PURPOSE: To study the effects of regular walking during a golf game on vari
ous health and fitness indicators in middle aged men.
METHODS: Study subjects were 55 healthy male golfers aged 48 to 64 years wh
o had been sedentary during the 7 months before the study, and 55 age-match
ed, similarly sedentary controls. During the 20-week study, those in the in
tervention group were encouraged to play golf two to three times a week; th
e controls were not. Measurements of body composition, cardiorespiratory pe
rformance, motor and musculoskeletal fitness, blood pressure, and serum lip
id, glucose, and insulin levels were obtained at baseline and after the 20-
week study.
RESULTS: Walking during a golf game was a practical and safe form of physic
al activity with high adherence. It significantly increased aerobic perform
ance and trunk muscle endurance, with a net difference (pretraining to post
training change between the golfers and controls) of 36 seconds (95% confid
ence interval [CI]: 19 to 53 seconds, P < 0.001) for treadmill walking time
and 13 seconds (95% CI: 2 to 24 seconds, P = 0.02) for static back extensi
on. In addition, regular walking favorably affected body composition, inclu
ding reductions in weight of 1.4 kg (95% CI: 0.6 to 2.1 kg, P < 0.001), in
waist circumference of 2.2 cm (95% CI: 1.0 to 3.3 cm, P < 0.001), and in ab
dominal skin fold thickness of 2.2 cm (95% CI: 0.9 to 3.4 cm, P = 0.001). G
olfers also had significantly greater increases in serum high-density lipop
rotein (HDL) cholesterol levels and ill the ratio of HDL cholesterol to tot
al cholesterol.
CONCLUSIONS: Regular walking had many positive effects on the health and fi
tness of sedentary middle-aged men. Walking during a golf game is character
ized by high adherence and low risk of injury and is therefore a good form
of health-enhancing physical activity. Am J Med. 2000;109:102-108. (C) 2000
