Summary
Public transit use provides significant physical activity (PA) for students, comparable to walking. Promoting active school travel should include public transit as a viable option.
Area of Science:
- Public Health
- Kinesiology
- Transportation Studies
Background:
- Walking and cycling are established sources of physical activity (PA) for students.
- Limited research exists on public transit use for school travel and its role as an active alternative to car use for longer distances.
Purpose of the Study:
- To characterize school trip attributes, including PA levels, across different travel modes.
- To examine the relationship between PA and walking distance during school commutes.
Main Methods:
- 100 school trips from 42 high school students in Vancouver were analyzed using accelerometers and GPS.
- Trip duration, distance, speed, and moderate-to-vigorous PA (MVPA) were calculated.
- Multilevel regression models assessed mode differences and PA associations.
Main Results:
- Students achieved an average of 9.1 minutes of trip-based MVPA, with no significant difference between walking and public transit trips.
- The walking components of transit trips were comparable to dedicated walking trips in distance and duration.
- A dose-response relationship was observed between walking distance and MVPA.
Conclusions:
- Public transit use can substantially contribute to daily physical activity levels for students.
- School policies encouraging active school travel should incorporate public transit as a key component.

Social traps are negative situations where people get caught in a direction or relationship that later proves to be unpleasant, with no easy way to back out of or avoid. The concept was orignally introduced by John Platt who applied psychology to Garrett Hardin's "Tragedy of the Commons", where in New England herd owners could let their cattle graze in the common ground. This situation seems like a good idea, but an individual could have an advantage. If they owned...

2.6K
Active transport is a critical biological process that allows cells to move solutes against an electrochemical gradient. This process requires direct energy input and is characterized by its selectivity, saturability, and susceptibility to competitive inhibition.
Primary active transporters, like Na+, K+ and -ATPase, directly utilize ATP to move ions across the membrane. These transporters play significant roles in various physiological processes. For instance, Na+, K+ and -ATPase maintain...

18.1K
Short-distance transport refers to transport that occurs over a distance of just 2-3 cells, crossing the plasma membrane in the process. Small uncharged molecules, such as oxygen, carbon dioxide, and water, can diffuse across the plasma membrane on their own. In contrast, ions and larger molecules require the assistance of transport proteins due to their charge or size. Transport across membranes also occurs within individual cells, playing a variety of essential roles for the plant as a whole.

1.5K
Carrier-mediated transport is a pivotal process in drug absorption, particularly for lipid-insoluble drugs, and encompasses facilitated diffusion and active transport. Facilitated diffusion allows drugs to move along their concentration gradient without energy expenditure, while active transport utilizes ATP to drive drug movement against this gradient.

Movement joints in buildings are essential design elements that accommodate inevitable motions caused by various factors such as temperature changes, moisture content variations, and structural deflections. These motions, if not considered in design and construction, can lead to unsightly or dangerous damage. Movement joints are incorporated in different forms to manage these stresses and allow materials to move without causing distress.
