Health and fitness benefits using a heart rate intensity-based group fitness exercise regimen
Inactivity leads to morbidity and mortality, while novel and engaging approaches to fitness improve health outcomes. The current study examined an 8-week commercial group exercise regimen for high intensity interval training (HIIT) in order to examine comprehensive metrics of health and fitness. Aerobic fitness, body composition, resting metabolic rate, blood cholesterol and glucose, in addition to resting blood pressure were quantified in a laboratory setting independent of the training facilities. Exercise training utilized multimodal HIIT-based exercises and work intensity was gauged by real-time heart rate feedback. All participants completed the required two sessions per week. Pre-Post analyses indicate aerobic fitness (Pre O2max = 36.8 ml•kg-1•min-1; Post O2max = 40.8 ml•kg-1•min-1), % fat (Pre = 28.1%; Post = 27.0%), resting metabolic rate (Pre = 1557 kcals; Post = 1664 kcals), resting blood pressure (Pre = 128.8/78.1 mmHg; Post = 116.7/75.4 mmHg), and circulating triacylglycerol (Pre = 100.0 mg/dl; Post = 78.7 mg/dl) were significantly altered. This study quantified improvements in aerobic fitness, body composition, resting metabolic rate, resting blood pressure, and triacylglycerol after an 8-week HIIT regimen. The implications of heart rate (HR) monitoring within franchised group exercise with wearable technology serves as an unexplored scientific approach to understand novel exercise prescriptions on health-fitness outcomes. Future research should investigate sociological aspects of program adherence, while biological applications should examine the adaptive stimuli of HIIT training on health and fitness improvements.
