When weight training, the length of the interval between sets does not affect the number of calories burned, according to a study in the November issue of Medicine and Science in Sports and Exercise .
Experts say the findings have important implications for weight control exercise programs.
Participants completed both protocols in two different sessions one week apart. Each protocol began at the leg press station and included two circuits for a total of 16 stations. The data showed that each protocol burned about the same number of calories. Researchers say that this finding has some practical applications for resistive exercise programs. Haltom, who is an exercise physiologist at Branch Medical Clinic in Mayport, Fla., says this means everyone can benefit from weight training regardless of fitness level.
