Introduction

The CTRP adipokine family has 15 members (CTRP-1 to CTRP-15), with localised tissue expression. Adipocytes are the primary tissue of high expression for CTRP-2 and CTRP-9. In both human and animal models of obesity, there is an increase in CTRP-2 and CTRP-9 secretion .Transforming growth factor (TGF)-family secretory proteins, including as GDF-8 and GDF-15, are known as GDFs. Myostatin, also known as GDF-8, is essential for maintaining the homeostasis of skeletal muscles, and studies have shown that GDF-8 expression levels are inversely correlated with fat loss, insulin sensitivity, and glucose absorption .With a possible function in lipid metabolism, GDF-15 levels, also known as macrophage inhibitory cytokine (MIC-1) generated by adipocytes, positively correlate with obesity. Treatments to lessen obesity-related health issues are still difficult to find. The success of pharmacological and surgical treatments for obese patients varies and is coupled with negative effects. The management of obesity and its accompanying problems holds promise when energy intake is reduced, energy expenditure is increased, and muscle mass is increased .The forms of exercise, however, have an impact on the results of regular exercise training to manage obesity and linked disorders .In obese people, for instance, CrossFit training (a high-intensity mixed exercise model of concurrent strength and endurance performance) lowers lipid oxidation .This high-intensity functional training (HIFT) exercise modality entails exercise sets with or without rest periods in between sets, and it has been shown to increase IL-6 and IL-10 activity ,as well as to increase aerobic capacity, improve muscular endurance, increase lean body mass, and decrease body fat. Transforming growth factor (TGF)-family secretory proteins, including as GDF-8 and GDF-15, are known as GDFs. Myostatin, also known as GDF-8, is essential for maintaining the homeostasis of skeletal muscles, and studies have shown that GDF-8 expression levels are inversely correlated with fat loss, insulin sensitivity, and glucose absorption [1,2].

Methods

All participants underwent a physical assessment by a doctor and a clinical exercise physiologist during the initial visit. Each participant filled out a Physical Activity Readiness Questionnaire (PAR-Q) and gave written informed permission papers .The initial visit included an explanation of the study's protocols, and all of them were approved by the Islamic Azad University's Research and Ethics Committee (Ethics code: IR-IAU1400-47). The Declaration of Helsinki's most recent revision was followed in all processes. There were 101 participants who initially volunteered for the study after calling in public spaces like gyms, medical clinics, hospitals, and social networks. Of these, 33 were ruled ineligible, leaving 68 participants in the study (mean age: 27.6 8.4 yrs; mean height: 167.8 3.1 cm; mean weight: 94.7 2.0 kg; mean BMI: 33.6 1.4 kg/m²), who were split into 4 groups of 17 participants BMI > 30 kg/ m², inactivity for the previous six months, absence of endocrine, metabolic, or cardiovascular illnesses, and abstinence from alcohol use were the inclusion criteria for the study [3-5].

Discussion

Our study's measurement of the VO2 peak and other studies showing that CrossFit exercise increases muscle mass and improves insulin sensitivity support the idea that increased fat loss generated by this type of training reflects changes in aerobic capacity. Other studies showing that HIIT enhances insulin sensitivity are consistent with our findings .In obese animal models and people, adipokine levels are favourably correlated with adipose tissue levels .Our study's variations in both CTRPs could be attributed to alterations in lipid profiles and body weight. Our results show that HIFT and astaxanthin decreased body weight and lipid profiles while raising HDL-C levels; these improvements were more pronounced when astaxanthin was added to the exercise regimen. Another study that used two dosages of astaxanthin discovered a decrease in TG while an increase in HDL-C. Other 12-week trials of combined resistance and aerobic exercise decreased body weight and CTRP5 and CTRP3 levels in obese women confirm our findings [6].

Conclusion

Our findings—which show decreased GDF15 levels after HIFT training— contradict those of earlier research, which found increases in GDF15 levels with exercise. This discrepancy may be due to variations in training methods. This study used repeated measures and a longitudinal design to examine changes in infants' and toddlers' development using an ASQ, a routinely used clinical screening instrument, from before to throughout the pandemic in a large and diverse population. In line with other research, we discovered that households with lower SES and members of racial and ethnic minorities were more likely to report experiencing social and financial challenges during the COVID-19 epidemic. However, neither categorical nor continuous outcomes were able to account for within-individual differences in children's growth.
