A prospective examination of the impact of high levels of exercise training on sedentary behaviour

Abstract

The aim of this study is to determine changes in sedentary behaviour in response to extensive aerobic exercise training. Participants included adults who self-selected to run a marathon. Sedentary behaviour, total activity counts and physical activity (PA) intensity were assessed (Actigraph GT3X) for seven consecutive days during seven assessment periods (−3, −2, and —1 month prior to the marathon, within 2 weeks of the marathon, and +1, +2, and +3 months after the marathon). Models were fitted with multiple imputation data using the STATA mi module. Random intercept generalized least squares (GLS) regression models were used to determine change in sedentary behaviour with seven waves of repeated measures. Results: Twenty-three individuals (mean ± Sx: 34.4 ± 2.1y, 23.0 ± 1.9% fat, 15 women, 8 men) completed the study. Marathon finishing times ranged from 185 to 344 minutes (253.2 ± 9.6 minutes). Total counts in the vertical axis were 1,729,414 lower one month after the race, compared with two months prior to the race (peak training). Furthermore, counts per minute decreased by 252.7 counts·minute−1 during that same time period. Daily sedentary behaviour did not change over the seven assessment periods, after accounting for age, gender, per cent body fat, wear time, marathon finishing time, and previous marathon experience. This prospective study supports the notion that PA and sedentary behaviours are distinct, showing that sedentary behaviour was not impacted by high levels of aerobic training.

Unprompted vigorous physical activity is associated with higher levels of subsequent sedentary behaviour in participants with low cardiorespiratory fitness: a cross‐sectional study

“…Despite documented increases in VPA and mean accelerometer measured activity (cpm), they observed no significant difference in mean SB. However, the participants in the study by Swartz et al (2016) were healthy adult marathon runners with substantially lower BMI and age compared to the participants in the present study, which may contribute to the discrepancy with our results.…”

Off-Training Levels of Physical Activity and Sedentary Behavior in Young Athletes: Preliminary Results during a Typical Week

“…The Sedentary group showed the highest mean sedentary PA per hour of waking time, while the Balanced group presented the highest mean MVPA per hour of waking time, and the Hazardous group had the lowest sedentary PA and MVPA. Both Sedentary and Balanced, however, achieve the WHO daily recommended levels of MVPA, considering the mean wear time for the sample of this study was 11 h. Previous studies have reported that PA and SED are distinct domains not only for those who do not meet the recommended guideline levels, but also for those who do, including young people [39] and athletes [10,40].…”

Sedentary behaviour, physical activity and cardiometabolic health in highly trained athletes: A systematic review and meta‐analysis

“…All studies were written in English and performed in eight different countries predominantly originating from Portugal (n=3). The studies included athletes from various disciplines including cross-country skiers (Alméras et al, 1991), university students with 9 different sports [cycling, hockey, kayaking, rugby, netball, athletics, water sports and rowing] (Clemente, Nikolaidis, Martins, & Mendes, 2016;Driller, Dixon, & Clark, 2017), triathlon (Drenowatz, Eisenmann, Pivarnik, Pfeiffer, & Carlson, 2013), cycling (Drenowatz et al, 2013;Pollock et al, 2018), running (Drenowatz et al, 2013;Exel, Mateus, Abrantes, Leite, & Sampaio, 2019;Rantalainen, Pesola, Quittner, Ridgers, & Belavy, 2018;Swartz, Miller, Cho, Welch, & Strath, 2017;Whitfield, Pettee Gabriel, & Kohl, 2014), football (Exel et al, 2019;Weiler, Aggio, Hamer, Taylor, & Kumar, 2015), elite athletes from different disciplines [long-distance running, road cycling, triathlon, judo, taekwondo, swimming, sailing, tennis, handball, track and field athletics and pentathlon] (Júdice, Silva, Magalhães, Matias, & Sardinha, 2014) and rowing . McCracken et al only reported different sport categories which consisted of snow/ice, water, team, skill, racquet, multi, endurance, lifting, urban and others (McCracken & Dogra, 2018).…”
