Growth hormone release during resistance exercise is affected primarily by: A. The type of resistance training protocol, with shorter rest periods producing higher serum concentrations than longer rest protocols B. Only the total amount of weight lifted C. Exclusively by the athlete's age, regardless of exercise protocol 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 4: Endocrine Responses to Resistance Exercise DCO Code: 1.F2 NOTE: Image is for illustration purposes, not needed to answer the question.

Which of the following is a characteristic of Type I muscle fibers? A. High force production and rapid fatigue B. High fatigue resistance and slow contraction speed C. High anaerobic enzyme content and white color 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 1: Structure and Function of Body Systems DCO Code: 1.A1 NOTE: Image is for illustration purposes, not needed to answer the question.

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!

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.

Which type of joint allows virtually no movement and is found between the bones of the skull? A. Cartilaginous joints B. Synovial joints C.
