Five reps of weight 60 to 80% 1-RM
was performed as a further warm-up, then rating of perceived exertion (RPE) was recorded that was followed by a 2-min rest period.
The exercise protocol was done 1 week after the 1-RM
The loads used during training were determined during 1-RM
testing (explained in detail below) and remained consistent throughout the training program, with progressive overload achieved via increases in the number of repetitions performed to failure.
(30) Segundo Urso e colaboradores, (31) o treinamento de forca em idosos com e sem presenca de VCI implementado com frequencia de 30 Hz (2-4 mm), 2 vezes por semana durante 10 semanas com o individuo em semiflexao de joelhos proporciona desempenho semelhante no teste de 1-RM
entre os grupos intervencao e controle.
was estimated according to the regression equation of Brzycki .
This subjective feeling of exertion may also lead the obese group to train against a lower resistance - since the 1-RM
is to a certain extent underpinned by the perceived exertion.
Recommendations for the implementation of strength training advise that people with stroke work at an intensity of 50-80% of their 1-RM
. This represents a moderate to high intensity of effort; the person should only be able to complete 8 to 14 repetitions of an exercise before they experience volitional fatigue.
All subjects were tested for unilateral one repetition maximum (1-RM
) dynamic constant external resistance (DCER) strength of the dominant (based on throwing preference) forearm flexors while seated in a chair.
At the initial session, the Mayhew regression equation was used to safely predict the one-repetition maximum (1-RM
) for all five CRT exercises while performing sub-maximal lifting (Figure 1) .
However, no significant differences were observed between groups in anabolic or catabolic hormone status, body composition, 1-RM
bench press and leg press, upper or lower body muscular endurance, or cycling anaerobic capacity.
Strength training promotes neuromuscular adaptations which are dependent of the intensity relative to maximum load (% of 1-RM
) at which the training is performed.
(2006b) assessed elderly women submitted to resistance training for 16 weeks (4 weeks at 50% 1-RM
and 12 weeks at 75-85% 1-RM
), obtaining significant increases in muscle strength and range of joint motion, in addition to improved performance on the 10MW and RSP tests.
