CRESPO, NC, SL MULLANE, ZS ZEIGLER, MP BUMAN, and GA GAESSER. Effects of Standing and Light-Intensity Walking and Cycling on 24-h Glucose. Med. Sci. Sports Exerc., Vol. 48, No. 12, pp. 2503–2511, 2016. This study aimed to compare 24-h and postprandial glucose responses to incremental intervals of standing (STAND), walking (WALK), and cycling (CYCLE) to a sit-only (SIT) condition. Nine overweight/obese (body mass index= 29 T 3 kgImj2) adults (30 T 15 yr) participated in this randomized crossover full-factorial study, with each condition performed 1 wk apart. STAND, CYCLE, and WALK intervals increased from 10 to 30 minIhj1 (2.5 h total) during an 8-h workday. WALK (1.0 mph) and STAND were matched for upright time, and WALK and CYCLE were matched for energy expenditure (~ 2 METs). Continuous interstitial glucose monitoring was performed for 24 h to include the 8-h workday (LAB), after-work evening hours (EVE), and sleep (SLEEP). Three 2-h postprandial periods were also analyzed. Linear mixed models were used to test for condition differences. Compared with SIT
