摘要：Background and Study Aim: Obesity is deeply related to a broad range of internal conditions, including heart disease, hypertension, and
diabetes, as well as several musculoskeletal conditions, such as pain, stiffness, loss of joint mobility, osteoarthritis,
tendinitis, and back pain. The purpose of this study was the influences of weight reduction programs
consisting of caloric restriction and/or exercise on the vital age of men with obesity.
Material and Methods: For 12 weeks, 32 subjects (GE) attended exercise class 3 days/week and 79 subjects (GCE) concurrently attended
exercise class 3 days/week and a caloric restriction class 1 day/week. Changes of weight and the following
nine necessary variables were assessed to compute vital age: subscapular skinfold thickness, systolic
blood pressure, total cholesterol, triglycerides, oxygen uptake and heart rate corresponding to lactate threshold
(VO2LT and HRLT, respectively), stepping side-to-side, one leg balance with eyes closed and forced expiratory
volume in one second.
Results: Changes of weight for the subjects in the GE and GCE were −2.4% and −13.8%, respectively (p<0.01 for both).
GE showed amelioration of subscapular skinfold thickness, total cholesterol and side stepping, whereas every
component of vital age except for HRLT was ameliorated in GCE. The stronger influences on four components
of vital age including systolic blood pressure, total cholesterol, triglyceride and forced expiratory volume in
one second were detected in the GCE. As a result, improvement of vital age was detected within GC and GCE,
by 8.4 % and 18.9 %, respectively (p<0.01 for both). When intergroup comparison was made, the improvement
in GCE was greater than that in the GC (p<0.01).
Conclusions: Vital age was predominantly affected by caloric restriction, and combining exercise with caloric restriction
yielded additional improvement in vital age.
