Answer:
Hiccups can decrease the ability to continue exercising for a longer amount of time due to the interruption of normal breathing patterns. When hiccups occur, the diaphragm contracts involuntarily, leading to a sudden intake of air. This interruption can cause fatigue in the respiratory muscles and decrease the efficiency of cellular respiration, leading to less oxygen being transported to the working muscles. This lack of oxygen can result in premature fatigue and decreased exercise performance. Additionally, the distraction and discomfort caused by hiccups can cause a decrease in motivation and focus, further impacting exercise ability.
