AB  - The aims of this study were to 1) examine the influence of age and occupation on 
      maximal and rapid strength of the lower-extremity muscles and 2) examine the 
      relationship between maximal and rapid strength and physical workload (work index 
      (WI)) in the blue-collar (BC) cohort. Peak torque (PT) and peak rate of torque 
      development (peakRTD) of the leg extensors (LE), leg flexors (LF), and plantar 
      flexors (PF) were assessed in 47 young (age = 24.1 +/- 2.4 years) and 41 
      middle-aged (52.4 +/- 5.2 years) white-collar (WC) and BC men. Middle-aged workers 
      exhibited lower PT for all muscles, and peakRTD for the LF and PF muscles. A 
      positive relationship (r = 0.59; P < 0.01) was observed between WI and peakRTD 
      for the PF in the young BC workers, however, this relationship was negative 
      (r = -0.45; P = 0.053) for the LF of the middle-aged BC workers. Lowering 
      physical work demands and/or incorporating effective health-related practices for 
      employees may be appealing strategies to enhance aging workers' productivity and 
      longevity in the workforce.
