AB  - Retraining and resuming competition following surgery is challenging for athletes 
      due to the prolonged period of reduced physical activity and subsequent 
      alteration of body composition and physical performance. This is even more 
      challenging for master athletes who endure the additional effect of aging. Within 
      this context, the purpose of this study was to evaluate the feasibility and 
      benefits that evidence-based nutritional and training recommendations could have 
      on the time course of reconditioning and retraining following hip arthroplasty in 
      an endurance master triathlete. During 38 weeks (from 6 weeks prior to surgery 
      through to the return to competition in week 32), the athlete was provided with 
      detailed training and nutritional recommendations. Dietary intake (via the remote 
      food photographic method), body composition (via DXA), peak oxygen uptake 
      (VO(2peak)), peak power output (PPO), cycling efficiency (GE), and energy 
      availability (EA) were assessed 6 weeks pre- and 8, 12, 18, 21, and 25-weeks 
      post-surgery. Training load was quantified (via TRIMP score and energy 
      expenditure) daily during the retraining. Total body mass increased by 8.2 kg 
      (attributable to a 3.5-4.6 kg increase in fat mass and lean mass, respectively) 
      between week -6 and 8 despite a reduction in carbohydrate (CHO) intake 
      post-surgery (<3.0 g/kg body mass/day). This was accompanied with a decrease in 
      VO(2peak), PPO, and GE due to a drop in training load. From week 7, the athlete 
      resumed training and was advised to increase gradually CHO intake according to 
      the demands of training. Eventually the athlete was able to return to competition 
      in week 32 with a higher PPO, improved VO(2peak), and GE. Throughout retraining, 
      EA was maintained around 30 kcal/kg Lean Body Mass/day, protein intake was high 
      (~2 g/kg/day) while CHO intake was periodized. Such dietary conditions allowed 
      the athlete to maintain and even increase lean mass, which represents a major 
      challenge with aging. Data reported in this study show, for the first time, the 
      conditions required to recover and return to endurance competition following hip 
      surgery.
