AB  - BACKGROUND: This study aimed to explore muscle strength production and its 
      underlying neuromuscular characteristics in sedentary and trained individuals 
      with intellectual disability (ID) compared with healthy sedentary individuals. 
      METHODS: Three adult groups (age: 25.07 +/- 0.70) consisting of sedentary 
      individuals with ID (IDSG), trained individuals with ID (IDTG) and a control 
      group (CONT) participated in the present study. Peak torque (PT) during maximal 
      voluntary isometric contraction, voluntary activation level (VAL), surface 
      electromyography (sEMG) recordings, electrophysiological (M(max) ) and 
      potentiated twitch torque (PTT responses) of the knee extensor muscles and thigh 
      muscle volume were assessed. RESULTS: Compared with CONT and IDTG, respectively, 
      IDSG presented significantly lower PT (-48% and -42%), VAL (-24% and -9%), sEMG 
      (-49% and -29%), M(max) (-41% and -39%) and PTT (-32% and -28%) values. These 
      deficits were reduced between IDTG compared with CONT (i.e. PT: -10%; VAL: -16%; 
      and sEMG: -28%) or did not differ anymore (PTT and M(max) ). Normalising PT to 
      thigh muscle volume and/or computing theoretical PT value overwhelm strength 
      production differences between IDTG and CONT. Training background influences the 
      outcomes with IDTG exhibiting greater PT, VAL, sEMG, M(max) and PTT than IDSG. 
      CONCLUSIONS: Strength production deficit in IDSG was related to both muscular and 
      neural characteristics compared with healthy controls whereas this deficit mainly 
      arises from neural characteristics for IDTG.
