A strength coach designs a bone health program for a 55-year-old female with low BMD (osteopenia, T-score -1.5) at the hip. The program includes: - Moderate-load resistance training (65% 1RM, 8-12 reps) - Elliptical machine 45 min, 3x/week - Yoga and flexibility work 2x/week Critique this program for bone adaptation optimization. A. The program is suboptimal for bone growth: it lacks high-impact loading, multi-directional forces, and sufficient mechanical stress. Moderate loads (65% 1RM) fall below the intensity needed for robust osteogenic stimulus. Elliptical and yoga provide minimal impact or directional variance. Recommended additions: high-impact activities (jumping, running), heavy compound lifts (>80% 1RM), and multi-planar resistance exercises. B. The program is optimal; moderate loading is best for bone health C. Bone adaptation requires only resistance training with no impact component Answer in the poll, then explain your rationale below in the comments! I'll follow up with my breakdown of the question after enough people have responded.

Which body movement is an example of a second-class lever? A. Knee extension B. Elbow flexion with biceps curl C. Plantar flexion (raising on toes) Answer in the poll, then explain your rationale below in the comments! I'll follow up with my breakdown of the question after enough people have responded. From Chapter 2: Biomechanics of Resistance Exercise DCO Code: 1.C2 NOTE: Image is for illustration purposes, not needed to answer the question.Use something that shows lever concepts broadly without isolating plantar flexion.

PROGRAM-VETTING: A coach designs a bench press program using linear elastic bands looped over a barbell. As the athlete presses, the band stretches and resistance increases (accommodating resistance). The coach claims this better develops lockout strength. Is this biomechanically sound? A. No; elastic resistance increases in positions where the joint is strongest, but also shortens fastest, reducing time under tension B. Yes; elastic resistance increases as the joint approaches full extension, matching where shoulder extensors are mechanically strongest C. No; elastic resistance provides least resistance early in the range where muscles are weakest, opposite of the human strength curve Answer in the poll, then explain your rationale below in the comments!

Creatine phosphate (CP) primarily serves what role during exercise? A. It rapidly replenishes ATP during short, high-intensity activities B. It buffers lactate accumulation in muscle C.
