Impact of Spirulina maxima Intake and Exercise (SIE) on Metabolic and Fitness Parameters in Sedentary Older Adults with Excessive Body Mass: Study Protocol of a Randomized Controlled Trial.

ABSTRACT: Life expectancy has increased unprecedentedly in recent decades, benefiting the longevity of the world's population. The most frequent pathological conditions presented in this age group include excessive body fat, frailty, and hypercholesterolemia. These pathological characteristics condition general health and autonomy in adults to carry out their usual activities. In this sense, the search for a healthy lifestyle is necessary, consisting in a healthy diet that includes supplementation with nutraceuticals and the daily practice of physical activity. This study protocol aims to evaluate the independent and synergistic effect of 12 weeks of Spirulina maxima intake (5 g/day), with or without an exercise program on metabolic and fitness parameters of 52 sedentary older adults with excessive body mass in a double-blind, randomized, crossover, controlled trial design. The main findings from this trial will provide novel evidence for future interventions designed for the elderly population and the result will be disseminated through peer-reviewed journals and international meetings. ClinicalTrials.gov identification number: NCT04658875 (Effect of Spirulina maxima and Exercise on General Fitness and Blood Lipids in Older Adults).

Project description:Background: The protective properties of high physical fitness levels on health are manifest independently of age, sex, fatness, smoking, alcohol consumption, and other clinical factors. However, women are less active than men, which contributes to low physical fitness and a high risk of CVD. Thus, the objective of this study is to analyze the effect of two exercise interventions on health-related physical fitness in sedentary employed females. Methods: A total of 98 physically inactive adult women were randomly assigned to 3 study groups: the control group (CG) = 31, the endurance training group based on Zumba Fitness® classes (ET; n = 39), and the concurrent training group that had an extra muscle-strengthening workout after the Zumba Fitness® class (CnT; n = 28). Body composition (BMI, waist circumference), motor fitness (one-leg stand test), musculoskeletal fitness (shoulder-neck mobility, handgrip strength test, jump and reach test, and dynamic sit-up test), and cardiorespiratory fitness (2-km test and estimated VO2 max) were assessed with the ALPHA-Fit test battery for adults. Results: Both interventions showed a significant improvement in the majority of health-related fitness and body composition variables/test (waist circumference: ET = -2.275 ± 0.95, p = 0.02, CnT = -2.550 ± 1.13, p = 0.03; one-stand leg test: ET = 13.532 ± 2.65, p < 0.001; CnT = 11.656 ± 2.88, p < 0.001; shoulder-neck mobility: ET = 1.757 ± 0.44, p < 0.001, CnT = 2.123 ± 0.47, p < 0.001; handgrip test: 0.274 ± 0.08, p < 0.001, CnT = 0.352 ± 0.08, p < 0.001; dynamic sit-up: ET = 1.769 ± 0.45, p < 0.001, CnT = -1.836 ± 0.49, p < 0.001; 2-km test time: -1.280 ± 0.25, p < 0.001, CnT = -1.808 ± 0.28, p < 0.001; estimated VO2 max: ET = 1.306 ± 0.13, p < 0.001, CnT = 1.191 ± 0.15, p < 0.001). There were no significant differences after the intervention between the two exercise intervention groups. Conclusions: Exercise interventions based on Zumba fitness® or Zumba fitness® combined with an extra muscle-strengthening workout based on bodyweight training exercises are effective strategies to improve the health-related physical fitness in sedentary women employees.

