Profile Leveling and Cross Sections01:26

Profile Leveling and Cross Sections

1.7K
Profile leveling and cross-sections are surveying methods used to determine and document terrain elevations for infrastructure projects such as highways, railroads, canals, and pipelines. These methods provide data for earthwork planning and alignment of proposed routes.  Profile leveling involves measuring elevations along a fixed line to create a vertical terrain profile. A surveyor sets up a leveling instrument at the benchmark (BM) and records a backsight (BS) to determine the...

Crossing Over01:34

Crossing Over

172.2K
Unlike mitosis, meiosis aims for genetic diversity in its creation of haploid gametes. Dividing germ cells first begin this process in prophase I, where each chromosome—replicated in S phase—is now composed of two sister chromatids (identical copies) joined centrally.
The homologous pairs of sister chromosomes—one from the maternal and one from the paternal genome—then begin to align alongside each other lengthwise, matching corresponding DNA positions in a process...

Crossing Over

6.6K
Crossing over is the exchange of genetic information between homologous chromosomes during prophase I of meiosis I. Genetic recombination gives rise to allelic diversity in the newly formed daughter cells. In humans, crossing over produces genetically distinct haploid egg and sperm cells that undergo fertilization to produce unique offspring. Before cell division starts, the germ cell’s chromosome(s) undergo duplication in the S phase of the cell cycle. As the cells enter prophase I,...

Cross-Sectional Research01:50

Cross-Sectional Research

12.7K
In cross-sectional research, a researcher compares multiple segments of the population at the same time. If they were interested in people's dietary habits, the researcher might directly compare different groups of people by age. Instead of following a group of people for 20 years to see how their dietary habits changed from decade to decade, the researcher would study a group of 20-year-old individuals and compare them to a group of 30-year-old individuals and a group of 40-year-old...

Alterations in Respiration II01:30

Alterations in Respiration II

1.9K
There are numerous types of normal and abnormal respiration. Based on ventilatory movements, breathing patterns are classified as regular, deep, or shallow. Examples include Biot's breathing, Cheyne-Stokes respiration, Kussmaul's breathing, hyperventilation, and hypoventilation. Each pattern is clinically significant and aids in evaluating patients.
In Biot's breathing, the respiratory rate and depth are irregular, alternating between periods of deep gasping and apnea. Common causes...

Summary

A school-based cross-training program did not significantly alter body mass index (BMI), attitudes toward physical activity (ATPA), or physical activity (PA) levels in 4th and 5th graders. However, the program was safe and did not negatively impact PA, suggesting potential benefits.

Area of Science:

  • Pediatric Exercise Science
  • School Health Programs
  • Physical Education

Background:

  • Childhood obesity is a growing concern, necessitating effective school-based interventions.
  • Physical activity is crucial for children's health and development.
  • Understanding the impact of structured physical activity programs on children's health metrics is vital.

Purpose of the Study:

  • To investigate the effects of a school-based cross-training program on body mass index (BMI), attitudes toward physical activity (ATPA), and physical activity (PA) levels.
  • To assess the safety and impact of a 10-week cross-training intervention on 4th and 5th-grade students.
  • To determine if cross-training influences children's engagement with and attitudes towards physical activity.

Main Methods:

  • A 10-week school-based cross-training program involving resistance training, calisthenics, and stretching was implemented twice weekly.
  • 118 children in 4th and 5th grades were assigned to either a control group (n=60) or an experimental group (n=58).
  • Pre- and post-intervention measurements included height, mass (for BMI calculation), ATPA, and PA levels assessed via questionnaires.

Main Results:

  • No significant differences in BMI, ATPA, or PA were observed between the control and experimental groups post-intervention.
  • Both groups showed significant increases in BMI and PA levels over the study period.
  • While attitudes toward health and fitness decreased in the experimental group, the cross-training program did not detract from overall PA levels.

Conclusions:

  • School-based cross-training programs appear safe and potentially enjoyable for children's physical activity participation.
  • Increases in BMI and PA were likely influenced by natural growth and seasonal changes, respectively.
  • Shorter cross-training programs incorporating varied resistance training protocols may be more effective, warranting further investigation.
