Filter by:The objective of this study is to assess the impact of different positions of the glenohumeral joint on the maximum muscle contraction of different shoulder muscles. The muscles do not contract with the same intensity depending on the position of the arm in relation to the trunk. With the determination of this optimal position to activate the shoulder muscles as much as possible, we will be able to strengthen the patients during their revalidation.
There are indications that phosphatidic acid (PA) supplementation is capable of enhancing gains in strength and muscle mass in response to strength training, although the literature is still incipient and controversial. Given the possible benefits in terms of maintenance and increased skeletal muscle mass, which still need confirmation, this study aims to examine the effectiveness of PA supplementation in two different doses in increasing skeletal muscle mass and strength in adult men undergoing to 8 weeks of strength training. For this, about 45 men will be randomly allocated to one of three treatments at a ratio of 1:1:1: PA 750mg per day, PA 375mg per day, or placebo (cornstarch, 750mg per day). All participants will undergo a 8-week strength training program, 3 times a week, totaling 24 sessions, which will begin with the start of supplementation. Individuals will be assessed for maximum dynamic strength of upper and lower limbs, resistance to dynamic strength of upper and lower limbs, body composition, muscle cross-sectional area and food consumption. Samples of venous blood will also be collected to determine the concentration of creatine kinase (CK), lactate dehydrogenase (LDH), testosterone, insulin-like growth factor type 1 (IGF-1), growth hormone (GH) and cortisol. These evaluations will be carried out before (PRE) and after (POST) the period of supplementation and training. Additional blood samples will be taken 48 hours after the first and last training sessions, for specific determination of blood muscle damage markers: CK and LDH.
Golf is becoming increasingly popular in Germany. However, the biomechanical and motor challenge of golf should not be underestimated. Nevertheless, only very few amateur golfers carry out serious preparation and conditioning as part of a strength/stabilization program. The main argument for this limitation is the aspect of "limited time resources". A solution to this problem could therefore be the time-effective and highly individualizable whole-body electromyostimulation (WB-EMS) technology. The aim of the present study is to evaluate the effectiveness of 16 weeks of WB-EMSapplication on maximum strength of the lower extremities, trunk stability and (golf) handicap in male amateur golfers in a (randomized) controlled setting.
The aim of the present research is to define the effects of short manual treatment of soft tissues compared to mechanisms explaining in Delayed Onset Muscle Soreness (DOMS) among sport climbers and to address the mechanisms of peripheral and central sensitization involved in DOMS phenomena.
This study consists of a free-living, 6-week fish oil (FO) or placebo (PLA) supplementation intervention alongside participants' habitual resistance exercise training (RET) regimens. Twenty young, healthy resistance-trained subjects who do not currently supplement with FO will be recruited to participate. An eligible participant will be between ages 18 and 35 and will have a minimum of two years of RET experience. Participants will be randomized into a FO group and a PLA group. The FO group will supplement with 4g/day of FO (4g fish oil concentrate: 2g EPA+ 1g DHA) and the PLA group will consume 4g/day of coconut oil (saturated fatty acids), as administered via gel capsules, in conjunction with their current RET program. Prior to intervention all participants will complete baseline biometric, strength, and neuromuscular testing. Participants will also have blood drawn to test for omega-3 fatty acid status, and complete and return a 3-day diet record and a physical activity recall. In order to monitor adherence to supplementation, FO and PLA bottles will also be returned weekly and pills will be counted. 3-day diet records will be obtained to ensure calorie and protein intakes remain consistent throughout the intervention period. Weekly physical activity records will also help to ensure consistency of participant training and to make sure all participants are following their training regimes in a progressive fashion. Following 6 weeks of FO or PLA supplementation, subjects will repeat all initial biometric, strength and neuromuscular testing, as well as a second, post-intervention blood draw.
The present project aims to investigate the acute and chronic effects of laser photobiomodulation (PBM) at 808 nm on muscle performance in physically active elderly women. The hypothesis of this study is that laser PBM would improve muscle strength (i.e., MVIC and 1RM) and endurance (i.e., repetitions-to-failure, blood lactate levels), functional capacity (i.e., short physical performance battery score), and rating of perceived exertion when compared with placebo laser.
The study was conducted to investigate the effect of preoperative graduated abdominal strengthening exercises and Russian stimulation on the abdominal muscles strength after ventral hernioplasty by using isokinetic dynamometer and Ultrasonography as methods of measurement.
The present project aims to investigate the effects of high-quality protein (whey protein) vs. low-quality protein (collagen) on muscle mass and function (e.g., strength and power) during a 10-wk resistance training program in young adults. It will be tested the hypothesis that leucine-matched collagen should promote similar gains on muscle function and mass compared to whey protein supplementation.
This study will examine the effects of Oceanix™, an antioxidant supplement, on muscle performance, immune and endocrine function, recovery and safety in participants undergoing resistance training. Measures of muscle performance will include isometric testing in the bench-press and mid-thigh pull and ground reaction forces in the counter movement- and squat-jump. Markers of immune function will include salivary immunoglobulin A (IgA) as well as serum total antioxidant capacity (TAC) and superoxide dismutase (SOD) while endocrine function will be measured by salivary cortisol and testosterone. Recovery will be measure by plasma creatine kinase (CK) and perceptual measures will be assessed using a validated perceived recovery status (PRS) scale. Safety metrics will be indicated by a comprehensive metabolic panel (CMP), complete blood count (CBC), and urinalysis (UA). Additionally, the modified Borg Rating of Perceived Exertion (RPE) will be administered following each training session to grade physical exertion and monitor progression of the training protocol.
The aim of this study was to evaluate the changes in the thickness of abdominal muscles during activation of thoracolumbar fascia through contracting the gluteus maximus and latissimus dorsi muscles. The hypothesis was that the thickness of transversus abdominis and internal oblique would show greater increase when abdominal contraction was performed with simultaneous contraction of gluteus maximus and latissimus dorsi (bridge with arm extension) than that of abdominal contraction alone (abdominal hollowing) or abdominal contraction with simultaneous activation of only gluteus maximus (bridge). Thirty healthy subjects (15 women, 15 men) were enrolled in this cross-sectional study. Thickness of transversus abdominis, internal oblique and external oblique muscles were evaluated using ultrasound at rest and during three exercise positions: abdominal hollowing in neutral spine, bridge, and bridge with isometric arm extension using ultrasound device equipped with 55 mm convex array transducer
