Abstract

The use of a ketogenic diet with an increased proportion of fat is rampant lately, both as a therapy or even lifestyle. The use of a ketogenic diet is feared to cause dyslipidemia. It will also lead to atherosclerosis and thrombosis. This study aimed to determine the effect of a high-fat diet on HDL, LDL, and HDL/LDL ratio in mice. Thirty male Mus Musculus, 2-3 mo, 15-25 g divided into five groups diet. K1 (12% fat, 20% protein, 62% carb), K2 (30% fat, 60%protein), K3 (45% fat, 45% protein), K4 (60% fat, 30% protein) and K5 (75% fat, 15% protein) for 4 weeks. Feed and water by adlibitum. Blood for serum was taken from the ventricle, while in the measurement of HDL serum level, the LDL used ELISA. Normality of data analyzed by Shapiro Wilk, and homogeneity by Levene test. HDL serum was analyzed using equality test followed by Games Howell, LDL serum and ratio of HDL/LDL was tested by ANOVA followed by LSD with significance 0,05. HDL serum in K1 (62,50±9.94) mg/dL, K2 (78,40±18,76) mg/dL, K3 (79,00±3,81) mg/dL, K4 (80,00±2,16) mg/dL, and K5 (83,50±5,62) mg/dL with p<0,05 in K1, K2 to K3, K4 and K5. LDL serum in K1 (21,67± 4,80) mg/dL, K2 (23,00±12,70) mg/dL, K3 (18,40±4,34) mg/dL, K4 (24,00 ±1,83) mg/dL and K5 (22,00 ± 4,08) mg/dL with p>0,05. Ratio HDL/LDL K1 (3,01±0,91), K2 (4,10±1,86), K3 (4,53±1,5), K4 (3,35±0,34), and K5 (3,96 ± 1,25) with p>0,05.

Abstract

Breast cancer treatments, particularly chemotherapy, have been associated with significant declines in cardiopulmonary fitness, a key determinant of functional independence and survival. VO2peak, a marker of cardiopulmonary function, is often reduced in patients undergoing chemotherapy, increasing morbidity risks. Researchers have proposed exercise interventions to mitigate these effects. However, most studies focused on moderate-to-high-intensity regimens, with limited data on the efficacy of low-intensity aerobic exercise. This study aimed to explore the impact of low-intensity cycle ergometer aerobic exercise on VO2peak in women undergoing chemotherapy for breast cancer. A randomized controlled trial with twenty participants randomly assigned to an intervention group (n = 10, low-intensity aerobic exercise twice per week for 8 weeks) or a control group (n = 10, usual care). VO2peak was estimated using the 30-Second Sit-to-Stand (30STS) test. Statistical analysis was performed using paired and independent t-tests, with effect size (Cohen’s d) calculated to assess clinical significance. The intervention group demonstrated a significant increase in VO2peak (Δ= +1.93 mL/kg/min, p < 0.001), while the control group showed a non-significant change (Δ= +0.25 mL/kg/min, p = 0.31). Between-group analysis suggested a significant difference in favour of the intervention (p = 0.02, Cohen’s d = –2.56), indicating a large effect size.
