18 Benefits of regular exercise on body composition and cardio-respiratory function in ex-servicemen residing in the tropics

Abstract

Typically the health and quality of life exhibited by Australian ex-servicemen resident in the tropics is poor. The current study examined the effects of regular exercise on body composition and cardio-respiratory function of ex-servicemen who served in varying theatres of conflict. One hundred and twenty three Australian ex-servicemen (mean age 54.2, range 28-77 yrs; height 1.75 0.63 m; mass 95.80 1.67 kg) currently residing in the tropics (North Queensland region) volunteered for this study. All participants received medical clearance from their general practitioner prior to undertaking a 6-month regular exercise programme. Cardio-respiratory and anthropometry measurements were obtained prior to and following the exercise programme. The exercise programme consisted of combined aerobic and resistance training of at least 45 minutes duration, 1 to 2 days per week. Approximately 84% of the participants completed the programme with 73.2% undertaking 1-2 sessions per week while 26.8% completed more than 2 sessions per week. Paired t-test analysis indicated significant (p<0.05) changes in resting systolic and diastolic blood pressure, all skinfold measurements, waist and hip girths, exercise heart rates and VO2max. Regular exercise of at least 1-2 sessions per week for 6 months significantly improved the body composition and cardio-respiratory function of Australian ex-servicemen residing in tropical North Queensland.
