The search is on to recruit about 100 women for a new Charles Sturt University (CSU) study comparing the effects of four different types of exercise on overall health and wellbeing.PhD student Mr Joshua Cooper from the University's School of Exercise Science, Sport and Health is seeking women aged between 55 and 70 years to participate in three exercise sessions a week for 16 weeks.The free training sessions will be conducted at the University gym in Bathurst to compare four different exercise groups: aerobic endurance exercise training (cycling), whole-body resistance exercise training (weights), and two differing doses of a combination of the endurance and resistance training exercise groups.Mr Cooper said, "I want to see if the women are able to get the same health benefits by doing 50 per cent resistance and 50 per cent endurance programs as by undertaking 100 per cent strength or endurance programs."So basically, do you get the same results for half the amount of work and time put in at the gym?"It is well documented that middle to older aged adults need both resistance training to offset the loss of muscle mass and endurance training for cardiorespiratory health and fitness."I want to promote a combination of both training styles in this age bracket and show via progressive and feasible exercise programs it can be integrated into everyday life and you can receive the associated health benefits from exercise."Women interested in participating in the study will need to undergo initial screenings from their general practitioner and a Bathurst cardiologist. To be eligible, women must have no current cardiovascular or metabolic disease, and currently participate in less than or equal to two exercise sessions per week. For further eligibility details, and anyone interested in the study, should contact Mr Cooper on telephone (02) 6338 6101, mobile 0416 626 300 or email jcooper@csu.edu.au.
