High strength training can reverse obesity in obese premenopausal women

A high-intensity interval exercise program lasting 4 weeks for overweight and 6 months for obese premenopausal women who were overweight obese and underweight showed that it was able to reverse obesity-related infertility in this group of seemingly healthy and fit young women.

Our results offer a novel therapeutic strategy to feminize premenopausal women by reprogramming their male breast cancer hormone synthesis toward an oral lifestyle with the result of adversely influencing the menstrual cycle and leading to fertility restoration said Masaru Harumi corresponding author of the study and researcher at Saitama University Graduate School of Medicine in Japan.

The study group which also included microbiologists and cardiologists found out that high-intensity interval exercise is highly predictive of early breast cancer incident in premenopausal women normal weight (BMI 25-27) and overweight (BMI 27-30).

This study was conducted in conjunction with a large-scale randomized control trial of 2008 overweight or obese premenopausal women when they were overweight obese and underweight in Sweden.

Individuals studied were followed for a median of 4 years. All of the women randomized to maintain weight gain maintained a BMI of 27. 5-27. 9 non-diabetes with a glucose tolerance of 18. 6-18. 9 mmolL.

The researchers saw a significant decrease in the risk of ovarian cancer mortality (relative risk 0. 51) and intrahepatic lipid-associated mortality (RR 0. 77).

Additionally women with BMI of 25-29. 9 maintained a 22 lower risk of ovarian cancer and a 17 lower risk of intrahepatic lipid-related mortality (RR 0. 48) compared with women with an average body mass index (BMI 26. 1-27. 9).

The researchers also observed a significant reduction in the risk of nonalcohol-related liver cancer (HR 0. 67) and liver fibrosis (HR 0. 69) from baseline to the end of the trial and an 18 relative improvement in total fat mass from baseline to the end of the study.

These effects of high-intensity interval training (HIIT) depend on multiple factors especially the number of sessions Harumi noted. High-intensity interval training is feasible among lean premenopausal women.
