Figures 1 and 2 shows the predicted probability for the association between the alter exercising or eating healthily, and the ego exercising or eating healthily.
Figures 7, 8, 9 and 10 show the predicted probability for the interaction between three different potential characteristics of the alter, and the alter exercising or eating healthily.
As can be seen, an alter exercising regularly or eating healthily is associated with an increase in the predicted probability that the ego will also exercise regularly or eat healthily, for both males and females.
First, studies have shown that both gait style and treadmill incline significantly affect the pattern of muscle recruitment, Achilles tendon stretch, and muscle strain in the lower limbs during exercise [ 10– 12], all of which may alter exercise hyperpnea.
Second, it is known that subjects rate uphill walking as being more difficult when compared to horizontal running at similar metabolic rates and that "perception of effort" during exercise can clearly alter exercise hyperpnea [ 13, 14].
Figures 3, 4, 5, and 6 show the predicted probability for the interaction between the strength of the relationship of the ego with the alter, and the alter exercising or eating healthily.
Using ego-alter dyads from the egocentric network data as the unit of analysis, we conduct logistic regressions to investigate the association between ego and alter exercise and eating behaviours.
Finally, season (winter or spring) affects natural light exposure which may cause fluctuations in sleep quality (Hood et al., 2000), impact emotional well-being (Graw, Recker, Sand, Kräuchi, & Wirz-Justice, 2000), and alter exercise routines (Tucker & Gilliland, 2007).
Exclusions included body weight >300 pounds, blood pressure >140/90 mmHg at rest or >190/100 mmHg during exercise, hemoglobin <9 mg/dL, serum creatinine >1.5 mg/dL, smoking, antihypertensive drugs, pregnancy, breastfeeding, ≥3 h of physical activity per week, or plans to alter exercise or diet during the study.
We used a wild rodent, the bush rat Rattus fuscipes, as a model to avoid potential problems from inbreeding and thereby altered exercise responses in laboratory strains.
H3: The association between ego-alter behaviours will be greater with ego-alter homogeneity The first hypothesis, H1, describes that we expect that the ego will be more likely to exercise regularly if the alter also exercises regularly, and that they will be more likely to eat healthily if the alter eats healthily.
