Maximum Dynamic Lower-Limb Strength Was Maintained During 24-Week Reduced Training Frequency in Previously Sedentary Older Women.

2018

Walker, S, Serrano, J, and Van Roie, E. Maximum dynamic lower-limb strength was maintained during 24-week reduced training frequency in previously sedentary older women. J Strength Cond Res 32(4): 1063-1071, 2018-There is little study into the effects of reducing strength training below the recommended twice weekly frequency, particularly in older women, despite the possibility that individuals will encounter periods of reduced training frequency. The purpose of the present study was to determine the effects of a period of reduced training frequency on maximum strength and muscle mass of the lower limbs in comparison with the recommended training frequency of twice per week. After an initia…

Safety, Fear and Neuromuscular Responses after a Resisted Knee Extension Performed to Failure in Patients with Severe Haemophilia

2021

BACKGROUND: low-moderate intensity strength training to failure increases strength and muscle hypertrophy in healthy people. However, no study assessed the safety and neuromuscular response of training to failure in people with severe haemophilia (PWH). The purpose of the study was to analyse neuromuscular responses, fear of movement, and possible adverse effects in PWH, after knee extensions to failure.METHODS: twelve severe PWH in prophylactic treatment performed knee extensions until failure at an intensity of five on the Borg CR10 scale. Normalised values of amplitude (nRMS) and neuromuscular fatigue were determined using surface electromyography for the rectus femoris, vastus medialis,…

Muscle cramping in the marathon: dehydration and electrolyte depletion vs. muscle damage

2020

Martinez-Navarro, I, Montoya-Vieco, A, Collado, E, Hernando, B, Panizo, N, and Hernando, C. Muscle Cramping in the marathon: Dehydration and electrolyte depletion vs. muscle damage. J Strength Cond Res XX(X): 000-000, 2020-Our aim was to compare dehydration variables, serum electrolytes, and muscle damage serum markers between runners who suffered exercise-associated muscle cramps (EAMC) and runners who did not suffer EAMC in a road marathon. We were also interested in analyzing race pacing and training background. Nighty-eight marathoners took part in the study. Subjects were subjected to a cardiopulmonary exercise test. Before and after the race, blood and urine samples were collected and…

Dietary intake and strength training adaptation in 50-70 -year old men and women : with special reference to muscle mass, strength, serum anabolic ho…

2007

Frailty has been defined as an age-related decrease of the physiologic systems that results in weakness, weight loss and decreased functional performance, thus increasing the risk of disability. The physical characteristics of frailty are affected by the amount of muscle mass and strength. Strength training (ST) can alleviate age-related declines in muscle mass, strength and physical function. However, there is controversy regarding whether dietary intake can improve the effects of ST. The present thesis assessed the effects of dietary intake (DI) on muscular, hormonal and metabolic adaptations to ST in healthy 50-70 year old people. In cross-sectional study I, maximal strength of the leg e…

Effects of internal kinetics and muscle activity during the wide and narrow barbell back squat

2017

Lahti, J. 2017. Effects of internal kinetics and muscle activity during the wide and narrow barbell back squat. Sports biology department, University of Jyväskylä. Master’s thesis. p. 102 (4 attachments). Introduction. The barbell back squat (BBS) is a commonly utilized strength exercise to support general preparedness for the demands in multiple sports. Recently, studies have shown various strength training exercises have the potential to recruit the regions of the hamstrings differently. Specifically, it is unknown if changing stance width under conditions where forward knee movement is restricted engages the hamstring regions differently and how this corresponds with measured 3-D net joi…

Physical fitness, pain and fatigue in postmenopausal women with fibromyalgia : effects of strength training

2007

Fibromyalgia (FM) is a chronic non-inflammatory pain syndrome characterized mainly by widespread pain, fatigue and sleep disturbance. Its pathophysiology is still unknown and no curative treatment exists. Exercise training is usually recommended to persons with FM as one part of the treatment program; however, strength training has been studied very seldom in persons with FM.The purpose of this thesis was 1) to compare neuromuscular and aerobic performance, functional capacity, pain and fatigue between postmenopausal women with fibromyalgia (FMW) and healthy women (HW) and 2) to examine the acute responses of heavy resistance fatiguing loading and the effects of regular strength training on…

Decreasing muscle performance associated with increasing disease activity in patients with rheumatoid arthritis

2018

Objectives Increasing evidence suggests that inflammation has a detrimental effect on muscle strength. Our objective was to analyse the association between muscle performance and different disease activity levels in patients with rheumatoid arthritis (RA). Method A total of 199 consecutive outpatients were subject to cross-sectional assessment. Measurements of grip strength, endurance of the upper and lower limbs and trunk strength were combined as a muscle performance composite score (MPCS), using a standardised method. The disease activity for 28 joints (DAS28), radiographs of small joints (Larsen score), rheumatoid factor, body mass index (BMI), comorbidities and anti-rheumatic drugs wer…

Information Extraction from Binary Skill Assessment Data with Machine Learning

2021

Strength training exercises are essential for rehabilitation, improving our health as well as in sports. For optimal and safe training, educators and trainers in the industry should comprehend exercise form or technique. Currently, there is a lack of tools measuring in-depth skills of strength training experts. In this study, we investigate how data mining methods can be used to identify novel and useful skill patterns from a binary multiple choice questionnaire test designed to measure the knowledge level of strength training experts. A skill test assessing exercise technique expertise and comprehension was answered by 507 fitness professionals with varying backgrounds. A triangulated appr…

Velocity-based resistance training: do women need greater velocity loss to maximize adaptations?

2021

Abstract Purpose Men and women typically display different neuromuscular characteristics, force–velocity relationships, and differing strength deficit (upper vs. lower body). Thus, it is not clear how previous recommendations for training with velocity-loss resistance training based on data in men will apply to women. This study examined the inter-sex differences in neuromuscular adaptations using 20% and 40% velocity-loss protocols in back squat and bench press exercises. Methods The present study employed an 8-week intervention (2 × week) comparing 20% vs. 40% velocity-loss resistance training in the back squat and bench press exercises in young men and women (~ 26 years). Maximum strengt…
