The current world population of about 6.8 billion people will have grown in 2050 to an estimated 9 billion people. To provide everybody of food in the future, it is important to answer the question how this can be acheived. Lupin is a good source of vegetable protein, and may also be regionally grown. Lupin protein also may have a health benefit.
The capacity to utilize ingested protein for optimal support of protein synthesis and lean body mass is described within the paradigm of anabolic competence. Protein synthesis can be stimulated by physical exercise, however, it is not known if physical exercise affects post-exercise protein oxidation. Characterization of the driving forces behind protein oxidation, such as exercise, can contribute to improved understanding of whole body protein metabolism. The purpose of this study is to determine the effect of two levels of aerobic exercise intensity on immediate post-exercise exogenous protein oxidation. Sixteen healthy males with a mean (SD) age of 24 (4) years participated. The subjects' VO2-max was estimated with the Åstrand cycling test. Habitual dietary intake was assessed with a three-day food diary. Exogenous protein oxidation was measured by isotope ratio mass spectrometry. These measurements were initiated after the ingestion of a 30 g 13C-milk protein test drink that was followed by 330 minutes breath sample collection. On three different days with at least one week in between, exogenous protein oxidation was measured: 1) during rest, 2) after 15 minutes of aerobic exercise at 30% of VO2-max (moderate intensity), and 3) after 15 minutes of aerobic exercise at 60% of VO2-max (vigorous intensity). After vigorous intensity aerobic exercise, 31.8%±8.0 of the 30 g 13C-milk protein was oxidized compared to 26.2%±7.1 during resting condition (p = 0.012), and 25.4%±7.6 after moderate intensity aerobic exercise compared to resting (p = 0.711). In conclusion, exogenous protein oxidation is increased after vigorous intensity aerobic exercise which could be the result of an increased protein turnover rate.
De Simpel Fit! interventie is ontwikkeld in 2009 door de GGD Noord- en Oost-Gelderland (GGD NOG) voor de Turkse doelgroep en veelvuldig uitgevoerd in en rondom Gelderland. Sinds 2016, wordt de interventie ook uitgevoerd in Amsterdam door de Stichting voor Interculturele Participatie en Integratie (Sipi). Ook is de interventie uitgebreid met een Marokkaanse variant. Na uitbreiding van de interventie, is vanuit de uitvoerend professional de vraag gekomen om onderzoek te doen naar de effecten van de interventie. Voorgaande pogingen om dit te doen bleken moeilijkheden met zich mee te brengen. Zo bleek onder andere, uit oriënterende gesprekken met de ontwikkelaars en uitvoerders, dat het meetinstrument te talig was. Daarom is het lectoraat Voeding en Beweging van de Hogeschool van Amsterdam (HvA) nu gevraagd om een uitgebreide effectevaluatie te verrichten met een tool die beter aansluit bij de doelgroepen.
