Research by Smith (2021) indicated that a longer running surface, between 55 to 60 inches, accommodates different strides, especially for taller runners.
Incline options: Adjustable incline settings provide varied workout experiences that simulate outdoor running conditions. Many models offer incline angles from 0% to 15%. A study by Adams et al. (2023) showed that running on an incline can increase cardiovascular benefits and muscle engagement.
Cushioning technology: Advanced cushioning reduces impact on joints and enhances comfort during long training sessions. Treadmills equipped with multi-zone cushioning can provide tailored support for different parts of the foot. Research by Lee (2020) emphasized that runners with lower leg injuries reported improved comfort levels when using treadmills with proper cushioning systems.
Integrated training programs: Treadmills with built-in workouts and connectivity options can keep runners engaged.
