Gaming has evolved into a cultural phenomenon with a global reach, captivating millions of individuals. Nevertheless, little is known about this population. We aim to physiologically characterise the Portuguese gamers, bearing in mind that phase angle (PhA) is a general indicator of health, to check possible correlations between body composition, strength, and nutrition. A sample of 35 male gamers (individuals who play video games) was evaluated for anthropometry; body composition through DXA for whole-body bone mineral content (BMC), fat-free mass (FFM, kg), fat mass, and visceral adipose tissue, and through BIA (bioelectrical impedance analysis) for total body water (TBW), water pools (extracellular water and intracellular water, ICW), and PhA; strength through maximal isometric handgrip strength using a dynamometer; and nutritional intake using a three-day food record. Results show that participants are within reference metrics for all the analysed variables except regarding protein and carbohydrate intake (all values are above and below the Acceptable Macronutrient Distribution Ranges, respectively). A positive correlation was observed between PhA and TBW, ICW, handgrip strength, BMC and FFM, and a negative correlation with fat mass (absolute, percentage and visceral). In conclusion, PhA correlates with body composition variables, which aligns with previous research as a predictor of health and performance.
游戏已发展成为一种具有全球影响力的文化现象，吸引了数百万人。然而，人们对这一群体知之甚少。我们旨在对葡萄牙游戏玩家进行生理特征描述，考虑到相位角（PhA）是健康的一个综合指标，以检查身体成分、力量和营养之间可能存在的相关性。对35名男性游戏玩家（玩电子游戏的人）的样本进行了人体测量评估；通过双能X线吸收法（DXA）测量全身骨矿物质含量（BMC）、去脂体重（FFM，千克）、脂肪量和内脏脂肪组织，以分析身体成分，并通过生物电阻抗分析（BIA）测量全身水含量（TBW）、水池（细胞外水和细胞内水，ICW）和PhA；使用测力计通过最大等长握力测量力量；并使用三天食物记录评估营养摄入量。结果表明，除蛋白质和碳水化合物摄入量外（所有值分别高于和低于可接受的宏量营养素分布范围），参与者在所有分析变量的参考指标范围内。观察到PhA与TBW、ICW、握力、BMC和FFM呈正相关，与脂肪量（绝对值、百分比和内脏脂肪量）呈负相关。总之，PhA与身体成分变量相关，这与之前作为健康和表现预测指标的研究结果一致。
