Sports, Exercise & Health Science IA ideas: how do you choose one?
Choose an idea that fits the subject criteria and can be answered with evidence, a method, and resources you can access.
A strong SEHS IA is a small-scale scientific investigation with one focused research question, a clear independent and dependent variable, and primary data collected ethically from human participants or physiological measures. Link results to a specific SEHS principle or model.
Which research questions fit Sports, Exercise & Health Science IA?
The questions below are starting points to adapt to your own variables, evidence, and assessment task.
How does caffeine affect resting heart rate and reaction time in the 30 minutes after ingestion?
Variables · IV: caffeine dose or placebo. DV: resting HR and reaction time at 5-min intervals. Control: same participant, time of day, hydration, prior sleep.
How does warm-up duration affect vertical jump height?
Variables · IV: warm-up time. DV: jump height from a mat or app. Control: protocol, footwear, rest between trials, time of day.
How does arm span correlate with standing broad jump distance?
Variables · IV: arm span bands. DV: jump distance. Control: footwear, take-off line, warm-up, tester.
How does music tempo affect 200 m running performance?
Variables · IV: music tempo. DV: split time and post-run HR. Control: same runner, course, warm-up, footwear.
How does breathing technique affect breath-hold time?
Variables · IV: breathing instruction. DV: breath-hold time. Control: same participant, rest period, posture, time of day.
How does prior sleep duration affect reaction time?
Variables · IV: self-reported sleep hours. DV: reaction time. Control: same test, time of day, caffeine, screen brightness.
How does hamstring flexibility affect balance on a wobble board?
Variables · IV: sit-and-reach score band. DV: balance time. Control: footwear, surface, same leg, visual input.
How does rest interval affect repeat-sprint performance?
Variables · IV: rest interval. DV: sprint time and fatigue index. Control: distance, start protocol, footwear, surface.
How does hand dominance affect pegboard speed and accuracy?
Variables · IV: hand used. DV: time and error count. Control: same task, posture, practice block, time of day.
How does target motion affect ball-tracking anticipation?
Variables · IV: target motion. DV: anticipation error in ms. Control: viewing distance, screen brightness, experience.
How does caffeine dose affect aiming steadiness?
Variables · IV: caffeine dose or placebo. DV: aiming error in mm. Control: same participant, time of day, sleep, hydration.
How does warm-up intensity affect post-exercise sit-and-reach?
Variables · IV: warm-up intensity. DV: sit-and-reach distance. Control: same participant, stretch duration, footwear, time of day.
