Explanation:

Muscle contractions involve metabolic processes. During muscle - contraction, energy is released and part of it is dissipated as heat, which helps maintain body temperature and is important for overall body functioning. Lactic acid is produced during anaerobic respiration in muscles but is not the main product important for overall functioning in the way heat is. Pyruvate is an intermediate in cellular respiration. Water is a by - product of many metabolic reactions but not the key factor generated by muscle contractions for overall body function here.

Answer:

heat
