Comparative Study Between The Heavy Duty Training Method And The Classical Training Method

Purpose: The study aims to compare the effectiveness of the Heavy Duty training method with the classical method in the development of muscle strength and hypertrophy, focusing on the biceps brachii and triceps surae muscle groups. Methods: The research was conducted over a period of 6 months at Panoramic Gym in Arad, involving a sample of 45 volunteers randomly divided into two groups: an experimental group (E.G.) and a control group (C.G.). The E.G. followed the Heavy Duty training method, while the C.G. followed the classical method. Strength tests (pull-ups and calf raises) and anthropometric measurements (arm and calf circumference) were used. Data were analyzed using arithmetic mean and standard deviation. Results: The E.G. recorded a 19.9% increase in pull-ups and 9.7% in calf raises, while the C.G. showed increases of 16.5% and 4.9%, respectively. Arm circumference increased by 3.3% in the E.G. and 2.7% in the C.G., and calf circumference by 1.9% vs. 1.5%. Conclusions: The Heavy Duty method generated superior progress in muscle strength and hypertrophy compared to the classical method, demonstrating greater efficiency in stimulating physiological adaptations through short and intense workouts, suitable for advanced athletes.
