Non-selective closed kinetic chain exercises and or selective closed kinetic chain exercises has been shown to increase Vastus medialis obliquus muscle power in patellofemoral pain syndrome. However, the superiority of the exercises to each other has not been shown. This study aimed to evaluating the effects of different exercises on the stiffness of the Vastus medialis obliquus and vastus lateralis muscles, pain management, functional scores, and thigh circumferences.
Nowadays, many persons who exercise consume dietary supplements. Previous scientific studies have found that protein supplementation increases muscle mass when combined with an exercise program. In addition, vitamin D probably improves performance and muscle function. Likewise, ω3 fatty acids, apart from improving cardiovascular function, may also increase protein synthesis and performance. Thus, the aim of this study is to investigate the efficacy of a novel aquaculture-based sport supplement of proteins, ω3 fatty acids and vitamin D on physical performance, body composition, and the biochemical profile of persons following high-intensity functional training (HIFT). The efficacy of the experimental supplement (E) will be compared with whey protein (W) and maltodextrin (a carbohydrate) as placebo (P). Thirty healthy trained individuals (15 male and 15 female), aged 18-35, will take E, W, and P during three 6-week periods of HIFT (a different supplement each period) with three workouts a week and a washout (no supplement) period of 2 weeks between supplementation periods. E is a combination of powder, containing protein and vitamin D, and capsules containing ω3 fatty acids. When on E, participants will receive 0.6 g protein/kg body weight, 20 μg vitamin D, and 1.8 g ω3 fatty acids daily. When on W, they will receive 0.6 g protein/kg body weight and, when on P, they will receive 0.6 g maltodextrin/kg body weight daily. The order of E, W, and P will be random and counterbalanced. Throughout the study, participants will be on isoenergetic nutritional plans to avoid differences in energy intake that might compromise the validity of the study. The dietary plans will be individualized and will provided 1.0 g protein/kg body weight/day. Participants will undergo measurements of muscle strength, muscle endurance, aerobic capacity, and body composition prior to the first supplementation period, between periods, and after the third period. Also, blood amino acids, fatty acid acids, vitamin D, hematology, biochemistry, and hormones will be measured. To avoid bias, assessors will not know which supplement each participant is taking during each period. The main hypotheses of the study are: 1) Consumption of E will increase lean body mass compared to W and P; 2) consumption of E will improve muscle strength, muscle endurance, and aerobic capacity compared to W and P; and 3) consumption of E will result in a better blood amino acid, fatty acid, and vitamin D profile.
High-intensity functional training (HIFT), a new version of high-intensity interval training, has gained interest in recent years. HIFT is based on the CrossFit training template and includes multijoint movement patterns via both endurance and strengthening exercises. Research has shown positive effects of HIFT on body composition, cardiorespiratory fitness, and muscle performance of young individuals. The effectiveness of HIFT in higher ages and its protein requirements are less well documented. Protein requirements have been widely investigated in resistance training, where it has been found that protein supplementation may have additive beneficial effects on muscle strength and lean body mass. However, there is a research gap regarding the adaptations to HIFT when combined with protein supplementation. Thus, the aim of this research is to compare the effects of egg white supplementation, whey protein supplementation (as a positive comparator), and maltodextrin (a carbohydrate as placebo) on body composition, physical performance, and plasma amino acid profile in young and middle-aged trained individuals of both sexes who perform HIFT. Participants will take all three supplements for 6 weeks each, with 2 weeks of washout (no supplementation) in between, in random and counterbalanced order. Researchers will not know the supplementation status of the participants. Participants will receive 0.6 g of protein or placebo per kg body weight daily on top of isoenergetic dietary plans to avoid differences in energy intake that might compromise the validity of the study. The dietary plans will be individualized and will provided 1.0 g protein/kg body weight/day. The HIFT protocol will include multimodal patterns of movement, combining endurance and strengthening exercises with the use of equipment such as Total Resistance eXercise (TRX), Bosu, kettlebells, and barbells. Participants will undergo measurements of muscle strength, muscle endurance, aerobic capacity, and body composition at the beginning and end of the study, as well as during the two washout periods. Also, plasma amino acids, hematology, biochemistry, and hormones will be measured. Comparison of all these outcome measures between supplements will reveal whether protein supplementation is useful in HIFT.
The purpose of this study is to examine the effect of human skeletal muscle temperature during resistance exercise on myogenic and proteolytic signaling. Subjects will perform bilateral resistance exercise bouts at an intensity that should stimulate a muscle growth response in the Vastus Lateralis. During the resistance exercise, the subjects will receive a cold (10°C) intervention on the experimental limb, while receiving a neutral temperature intervention (22°C) on the control limb.
Current evidence suggests resistance exercise as the primary therapeutic strategy to prevent age-related functional decline. The National Strength and Conditioning Association recently stated that a properly designed resistance exercise program should include power exercises performed at higher velocities in concentric movements with moderate intensities. We should be aware that not all older adults are easily motivated to train in unfamiliar gym-based settings with high subscription fees. Therefore, implementation of traditional gym-based resistance exercise at a large scale has been found to be difficult. Interestingly, we have previously shown that the use of high external loads, which implies the need for specific facility memberships, is not necessary to induce neuromuscular gains. This provides strong support for home-based training intervention strategies. Stair climbing or stepping-based exercise constitute a promising avenue to ameliorate the cost-effectiveness and implementation potential of resistance exercise in older adults. Such exercises can induce muscular activation levels similar to high-load resistance exercise and result in similar or even better gains in muscle mass, strength and power compared to slow-speed resistance exercise when properly designed. However, the (neuro)-muscular effects of stair climbing exercise have never been compared to the more optimal power-oriented resistance exercise, which is the primary aim of this study. The secondary aim of this study is to examine if stair climbing exercise also has beneficial effects on cognition.
This study examined the effects of balance exercises performed with the Biodex Balance System (BBS) on nerve conduction, sensory symptoms, and muscle strength in patients with diabetes-related neuropathy.
The purpose of this study aimed to evaluate the effect of the three-month Chan-Chung qigong program in improving physical functional performance and quality of life in patients with mild to moderate cognitive impairments.A quasi-experimental design was adopted. Subjects were recruited from cognitive impairments outpatients these subjects,41were assigned to the control group and 41 to the experimental group in which Chan-Chuang qigong was administered.
Hypoxic exposure increases right ventricular (RV) afterload by triggering pulmonary hypertension, with consequent effects on the structure and function of the RV. Improved myocardial contractility is a critical circulatory adaptation to exercise training. However, the types of exercise that enhance right cardiac mechanics during hypoxic stress have not yet been identified. This study investigated how high-intensity interval training (HIIT) and moderate-intensity continuous training (MICT) influence right cardiac mechanics during hypoxic exercise (HE).
Exercise training is beneficial for both health and performance. Histamine has been shown to be involved in the acute exercise response. The current study addresses the role of histamine H1/H2 receptor signaling in the chronic training-induced adaptations. Results from this study will yield more insights into the molecular mechanisms of adaptations to exercise training.
