• How much time do you think you spend sitting each day? One study says you’re wrong.

    An interesting study looked at quantifying the amount of time people sit in three situations including during work hours, leisure time during a work day and during leisure days. Scientists were looking to validate self-reported measures against objective measures.

    To get impartial measures, they outfitted 26 office workers with accelerometers and customized software to obtain accurate, objective, measures of movement over a seven-day period.

    After the seven-day period scientists had the workers fill out a questionnaire to self-report sitting time, retrospectively. Scientists were looking for total sitting time and longest continuous time with uninterrupted sitting during the three situations.

    What did they find?

    “No significant correlations were found between objective and self-reported sitting time.”

    That’s right, the two measures (objective gathered with instrumentation and self-reported using memory after one to seven days) had zero correlation.

    This makes me wonder how many athletes are inaccurately reporting exercise time, intensity or other measures when they fill out a training log after one or more days have passed.

    What about you? Is your training plan journaling accurate?
