This thesis investigates into SB and PC, in UK office workers, who are below retirement age.

The grip strength and walk speed of individuals were relatively reduced compared to norms and may highlight impaired PC due to the sedentary occupation. A calisthenics exercise intervention resulted in considerable reductions in workplace sitting (-35 mins.day -1) and provided improvements to balance (composite: +1.3%, p>0.05; anterior: +2.6%, p<0.05).
