The Relationship Between the Number of Repetitions Performed at Given Intensities Is Different in Endurance and Strength Trained Athletes

Abstract

Prescribing training intensity and volume is a key problem when designing resistance training programmes. One approach is to base training prescription on the number of repetitions performed at a given percentage of repetition maximum due to the correlation found between these two measures. However, previous research has raised questions as to the accuracy of this method, as the repetitions completed at different percentages of 1RM can differ based upon the characteristics of the athlete. The objective of this study was therefore to evaluate the effect of an athlete's training background on the relationship between the load lifted (as a percentage of one repetition maximum) and the number of repetitions achieved. Eight weightlifters and eight endurance runners each completed a one repetition maximum test on the leg press and completed repetitions to fatigue at 90, 80 and 70% of their one repetition maximum. The endurance runners completed significantly more repetitions than the weightlifters at 70% (39.9 ± 17.6 versus 17.9 ± 2.8; p < 0.05) and 80% (19.8 ± 6.4 versus 11.8 ± 2.7; p < 0.05) of their one repetition maximum but not at 90% (10.8 ± 3.9 versus 7.0 ± 2.1; p > 0.05) of one repetition maximum. These differences could be explained by the contrasting training adaptations demanded by each sport. This study suggests that traditional guidelines may underestimate the potential number of repetitions that can be completed at a given percentage of 1RM, particularly for endurance trained athletes.

Velocity Loss as a Variable for Monitoring Resistance Exercise

“…However, some research has found that the number of repetitions completed showed a positive relationship with the number of capillaries per mm 2 of muscle cross-sectional area [28], and a negative correlation with the percentage of type II fibers [5]. Therefore, it appears that the large variability observed in the number of repetitions completed against a given load ( %1RM) may depend, at least in part, on the specific muscle characteristics and training background of each participant [21].…”

Número Mínimo De Repetições Para Redução Na Força Máxima No Exercício Rosca Scott

“…Neste estudo os autores verificaram que levantadores de peso executaram menos repetições até a exaustão com as intensidades de 70 e 80% de 1-RM, no exercício leg press, do que corredores, que possuem uma força máxima em torno de 50% menor do que os levantadores de peso. [9] Esse achado pode ser parcialmente explicado pela variação da força máxima entre nossos voluntários, os quais apresentaram cargas para o teste de 1-RM entre 64,0 kg (máximo) e 30 kg (mínimo) . Apesar de todos serem habituados ao TR, sujeitos mais fortes podem ter realizado mais testes e treinos com cargas próximas a máxima, o que os coloca em melhores condições de atingirem altos níveis de força, fazendo com que a carga absoluta utilizada no teste de repetição máxima fosse estressante em função de serem mais familiarizados a testes de força máxima, levando, consequentemente a uma exaustão antecipada.…”

Study of training for improving lip incompetence

“…It has been reported that hypoxic muscle training is effective for improving muscle strength and that aerobic muscle training is effective for improving muscle endurance [9]. On the other hand, Kon et al…”

“…On the other hand, aerobic exercise, which is training under a condition with a high oxygen concentration in muscle, is effective for increasing the endurance of muscles, which is persistence of muscle activity [9].…”
