A Polygenic Risk Score for Hand Grip Strength Predicts Muscle Strength and Proximal and Distal Functional Outcomes among Older Women

2022

Purpose Hand grip strength (HGS) is a widely used indicator of overall muscle strength and general health. We computed a polygenic risk score (PRS) for HGS, and examined, whether it predicted muscle strength, functional capacity and disability outcomes. Methods Genome-wide association study summary statistics for HGS from the Pan-UK Biobank was utilized. PRSs were calculated in the Finnish Twin Study on Aging (N = 429 women, 63–76 years). Strength tests included HGS, isometric knee extension, and ankle plantar flexion strength. Functional capacity was examined with the Timed Up and Go, six-minute and 10-meter walk tests, and dual-task tests. Disabilities in the basic (ADL) and instrumental …

Effects of aging and training on sprint performance, muscle structure and contractile function in athletes

2009

Cross-sectional studies were conducted to examine sprint running, anaerobic energy production and muscle properties in male sprinters aged 17-88 years. In addition, a 20-week training intervention was carried out to determine whether older runners can further improve their neuromuscular and performance characteristics by a greater emphasis on strength training. With age, sprint performance declined gradually (5-6%/decade). The slowing of maximum speed was characterized by a reduction in stride length and an increase in contact time along with lower ground reaction forces (GRF) and smaller leg and vertical stiffness during the contact phase. Stride frequency showed small decline while swing …

Effects of hormonal contraceptives on physical performance and body composition

2016

The purpose of the present study was to examine the effects of hormonal contraceptive use on neuromuscular, cardiorespiratory and body composition adaptations following combined strength and endurance training period. Methods. Nineteen recreationally active women; 11 who had at least one year of hormonal contraceptive use (age 294 yr; BMI 212 kg/m2; VO2max 444 ml/kg/min) and 8 who had never used hormonal contraceptives (age 315 yr; BMI 222 kg/m2; VO2max 414 ml/kg/min) participated in the present study of combined strength and endurance training for 10 weeks. Training consisted of two maximal and explosive strength training sessions, and two high-intensity interval training sessions pe…

Effects of Task-Specific and Strength Training on Simulated Military Task Performance in Soldiers.

2020

A soldier’s occupational physical task requirements are diverse and varied. However, the type of physical training that most effectively improves soldiers’ occupational task requirements has not been studied previously. The purpose of this study was to determine the important strength characteristics for soldiers during a repeated simulated military task course, and the type of training that may be effective to improve these abilities during a specialized military training period. Forty-two (n = 42) soldiers participated in the study. They were divided into three training groups; a soldier task-specific training group (TSG, n = 17), a strength training group (STG, n = 15), and a control gro…

Acute neuromuscular and hormonal responses to 20 versus 40% velocity loss in males and females before and after 8 weeks of velocity-loss resistance t…

2022

Scientific examination of velocity-based resistance training (VBRT) has increased recently, but how males and females respond to different VBRT protocols or how these acute responses are modified after a period of training is unknown. Habitually resistance-trained males and females followed either a 20 or 40% velocity-loss programme for 8 weeks. Acute squat loading tests (five sets, 70% one-repetition maximum load, 3 min rest) were performed before and after the training period. Tests of maximum neuromuscular performance and blood sampling were conducted before, within 10 min of completion (POST) and 24 h after each acute loading test. Testing included countermovement jump, resting femoral …

Proximity Effect in Superconducting Heterostructures with Strong Spin-Orbit Coupling and Spin Splitting

2019

It has been shown that singlet Cooper pairs can be converted into triplet ones and diffuse into a ferromagnet over a long distance in a phenomenon known as the long-range proximity effect (LRPE). This happens in materials with inhomogeneous magnetism or spin-orbit coupling (SOC). Most of the previous studies focus on the cases with small SOC and exchange field. However, the physics was not clear when SOC and exchange field strength are both much greater than the disorder strength. In this work, we consider a two dimensional system with a large Rashba-type SOC and exchange field in the case where only one band is partially occupied. We develop a generalized quasiclassical theory by projectin…

Effects of Temperature and Humidity on Radio Signal Strength in Outdoor Wireless Sensor Networks

2015

Many wireless sensor networks operating outdoors are exposed to changing weather conditions, which may cause severe degradation in system performance. Therefore, it is essential to explore the factors affecting radio link quality in order to mitigate their impact and to adapt to varying conditions. In this paper, we study the effects of temperature and humidity on radio signal strength in outdoor wireless sensor networks. Experimental measurements were performed using Atmel ZigBit 2.4GHz wireless modules, both in summer and wintertime. We employed all the radio channels specified by IEEE 802.15.4 for 2.4GHz ISM frequency band with two transmit power levels. The results show that changes in …
