Enhancing Performance and Health Outcomes with Optimal Exercise and Nutrition Programming

Exercise and nutrition, when used as a mode to improve health outcomes is well-researched and accepted by researchers and clinicians, alike. Numerous health organizations have developed general recommendations such as physical activity and exercise to inform the public how to improve health outcomes. More often than not, these guidelines are vague and do not suggest how to achieve optimal health via exercise and nutrition. These guidelines also fail to consider physiological and psychological variability for patients and individuals aiming to follow such guidelines. For example, current recommendations include exercise intensities based on low, moderate, and vigorous activity and many people may not understand the physiological cost of such exercise intensities. Presently, accessible consumer-grade technology allows for accurate measurements of relative heart rate, exercise time, distance, and estimated caloric expenditure which is presumed easy for any person to understand. Therefore, creating guidelines that target specific and measurable variables, such as relative heart rate may be more advantageous for individualized health optimization.

Physical Activity and Exercise for Optimal Disease Prevention: Clinical Evidence

Previous physical activity guidelines from health organizations provide general physical activity and exercise intensity and duration recommendations. These guidelines have experienced very little change over the last two decades, despite significant changes in technology, more specifically wearable technology. The guidelines typical refer to exercise intensity as low, moderate and vigorous intensity based on a metabolic equivalent scale (MET) or a subjective scale. With wearable technology being accessible, affordable, reliable, and accurate, more attention should be given address recommendations that are multifaceted and specific. Most wearable technology can easily track sleep, steps, calories, hear rate, and exercise time within certain heart rate training zones. Research has shown that monitoring exercise and physical activity with wearable technology can improve health outcomes3.

Medical Brigades to El Salvador and Honduras: Travel imaginaries and volunteer tourist recruitment

In this paper, I explore travel imaginaries in the recruitment of participants to short-term medical brigades in El Salvador and Honduras. I look in particular at how trip leaders and organization web sites frame the volunteer tourist experience, drawing on familiar, shared imaginaries of poor, backward international settings, and related performative interventions that echo white colonial relationships. Recruitment messaging offers little specific or informed sense of place, ignoring the national histories and socio-economic circumstances of the receiving countries. As a consequence, the health profiles and capacities of El Salvador and Honduras are finally obscured in favor of the valorized performance of visitors and externally-driven protocols and care. The efforts of some brigade sponsors and related organizations to improve health-care delivery to local communities, in particular fundraising among brigade participants and other donors, would seem to separate the link between travel and volunteerism. They continue, however, to reinforce broadly-held imaginaries of international poverty and economic backwardness and related rescue by the Global North. A more realistic understanding of Honduran and Salvadoran economies and politics remains elusive and requires a reorientation of voluntary engagement.

The effectiveness of supervision strategies to improve health care provider practices in low- and middle-income countries: secondary analysis of a systematic review

Background Although supervision is a ubiquitous approach to support health programs and improve health care provider (HCP) performance in low- and middle-income countries (LMICs), quantitative evidence of its effects is unclear. The objectives of this study are to describe the effect of supervision strategies on HCP practices in LMICs and to identify attributes associated with greater effectiveness of routine supervision. Methods We performed a secondary analysis of data on HCP practice outcomes (e.g., percentage of patients correctly treated) from a systematic review on improving HCP performance. The review included controlled trials and interrupted time series studies. We described distributions of effect sizes (defined as percentage-point [%-point] changes) for each supervision strategy. To identify attributes associated with supervision effectiveness, we performed random-effects linear regression modeling and examined studies that directly compared different approaches of routine supervision. Results We analyzed data from 81 studies from 36 countries. For professional HCPs, such as nurses and physicians, primarily working at health facilities, routine supervision (median improvement when compared to controls: 10.7%-points; IQR: 9.9, 27.9) had similar effects on HCP practices as audit with feedback (median improvement: 10.1%-points; IQR: 6.2, 23.7). Two attributes were associated with greater mean effectiveness of routine supervision (p < 0.10): supervisors received supervision (by 8.8–11.5%-points), and supervisors participated in problem-solving with HCPs (by 14.2–20.8%-points). Training for supervisors and use of a checklist during supervision visits were not associated with effectiveness. The effects of supervision frequency (i.e., number of visits per year) and dose (i.e., the number of supervision visits during a study) were unclear. For lay HCPs, the effect of routine supervision was difficult to characterize because few studies existed, and effectiveness in those studies varied considerably. Evidence quality for all findings was low primarily because many studies had a high risk of bias. Conclusions Although evidence is limited, to promote more effective supervision, our study supports supervising supervisors and having supervisors engage in problem-solving with HCPs. Supervision’s integral role in health systems in LMICs justifies a more deliberate research agenda to identify how to deliver supervision to optimize its effect on HCP practices.

