Filter by:Crossfit® is a training modality that consists in functional movements, constantly varied and executed at high intensity. Both training sessions and competitions involve physically demanding activities, which in addition to being performed at very high intensity also involves the aerobic metabolism pathway. These characteristics led to very high metabolic and muscular stress, as well as decrease in physical performance immediately after competitions and training sessions. The cumulative effects of the metabolic and muscular stress can be a precursor of injuries. Studies using different therapeutic modalities aiming to improve post-exercise recovery are needed in order to tackle this issue. However, to the date there are no studies investigating the effects of different therapeutic modalities in an exercise modality such as Crossfit®. Therefore, the aim of this project is to assess the effects of different therapeutic modalities on performance and muscle recovery of Crossfit® athletes.
Local muscle endurance (LME) is the ability of a muscle(s) to resist fatigue and is needed for daily activities of life such as climbing stairs, lifting/moving objects, and in sport contexts like rock climbing, mixed martial arts, cross-fit, kayaking and canoeing. Therefore, the investigators want learn how to improve LME and understand what in human bodies changes during exercise training to cause these changes. The investigators know that lifting weights improves muscle strength which is believed to improve LME. Specifically lifting less heavy weights (LLRET) for more repetitions leads to greater gains in LME opposed to heavier weights for fewer repetitions. Therefore, lifting less heavy weights likely causes greater changes in our muscles than lifting heavier weights that cause improvements in LME. Aerobic exercise preformed at high intensities in an interval format (HIIT) may also help improve LME by increasing our muscle's ability to produce energy during exercise. Therefore, the investigators want to see which of LLRET or HIIT leads to greater improvements in LME.
The primary objective of this proposal is to determine the effects of post-exercise peanut consumption on long-term aerobic and resistance exercise training adaptations in middle-aged men and women. We will determine the impact of peanuts on exercise training-induced improvements in muscle strength, gains in muscle mass, and improvements in cardiorespiratory fitness and metabolic capacity.
This is a randomized controlled trial aimed to investigate the effects of different supplementary protein sources on muscle adaptations to resistance exercise. Young, healthy, recreationally active participants consuming an omnivorous diet with protein intake within recommended dietary allowance (RDA) (i.e.; 0.8-1.0 g.kg-1. d-1) will be recruited to undergo a 12-wk supervised resistance training program in combination with the intake of three 15-g daily doses (45g. d-1 total) of either a mixed plant- (i.e.; soy and pea protein) or animal-based (i.e.; whey protein) protein in drink form as a supplementary source of protein to their main meals of the day (i.e.; breakfast, lunch, and dinner). Before (PRE) and after (POST) the 12-wk intervention, participants will be assessed for body composition by dual-energy X-ray absorptiometry (DXA), muscle cross-sectional area (ultrasound) and fiber cross-sectional area (muscle biopsy), and maximal isotonic strength (1RM). Training consists of a resistance training (RT) program individually supervised by a researcher blinded to treatment in a laboratorial setting. Assessments will also be conducted in a blinded fashion.
Muscle loss (ultrasound quadricep muscle) and muscle strength (handgrip and knee extension strength) will be compared between COVID-19 and non COVID-19 critically ill patients.
To compare the difference of effectiveness for stable COPD patients with poor nutritional status among three groups named health education, upper and lower limb exercises, and oral nutritional supplements. Then formulate the best pulmonary rehabilitation guidance strategy according to the result of this trial.
The aim is to study the impact of muscle strength measured in ICU and after ICU discharge on health-related quality of life measured after hospital discharge.
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.
In last years it has been demonstrated that photobiomodulation therapy (PBMT) has ergogenic effects, improving muscular performance and accelerating post-exercise recovery. However, many aspects related to these effects and its' clinical applicability remain unknown. Therefore, the aim of this project is to evaluate the ergogenic effects of PBMT in detraining after a strength training protocol.
