Sometimes muscles and tendons get injured when a person starts doing an activity before they have warmed up properly. A warm up is a slow increase in the intensity of a physical activity that prepares muscles for an activity. Warming up increases the blood flow to the muscles and increases the heart rate. Warmed-up muscles and tendons are less likely to get injured. For example, before running or playing soccer, a person might jog slowly to warm muscles and increase their heart rate. Even elite athletes need to warm up ( Figure below ).
Kylie and Taylor are taking an exercise class at the local gym together. Before class, Kylie does a warm-up to stretch her muscles. Taylor does not do a warm-up before class.
Is Taylor more or less likely to suffer a muscle or tendon injury than Kylie?
