One of the most widespread illnesses, hypertension can cause other cardiovascular conditions that shorten life expectancy and lower quality of life. Primary hypertension is the most typical type, and ...while there are some risk factors, we cannot determine what is the primary cause. We should first change our lifestyles before using medications. Sport activity is the strategy that has the most potential. Numerous researchers have attempted to evaluate its impact on hypertension control. They all concurred that engaging in almost any sport can aid in the management of hypertension. Other studies looked at the best sports to keep hypertension under control. They experimented with isometric exercises, tai chi, brisk walking, and aerobic exercise. Matching the appropriate sport to the level of hypertension can be important too.Athletes experience hypertension as well, despite the fact that exercise is beneficial for the condition. Because of anti-doping regulations, there are some restrictions on how they can be treated.In addition to exercise, other lifestyle changes are crucial in the treatment of hypertension. It involves changing one's diet, attempting to lose weight, and avoiding stressful situations.
Hair loss is a problem that affects many people around the world. Androgenic alopecia (AGA) is the most common cause of hair loss affecting up to 50% of men and 40% of women over the age of 50. This ...type of hair loss is mediated by androgens, the strongest of which is dihydrotestosterone (DHT). This hormone influences the weakening hair follicles. The problem of excess DHT and the associated androgenic hair loss may concern people practicing sports, especially aerobic disciplines of moderate and high intensity. In the recent decades, many topical and oral therapies have been introduced to delay and stop hair loss. However, commonly used medications have only a partial and temporary effect, therefore alternative treatment methods are needed. Platelet-rich plasma (PRP) is known, among other things, for its use in orthopedics. The use of PRP may benefit athletes in the treatment of injuries to tendons, ligaments, muscles and cartilage. Many publications indicate good results with the use of PRP in the treatment of hair loss.
The aim of this study is to summarise the published reports on the effect of platelet-rich plasma (PRP) on hair loss prevention in people with androgenic alopecia (AGA) and to analyse the papers discussing androgen levels in physically active people.
The paper aims at making us understand what kind of relation exists between certain aspects concerning the extrapolation of the data obtained by the sportswomen and which of this data must be ...analyzed and included in the model, when a certain issue is studied.
The thesis of agonality as the fundamental characteristic of the Classical Greek culture is supported in the article. Competitiveness as the system-forming principle of the Greek society penetrates ...all spheres of the social life. Acquisition of high status by agonality is connected with the Greek cognitive peculiarities.
Hip Osteoarthitis (OA) risk is sport-specific and depends on frequency, intensity, and type of mechanic stress the hip is subjected to. This retrospective observational study aims to investigate the ...safety and performance of Hymovis (HYADD-4) injection, a hexadecyl (C-16) HA-derivative, when used to manage symptomatic hip OA in active middle-aged sportsmen over a 24-month observation period.
The retrospective analysis included clinical records of active sportsmen, aged between 40 and 65 years, and suffering from symptomatic Kellgren-Lawrence grade II to III hip OA, treated with two (24 mg/3 ml) Hymovis injections, two weeks apart, every 3–4 months, for two years. When available, data on MRI examination were included in the analysis as well as Heidelberg Sports Activity Score (HAS) and Copenhagen Hip and Groin Outcome Score (HAGOS) questionnaires.
Thirty patients (56.4 ± 7.3 years) were included in the study, sixteen cyclists and 14 tennis players. For all patients, HAS and most HAGOS scores improved significantly (p < 0.05) at the first control visit (4 months) and further improved over time. For all other scores an important clinical benefit was experienced by more than 50% of participants. No adverse events were recorded.
Treatment of hip OA in active sportsmen with Hymovis seems a safe and effective approach for the management of OA symptoms, by potentially protecting cartilage and subchondral bone from further damage.
ABSTRACTThe histologic features of aging muscle suggest that denervation contributes to atrophy, that immobility accelerates the process, and that routine exercise may protect against loss of motor ...units and muscle tissue. Here, we compared muscle biopsies from sedentary and physically active seniors and found that seniors with a long history of high-level recreational activity up to the time of muscle biopsy had 1) lower loss of muscle strength versus young men (32% loss in physically active vs 51% loss in sedentary seniors); 2) fewer small angulated (denervated) myofibers; 3) a higher percentage of fiber-type groups (reinnervated muscle fibers) that were almost exclusive of the slow type; and 4) sparse normal-size muscle fibers coexpressing fast and slow myosin heavy chains, which is not compatible with exercise-driven muscle-type transformation. The biopsies from the old physically active seniors varied from sparse fiber-type groupings to almost fully transformed muscle, suggesting that coexpressing fibers appear to fill gaps. Altogether, the data show that long-term physical activity promotes reinnervation of muscle fibers and suggest that decades of high-level exercise allow the body to adapt to age-related denervation by saving otherwise lost muscle fibers through selective recruitment to slow motor units. These effects on size and structure of myofibers may delay functional decline in late aging.Trial registrationClinicalTrials.gov (NCT01679977).
