I did the following workouts over the past week. I did legs/abs at Fike Gym and Back/Chest/Neck at UE.
3/31 at Fike: Calf Press, Leg Extension (full extension from 3rd rep on), Leg Curl, Hammer Leg Press, Hammer Clam Shell Abdominal
4/06 at UE: SS Systems Pulldown, MedX Chest Press (horizontal handles), SS Systems Neck Flexion, Nautilus Pullover with SS retrofits, MedX Chest Press (vertical handles), MedX Row with SS cam, SS Systems Neck Extension.
Both workouts were great. I recovered well despite a very hectic week in the ER.
There has been much debate in the past about whether resistance training significantly affects hormonal profiles as it pertains to muscle growth. There is little evidence to show that increases in sex steroids or growth hormone are contributing factors to the growth mechanism. However, recent research does indicate that resistance training does improve overall hormonal profiles as the relate to general health and sexual function. This recent study shows that resistance training can restore the activity of enzymes involved in sex steroid synthesis, and ultimately testosterone levels in older male subjects. Activity levels were restored to youthful levels in this study.
The problem with T supplementation or drugs for erectile dysfunction is that the thought process is like pushing with a rope. Rather than trying to create the right conditions for the end product, you just supply the end product. The problem is that the end product is part of a feedback loop; when you supply it exogenously, you further inhibit production. With resistance exercise you are create the proper stimulus to require the desired end-product, thus keeping both sides of the feedback loop stimulated and balanced. You get the end product as a result of stimulated production rather than as a supplied entity that shuts down production.
Resistance training restores muscle sex steroid hormone steroidogenesis in older men.
Skeletal muscle can synthesize testosterone and 5α-dihydrotestosterone (DHT) from dehydroepiandrosterone (DHEA) via steroidogenic enzymes in vitro, but hormone levels and steroidogenic enzyme expression decline with aging. Resistance exercise has been shown to increase in plasma sex steroid hormone levels. However, it remains unclear whether resistance training can restore impaired steroidogenic enzyme expressions in older individuals. Six young and 13 older men were recruited, and muscle biopsies were taken from the vastus lateralis at basal state. The same group of older subjects underwent resistance training involving knee extension and flexion exercises for 12 wk, and post-training biopsies were performed 4-5 d after the last exercise session. Muscular sex steroid hormone levels and sex steroidgenesis-related enzyme expressions were significantly lower in older subjects than younger ones at baseline, but 12 wk of resistance training significantly restored hormone levels (DHEA: 432±26 at baseline, 682±31 pg/μg protein, DHT: 6.2±0.9 at baseline, 9.8±1.4 pg/μg protein). Furthermore, the steroidogenesis-related enzymes such as 3β-hydroxysteroid dehydrogenase (HSD), 17β-HSD, and 5α-reductase expressions were significantly restored by resistance training. We conclude progressive resistance training restores age-related declines in sex steroidogenic enzyme and muscle sex steroid hormone levels in older men.-Sato, K., Iemitsu, M., Matsutani, K., Kurihara, T., Hamaoka, T., Fujita, S.
