Abstract
Six to ten years following gestational diabetes, we looked for self-reported activity and objectively measured fitness factors connected to glucose tolerance and metabolic health.
Methods: Six and ten years following GDM, women completed oral glucose tolerance tests, assessments of their body composition, and lifestyle questionnaires. A selection of subjects underwent tests to measure their maximum isometric strength, peak oxygen absorption, and fat oxidation. Women had type 2 diabetes or poor glucose metabolism. In the T2D group, VO2peak and muscle strength were the lowest. In a regression analysis, VO2peak and all strength measurements were correlated with high-density lipoprotein cholesterol and negatively with HbA1c and waist-hip ratio. Only muscle mass, however, was related to fasting and glucose area-under-the-curve. Only muscle was considered for changes between the 6- and 10-year follow-ups. Strength was linked to changes in HbA1c, but VO2peak and strength were both linked to changes in high-density lipoprotein levels and the waist-hip ratio. Peak fat oxidation and self-reported physical activity did not significantly or only sporadically correlate with glycemic factors.
Conclusion: Glycemic and other metabolic outcomes in a high-risk group after GDM were significantly correlated with objectively assessed fitness characteristics, notably muscle strength.

Introduction
The term "gestational diabetes" refers to glucose intolerance that begins or is first noticed during pregnancy [1]. Despite the fact that after giving delivery, glucose levels return to normal, up to 50% of women with GDM go on to acquire type 2 diabetes mellitus, making GDM the leading cause of T2D in young women [2]. In spite of this well-known risk, few nations, including Sweden, have formal followup procedures [3]. Lifestyle modifications after GDM can lower the risk of T2D, according to intervention studies, but the outcomes have been conflicting. In this demographic, more information is required regarding the connection between lifestyle and glucose tolerance [4]. Prior research on the effects of exercise on glucose metabolism frequently used middle-aged participants with additional risk factors or participants with T2D who had already received a diagnosis [5]. Strength has been associated with improved metabolic health and lowered T2D risk. Insulin sensitivity and glucose tolerance may also be correlated with metabolic flexibility during exercise, which is the capacity to effectively adapt substrate metabolism to glucose/fatty acid availability and metabolic demand [6]. Peak fat oxidation (PFO), the highest level of fat utilisation that typically takes place at 30–60% of an individual's maximum exercise intensity, is a common way to quantify metabolic [7]. The relationship between exercise-induced fat oxidation and glucose intolerance is still unclear, and PFO in women with GDM has not been assessed [8]. There is currently insufficient information on how various exercise types and objectively assessed fitness factors relate to declining glucose tolerance after GDM [9]. Design needs such information. Intervention programmes for GDM-affected women may also be made available to other groups [10]. Therefore, the main purpose of the study was to investigate the relationships between muscle strength, fat oxidation, self-reported activity, and glucose tolerance and other metabolic outcomes after GDM. There were three objectives: to explore for all groups of women how activity and fitness are associated with several key glycemic measurements and clinical outcomes at 10 years; to determine how activity and fitness affect longitudinal changes in glycemic and clinical variables between 6 and 10 years; and to explore whether reported activity or measured fitness variables differ between women with normal glucose tolerance, impaired glucose metabolism, or T2D at 10 years after GDM. We It is assumed that greater glycemic control and other indicators of metabolic health are linked to both aerobic fitness and muscle strength. Also, we predicted that objectively assessed fitness measures would be more strongly correlated with metabolic health than self-reported activity. The waist and hip circumferences were measured to the closest 0.5 cm in three groups based on fasting and venous glucose levels. Air displacement plethysmography was used to measure the body composition at the 10-year visit. The individuals were first approached to join 6 years after giving birth and are a part of a cohort study of women in the Gothenburg area who were diagnosed with GDM during the years. 237 women in all showed up for the initial appointment, which included anthropometric measures, an oral glucose tolerance test (OGTT), and blood sampling.
