الطاقة، الكفاءة، الوزنالملخص
أحد أهداف بيئة العمل هو تحقيق الأداء الفائق وحماية العمل أثناء بعض المهام البدنية مع تقليل الاضطرابات العضلية الهيكلية وإهدار الطاقة. في الآونة الأخيرة، كانت هناك مخاوف من أن قياسات الجسم قد تساهم ليس فقط في زيادة الاضطرابات العضلية الهيكلية ولكن أيضًا في تقليل طاقة الفرد وكفاءة العمل. ولذلك، كان الغرض من هذه الدراسة هو دراسة تأثير وزن الجسم على كفاءة العمل من حيث إنفاق طاقة النشاط (AEE). تم إجراء قياسات AEE باستخدام Actiheart على 12 وضعية منسقة للجذع والكتف أثناء مهمة الحفر. تم استخدام عينات مستقلة من اختبار t والاختلافات المتوسطة لتحليل آثار وزن الموضوع على AEE. أظهرت النتائج أن AEE انخفض مع زيادة وزن الشخص (الدهون الحرة) (R2 0.62). وأن الأفراد الذين يعانون من ارتفاع وزن الجسم (الدهون الحرة) يكلفون أقل من AEE وبالتالي يكونوا أكثر فعالية.
