Welcome back to the Barbell Medicine Podcast, where we bring Modern Medicine to

Strength and Strength Condition we bring Modern Medicine to Strength and Strength and

Conditioning to Modern Medicine.

I'm your host, Dr. Jordan Figenbaum.

This is part three of the Resistance Training for Kids Series written by Dr. Derek Miles.

Derek Miles is a physical therapist working at Stanford Children's Hospital. Parts 1 and part 2 are both linked in the description below as well as the text version of part 3.

We'll start with the narration. Part 3, Musculoskeletal Adaptation to Resistance Training.

Part 3 will focus on the specific effects of resistance training on youth athletes.

As mentioned in the previous parts of this series,

resistance training is effective for increasing performance and reducing the risk of injury and athletes.

Here, we will explore the mechanisms by which it may elicit these effects.

There is a posity of research directly related to the tissue change in adolescents

due to the invasive nature of methods such as muscle biopsy or exposure to ionizing radiation via measurement of bone mineral density. of

such as muscle biopsy or exposure to ionizing radiation via measurement of bone mineral density. Many studies therefore use performance and functional outcomes as proxies for physiological adaptations.

So while we cannot directly infer tissue-level adaptation from these results, it does add useful information with respect to program design.

We will review the data that do exist for youth athletes and point out when our understanding is extrapolated from data in the adult population.

For the Global effects on Resistance Training, Teshara et al reviewed the effects of

skeletal muscle loading on skeletal muscle repair.

While there were not specific dosage parameters given for what constitutes quote-unquote loading, we can begin

to distinguish the effects of loading versus inactivity in more general terms.

The above figure from Clark and Skeba demonstrates the response to resistance training. Different forms of stimuli elicit different tissue adaptations.

While increasing V.O2 max may be a positive training effect for swimming,
