Summary
Wearable activity trackers did not increase physical activity (PA) in college students within a credit-based program. The intervention group showed no change in moderate- to vigorous-intensity PA, unlike the control group.
Area of Science:
- Exercise Science
- Behavioral Science
- Higher Education Pedagogy
Background:
- College students often struggle to maintain physical activity (PA) levels.
- Credit-based physical activity instructional programs (PAIP) aim to promote PA in this demographic.
- Wearable activity trackers are increasingly explored as tools for behavior change.
Purpose of the Study:
- To investigate the effectiveness of wearable activity trackers in a PAIP for college students.
- To determine if integrating activity trackers influences moderate- to vigorous-intensity physical activity (MVPA) levels.
- To assess changes in overall PA and sedentary behavior over an academic semester.
Main Methods:
- Randomized controlled trial involving 14 PAIP courses at a large public university.
- Intervention group (n=101) received Misfit Flash activity trackers; control group (n=86) did not.
- Objective PA assessments conducted at baseline, mid-, and end-of-semester over 15 weeks.
Main Results:
- The control group experienced a significant decrease in MVPA minutes from baseline to end-of-semester.
- The intervention group demonstrated no significant changes in MVPA minutes throughout the study period.
- The intervention group paradoxically increased sedentary time and decreased light-intensity PA.
Conclusions:
- Utilizing wearable activity trackers as a primary behavior change strategy in this PAIP setting yielded null effects on promoting PA.
- The integration of wearable technology alone may not be sufficient to enhance physical activity in college students within an instructional program.
- Further research is needed to explore more comprehensive strategies for leveraging technology to increase PA in higher education.

25.6K
The organization of prokaryotic genes in their genome is notably different from that of eukaryotes. Prokaryotic genes are organized, such that the genes for proteins involved in the same biochemical process or function are located together in groups. This group of genes, along with their regulatory elements, are collectively known as an operon. The functional genes in an operon are transcribed together to give a single strand of mRNA known as polycistronic mRNA.

8.7K
Gene transcription is regulated by the synergistic action of several proteins that form a complex at a gene regulatory site. This is observed in eukaryotes, where the regulation of gene expression is a complex process. Regulatory proteins in eukaryotes can broadly be classified into two types – regulators that bind directly to specific DNA sequences and co-regulators that associate with regulatory proteins but cannot directly bind to the DNA. These co-regulators are further divided into...

02:42Eukaryotic Transcription Activators
12.9K
Transcription activators are proteins that promote the transcription of genes from DNA to RNA. In most cases, these proteins contain two separate domains ‒ a domain that binds to DNA and a domain for activating transcription; however, in some cases, a single domain is responsible for both binding and activation of transcription, as seen in the glucocorticoid receptor and MyoD.
The binding domains are capable of recognizing and interacting with regulatory sequences on the DNA. These...

23.2K
Aminoacyl-tRNA synthetases are present in both eukaryotes and bacteria. Though eukaryotes have 20 different aminoacyl-tRNA synthetases to couple to 20 amino acids, many bacteria do not have genes for all of these aminoacyl-tRNA synthetases. Despite this, they still use all 20 amino acids to synthesize their proteins. For instance, some bacteria do not have the gene encoding the enzyme that couples glutamine with its partner tRNA. In these organisms, one enzyme adds glutamic acid to all of the...

01:26Activation Energy
87.2K
Activation energy is the minimum amount of energy necessary for a chemical reaction to move forward. The higher the activation energy, the slower the rate of the reaction. However, adding heat to the reaction will increase the rate, since it causes molecules to move faster and increase the likelihood that molecules will collide. The collision and breaking of bonds represents the uphill phase of a reaction and generates the transition state. The transition state is an unstable high-energy state...

01:23Physical Methods for Controlling Microbial Growth: Temperature
1.2K
Heat is a widely used method to control microbial growth by targeting and denaturing cellular proteins, thereby killing or inactivating microbes. This method's effectiveness is quantified using parameters such as the thermal death point (TDP), thermal death time (TDT), and decimal reduction time (D value). TDP represents the lowest temperature at which all microorganisms in a liquid suspension are eliminated within 10 minutes, whereas TDT is the time necessary to achieve sterilization at a...
