Comparison of Two BioCircuit Programs: Impact on Physical Fitness and Body Composition in Adults Aged 30-65

Participants in the Tone Your Body group follow a 12-week BioCircuit training programme designed to improve body composition and muscle toning. The programme consists of six total-body strength exercises and two cardio exercises in a circuit format. Each exercise is performed for 45 seconds, followed by a 40-second rest between machines. The endurance exercises are performed for 3 minutes and 35 seconds each. The eccentric phase of each strength exercise is overloaded by 20% to maximise muscle development.

Participants in the Boost Performance group follow a 12-week BioCircuit training programme designed to increase strength and endurance. The programme consists of six strength exercises and two cardio exercises, also in a circuit format. Each exercise is performed for 45 seconds, with 40 seconds rest between machines, and the endurance exercises are performed for 3 minutes and 35 seconds. The strength exercises use a viscous resistance mechanism to increase strength and endurance. Participants also undergo performance tests including the jump and reach test, one minute squats and one minute push-ups.
