Youth Physical Activity and Enjoyment during Semi-Structured versus Unstructured School Recess

The obesity epidemic is affecting children of all ages including young children and adolescents and when obesity occurs during adolescence, it tends to persist into adulthood. The prevalence of physical inactivity among school-aged children has contributed to the substantial rise in overweight and obesity.

Physical activity throughout the school day may help reduce the risk of childhood obesity. Recess refers to a break from doing something, like work or school. Daily recess has been shown to play a significant role in increasing PA as well as increasing learning, productivity, concentration, and social development. Also, research has found that structured recess can be a novel approach to provide new PA choices at recess. In this study, the authors aimed to compare the physical activity and enjoyment of urban school children during traditional unstructured recess and semi-structured recess.

The sample for this study consisted of 165 elementary school children (n = 89 males) in the Southwestern United States. Students were recruited via PE class while at school. They wore a NL-1000 piezoelectric accelerometer during their 15-minute lunch recess and participated in both their traditional unstructured (no structure and no equipment) recess and semi-structured (organized games and equipment) recess. An enjoyment scale was completed after both types of recess formats. Accelerometer data were examined to determine the mean and standard deviation for step counts and minutes spent in moderate to vigorous physical activity (MVPA) during unstructured and semi-structured recess. Questionnaire data was used to determine PA enjoyment during unstructured and semi-structured recess. Analyses were conducted using IBM Statistics SPSS 21.0 software.

The results revealed that during unstructured recess, children accumulated 1028 ± 356 steps and 4.59 ± 2.2 minutes of MVPA compared to 1156 ± 434 steps and 5.44 ± 2.76 minutes of MVPA during semi-structured recess. Paired sample t-tests revealed that children took significantly more steps (t = −4.98; p < 0.001) and MVPA (t = −5.940; p < 0.001) during semi-structured recess. No significant differences were found for enjoyment (p = 0.847) between recesses.

In conclusion, this study suggests that semi-structured recess represents a feasible and viable intervention for schools to implement for promoting PA. The findings indicate that a semi-structured recess environment may create more PA among children while at school. Implementing semi-structured recess is an inexpensive, simple way to increase children’s PA for schools during lunch recess so they can accumulate more minutes of daily recommended MVPA without causing a negative effect on enjoyment. Further research is necessary to determine the effectiveness of semi-structured recess on PA, MVPA, and recess enjoyment on children.

Incorporation of High-Altitude Balloon Experiment in High School Science Classrooms

High-altitude balloon is a balloon, filled usually with helium or hydrogen that ascends into an area called “near space” or stratosphere. The most common type of high-altitude balloons are weather balloons. Other purposes include use as a platform for experiments in the upper atmosphere. Modern balloons generally contain electronic equipment such as radio transmitters, cameras, or satellite navigation systems, such as GPS receivers. The mission of the High-Altitude Balloon Experiment (HABE) is to acquire supporting data, validate enabling technologies, and resolve critical acquisition, tracking, and pointing (ATP) and fire control issues in support of future space-based precision pointing experiments. The use of high-altitude balloons offers a relatively low-cost, low-vibration test platform, a recoverable and reusable payload, worldwide launch capability, and a 'near- space' emulation of the future space systems operational scenarios. More recently, several university...

The Influence of Heated Soil in Crop of “Tamaris” Tomato Plants on the Biological Activity of the Rhizosphere Soil

Tomato is a plant with high heat requirements and sensitive to cold weather and frost. The optimum temperature for the growth of tomato plants is between 21˚C and 27˚C during the day and between 17˚C and 21˚C at night. The soil temperature is also very important for plant growth. The optimum soil temperature for tomato cultivation should be within the range 15˚C - 18˚C. Besides, the proper development of the root system depends on the optimal temperature of the soil. A temperature below 14˚C reduces and inhibits the growth of the root system and encourages the development of fungal and bacterial diseases. In this study, the authors aimed to evaluate the effect of heated soil on the population of bacteria, fungi and nematodes inhabiting the soil of tomato cultivar “Tamaris” growing in peat and coconut substrates. The experiment was carried out in 12 treatments and in 3 replications (one slab was one replication). The soils were tested in two different types of containers: cylinders...

Effect of Proline Pretreatment on Grapevine Shoot-Tip Response to a Droplet-Vitrification Protocol

Proline is an α-amino acid that is used in the biosynthesis of proteins. Some studies have shown that proline has been accumulated in plants in response to biotic and abiotic stresses. Exogenous proline has thus been used for improving some plant cryopreservation protocols. Further enhancement of cryopreservation efficiency for  in vitro  grapevines could be expected if stresses linked to cryopreservation procedures could be reduced. In this study, the authors studied the possible beneficial effect of proline in grapevine cryopreservation. Single-node explants from  in vitro  grown grapevine plantlets ( Vitis vinifera  L. cv Portan) were cultured on shooting media (half-strength MS + 1 μM BAP) containing no proline (control) or 50, 500, or 2000 μM filter-sterilized L-proline. Shoot tips excised from these microshoots were subjected to a PVS2-based droplet-vitrification procedure. Control and rewarmed explants were grown on a recovery medium containing ...
