Sniper Keeps His Cool | Fight Science

What is a key technique snipers use to improve accuracy by minimizing body movement?

• Holding their breath for a long time.

• Shooting exactly between heartbeats.

• Drinking a lot of water to stay hydrated.

• Wearing special gloves to steady their hands.

How does extreme heat affect a person's body, making it harder to perform precise tasks?

• It makes muscles stronger and more agile.

• It causes dehydration and increases heart and breathing rates.

• It improves concentration and focus.

• It makes the body feel lighter and more relaxed.

What methods were used to monitor the sniper's body during the experiment?

• A stopwatch and a thermometer.

• A bio-harness, a temperature-sensing pill, and thermal imaging.

• Blood pressure cuff and a pulse oximeter.

• A heart rate monitor and a sweat collection device.

What physiological process causes a sniper's trigger finger to move slightly, and how does the sniper minimize this effect?

• Muscle fatigue; by taking frequent breaks.

• Blood surging with each heartbeat; by slowing down breathing and heart rate.

• Nerve impulses; by using a specialized trigger.

• Sweating; by wearing absorbent gloves.
