Brief Summary

Spot reduction, referring to local body fat reduction, pertains to subcutaneous adipose tissue utilization from specific body parts during exercise. Its existence has been keenly debated, although generally accepted not to occur during exercise. However, it is based on not only equivocal data - commonly the training protocol typically applied is based on strength rather than endurance training. The investigators sought to test this assumption by utilizing endurance based exercise controlling for energy expenditure and using dual x-ray absorptiometric measures to assess body composition before and after training.

Study Arms (2)

abdominal aerobic endurance exercise

EXPERIMENTAL

Subjects were combining treadmill running at 70% HRmax (27 minutes) with 4x4minutes (30-40% maximal strength, 1RM) of torso rotation and abdominal crunches (57 minutes), 4 d per wk for 10 weeks

Other: Abdominal aerobic endurance exercise

Control group

ACTIVE COMPARATOR

Subjects performed only treadmill running (45 minutes) at 70% HRmax for 4 d per week for 10 weeks.

Other: Control training intervention
