Kayla’s Anatomy and Physiology lab group consists of herself…
Kayla’s Anatomy and Physiology lab group consists of herself and two other lab partners, Amy and Zurrie. Kayla is the subject in the same experiment you are performing today. Her lab partners are unfriendly and uninterested in performing the experiment. At 80 seconds, one of her partners says “Come on, you’re not even trying. Is that the best you can do?” The data for Kayla’s experiment are given in the table below: When comparing the 60-80 and 80–100 time intervals, Kayla’s grip strength and electrical activity both decreased during the 80–100 interval. If these decreases are due to negative coaching, how could this be explained in terms of the role of the brain in fatigue and resisting fatigue?
