Hand Grip Strength

Research Review: Linking Hand Grip Strength and Cognitive Impairment

McGrath R, et al. (2019) The Longitudinal Associations of Handgrip Strength and Cognitive Function in Aging Americans. J Am Med Dir Assoc Nov 6. pii: S1525-8610(19)30649-8. doi: 10.1016/j.jamda.2019.08.032. [Epub ahead of print] Introduction While muscle weakness associates with a variety of poor health outcomes including morbidity, functional limitations, and early mortality, emerging evidence suggests that…

Blood Flow Restriction for Strength Training in Older Adults without High Loads

Research Review: Blood Flow Restriction Allows for Strength Training in Older Adults without Requiring High Loads

Centner C, et al. (2019) Effects of blood flow restriction training on muscular strength and hypertrophy in older individuals: A systematic review and meta-analysis. Sports Med;49:95-108. Introduction Applying tourniquets or inflatable cuffs at the proximal portion of a limb–referred to as blood-flow restriction (BFR)– during low-load (LL) [20-to-30% of one repetition maximum (1RM) resistance training…

How Muscles Work (Part 2 of 2)

This is the second of a two part series explaining how muscles work. In this first article we describe the gross structure of skeletal muscle; in the second article I describe skeletal muscle ultrastructure and how muscles develop tension. Skeletal Muscle Ultrastructure Highly technical and sophisticated techniques that include electron microscopy, x-ray diffraction, histochemical staining,…

Strength Tracking Sensor Performance Validated Against More Expensive Solutions

New strength training research was presented on Friday July 12th at the NSCA national conference in Washington DC. Research from the University of Toledo compared the accuracy of ShapeLog’s low-cost retrofit sensor with the isokinetic Biodex device found in human performance labs around the globe. Data from ShapeLog’s portable, retrofit device was compared to data…

How Muscles Work (Part 1 of 2)

This is the first of a two part series explaining how muscles work. In this first article I describe the gross structure of skeletal muscle; in the second article I describe skeletal muscle ultrastructure and how muscles develop tension. Gross Structure of Skeletal Muscle Humans possess three types of muscle—cardiac, smooth, and skeletal—each exhibiting distinct…

Research Review: Comparing Free Weights and Machine Training for Older Adults

Schott N, et al. Effects of free weights and machine training on muscular strength in high-functioning older adults. Exp. Gerontology. Vol. 122;15-24. 2019. Introduction The decrease of muscle mass (sarcopenia), strength and muscular power (dynapenia) are physiological processes of aging, in particular with the onset of the sixth decade. There is ample evidence that resistance…

Comparison: Force Profile from Weights vs Resistance Bands

The most common way to train for strength is to use weights, and whether you use free weights or selectorized weight stack machines the experience felt by the body is similar. Moving a fixed mass against the force of gravity is a familiar routine to our muscles. After all, this phenomenon happens every time we…

Research Review: Greater Training Frequency = Greater Training Volume = Greater Strength Gains

Grgic J, Schoenfeld BJ, Davies TB, et al. Effect of Resistance Training Frequency on Gains in Muscular Strength: A Systematic Review and Meta-Analysis. Sports Med. Vol. 48, pp. 1207-1220, 2018. Introduction Muscular strength defines as the capacity to exert force under a particular set of biomechanical conditions. Engaging in resistance training (RT) can significantly increase…

Measuring Force with ShapeLog’s ShapeSense Select

I have had long conversations about ShapeLog’s ShapeSense Select (Select) only to later realize that an important feature (THE most important feature, really) is not understood. The sensor doesn’t just measure motion. It also measures force! When the Select is slipped onto a cable or belt an arm on the UST redirects the cable such…
