Relationship between Dynamic and Isometric Strength, Power, Speed, and Average Propulsive Speed of Recreational Athletes

Abstract

The purpose of this study was to examine the type of relationship between measures of maximal force (dynamic and isometric), maximal power, and mean propulsive velocity. In total, 355 recreational athletes, 96 women (age 20.5 ± 2.5 years; height 158.2 ± 17.3 cm; weight 61.8 ± 48.4 kg) and 259 men (age 21.0 ± 2.6 years; height 170.5 ± 12.6 cm; weight 65.9 ± 9.2 kg) were evaluated in three sessions separated by 72 h each in isometric midthigh pull exercise (ISOS) (kg), bench press maximum strength (1RM MSBP) (kg), jump height (CMJ) (m), and maximum pedaling power (WT) the maximum squat strength (1RM MSS) (kg), the mean propulsive velocity in the bench press (MPVBP) (m·s−1), and the peak power (PPBP) (w), mean propulsive squat velocity (MPVS) (m·s−1), peak power (PP) (w), maximum handgrip force (ISOHG) (kg), and 30 m movement speed (V30) (s). Significant correlations (p ≤ 0.01) were identified between 95% of the various manifestations of force, and only 5% presented a significance of p ≤ 0.05; however, when the magnitude of these correlations is observed, there is great heterogeneity. In this sense, the dynamic strength tests present the best correlations with the other strength and power tests used in the present study, followed by PPBP and PP. The results of this study complement what is reported in the literature regarding the correlation between different types of force manifestations being heterogeneous and contradictory.

Different Body Partialization Procedures Considering Maximum Strength and Explosiveness: Factorial Analysis Approach

“…Andersen & Aagaard (2006) showed in their study that the force in maximal voluntary contraction (MVC) is strongly related to RFD in the late phase, so factors such as muscle length and architecture can influence RFD (Maffiuletti et al, 2016). Also, recently published research where dynamic and isometric tests are compared showed a moderate to strong statistical correlation between those two contractile work regimes, where is suggested that isometric force-time characteristics (RFD max ) provide insights into the rapid force production capability of human subjects which give acumen into dynamic performance capabilities (Lum et al, 2020;Ferná Ortega et al, 2022).…”