Project description:Background:While exercise and physical activity are important parts of a healthy life, there is evidence that some individuals exercise to a degree which may jeopardize their health. These individuals may in some cases be exercising to lose weight or compensate binge eating episodes as part of an eating disorder. Others may experience an addiction-like relationship with exercise. Fitness center employees are ideally placed to observe these forms of unhealthy behavior, and are responsible for ensuring that clients do not put themselves at undue risk; however, to date, no study has addressed both eating disorders and excessive exercise. Therefore, the aim of our study is to determine whether these employees report incidences of these issues, and if they believe they can differentiate between them. Methods:One-hundred-and-forty fitness centers in the German-speaking regions of Switzerland were contacted. Of these, 99 employees (60 men, 39 women, Mage =?33.33?years, SD?=?12.02) responded to an online questionnaire. The questionnaire briefly described the two issues of interest (eating disorders and excessive exercise), and then invited respondents to complete a number of questions detailing whether they had experience with these issues, and how they dealt with them. Results:Approximately 75% of the employees had suspected a client of having an eating disorder or exercising excessively, and 65% of these respondents confronted the client at least once. Interestingly, respondents reported clearly that they felt able to differentiate between the two types of disorder. Older respondents were significantly more likely to have suspicions and act on them. However, less than half of the respondents were aware of guidelines addressing this issue, and the majority desired more information about how to identify and address both disorders. Conclusions:Swiss fitness center employees frequently encounter individuals who they suspect of exercising excessively, or suffering from an eating disorder. While they often confront these individuals, they would like more detailed information about how to manage this process. Given that both disorders can potentially lead to severe health consequences, a detailed description of symptoms, management techniques and resources should be a feature in all Swiss fitness center guidelines.

Project description:Regular exercise training is a recognized lifestyle strategy to lower resting blood pressure (BP), but little is known about substrate metabolism in population with high BP. Thus, the purpose of this study was to investigate the effects of 16-weeks of HIIT on body composition, BP, cardiorespiratory fitness by V . O2 max , and substrate utilization during exercise among prehypertensive and hypertensive patients with excessive adiposity. We also aimed to test the potential association between changes in cardiorespiratory fitness, substrate utilization during exercise and BP. Forty-two physically inactive overweight/obese participants participated in 16-weeks of HIIT intervention. The HIIT frequency was three times a week (work ratio 1:2:10, for interval cycling: rest period: repeated times; 80-100% of the maximum heart rate). Groups were distributed based on their baseline BP: HIIT-hypertensive (H-HTN: age 47.7 ± 12.0 years; body mass index [BMI] 30.3 ± 5.5 kg/m2; systolic [SBP]/diastolic BP [DBP] 151.6 ± 10/81.9 ± 4.2 mmHg), HIIT-pre-hypertensive (H-PreHTN: age 37.6 ± 12.0 years; BMI 31.9 ± 5.3 kg/m2; SBP/DBP 134.4 ± 3.2/74.9 ± 7.0 mmHg), and a normotensive control group (H-CG: age 40.7 ± 11.0 years; BMI 29.5 ± 4.2 kg/m2; SBP/DBP 117.0 ± 6.2/72.4 ± 4.1 mmHg). Anthropometry/body composition, BP, and metabolic substrate utilization during exercise (fat [FATox], carbohydrate [CHOox] oxidation, respiratory exchange ratio [RER], and V . O2 max), were measured before and after the 16-week HIIT intervention. Adjusted mixed linear models revealed a significant improved in V . O2 max were + 3.34 in the H-CG, + 3.63 in the H-PreHTN, and + 5.92 mL⋅kg-1⋅min-1, in the H-HTN group, however, the Time × Group interaction were not significant (p = 0.083). All the exercise types induced similar decreases on SBP (-8.70) in the H-HTN, (-7.14) in the H-CG, and (-5.11) mmHg in the H-PreHTN, as well as DBP levels (-5.43) mmHg in H-CG group (p = 0.032 vs. H-HTN group). At 16-week, no significant correlations were noted for the changes of blood pressure, cardiorespiratory fitness or exercise metabolism substrates outcomes. In conclusion, our results suggest that a 16-week HIIT-intervention improved V . O2 max and blood pressure BP, but these changes are independent of substrate utilization during exercise in normotensive and hypertensive participants with excessive adiposity.
