Filter by:Closed kinetic chain (CKC) exercises are exercises in which body weight is carried on the distal segment. It is considered advantageous and reliable in many respects compared to open kinetic chain exercises (OKC). For the restoration of functional stability in shoulder rehabilitation, it is recommended to use CKC exercises that carry body weight from the early period. Plank exercise, which is frequently used to strengthen the core area in rehabilitation programs, is performed by transferring weight on the upper extremity. For this reason, it is thought that this exercise will provide an isometric load on the shoulder and scapula muscles. In many previous studies, it has been observed that scapular muscle activations also change with the changes in stability (support surface properties, etc.) in plank exercises and variations in a way that provides a more stable exercise environment. However, as the difficulty level of the used moving floor increased (using softer or unstable surfaces), it was seen that the increase in muscle activation levels was more in favor of the upper trapezius muscle (UT). In a study, it was observed that the UT / Middle Trapeze (MT), UT / Lower Trapezius (LT), UT / Serratus Anterior (SA) ratios were lower in the 3-point supported plank exercise performed on one hand. For this reason, it is thought that while the difficulty level of plank variations is increased in shoulder rehabilitation, body position changes will be more effective in maintaining optimal scapular muscle activation rates instead of using a moving floor. Based on this information, investigating the muscular activation levels for the scapular and shoulder girdle muscles during different variations of the plank exercise in terms of load levels in the targeted muscles will provide valuable information for the management of shoulder exercise programs and post-operative rehabilitation. It was planned to include 21 healthy physically active individuals between the ages of 18-45 in the study. Muscle activation levels during maximum voluntary isometric contraction (MVIC) of each muscle will be recorded to normalize muscle activation levels during plank variations. Muscle activation levels will be evaluated with a surface electromyography device (Noraxon, Myomotion, USA).
This study is a randomized controlled trial that will look at whether virtual, team-based exercise improves burnout, sense of community, and mentorship connections among medical students, residents, fellows, and physicians.
The present project aims to investigate the interaction between training-induced blood volume expansion (plasma- and red blood cell volume responses), central as well as peripheral cardio-vascular adaptations. We will investigate cardiovascular responses through one year of training in recreationally active men and women as well as endurance athletes undertaking shorter training-periods/interventions with environmental heat-stress. The overall purpose with the project is to investigate the physiological effects of prolonged aerobic exercise on central cardiovascular parameters and peripheral effects in the muscle tissue in untrained individuals. Further, we want to compare these effects to exposure to environmental stress (heat) on performance well trained individuals. The present study consist of three parts using the same methodology in different populations to elucidate the above mentioned mechanisms. The first part is a larger training intervention in untrained/recreationally active men and women aiming at evaluating the initial cardiovascular adaptations to an exercise training regimen. In addition there are two parts aimed to elucidate the mechanisms leading to further improvements in cardiovascular and blood volume adaptations from exercise training in a different environmental condition and artificially elevated PV in already highly adapted endurance athletes.
Bone morphogenetic protein (BMP) 9 from the BMP family has an important role in the remodeling of bone and cartilage. Due to these features, BMP9 can play an important role in especially anaerobic exercise training adaptations. However, the role of anaerobic exercise in these effects is still unclear. The aim of this study is to investigate the role of BMP9 on the effects of acute and chronic anaerobic exercise on bone metabolism markers. Postprandial venous blood samples were taken pre- and post- acute YOYO intermittent recovery test (level 1) in 40 trained male athletes aged 18-35 who did anaerobic sports (such as basketball, volleyball and handball) and 41 sedentary volunteers aged 18-35. Serum BMP9, as markers of bone formation and resorption; alkaline phosphatase (ALP), C-terminal telopeptide of type 1 collagen (CTX1), cartilage oligomeric matrix protein (COMP) and calcium levels were determined. The data to be obtained as a result of our study can give information about the relationship between the skeletal and bone health of the athletes and anaerobic exercise.
