Abstract

Iglesias, E, Boullosa, DA, Dopico, X, and Carballeira, E. Análisis of factors that influence the maximum number of repetitions in two upper-body resistance exercises: curl biceps and bench press. J Strength Cond Res 24(6): 1566-1572, 2010-The purpose of this study was to analyze the influence of exercise type, set configuration, and relative intensity load on relationship between 1 repetition maximum (1RM) and maximum number of repetitions (MNR). Thirteen male subjects, experienced in resistance training, were tested in bench press and biceps curl for 1RM, MNR at 90% of 1RM with cluster set configuration (rest of 30s between repetitions) and MNR at 70% of 1RM with traditional set configuration (no rest between repetitions). A lineal encoder was used for measuring displacement of load. Analysis of variance analysis revealed a significant effect of load (p < 0.01) and a tendency in exercise factor (p = 0.096), whereas the interaction effect was not significant. MNR at 70% of 1RM was lower for biceps curl (16.31 +/- 2.59 vs. 8.77 +/- 3 in bench press and biceps curl, respectively; p < 0.05) and at 90% of 1RM (21.85 +/- 11.06 vs. 18.54 +/- 12.84 in bench press and biceps curl, respectively; p > 0.05). Correlation between 1RM and MNR was significant for medium-intensity in biceps curl (r = -0.574; p < 0.05) and between MNR and 1RM/body mass (r = -0.574; p < 0.05). Neither 1RM nor 1RM/body mass correlated with velocity along set, so velocity seems to be similar at a same relative intensity for subjects with differences in maximum strength levels. From our results, we suggest the employment of MNR rather than % of 1RM for training monitoring. Furthermore, we suggest the introduction of cluster set configuration for upper-body assessment of MNR and for upper-body muscular endurance training at high-intensity loads, as it seems an efficient approach in looking for sessions with greater training volumes. This could be an interesting approach for such sports as wrestling or weightlifting.​

הקטע של ה30 שניות מנוחה די דפק את המחקר הזה לדעתי...
הרי ממה שאני הבנתי אין לזה משמעות מיוחדת ואולי אם היו נותנים להם כמה זמן שהם צריכים בין סט לסט, כמו שווייטליפטרים אמיתיים עושים - התוצאה של המחקר הייתה אחרת?

כן, אבל צריך לקרוא את המלא כדי לקבל עוד מסקנות