Can Popular High-Intensity Interval Training (HIIT) Models Lead to Impossible Training Sessions?

High-Intensity Interval Training (HIIT) is a time-efficient training method suggested to improve health and fitness for the clinical population, healthy subjects, and athletes. Many parameters can impact the difficulty of HIIT sessions. This study aims to highlight and explain, through logical deductions, some limitations of the Skiba and Coggan models, widely used to prescribe HIIT sessions in cycling. We simulated 6198 different HIIT training sessions leading to exhaustion, according to the Skiba and Coggan-Modified (modification of the Coggan model with the introduction of an exhaustion criterion) models, for three fictitious athlete profiles (Time-Trialist, All-Rounder, Sprinter). The simulation revealed impossible sessions (i.e., requiring athletes to surpass their maximal power output over the exercise interval duration), characterized by a few short exercise intervals, performed in the severe and extreme intensity domains, alternating with long recovery bouts. The fraction of impossible sessions depends on the athlete profile and ranges between 4.4 and 22.9% for the Skiba model and 0.6 and 3.2% for the Coggan-Modified model. For practitioners using these HIIT models, this study highlights the importance of understanding these models’ inherent limitations and mathematical assumptions to draw adequate conclusions from their use to prescribe HIIT sessions.

Production of Bovine Colostrum for Human Consumption to Improve Health

Colostrum contains all essential nutrients for the neonate during the first days of life, with impacts that continue far beyond these first days. Bovine colostrum has been used for human consumption due to the high concentrations of bioactive proteins, vitamins, minerals, growth factors, as well as free and conjugated oligosaccharides. Processes involved in the preparation of bovine colostrum for human consumption play a pivotal role in preserving and maintaining the activity of the bioactive molecules. As bovine colostrum is a multifunctional food that offers a myriad of benefits for human health, assessing the main processes used in preparing it with both advantages and disadvantages is a crucial point to discuss. We discuss major processes effects for colostrum production on the nutritional value, some advanced technologies to preserve processed bovine colostrum and the end-product forms consumed by humans whether as dairy products or dietary supplements.

Happy Elderly in the Pandemic Period with Elderly Gymnastics and Counseling Methods

Elderly is an advanced stage of the life process decreasing the body's ability to adapt to the environment. Degenerative disease is a disease that occurs due to decreased organ function, including hypertension, rhematoid arthritis, stroke, diabetes mellitus. Various strategies are pursued to improve health status and reduce morbidity in the elderly. One of them is through physical activity that is in accordance with the physical condition of the elderly and is carried out regularly. In addition, increasing knowledge through counseling which aims to help the elderly make decisions and determine a healthy lifestyle. The purpose of this activity is to improve the quality of life of the elderly. The method used is by doing elderly exercise with pre and post blood pressure checks so that it can be seen the significance of the benefits of exercise. In addition, counseling was carried out using lecture, discussion and question and answer methods. The target audience for this community service program is the elderly (elderly) in the Poskesdes Village of Benteng who are physically categorized as doing sports / physical activity for the elderly. The results of this activity show that the effectiveness of elderly gymnastics has an effect on reducing blood pressure. And from counseling, the results of the evaluation show that the elderly understand and understand the concept of healthy elderly people related to the pandemic.

Pregnant Women’s Exposure to Household Air Pollution in Rural Bangladesh: A Feasibility Study for Poriborton: The CHANge Trial

The use of liquefied petroleum gas (LPG) for cooking is a strategy to reduce household air pollution (HAP) exposure and improve health. We conducted this feasibility study to evaluate personal exposure measurement methods to representatively assess reductions in HAP exposure. We enrolled 30 pregnant women to wear a MicroPEM for 24 h to assess their HAP exposure when cooking with a traditional stove (baseline) and with an LPG stove (intervention). The women wore the MicroPEM an average of 77% and 69% of the time during the baseline and intervention phases, respectively. Mean gravimetric PM2.5 mass and black carbon concentrations were comparable during baseline and intervention. Temporal analysis of the MicroPEM nephelometer data identified high PM2.5 concentrations in the afternoon, late evening, and overnight during the intervention phase. Likely seasonal sources present during the intervention phase were emissions from brick kiln and rice parboiling facilities, and evening kerosene lamp and mosquito coil use. Mean background adjusted PM2.5 concentrations during cooking were lower during intervention at 71 μg/m3, versus 105 μg/m3 during baseline. Representative real-time personal PM2.5 concentration measurements supplemented with ambient PM2.5 measures and surveys will be a valuable tool to disentangle external sources of PM2.5, other indoor HAP sources, and fuel-sparing behaviors when assessing the HAP reduction due to intervention with LPG stoves.
