The metabolic energy will be 197.03 J. From the given condition, the body is 20.6 % efficient.
Work is defined as the product of applied force and the distance through which the body is displaced on which the force is applied.
From the law of conservation of energy, the energy is equal to the work done;
Potential Energy = Work done
Potential Energy = mgh
Potential Energy = (75 kg) ×(9.8 m/s²)×(1.3 m)
Potential Energy = 956.475 joule.
From the given condition, the body is 25 % efficient;
The metabolic energy is found as;
Metabolic energy = 20.6 % of E
Metabolic energy = 20.6 % of 956.475 J
Metabolic energy = 197.03 J
Hence,the metabolic energy will be 197.03 J