To describe the primary and secondary outcomes of athletes during a Cardiopulmonary Exercise Test (CPET) on a cycle ergometer with and without a face mask.
A double-blind randomized controlled trial design is used in this study. A mixed design of 2 (pollution reduction group vs. no pollution reduction group) × 3 (high intensity intermittent exercise [HIIT], moderate intensity of aerobic exercise [MICT] and control group [CONT]) is used. 93 subjects recruited by advertising will be randomly divided into 6 groups: high intensity exercise group (pollution reduction vs no pollution reduction), moderate intensity aerobic exercise group (pollution reduction vs no pollution reduction) and Stretching group (Control) (pollution reduction vs no pollution reduction).
This pilot study is a small sample (N=46) 16-week clinical trial with a follow-up after 24-weeks among sedentary adults >60 y with a BMI >25 kg/m2 to tests the impact of a hybrid artificial intelligence behavior change system (Companion) on physical activity. Participants will be randomized to a control and intervention group. All participants will engage in a proven supervised exercise program from week 1 to 16. Only the intervention group will receive Companion from week 1 to 16.
This study will examine whether providing physical activity counseling and guidance to patients post bariatric surgery, along with long-term personal follow-up for six months after the surgery, may increase the level of physical activity, and it's effect on anthropometric and functional measures.
A four-arm randomised pilot trial involving: 1. Physical activity programme only - live exercise sessions, social support, standardised text messages 2. Individual behaviour change support only - regular one-to-one video calls with an activity mentor 3. Combined - Physical activity provision and individual behaviour change support 4. Usual care control All groups will be provided with a menu of physical activities. Objectives. To conduct a RE-AIM evaluation of a 6-month multi-component PA intervention for adolescent girls, through investigating: - Who the intervention reaches, how representative they are for the population (Reach, Adoption) and who is most likely to benefit from the intervention (Reach); - The extent to which the intervention is delivered as intended (Implementation), and factors that affect this (Adoption); - Preliminary impact on participants' PA, sedentary behaviour, cardiovascular fitness and psychological wellbeing at 3, 6 and 12 months (Effectiveness, Maintenance); - The qualitatively examine the acceptability of the intervention for adolescent girls, and identify necessary refinements; - To gather data to inform a sample size calculation for a main trail
It is becoming increasingly evident that sleep plays an essential role for human health, and it represents an important biophysiological variable for athletes' well-being and recovery. The International Olympic Committee recently highlighted the importance of obtaining sufficient sleep volume and quality among athletes, but acute sleep deprivation is not unusual. Several factors, both endogenous and exogenous, are able to negatively influence sleep in athletes: body temperature, altitude, chronotype, training volume, anxiety, westward and eastward travels, and many others. Since December 2019, when a new coronavirus (SARS-CoV-2) was originally revealed by an ophthalmologist in Wuhan (Hubei province, China), a related severe acute respiratory syndrome - namely COVID-19 - has been spreading at a pandemic rate, putting global health systems under unprecedent pressure. Italy, as the first Western country tremendously hit by this disease outbreak, has become the iconic resilient outpost under international policymakers' attention. When initial clusters were identified, restrictive actions to curb isolated upsurges of infection were taken by the health region system of Lombardy, thereafter, were extended to all northern Italy and to the entire country. From February 21, when the first Italian COVID-19 case was diagnosed in southern Lombardy, to March 22, when Italian's government restrictions to contain the pandemic were extended, prohibiting all non-essential business activities and banning all movements of people nationwide, the country faced an unchartered scenario, from several standpoints, along with the psychosocial one. Inevitably, the Covid-19 outbreak has largely influenced the daily life of athletes too. Therefore, the primary aim of this study was to examine the differences in athletes' sleep quality, quantity and training volumes during the social confinement due to the virus outbreak. For this purpose, a survey will be used. This variables will be evaluated in 3 different time frames: 1) May 2020; 2) September 2020; 3) January 2021.
