Force Production Measurements During a Supine Medicine Ball Throw: a Reliability and Correlation Study.

Objectives: This study aimed to examine the reliability of supine medicine ball throw peak force and rate of force development (RFD) measurements. A secondary aim was to investigate the correlations between these measurements and vertical jump height.

Methods: Twenty young women (21±3 years) reported for experimental testing on two different occasions.

Reliability of handgrip strength measurements and their relationship with muscle power.

Background: Handgrip peak force and rate of force development (RFD) have been shown to be useful measurements at characterizing the strength capacities of numerous muscle groups, including those of the lower extremities. However, the reliability of these measurements and their relationship with peak muscle power remain uncertain. We aimed to examine the reliability of handgrip peak force and RFD measurements.

Can handgrip strength measurements predict postural balance performance in older women?

Objectives: The link between handgrip strength and postural balance in older adults is not well understood. This study aimed to examine the correlations between postural balance performance and handgrip peak force and rate of force development (RFD) measurements in older women.

Methods: Twenty older women (67 ± 5 years) participated in this study.
