BMI Heart Rate Exercise Scifair Projects

Age and Exercise

A person's health is impacted by many things. It is particularly impacted by their age and the amount of exercise that they get.

Objectives/Goals

The objective of the project was to figure out whether age or BMI played a greater role in a child's heart rate's response to excercise. This year we wanted to see if controlling the food intake would affect the results. We also controlled other aspects of the experiment too, to see what affect it had.

Methods/Materials

Methods: Find Children that are willing to have their BMI measured and are willing to run; Measure distance for each age group (6 yr. olds- 25 yards, 12 yr. olds- 50 yards and 15 yr. olds- 100 yards); Measure each child's height and weight to calculate BMI; Measure heart rate before run and have children run, then measure heart rate after the run; Record results and continue procedure for each child.

Materials: 36 children (Three Age Groups: 6, 12, 15 yr. olds, 3 abnormal BMI kids for each group, 3 normal BMI kids for each age group, female and male); Heart Rate Monitor; Weight Scale; Measuring Tape; Masking Tape; Note Cards.

Results

This year's results greatly differed from last year's results. This year our data was supported by proven research. Our data showed that normal weight people had lower heart rate's than overweight and underweight people. This was true through all age groups. Because of this we concluded that BMI had a greater affect on heart rate than age. Last year's result were the exact opposite and were not supported by research.

Conclusions/Discussion

My data showed slight differences in the brain activity of casual and excessive gamers but these differences are not significant. Other studies have shown that changes in brain activity do occur while playing video games but the extent of these changes and their long term effect is yet to be determined. My project observes EEG activity of 2 groups of video game players; casual and excessive. School provided 3rd party contributor