This paper presents a wearable inertial sensor network and its associated activity recognition algorithm for accurately recognizing human daily and sport activities. The proposed wearable inertial ...sensor network is composed of two wearable inertial sensing devices, which comprise a microcontroller, a triaxial accelerometer, a triaxial gyroscope, an RF wireless transmission module, and a power supply circuit. The activity recognition algorithm, consisting of procedures of motion signal acquisition, signal preprocessing, dynamic human motion detection, signal normalization, feature extraction, feature normalization, feature reduction, and activity recognition, has been developed to recognize human daily and sport activities by using accelerations and angular velocities. In order to reduce the computational complexity and improve the recognition rate simultaneously, we have utilized the nonparametric weighted feature extraction algorithm with the principal component analysis method for reducing the feature dimensions of inertial signals. All 23 participants wore the wearable sensor network on their wrist and ankle to execute 10 common domestic activities in human daily lives and 11 sport activities in a laboratory environment, and their activity recordings were collected to validate the effectiveness of the proposed wearable inertial sensor network and activity recognition algorithm. Experimental results showed that our approach could achieve recognition rates for the 10 common domestic activities of 98.23% and 11 sport activities of 99.55% by the 10-fold cross-validation strategy, which have successfully validated the effectiveness of the proposed wearable inertial sensor network and its activity recognition algorithm.
Purpose
Vertebral body tethering (VBT) is an alternative to fusion for selected scoliosis patients. As VBT does not limit spine mobility, it has been propagated that this technique allows a quicker ...return to physical activity than fusion. However, no data are available to support this statement. Aim of this study was to quantify how much time patients required to resume preoperative activity level and to seek possible associations between return to physical activity and demographic, radiographic and surgical data.
Methods
One year postoperatively, the validated sport activity questionnaire (SAQ) was administered to all skeletally immature patients who underwent VBT at our institution. SAQ data were analyzed and a multivariate analysis was conducted to investigate associations between SAQ and demographic, radiographic and surgical data.
Results
Thirty-one patients aged 14.5 years completed the SAQ. Within 3 months from VBT, 97% returned to school, 61% resumed physical education, 97% carried a backpack, 68% run, and 82% rode a bike; 70% bent within a month from VBT. Ninety-four percent of patients returned to their preoperative athletic level. Within 3 months, 63% of responders resumed noncontact, 61% contact and 53% collision sports. No relevant associations were observed between the SAQ and demographic, radiographic and surgical data. In particular, number of instrumented vertebrae, level of the lowest instrumented vertebra and postoperative Cobb angle did not influence patients’ return to preoperative activities.
Conclusion
VBT allows patients to quickly return to their preoperative activity level, irrespectively of the postoperative Cobb angle or type of instrumentation.
Automatically clustering various sophisticated human activities (e.g., dancing, martial arts, and gymnastics) based on their quality scores is an indispensable technique in physical training, ...human–computer interaction, etc. Conventionally, many action recognition models are built upon the visual/semantic appearance of human body movements. Recently, due to the introduction of Microsoft Kinect, many skeleton-based human action understanding frameworks have been proposed. In this work, we propose a novel method to cluster the quality of complicated human actions towards contactless operative video reading system (COVRS). More specifically, we first extract the skeleton by leveraging the Kinect, which is subsequently fed into an aggregation deep neural network to extract the deep feature for each human action skeleton. In COVRS, the human hand gesture is an informative clue. Thus, we propose a ranking algorithm to extract the position of human five figures, based on which the deep hand gesture representation is hierarchically learned. Noticeably, it is observable that, the acoustic feature from many human activities also contributes to the quality assessment. We extract multiple acoustic features from the audio associated with each human activity video. Finally, based on the above human skeleton and hand gesture deep features, as well as the shallow acoustic features, we employ a probabilistic model to integrate them for clustering the various human activities using the quality of COVRS. Comprehensive experimental have demonstrated the effectiveness and efficiency of our method. Besides, empirical results have shown that our probabilistic quality model is highly extensible, where additionally visual/acoustic features can be encoded according to different applications.
