This prospective case study evaluated an experienced female figure competitor during contest preparation, 2 competitions, and a recovery period. Twelve laboratory sessions were conducted over 8 months. At each visit, body composition was assessed by 4-compartment model, resting metabolic rate (RMR) by indirect calorimetry, and neuromuscular performance by peak force and rate of force development (RFD) on a mechanized squat device. Caloric intake ranged from 965 to 1,610 kcal[middle dot]d-1 (16.1-24.8 kcal[middle dot]kg[middle dot]BM-1; 18.2-31.1 kcal[middle dot]kg[middle dot]FFM-1), with varying macronutrient intakes (CHO: 0.3-4.8 g[middle dot]kg-1; PRO: 1.7-3.0 g[middle dot]kg-1; and FAT: 0.2-0.5 g[middle dot]kg-1). Body fat was reduced from 20.3 to 12.2% before the first competition and declined to 11.6% before the second competition. Fat-free mass increased by 2.1% before the first competition and peaked at 4.6% above baseline in the recovery period. Resting metabolic rate decreased from 1,345 kcal[middle dot]d-1 at baseline to a low value of 1,119 kcal[middle dot]d-1 between competitions. By the end of recovery, RMR increased to 1,435 kcal[middle dot]d-1. Concentric and eccentric peak forces declined by up to 19% before the first competition, experienced perturbations in the inter-competition and recovery periods, and remained 5-8% below baseline at study termination. Similarly, RFD decreased by up to 57% before the first competition, was partially recovered, but remained 39% lower than baseline at study termination. Despite favorable body composition changes, neuromuscular performance was impaired during and after the competitive season in an experienced female physique competitor.
