Abstract
Objective: Repetition of physical activity (PA) contributes to the formation of PA habit. However, daily repetitions of PA of varied intensities might differ in their impact on PA habits. This study investigated the effect of daily variability in PA on various facets of PA habits: lack of intention (LOI), lack of control (LOC) and efficiency of PA.
Methods: Daily time spent on light-, moderate- and vigorous-intensity of PA (LPA, MPA and VPA) were assessed for 14 consecutive days among 182 college students. PA habits were measured afterwards.
Results: The results of mixed-effects random location-scale model showed that LOI was negatively predicted by variability in daily LPA; and that LOC was negatively predicted by daily variability in LPA and MPA.
Conclusion: These findings suggest interventions of PA habit formation should focus on different facets of PA habits and consider the impact of daily repetition of PA of varied intensities.
期刊介绍：
Psychology & Health promotes the study and application of psychological approaches to health and illness. The contents include work on psychological aspects of physical illness, treatment processes and recovery; psychosocial factors in the aetiology of physical illnesses; health attitudes and behaviour, including prevention; the individual-health care system interface particularly communication and psychologically-based interventions. The journal publishes original research, and accepts not only papers describing rigorous empirical work, including meta-analyses, but also those outlining new psychological approaches and interventions in health-related fields.
