Explain how intensity could affect performance?

Generally, it is believed that competitors need an “optimal level of intensity.” This means that when intensity is too high or too low, performance can be affected. A high intensity level can decrease concentration, focus, and create problems with coordination, reaction time, strength, and endurance.

Some physical sensations can impact performance if the situation requires a great deal of concentration or accuracy such as golf or a performance sport. The increased adrenalin, heart rate, and muscle tension may actually interfere with performance. In addition, when intensity becomes too high a person might feel increased fatigue instead of energy which can cause slower reactions and reduced coordination. Increased intensity can also contribute to increased negativity, fear, anxiety, and feelings of hopelessness which interfere with performance of physical skills.
