Grip power test: A new valid and reliable method for assessing muscle power in healthy adolescents

Abstract

The assessment of the strength and muscle mass of the hand-finger segment are reliable indicators of health and predictors of cardiometabolic risk in the adult population. However, there are no valid and reliable tests to assess the muscle power of this segment in healthy adolescents. The objective of this study was to determine the validity and inter-day reliability of a grip power test (GripW test) in healthy adolescents. Twenty-one adolescents (15.61 ± 2.20 years old) were part of the study. All participants were instructed to perform a grip with incremental load sets from 1–10 kg as fast as possible. The validity of the GripW test was determined with the load-power curve and linear regression equation. Inter-day reliability considered the coefficient of variation (CV), intra-class correlation coefficient (ICC), and standard error of the mean (SEM). The significance level for all statistical analyses was p < 0.05. The parabola in the load-power curve for both hands showed normality for the GripW test. In addition, the analysis showed a CV = 4.63% and ICC = 1.00 for the right hand, while the left hand showed a CV = 3.23% and ICC = 1.00. The GripW test proved to be valid and reliable for assessing gripping muscle power functionally and unilaterally in healthy adolescents.

“…Además, una identificación temprana deficiente de MQ en esta etapa de la vida puede permitir la implementación de intervenciones preventivas que ayuden a los adolescentes a alcanzar su máximo potencial de salud y bienestar a medida que avanzan hacia la edad adulta (Barahona-Fuentes et al, 2023;Delgado-Floody et al, 2023). Desafortunadamente, y pese a que los estudios demuestran la importancia calidad muscular en la población (Barahona-Fuentes et al, 2023;Barbat-Artigas et al, 2012;Delgado-Floody et al, 2023;Jerez-Mayorga et al, 2019;Reyes-Ferrada et al, 2022), estas evaluaciones en su amplio espectro han utilizados valoraciones poco congruentes (Huerta Ojeda et al, 2021). En este sentido, los diferentes estudios que han determinado MQ independiente de la población, han evaluado por ejemplo los niveles de fuerza a través de la fuerza prensil que involucra musculatura flexora del (Bohannon, 2015), mientras que para evaluar potencia lo han hecho con test de otros grupos musculares como puede ser un press banca (Clemons et al, 2010), mientras que para tamaño muscular lo han hecho con la composición de masa muscular global del sujeto (Reyes-Ferrada et al, 2022).…”

An experimental study on the influence of healthy physical education curriculum model on sports ability of Chinese senior high school students

“…The muscle strength test includes two indicators: upper limb muscle strength, measured by grip strength [ 21 ], and lower limb muscle strength, measured by standing long jump [ 22 ]. For the grip strength test, the subject stands upright with their feet shoulder-width apart, arms hanging down, and palms facing inward.…”

“…All participants received verbal support during the execution of the test. The best result from several trials for each hand is recorded ( 20 , 21 ). We use a numerical rating system to classify the hand grip strength, with 5 denoting excellent, 4 good, 3 regular, 2 poor, and 1 very poor hand grip strength as shown in Table 2 ( 23 ).…”
