Tele-exercise delivers remote physical activity programs via digital platforms, enhancing accessibility and adherence, making it a promising strategy to address obesity among workers. This study aimed to evaluate the effects of tele-exercise programs on body fat percentage, lipid profile, mental health measures and Sirtuin 1 (SIRT1) gene expression measured via venipuncture & RT-PCR in obese office employees. A total of 33 overweight or obese employees (male/female, 18-45 years old, Body Mass Index (BMI) 23-30 kg/m2) were randomly assigned to the strength (SE) group, strength-cardio (SC) group, and control (CT) group. The strength exercise protocol included core training, circuit training, High Intensity Interval Training (HIIT) and Tabata training; cardio exercise includes low-high impact aerobic exercises. Each group was given nutrition education, whereas the two intervention groups participated in tele-exercise three times/week for twelve weeks. Tele-exercise was delivered via ZOOM application. Mental health indicators were measured using the Depression Anxiety Stress Scale (DASS-42) questionnaire. Compliance levels between intervention groups did not differ significantly (p>0.05). There was a significant reduction in bodyweight in the SC group (p=0.046). Blood High Density Lipoprotein (HDL) levels increased only in the SC group (0.50 mg/dL), but decreased in the SE group and CT group. SIRT1 gene expression increased in SE and CT groups (2.39- and 5.33-fold, respectively), whereas a significant decrease was observed in the SC group (p=0.043). Only the SE group showed a significant reduction in stress level (p=0.03), with a decrease of 30.9%. Strength exercise intervention improves total cholesterol level by -19.09 mg/dL.

IgA is widely used as Upper Respiratory Tract Infection (URTI) risk marker, as a lower concentration in sIgA indicates a higher incidence of URTI. This study aimed to investigate the effect of different types of exercise; combined with Tempeh consumption in increasing sIgA concentration in saliva sample. 19 sedentary male subjects aged 20-23 were recruited and assigned into 2 groups based on the exercise type, endurance (n=9), and resistance (n=10). These subjects underwent 2 weeks of Tofu and Tempeh consumption, then were assigned to do exercises based on their groups. This study showed an increased mean value of sIgA concentrations in the endurance group; the baseline value, after food treatment, and after food and exercise treatment were 71.726 ng/mL, 73.266 ng/mL, and 73.921 ng/mL, respectively for Tofu treatment; and 71.726 ng/mL, 73.723 ng/mL, and 75.075 ng/mL, respectively for Tempeh treatment. While in the resistance group, there was also an increase in the mean value of sIgA concentrations; baseline, after food treatment, and after food and exercise treatments were 70.123 ng/mL, 71.801 ng/mL, and 74.430 ng/mL, respectively for Tofu treatment; and 70.123 ng/mL, 72.397 ng/mL, and 77.216 ng/mL, respectively for Tempeh treatment. These results indicated that combining both Tempeh consumption and moderate intensity resistance exercise was more effective to increase sIgA concentration. This study showed that combining moderate intensity resistance exercise with consumption of 200 gr Tempeh for 2 weeks was more effective in increasing sIgA concentration; compared to endurance exercise and Tofu consumption.

This study aimed to evaluate the in sacco nutrient degradability of total mixed ration (TMR) silage containing intact and defatted black soldier fly (BSF) larvae. The study evaluated four dietary treatments and six replications. The treatments consisted of control TMR silage without BSF larvae (R1), 20% intact BSF larvae + 80% TMR silage (R2), 20% chemically defatted BSF larvae + 80% TMR silage (R3), and 20% mechanically defatted BSF larvae + 80% TMR silage (R4). Samples were placed in polyester bags and incubated in the rumen in sacco up to 72 h. Nutrient degradability was evaluated for each time point interval. Results revealed that the lowest dry matter degradability (DMD) was found in R1 compared to all treatments (p < 0.05), while the highest DMD was found in R2 (p < 0.05). The highest organic matter degradability was found in R2 compared to R1, R3 and R4 (p < 0.05). Addition of BSF larvae to TMR silage increased the crude protein degradability (p < 0.05). In conclusion, inclusion of both intact and defatted BSF larvae into TMR silage did not have any adverse effects on nutrient profiles and showed a good nutrient degradation values in the rumen.
