Body composition is an important component of overall health. The development of digital assessment methods has led to increased interest in devices that allow users to monitor their own body composition. Smartphone applications with three-dimensional optical imaging (3DO) capabilities are a user-friendly technology capable of predicting percent body fat (BF%) from relevant body measurements. PURPOSE: To determine the validity of two BF% equations using smartphone 3DO data, as compared to a 4-compartment (4C) model criterion, and to produce a new BF% estimation equation. METHODS: At a single laboratory visit, 60 participants (28 F, 32 M; [mean ± SD] …

Purpose: Many modern-day children are at risk of pediatric dynapenia (muscle weakness). We examined the effects of a 12-week resistance training (RT) program on neuromuscular function and body composition parameters in pubertal children with a risk of dynapenia. Methods: Twelve children (13.4 ± 0.9 y) with dynapenia performed a progressive RT program consisting of knee extension and flexion, bench press, abdominal crunch, back extension, lateral pull-down, elbow flexion, and upright row (1–2 sets of 10–15 repetitions/exercise) twice/week for 12 weeks. Outcome measures included one-repetition maximum (1-RM) strength, maximal voluntary isometric contraction (MVIC) torque, rate of torque development (RTD), electromyographic (EMG) …
