Relationship of Body Core Temperature and Warm-up to Knee Range of Motion.
This study examined the effects of submaximal, treadmill exercise-induced body core temperature (BCT) increase on selected knee range of motion (ROM). Twenty males, 18-35 years old, were tested (randomized crossover) for ROM, BCT, and heart rate (HR), followed by either Treatment I (20 minutes of rest) or Treatment II (20 minutes of submaximal running). The two treatments were subsequently followed by a two-minute passive stretch. Range of motion was assessed before and after passive stretch treatment intervention. Treatment means differed for BCT and HR (p < 0.001) but not for ROM after exercise intervention. It was concluded that 20 minutes of exercise increased BCT (>1 degrees C) but had no effect on knee ROM. J Orthop Sports Phys Ther 1991;13(3):126-131.
