Blog Post #2: Project Plan

1. Research Roadmap (Blog Posts #3, #4, and #5)

To examine how sleep deprivation impacts reaction time and decision-making in high school athletes, I am breaking my research down into three distinct phases.

Round 1 (Blog Post #3) — Neural Transmission & Visual-Motor Reaction Time

I will start by researching the neurological side of sleep loss. When an athlete is fatigued, processing speed in the prefrontal cortex slows down, directly delaying how fast the brain sends signals through the central nervous system to the muscles. Investigating simple versus choice reaction time tests will show why a sleep-deprived brain struggles to track fast-moving objects or execute immediate physical adjustments.

Round 2 (Blog Post #4) — In-Game Decision-Making, Spatial Awareness & Risk Assessment

This step focuses on tactical choices and cognitive performance under pressure. I will examine how sleep restriction impairs cognitive-motor control, spatial orientation, and response inhibition, which is the brain’s ability to filter out distractions and prevent hasty errors. This will help explain why exhausted athletes tend to make more unforced errors, misread plays, or hesitate during crucial moments in a game.

Round 3 (Blog Post #5) — Physical Output vs. Mental Recovery & Practical Solutions

The final post will address an interesting finding in sports science: while raw physical power like sprint bursts or jump height can sometimes hold up during partial sleep loss, mental focus and reaction times take a direct hit. I will explore realistic recovery strategies, such as target sleep extension, strategic napping, and routine adjustments that high school students can actually stick to while managing school and sports.

3. Real-World Impact

Personal Impact

As a student-athlete balancing club and school teams alongside high school coursework, late nights and early morning practices are part of my regular routine. Researching this question gives me a clear look at what is actually happening to my nervous system when I trade sleep for late-night studying or early workouts. It will help me make smarter choices about my own sleep schedule so I can perform at my best on game day without sacrificing grades or health.

Community Impact

In high school sports culture, there is often a mindset that pushing through exhaustion is just part of being dedicated. Athletes, coaches, and parents routinely treat sleep as an afterthought compared to late-night homework or extra training sessions. By laying out the actual data on reaction time, cognitive lag, and injury risk, this project can help start a realistic conversation in local athletic programs about treating rest as a key part of training rather than a weakness.
