Special Issue Information

Dear Colleagues,

The current COVID-19 pandemic has highlighted the need for a healthy lifestyle as various pre-existing conditions, including cardiovascular disease, obesity, and several others, appear to result in an increased risk of negative outcomes. Regular exercise and a proper diet are two key facilitators of an overall healthy lifestyle that have regularly demonstrated improved functioning of almost every system within the body.

The benefits observed in response to regular exercise on markers of cardiorespiratory and muscular fitness are undeniable. Less known, however, are the benefits associated with other systems within the body, including the immune system. High levels of regular exercise have previously been portrayed as a “double-edged sword” with increasing exercise volume and intensity potentially suppressing immune function. Recently, this concept has been challenged due to the large number of extranous variables that influence immune function, including stress, sleep, and, most notably, nutrition. Proper balanced nutrition, particularly with regard to adequate vitamin, mineral, and protein intake, enhances resistance against infection.

Therefore, this Special Issue seeks manuscripts that address the role of exercise and nutrition, both individually or in conjunction, in enhancing the function of various systems throughout the body. We encourage papers with an emphasis on cross-disciplinary collaboration to enhance our understanding and the application of healthy lifestyles. Our goal is for this Special Issue to encourage inquiry into the additive and synergistic role of nutrition and exercise in the optimization of human health and exercise performance.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. International Journal of Environmental Research and Public Health is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2500 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Effects of Isomaltulose Ingestion on Thermoregulatory Responses during Exercise in a Hot Environment
by Junto Otsuka, Yumi Okamoto, Naoto Fujii, Yasuaki Enoki, Daisuke Maejima, Takeshi Nishiyasu and Tatsuro Amano

Abstract
Isomaltulose is a low glycemic and insulinemic carbohydrate available as a constituent of sports drinks. However, it remains unclear whether thermoregulatory responses (sweating and cutaneous vasodilation) after isomaltulose drink ingestion differ from those of sucrose and water during exercise in a hot environment.

Isomaltulose is a low glycemic and insulinemic carbohydrate available as a constituent of sports drinks. However, it remains unclear whether thermoregulatory responses (sweating and cutaneous vasodilation) after isomaltulose drink ingestion differ from those of sucrose and water during exercise in a hot environment. Ten young healthy males consumed 10% sucrose, 10% isomaltulose, or water drinks. Thirty-five minutes after ingestion, they cycled for fifteen minutes at 75% peak oxygen uptake in a hot environment (30 °C, 40% relative humidity). Sucrose ingestion induced greater blood glucose concentration and insulin secretion at the pre-exercise state, compared with isomaltulose and/or water trials, with no differences during exercise in blood glucose. Change in plasma volume did not differ between the three trials throughout the experiment, but both sucrose and isomaltulose ingestions similarly increased plasma osmolality, as compared with water (main beverage effect, p = 0.040)—a key response that potentially delays the onset of heat loss responses. However, core temperature thresholds and slopes for heat loss responses were not different between the trials during exercise. These results suggest that ingestion of isomaltulose beverages induces low glycemic and insulinemic states before exercise but does not alter thermoregulatory responses during exercise in a hot environment, compared with sucrose or water.

This study analyzed the correlation between elementary school students’ body composition, physical activity, physical fitness, movement ability, and academic achievement. Movements ranged from simple actions to complex movements requiring executive functioning. In total, 110 fourth graders (60 boys, 50 girls) participated in this experiment. Body composition (BMI, % of body fat), physical activity (pedometer), physical fitness (muscular strength, endurance, power, flexibility, and VO2max), and complex movement abilities (Illinois Agility test, soda pop hand test, and soda pop foot test) were measured. Regression modeling of body composition and fitness/activity variables was able to account for 30.5% of the variation of total academic scores in females, but only 4.3% in males. No individual tests were reliably correlated with multiple academic outcomes in males. However, hand and foot soda pop times, as well as Illinois Agility scores, were repeatedly correlated with academic outcomes in females, each correlating with 4 of the 6 academic scores. Body composition and physical activity level did not correlate with academic achievement, and simple physical fitness showed a low correlation with academic achievement in both boys and girls. On the other hand, complex, cognitively demanding movements such as the Illinois Agility, soda pop hand, and soda pop foot tests had consistent correlations with academic achievement in girls, but not in boys.
