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.
This study was conducted to demonstrate the correlation between the functional movement screen and the isokinetic muscle strength with objective data. Investigators conclude that the use of FMS in combination with isokinetic systems will provide more detailed information on the prevention of injuries to sports and the improvement of performance.
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.
It is important to determine how high femoral anteversion, which is one of the lower extremity malalignments, affects physical performance and to what extent it affects the daily life of the individual. As far as we know, there is no study on this subject except for a study conducted by Staheli et al. in 1977. Therefore, the investigators planned to determine whether and to what extent high femoral anteversion has an effect on physical performance in healthy young adults.
The goal of this Clinical Trial is to analyze effect of Ophiochepalus striatus extract on serum IGF-1 and IL-6 levels in elderly patients with sarcopenia. The main questions it aims to answer are: 1. Can giving Ophiocephalus striatus extract at a dose of 2x5 grams for 2 weeks increase IGF-1 levels in elderly people with sarcopenia? 2. Can administration of 2x5 grams dose of Ophiocephalus striatus extract for 2 weeks reduce IL-6 levels in elderly with sarcopenia? 3. Can the administration of Ophiocephalus striatus extract at a dose of 2x5 grams for 2 weeks reduce the SARC-F score in elderly people with sarcopenia? 4. Can the administration of Ophiocephalus striatus extract at a dose of 2x5 grams for 2 weeks increase muscle mass in elderly people with sarcopenia? 5. Can the administration of Ophiocephalus striatus extract at a dose of 2x5 grams for 2 weeks increase muscle strength in elderly people with sarcopenia? 6. Can administration of Ophiocephalus striatus extract at a dose of 2x5 grams for 2 weeks improve physical performance in elderly with sarcopenia? Participants will: 1. Consume Ophiochepalus striatus extract 2x5 grams a day. 2. Checked blood before and after the intervention. 3. Measured muscle mass, muscle strength, and physical performance before and after the intervention.
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.
The goal of this randomized, double-blind, parallel group interventional study is to evaluate the effect of ketone bodies on healthy older adults (65-85 y) during 5 days of bed rest. The main questions it aims to answer are: Does supplementation of ketone bodies prevent the typical decline in muscle protein synthesis, muscle size, muscle function, insulin sensitivity, and muscle mitochondrial function that occurs in response to bed rest? Researchers will compare ketone supplements (KET) to an energy matched control beverage (carbohydrates and fats) to see if the ketones can rescue the decline in muscle protein synthesis rates, muscle loss, muscle function, insulin sensitivity, and mitochondrial function due to 5 days of bed rest. This may positively impact the heath of older adults subjected to bed rest.
INTRODUCTION: There are several ways to assess muscle strength: not only subjective ways, but also high standard equipment, such as isokinetic dynamometers. These, however, are expensive, and require extensive training. Over the years, manual dynamometers were produced, portable equipment that simplify its use. Among them, a national equipment was developed, but its reliability and validation are yet to be confirmed, compared to equipment already used, such as the Lafayette®. OBJECTIVE: Assess the reliability of a new manual dynamometer - Medeor® device (SP Tech model) -, in relation to the gold standard, Lafayette® device (model 01165), already validated, in the evaluation of muscle strength of the knee and hip groups. METHODS: A total of 26 recruits of both sexes were selected. Muscle strength was measured by Lafayette® and Medeor® dynamometers in the following groups: knee flexors and extensors; flexors, extensors, abductors, adductors, hips internal and external rotators. Each data was collected 3 times, and then the average was calculated.
It has been suggested that applying acute vibration exercises enhances muscle force, like several weeks of resistance training. The present study investigated the effects of local vibration with two different frequencies on biceps brachii isometric muscle strength and grip strength in healthy young men. Isometric strength of the biceps brachii muscle and grip strength were assessed at baseline and after vibration training (immediate, 10 minutes, and 20 minutes post vibration training).
