三日食物日记记录的平均总能量（6715±2518千焦/天）和能量可利用性（99±56千焦/千克/天）较低。估计的微量营养素摄入量（钙699.3±328.7毫克/天和铁10.6±4.7毫克/天）分别未达到每日推荐摄入量800毫克/天和19毫克/天。本研究中所指出的能量、钙和铁的低摄入量可能会对女子龙舟运动员的表现以及短期和长期健康产生负面影响。
