Metabolic analysis systems require binary sex input, conflating biological sex with gender, limiting inclusivity. This study aimed to determine whether sex input altered metabolic or pulmonary variables during self-paced walking and running. Twenty adults completed two 5-min walking and running trials under both female (FC) and male (MC) input conditions in randomized order. Dependent -tests determined differences between conditions; -values < 0.05 were considered significant, and effect sizes were calculated. No significant within-participant differences were found between FC and MC for any variable. During walking, mean relative VO (mL/kg/min) was 11.13 ± 2.73 (FC) and 10.81 ± 2.39 (MC), = 0.08, = 0.93; mean energy expenditure (kcal) was 18.28 ± 4.74 (FC) and 17.86 ± 4.33 (MC), = 0.12, = 0.94. During running, mean relative VO was 28.80 ± 5.89 (FC) and 28.82 ± 6.06 (MC), = 0.90, = 0.98; mean energy expenditure was 45.79 ± 13.08 (FC) and 45.55 ± 12.26 (MC), = 0.99, = 0.98. Binary sex input in the TrueOne 2400 system did not affect variables, supporting inclusive sex and gender data collection to improve research ethics, accuracy, and representation of gender-diverse people without compromising integrity.
代谢分析系统需要输入二元性别，将生物性别与社会性别混为一谈，限制了包容性。本研究旨在确定在自主节奏的步行和跑步过程中，性别输入是否会改变代谢或肺部变量。20名成年人按照随机顺序在女性（FC）和男性（MC）输入条件下完成了两次5分钟的步行和跑步试验。采用配对t检验确定不同条件之间的差异；p值<0.05被认为具有统计学意义，并计算效应量。在任何变量上，FC和MC之间均未发现显著的参与者内部差异。步行期间，平均相对VO₂（mL/kg/min）分别为11.13±2.73（FC）和10.81±2.39（MC），p = 0.08，d = 0.93；平均能量消耗（kcal）分别为18.28±4.74（FC）和17.86±4.33（MC），p = 0.12，d = 0.94。跑步期间，平均相对VO₂分别为28.80±5.89（FC）和28.82±6.06（MC），p = 0.90，d = 0.98；平均能量消耗分别为45.79±13.08（FC）和45.55±12.26（MC），p = 0.99，d = 0.98。TrueOne 2400系统中的二元性别输入不会影响变量，这支持了包容性的性别数据收集，以提高研究伦理、准确性以及对性别多样化人群的代表性，同时不损害数据完整性。
