Activación unidades motoras por EMGimax

[KaS]

Si, hay ejercicios que faltan efectivamente, en pectoral tampoco salen los fondos y debe ser de los que mas unidades motoras activan.

Que faltan, o que tenemos sobrevalorados.....en segun que casos para segun que musculos...

A lo mejor es ese que se llama "flexiones de brazos entre bancos", que a veces las traducciones...

[KaS]

No creo q sea ese q dices, el q comentas tu son flexiones entre bancos q al quedar elevado puedes descender mas el cuerpo que cuando lo haces sobre el suelo.

Aqui dejo las conclusiones de dos estudios sobre los remos:

Estudio: Comparison Of Different Rowing Exercises: Trunk Muscle Activation And Lumbar Spine Motion, Load, And Stiffness, by Fenwick, Brown, and McGill, in Journal of Strength and Conditioning Research, 2009

Conclusiones:
- For targeting the lats and upper back, the inverted row is superior to the bent-over row. However, the bent-over row produces greater overall back muscle activity, including the lower back, and challenges spinal stability the most.
- The bent-over row creates large compressive forces and flexion/extension movements, while the one-arm row produces large rotational movements. The inverted row does not cause the same relative movements or involve the same forces. The inverted row may therefore be better suited for those with lower back trouble.


Estudio: Variations in muscle activation levels during traditional latissimus dorsi weight training exercises: An experimental study. By Lehman, Buchan, Lundy, Myers and Nalborczyk, in Dynamic Medicine, 2004

Conclusiones:
- Pronated and supinated pull-downs (and possibly also therefore chins and pull-ups) only differ slightly in respect of the relative activity of the latissimus and biceps muscles. These differences are therefore unlikely to make a significant difference to the beginner or intermediate trainee.
- Seated rows produce greater latissimus dorsi and middle trapezius/rhomboid activity than pull-downs of any kind.
- Seated rows tend to produce greater latissimus dorsi and middle trapezius/rhomboid activity when performed with scapular retraction.
