Answer:
Shivering thermogenesis.
Explanation:
The rate of heat production is increased by increasing muscle contraction by movement is shivering thermogenesis because nerve impulses are transmitted to the skeletal muscles by the hypothalamus which will result to contractions that will produce heat. 
Shivering thermogenesis is Contraction-mediated heat production High intensity shivering activates large muscles and produce more glycolysis which is then use as the main source for heat production
