Effects of Functional Strength Training on Functional Movement and Balance in Middle-Aged Adults
2021
Functional movement deficiencies cause falls and injuries in adults. Functional strength training (FST) is emerging as a new training method for athletes, middle-aged and older adults, to improve functional movement: The present study was conducted in order to investigate the effects of FST on balance and functional movement in healthy and independent middle-aged adults. The sample for this study consisted of 46 physically active individuals (24 female and 22 male). A total of 46 subjects were divided based on randomly into the functional strength training (FST) group (n = 26) aged: 51.55 ± 3.73 years; height: 168.69 ± 8.8 cm; body mass: 75.88 ± 12.18; and traditional s…
Effect of low-load hamstring strength training on the H/Q ratio and electromyographic activity in various gymnastic actions in young aesthetic group …
2013
Muscle balance is an important factor for decreasing injury risks among sports, as weak ago-nist-antagonist strength ratio may predispose to injuries. Hamstring-to-quadriceps (H/Q) strength ratio has been studied in several sports in order to describe the muscular balance of thighs. During pubertal longitudinal growth, hamstrings may be weaker due to the mechanical stress of growth. As both hamstring flexibility and knee extension strength are important for aesthetic group gymnastics (AGG), the H/Q strength ratio might be expected to be low among this sport. Describing muscle activation patterns of hamstrings and quadriceps femoris in AGG actions is efficient for determining the H and Q act…
Neural Adaptations to Strength Training
2018
Scientific study of strength training has revealed numerous physiological mechanisms that contribute to: (1) acute fatigue from a single strength training session and (2) chronic adaptation to repetitive and systematic strength training. Therefore, the purpose of this chapter is initially to discuss potential neural mechanisms that influence force production from the perspective of a single repetition. Thereafter, the chapter will highlight scientific evidence for candidate neural mechanisms that acutely limit force production during a single strength training session and long-term adaptations caused by strength training. For some of these potential neural mechanisms, there is strong scient…
Individuality of responses to bilateral and unilateral volume equated hypertrophic strength training in physically active men
2019
Purpose. The purpose of the present study was to investigate possible differences between unilateral and bilateral strength training during ten weeks progressive hypertrophic strength training and six weeks detraining period. Furthermore, it was examined possible different individual responders in muscle hypertrophy during strength training and, how those different responders would behave during the detraining phase following the training period. Methods. The present intervention included ten weeks of progressive hypertrophic resistance training followed by six weeks of detraining in healthy young men (n=24). Ultrasound was used to measure vastus lateralis (VL) muscle cross-sectional area (…
Isometric force-time parameters in monitoring of strength training : with special reference to acute responses to different loading resistances
2017
The aim of the present series of studies was to investigate acute neuromuscular responses to (1) different strength training loadings and using (2) different external resistances. In addition, chronic adaptations and dynamic performances were compared to (3) the changes in isometric force-time parameters at the group level, and to (4) the individual timing of the improvement in the rate of force development (RFD) due to hypertrophic or maximum strength followed by power strength training periods. The latter one was achieved by systematic, repeated monitoring. Sixty-nine physically active men (20-35 yrs), but not experienced in resistance training, took part in the present series of studies.…
Postoperative education concerning the use of the upper limb, and exercise and treatment of the upper limb: cross-sectional survey of 105 breast canc…
2003
In this retrospective survey we investigated the recall of breast cancer patients (n=105) 6 months after the operation concerning postoperative instructions on exercises for shoulder mobility, and instructions for oedema prevention and treatment, upper limb strength training and the use of the upper limb in daily activities. Patients also described the content in their own words and ranked the instructors who had mostly given this education. Operation type and length of hospital stay did not have any effect on the education recalled, but the age of the respondent had some effect (r=−0.23, p<0.05). The Wilcoxon signed ranks test showed that the most commonly reported item was instructions on…
Muscle hypertrophy, strength development, and serum hormones during strength training in elderly women with fibromyalgia.
2005
To examine the effects of strength training on maximal force, cross-sectional area (CSA), and electromyographic (EMG) activity of muscles and serum hormone concentrations in elderly females with fibromyalgia (FM).Twenty-six patients with FM were randomly assigned to a training (FMT; n = 13; mean age 60 years) or a control (FMC; n = 13; 59 years) group. FMT performed progressive strength training twice a week for 21 weeks. The measurements included maximal isometric and concentric leg extension forces, EMG activity of the vastus lateralis and medialis, CSA of the quadriceps femoris, and serum concentrations of testosterone (T), free testosterone (FT), growth hormone (GH), insulin-like growth…
A comparison of elastic tubing and isotonic resistance exercises.
2010
The aim of this study was to assess eff ects of a short-term resistance program on strength in fi t young women using weight machines / free weights or elastic tubing. 42 physically fi t women (21.79 ± 0.7 years) were randomly assigned to the following groups: (i) the Thera-Band ® Exercise Station Group (TBG); (ii) the weight machines / free weights group (MFWG); or (iii) the control group (CG). Each experimental group performed the same periodised training program that lasted for 8 weeks, with 2 – 4 sessions per week and 3 – 4 sets of 8 – 15 submaximal reps. A load cell (Isocontrol; ATEmicro, Madrid, Spain) was used to test the evolution of the Maximum Isometric Voluntary Contraction (MIVC…
Effects of a short-term resistance program using elastic bands versus weight machines for sedentary middle-aged women.
2008
This study was designed to determine whether different effects on functional capacity and body composition were produced by using different devices (elastic bands (EBs) versus weight machines (WMs)) with the same resistance training program. Forty-five healthy sedentary middle-aged women volunteers were chosen and randomly assigned to 1 of 3 groups: 21 subjects trained using EBs (EBG), 14 in trained using WMs (WMG), and 10 were controls (CG). Both exercise groups trained with a periodized muscular endurance program twice a week for 10 weeks, with a total of 6 exercises per session for the major muscle groups. Exercise intensity was equalized by jointly monitoring the same targeted number of…
Can supplementation with vitamin C and E alter physiological adaptations to strength training?
2014
Published version of an article from the journal: BMC Sports Science, Medicine and Rehabilitation. Also available from the publisher: http://dx.doi.org/10.1186/2052-1847-6-28 Background: Antioxidant supplementation has recently been demonstrated to be a double-edged sword, because small to moderate doses of exogenous antioxidants are essential or beneficial, while high doses may have adverse effects. The adverse effects can be manifested in attenuated effects of exercise and training, as the antioxidants may shut down some redox-sensitive signaling in the exercised muscle fibers. However, conditions such as age may potentially modulate the need for antioxidant intake. Therefore, this paper …
