Karma Power: 29 | forced reps = grotere hormoonaanmaak
Acute hormonal and neuromuscular responses and recovery to forced vs maximum repetitions multiple resistance exercises. Ahtiainen JP, Pakarinen A, Kraemer WJ, Hakkinen K. Department of Biology of Physical Activity, University of Jyvaskyla, Jyvaskyla, Finland. ahtiainen@sport.jyu.fi Acute hormonal and neuromuscular responses and recovery three days after the exercises were examined during the maximum repetitions (MR) and forced repetitions (FR) resistance exercise protocols in 16 male athletes. MR included 4 sets of leg presses, 2 sets of squats and 2 sets of knee extensions (with 12 RM) with a 2-min recovery between the sets and 4 min between the exercises. In FR the initial load was chosen to be higher than in MR so that the subject could not lift 12 repetitions per set by himself. After each set to failure the subject was assisted to perform the remaining repetitions to complete the 12 repetitions per set. Thus the exercise intensity was greater in FR than in MR. Both loading protocols led to the great acute increases (p < 0.05 - 0.001) in serum testosterone, free testosterone, cortisol and GH concentrations. However, the responses in cortisol (p < 0.05) and GH (p < 0.01) were larger in FR than in MR. The decrease of 56.5 % (p < 0.001) in maximal isometric force in FR was greater (p < 0.001) than that of 38.3 % in MR (p < 0.001) and force remained lower (p < 0.01) during the recovery in FR compared to MR. The larger decrease in isometric strength in FR than in MR was also associated with the decreased maximal voluntary EMG of the loaded muscles. The data indicate that the forced repetition exercise system induced greater acute hormonal and neuromuscular responses than a traditional maximum repetition exercise system and therefore it may be used to manipulate acute resistance exercise variables in athletes.

forced reps zou je toch ook kunnen vergelijken met dropsets?

Citaat:
Een spotter kan precies zien wanneer je het echt niet lukt en jouw toch het meeste werk laten doen om je rep af te maken. Zo zal de intensiteit bijna altijd hoger zijn dan bij DS.

huh en ik dacht dat till failure en daar overheen gaan niet veel nut had, noujah de wonderen zijn de wereld blijkbaar nog niet uit!

Ten eerste de FR groep gebruikt hogere gewichten dus daar kan het ook door komen. Overigens stijgt de test in beide groepen evenveel. En de FR groep produceert meer cortisol. En een nadeel van forced reps is dat ze heel zwaar zijn voor het CZS, dus ga je er sneller op overtrainen. En die extra stijging in GH zou je bijv ook door HIIT cardio kunnen bereiken, wat het CZS niet zo hoog belast.
