What are the symptoms of bonking during physical activities?

1. Muscle cramps and spasms

2. Light-headedness and lack of coordination

3. Overconfidence and increased energy

4. Rapid heartbeat and shortness of breath

The correct answer is: Light-headedness and lack of coordination

Bonking, also referred to as hitting the wall, is a phenomenon that often occurs during prolonged physical activities when an athlete's glycogen stores are depleted. This leads to a significant drop in energy, resulting in specific symptoms. Light-headedness and lack of coordination are primary indicators of bonking. When glycogen stores are low, the brain doesn't receive the glucose it needs to function properly, which can cause dizziness and confusion. Additionally, a lack of coordination arises because the normal energy and focus required to maintain physical balance and skill execution diminish. This combination makes it hard for an individual to perform effectively and safely. The other options highlight symptoms not typically associated with bonking. Muscle cramps and spasms, while common in physical exertion, are not the direct result of bonking itself, but rather can stem from dehydration or electrolyte imbalances. Overconfidence and increased energy are contrary to the feelings experienced during bonking, as it involves a significant energy deficit and loss of motivation. Lastly, a rapid heartbeat and shortness of breath would more likely relate to cardiovascular stress or exertion levels rather than the specific symptoms of bonking.
