ITT: We post links to research journals and articles for weight training

[sawoobley]

I haven't really looked into the science of weight training but I went on a tangent tonight and found some cool stuff. Anyone have anything to add?

The Effect of Back Squat Depth on the EMG Activity of 4 Superficial Hip and Thigh Muscles (full article)
http://edulife.com.br/dados%5CArtigos%5CEducacao%20Fisica%5CMuscula%C3%A 7%C3%A3o%20e%20Condicionamento%20Fisico%5CThe%20Ef fect%20of%20Back%20Squat%20Depth%20on%20the%20EMG. pdf

The primary difference appears to be in the EMG activity of the Gluteus Maximus among these 3 squatting depths.


The effect of back squat depth on the EMG activity of 4 superficial hip and thigh muscles. (abstract)
http://www.ncbi.nlm.nih.gov/pubmed/12173958

The results suggest that the Gluteus Maximus, rather than the BF, the VMO, or the VL, becomes more active in concentric contraction as squat depth increases.



The effect of stance width on the electromyographical activity of eight superficial thigh muscles during back squat with different bar loads
http://www.ncbi.nlm.nih.gov/pubmed/19130646

These findings suggest that a large width is necessary for a greater activation of the gluteus maximus during back squats.



A comparison of muscle activation between a Smith machine and free weight bench press
http://www.ncbi.nlm.nih.gov/pubmed?term=20093960 (abstract - 2010 article)
http://www.castonline.ilstu.edu/mccaw/hpr482/EMGREAD_files/4065%20mccaw%20%26%20friday%20bench%20press.pdf (similar full-text older article)

The results of this study suggest that strength coaches should consider choosing the free weight bench press over the Smith machine bench press because of its potential for greater upper-body muscular development.

This isn't part of the peer-reviewed article side of things, but http://benbruno.blogspot.com/ is worth noting because of how many blogs and videos he links each week. I've known of him through a few forums and he is a good guy...but seriously, if you want something training related to watch or read (again, more opinion based rather than studies), there is a lot to find in the good reads and for your viewing pleasure posts.

Good thread! My studies aren't very well organised, however. But I'll try find what I can.



The Influence of Frequency, Intensity, Volume and Mode of Strength Training on Whole Muscle Cross-Sectional Area in Humans

Applications of the dose-response for muscular strength development: a review of meta-analytic efficacy and reliability for designing training prescription.
http://www.ncbi.nlm.nih.gov/pubmed/16287373

This study suggests that higher frequency is superior for strength gains.

Differential effects of strength training leading to failure versus not to failure on hormonal responses, strength, and muscle power gains.
http://www.ncbi.nlm.nih.gov/pubmed/16410373?dopt=Abstract

This study shows not training to failure resulted in better strength gains, but sets to failure resulted in better muscular endurance.


Effect of short-term failure versus nonfailure training on lower body muscular endurance.
http://www.ncbi.nlm.nih.gov/pubmed/19211941

"These results indicate that when intensity and volume are equated, failure or nonfailure training results in similar gains in lower body muscular endurance."

" There was no significant difference between 2-3 sets per exercise and 4-6 sets per exercise"


Effects of Variations of the Bench Press Exercise on the EMG Activity of Five Shoulder Muscles
http://journals.lww.com/nsca-jscr/Abstract/1995/11000/Effects_of_Variations_of_the_Bench_Press_Exercise. 3.aspx

" the clavicular head of the pectoralis major was no more active during the incline bench press than during the horizontal one, but it was less active during the decline bench press."

No probs.

Anyone else?

Is this where the science is?

For people who are more into pushing heavy weights:
"Clemons, J. M., & Aaron, C. (1997) examined the difference in muscle activity (using an electromyographic, EMG Biopak system) during the concentric phase when width of grip was varied during the flat bench press. Four grip widths of 100%, 130%, 165% and 190% (G1, 2, 3, and 4 respectively) of biacromial width (shoulder width as defined by the distance between acromion processes) were investigated. Mean integrated myoelectric (MiEMG) activity for each muscle was normalized to max volitional isometric contractions (%MVIC). Specific muscles studied were the pectoralis major, anterior deltoids, triceps brachii, and biceps brachii.

The results showed that there were significant differences between G1 and G2 with G4. The G4 grip produced maximum %MVIC for the collective set of prime movers. %MVIC for prime movers in ascending order was the biceps brachii followed by the pectoralis major, anterior deltoid, and the triceps brachii.

There was no significant change in muscle interaction for change in grip width. This is contradicted by other research. However, the results clearly showed that the G4 grip is the best grip since it produced maximum activity in prime movers. The authors suggest that if the G4 grip does not feel comfortable for the lifter, a width between G3 and G4 should be used for good bench press performance."

Thanks for these!


Will definitely come in handy both in the forums and with my friends :D
