Background: Cardiorespiratory endurance is one of the main factors for exercising. Cardiorespiratory endurance can be known by measuring ṼO2max. Fruits and vegetables intake can give beneficial impact for endurance athletes. Fruits and vegetables are thought to affect endurance by delaying fatigue caused by nutrients contained such as carbohydrates, vitamins, minerals, and phytochemicals. Previous studies stated that fruit sources of carbohydrates are known to improve ṼO2maks. Beta carotene and vitamin C have been proven to increase endurance. Carrots and oranges are high in beta carotene and vitamin C. Carrot and orange also contain a high level of potassium. Potassium is one of the main mineral which is needed for endurance exercise and it also has the potential to help carbohydrates metabolism in converting glucose to glycogen which later saved by the liver as an energy source. The effect of the combination of beta carotene, vitamin C and potassium on carrot and orange juice on cardiorespiratory endurance in athletes requires further analysis. Indonesian Journal of Nutrition and Dietetics Vol. 7, No. 1, 2019: 23-30 Available online at: http://ejo rnal.almaat .ac.id/index.php/IJND DOI : http://dx.doi.org/10.21927/ijnd.2019.7(1).23-30 24 Yeri A. Putri, Eni Yusniati, Diana Nurrohima, Herviana, Desty Ervira Puspaningtyas,Yuni Afriani, Vol 7 No. 1, 2019: 23-30 Carrots and oranges are natural sources of carbohydrates and electrolytes. Carrots are a type of vegetable that is high in carbohydrates, potassium, and antioxidants. The kind of simple carbohydrates in citrus fruits are fructose, glucose, and sucrose which can provide energy source quickly (9). The high content of beta-carotene from carrots and high vitamin C content in orange have the potential as antioxidants to help oxidative inhibition that can occur during endurance exercise thus preventing fatigue and improving cardiorespiratory endurance. Potassium in carrots and oranges works for fluid balance of the body and is responsible for delivering nerve impulses and muscle contractions. A study states thatincreased activity of Na +, K +, and ATPase during exercise can stabilize the concentration of sodium and potassium in the membrane so that it can prevent fatigue (10). Potassium also influences the uptake and transport of glucose in the small intestine for it to can be used as an energy source (11). UKM bola UAD (Universitas Ahmad Dahlan) has a training schedule for four times a week with 90 minutes duration in each timeline. The endurance training program carried out in the form of jogging, zig-zag running, hurdles, and twisting which done for 40 minutes every three times a week. On the average, the Members of UKM have an excellent nutritional status which is around 77.27% of the population. According to the last ṼO2max records which were measured by using bleep test, it shows the mean of ṼO2max that had been accomplished by the population only around 43.74 ml/kg/min which Objectives: The purpose of this study was to assess the effect of carrot-orange juice on ṼO2max in soccer players. Methods: This study was a quasi-experimental with pre-post test without control group design. There were nine soccer players from Universitas Ahmad Dahlan Yogyakarta that were taken by using purposive sampling which is match with criteria. The subject had been given 250 ml of carrot-orange juice for 13 days. ṼO2max was measured by using a yoyo intermittent recovery test I. All data were analyzed by paired T-test. Results: The mean of ṼO2max in soccer players before consuming carrot-orange juice is 44.02 ± 2.66 ml /kg /min and after consuming carrot-orange juice is 45.88 ± 3.11 66 ml /kg /min. There was significant ṼO2max difference after carrot-orange (p= 0.003). Conclusion: Consumption of carrot-orange juice for 13 days effectively increase ṼO2max level of soccer players.

Several species of Amaranthus have a long history of consumption as a vegetable/cereal and usage in traditional medicine. A great miscellany of healthful compounds such as fatty acids, steroids, lipids, amino acids, vitamins, minerals, and bioactives, including alkaloids, flavonoids, glycosides, phenolic acids, saponins, terpenoids, tannins, and carotenoids have been found in Amaranthus seeds, roots, stem, and leaves, depending on the plant maturity stage, cultivar type, and geographical location. Preclinical studies have shown that the extracts and bioactive constituents of Amaranthus spp. confer several biological activities, including antioxidant, immunomodulatory, hepatoprotective, gastroprotective, cardioprotective, hypolipidemic, anticancerous, antidiabetic, and antimicrobial, which has ignited the interest of researchers in this modest vegetable all over the world. Although some potential health benefit-based mechanistic studies are available, a need exists to investigate in-depth the roles of these specific bioactives sourced from Amaranthus for their potential use in disease treatment and daily diet for a holistic well-being. Lately, investigators have also started to examine the use of amaranth leaves and seeds for the development of fortified food products whose consumption can lead to beneficial biological effects. Conversely, the plant is still missing recognition in the pharmaceutical and commercial food packaging sectors. The present chapter provides a detailed exploration of current research on the bioactive-constituents of amaranth, its use in traditional medicine, clinical studies validating traditional claims and recent trends in usage of this underutilized vegetable as a nutraceutical and functional food. This insight will be beneficial for encouraging exhaustive research which will promote effective utilization of amaranth.

Intro COVID-19 vaccines are safe and effective at reducing risk of severe COVID-19 among pregnant women, a group at higher risk of severe disease. However, vaccine uptake has been slow among people in Zambia. We sought to describe vaccine uptake among pregnant women in Zambia. Methods We conducted serial cross-sectional surveys among pregnant women attending first antenatal care visits in one rural and two urban districts of Zambia from December 2021 through June 2022. Ten health facilities per district were randomly selected and a convenience sample of 20 women per facility per month were recruited. Consenting participants were administered an electronic questionnaire asking about offers and receipt of COVID-19 vaccines. Findings In total, 3,652 women were recruited from December 2021 to June 2022, and 82.4% had not received a COVID-19 vaccine. Vaccine coverage among participants rose from 10.5% in December 2021 to 28.7% in June 2022 (p<0.01). During the same period, the proportion of women who reported being offered a vaccine rose significantly from 22.4% to 52.5% (p<0.01), with a non-significant increase in the proportion of women who were unvaccinated but willing to accept a vaccine (58.0% to 65.8%, p=0.59). Among 785 women who were unvaccinated and not willing to accept a vaccine, 42.3% were concerned about the safety of vaccination during pregnancy. Conclusion Vaccine coverage among pregnant women in Zambia remains low and safety concerns during pregnancy are high. Door-to-door vaccination campaigns and individual vaccination consultations at all healthcare encounters may increase the number of women being offered a vaccine. Focused safety messaging for pregnant women may help to alleviate fears and increase COVID-19 vaccine uptake.