Discussion
The information from the six-year visit has been made public. Women who participated in the 6-year visit were invited to take part in a 10-year visit at Sahlgrenska University Hospital, which included blood samples, an OGTT, anthropometric measures, a body composition analysis, and questionnaires. The women were also given the option of returning to the Center for Health and Performance at Gothenburg University for additional assessments of their peak oxygen uptake, fat oxidation, isometric strength, and DXA at this time. Calculate the lean mass. Clinical assessments, self-reported physical activity and fitness measurements at 10 years, as well as clinical changes between 6 and 10 years, made up the data for the current study. Subjects completed self-assessment questionnaires about exercise routines and PA at the 10-year follow-up visit, which were based on those from the SCAPIS study. As a proxy for self-assessed activity of sufficient intensity, the subjects were asked if they had engaged in physical exercise, defined as wearing exercise clothing with the intention of exercising, increasing heart rate, and sweating, and if so, to specify the type of exercise as a measure of weekly dose. Samples of the various activity kinds were provided as a tool for self-evaluation. Running, cycling, cross-training, swimming, aerobic classes, and ball sports were used as examples of endurance training, whereas weightlifting at the gym, weightlifting courses, Pilates, and yoga were used as examples of strength training. Also, the survey asked about PA assessment based on SaltinGrimby PA level. The women were weighed when they arrived at the exercise lab following an overnight fast, and dual energy X-ray absorptiometry was used to determine their body composition. Before each measurement, the DXA was calibrated in accordance with the manufacturer's instructions. The encore programme was used to automatically analyse the total-body and localised lean and fat mass. Just the fitness variables were changed to account for lean mass using the DXA values. Aachen’s protocol was used to determine VO2peak and peak fat oxidation during a graded exercise test on a cycle ergometer. In order to identify the ideal workout intensity, the women were familiarised with the equipment and questioned about their exercise habits. Using a Jaeger OxyContin Pro, VO2 and VCO2 were measured throughout the test. Following a, the intensity increased to Increased cadence at all levels was 50 rpm for untrained women and 50 W for women who had received training.
Conclusion
In order to reach VO2peak more rapidly, cadence was increased to 60 rpm and intensity was increased by 15 W every minute once the respiratory exchange ratio (RER) was established. The following calculations were made: VO2peak, PFO, and Fatma (intensity at which PFO occurs). The presence of at least two of the following conditions was used to define VO2peak: RER heart rate was within 10 beats per minute of the highest age-predicted rate, and capillary exercising on one's own The T2D group had the lowest VO2peak, adjusted for age and BMI, of the fitness variables that can be measured objectively. PFO and the level of PFO intensity were the same in all cases. Nonetheless, all muscle groups' highest possible isometric strength was before and after adjusting for BMI, the T2D group had significantly lower rates than the others (Fig. 2B). After adjusting for lean mass, the T2D group also had considerably reduced knee extension and flexion. As the glucose tolerance groups' levels of fitness varied, we conducted a linear regression analysis on the complete female population to further investigate the connection between fitness levels and all clinical measurements at the 10-year visit. There were minimal significant relationships between clinical factors and self-reported exercise after BMI and age adjustments. The only factors that were positively correlated with both hyperglycemia and other metabolic variables were strength training and overall PA level. But not glycemic factors, endurance exercise were linked to decreased fat mass and increased HDL. Contrary to expectations, self-reported walking was connected to a higher HOMA-IR. The results in hyperglycemia and other metabolic indicators were explained by objectively measured fitness characteristics using linear regression models. Muscular strength tests were especially significant since they all highly correlated with reduced HbA1c and, in some cases, with decreased OGTT glucose and insulin resistance. Together with VO2peak, all strength measurements were also significantly correlated with lower waist-hip ratios, higher fatfree mass, and higher HDL levels. PFO and Fatma were not connected to glucose factors. Nevertheless, PFO was linked to greater levels of HDL and fat-free mass. Lean mass was determined using DXA on the same day as the strength tests in order to study the significance of muscle mass. Age was also taken into account. Their analyses still demonstrated such quality.
