High-intensity interval training (Hiit) has recently been touted as a one-size-fits-all solution for fitness training among all brackets of health due to its proven efficiency to deliver fitness goals in less time, but a new study by Rutgers university warns it also raises the potential for injuries.
The study, which appears in the Journal of Sports Medicine and Physical Fitness, acknowledged that while this type of training is effective in improving cardiorespiratory fitness, boosting energy, and promoting lean muscle mass and fat loss, it also increases injuries resulting from exercise equipment, such as barbells, kettlebells, and boxes, or callisthenics, such as burpees, push-ups, and lunges, that are common to these programs. Most injuries involved knees, ankles, and shoulders.
The researchers have advised that since knee and ankle sprains and strains were the most common injuries from high-intensity interval workouts, people do neuromuscular training focusing on strength, jumping, and balance and programs to improve flexibility before starting Hiit exercises.
Co-author Nicole D. Rynecki, a student at the medical school, said: “We certainly do not want to discourage people from this type of exercise because of its numerous health benefits, but recommend that they understand the pre-existing conditions and physical weaknesses that may predispose them to injury.”
