The Dose-response Effects of High Intensity Functional Training on Metabolic Syndrome Risk Factors

Summary

This study aims to explore the dose effects of three weekly volumes of high-intensity functional training (HIFT) on apolipoprotein B (ApoB), triglyceride (TG) and cholesterol (CHOL) content of low-density lipoproteins (LDL), very low-density lipoproteins (VLDL), and high-density lipoproteins (HDL) particles, fasting insulin and glucose, glycosylated hemoglobin (HbA1c), and endothelial function after a 12-week training program. Secondarily, this study aims to also explore the subjective dose-responses of "exercise enjoyment" and "intention to continue" after this 12-week training program.

Conditions

• Metabolic Syndrome
• Atherogenic Dyslipidemia
• Insulin Resistance
• Endothelial Dysfunction

Interventions

BEHAVIORAL

HIFT 1x/week

HIFT is a time-efficient modality of exercise combining high-intensity aerobic and resistance training using minimal equipment. HIFT 1x/week represents a dose of one HIFT workout per week.

BEHAVIORAL

HIFT 2x/week

HIFT is a time-efficient modality of exercise combining high-intensity aerobic and resistance training using minimal equipment. HIFT 2x/week represents a dose of two HIFT workouts per week.

BEHAVIORAL

HIFT 3x/week

HIFT is a time-efficient modality of exercise combining high-intensity aerobic and resistance training using minimal equipment. HIFT 3x/week represents a dose of three HIFT workouts per week.
