"Training recovery"

This study investigated the effect of prolonged exertion on cardiac parasympathetic (cPS) reorganization and associated aerobic performance in response to repeated short-lasting submaximal exercise bouts (SSE) performed for 7 days following prolonged exertion. In 19 recreational runners, heart rate (HR) and HR variability (HRV) indices (lnRMSSD, lnHF, and lnLF/HF) were monitored pre- and post-submaximal graded cycling performed on consecutive days following a half-marathon (HM) and compared with the baseline, pre-HM values...

Capillary dried blood spot (DBS) samples facilitate field-based collection without venipuncture. This pilot study aims to evaluate the viability of creatine (Cr) and creatinine (Crt) quantification using fresh capillary serum (CrS /CrtS ) and DBS samples (CrDBS /CrtDBS ), using Flow Injection Analysis Mass Spectrometry (FIA - MS). Nine Olympic Athletes provided a capillary blood sample to assess CrS /CrtS and CrDBS /CrtDBS quantified by FIA - MS. No difference between CrtS (mean ± SD: 813.6 ± 102.4 μmol/L) and CrtDBS (812...

Heart rate variability (HRV) has been utilized in both medicine and sports sciences as an important marker for managing stress, indicating diseased states, and monitoring training/recovery. HRV reflects the autonomic balance of the sympathetic (SNS) and parasympathetic (PNS) nervous systems. High PNS activity is correlated to high HRV. The frequency and time domains of an ECG may be analyzed to determine the influence of PNS activity. HRV has been shown to be influenced by exercise training; however, meditation and guiding breathing techniques may also influence HRV...

BACKGROUND: Previous studies have shown that compression garments may aid recovery in acute settings; however, less is known about the long-term use of compression garments (CG) for recovery. This study aimed to assess the influence of wearing CG on changes in physical performance, subjective soreness, and sleep quality over 6 weeks of military training. METHODS: Fifty-five officer-trainees aged 24 ± 6 y from the New Zealand Defence Force participated in the current study...

The use of oral appliances is considered effective in improving sport performance. Jaw clenching or stretching, improved breathing or positioning of the jaw have been proposed to explain the improvement. In this study, we reported the effects of regularly practiced mandibular stretching at submaximal opening of the jaw in Crossfit athletes. Seventeen test subjects undergoing mandibular stretching (MS) showed significantly reduced (p0.001) performance time in a high-intensity workout measured before and after seven days of 10-minutes stretching practiced twice daily, while no improvement was observed in control subjects who did not perform the stretching...

Background : The purpose of this study was to examine the relationship between training load and next-day recovery in collegiate American football (AF) players during pre-season. Methods : Seventeen athletes (Linemen, n = 6; Non-linemen, n = 11) participated in the 14-day study wearing monitoring (accelerometer + heart rate) sensors during on-field practice sessions throughout pre-season to assess the physiological (PL), mechanical load (ML) and recording of session RPE (sRPE load) immediately post-practice...

BACKGROUND: Current consensus and position statements recommend that concussed patients be asymptomatic upon the initiation of the graduated return to activity (RTA) protocol. However, a significant number of concussed patients are beginning their RTA protocols while endorsing symptoms. PURPOSE: To characterize symptom endorsement at the beginning of the RTA protocol and examine the association between symptom endorsement and RTA protocol duration in service academy cadets...

Introduction The coronavirus disease 2019 (COVID-19) pandemic has adversely affected surgical training internationally. Laparoscopic surgery has a steep learning curve necessitating repetitive procedural practice. We evaluate the efficacy of short- and long-duration simulation training on participant skill acquisition to support the recovery of surgical training.  Methods A prospective, observational study involving 18 novice medical students enrolled in a five-week course. Nodal timed assessments involved three tasks: hoop placement, stacking of sugar cubes and surgical cutting...

In athletic populations, compression socks (CS) may improve exercise performance recovery. However, their potential to improve performance and/or recovery following exercise in non-athletic populations is unknown. Our study evaluated the effects of CS on exercise performance and recovery from a graded maximal treadmill test. Insufficiently active adults ( n = 10, 60% female, average physical activity ~60 minutes/week) performed two graded maximal exercise tests; one while wearing below-knee CS, and the other trial with regular socks (CON)...

CONTEXT: Paracanoeing is one of the adapted sports eligible for different motor impairments. The acute:chronic workload ratio (ACWR) is an index between acute and chronic training workload. However, no studies have analyzed this variable in paracanoeing, relating it with training recovery markers. OBJECTIVE: This study aimed to quantify the internal (session rating of perceived exertion) and external (distance traveled and total training time) training workloads in 4 experienced paracanoe athletes over 9 months and 5 canoeing events...

A growing number of studies utilizing wearable technologies are examining the influence of the autonomic nervous system (ANS) on intense training, recovery, and injury risk. Exercise biometric (EB) data were collected on collegiate, female soccer players during a preseason camp. One player sustained an anterior cruciate ligament (ACL) injury. Baseline anthropometric and EB data were compared to non-injured, position-matched teammates. All players had similar baseline testing. The injured athlete had a higher body mass index (BMI) and slower vision reaction time (RT)...

Background: Prescription of post-match or post-training recovery strategies in young soccer players is a key point to optimize soccer performance. Considering that the effectiveness of recovery strategies may present interindividual variability, scientific evidence-based recovery methods and protocols used in adults are possibly not applicable to young soccer players. Therefore, the current systematic review primarily aimed to present a critical appraisal and summary of the original research articles that have evaluated the effectiveness of recovery strategies in young male soccer players and to provide sufficient knowledge regarding the effectiveness of the recovery methods and strategies...

The aim of this study was to compare the acute responses to three time-matched exercise regimens. Ten trained adults (age, maximum oxygen consumption (VO2max ), and body mass index (BMI) = 25.9 ± 5.6 yr, 50.9 ± 5.4 mL·kg-1 ·min-1 , and 22.1 ± 1.8 kg·m-2 ) completed sprint interval training (SIT) requiring 14 × 5 s efforts with 35 s of recovery, high-intensity interval training (HIIT) consisting of 18 × 15 s efforts at ~90% of peak heart rate (HRpeak ) with 15 s of recovery, and vigorous continuous training (CT) consisting of 8...

BACKGROUND: The SARS-CoV-2 pandemic had a profound impact on surgical services, potentially having a detrimental impact on training opportunities. The aim of this global survey was to assess the impact of the COVID-19 crisis on surgical training and to develop a framework for recovery. METHODS: A cross-sectional, web-based survey was conducted. This was designed by a steering committee of medical educationalists and validated by a group of trainees before dissemination...

Exercise overproduces oxygen reactive species (ROS) and eventually exceeds the body's antioxidant capacity to neutralize them. The ROS produce damaging effects on the cell membrane and contribute to skeletal muscle damage. Selenium (Se), a natural mineral trace element, is an essential component of selenoproteins that plays an important role in antioxidant defense. The activity of the enzyme glutathione peroxidase (GPx), a highly-efficient antioxidant enzyme, is closely dependent on the presence of Se. These properties of Se may be potentially applicable to improve athletic performance and training recovery...

Trip-specific training improves the kinematics of trip-specific compensatory stepping response (CSR) in the laboratory and reduces prospectively-measured trip-related fall rates of middle age and older women. We examined whether one session of trip-specific perturbation training could improve recovery step kinematics in women with knee OA, a condition known to increase fall-risk. Seventeen women with self-reported, symptomatic knee OA (age 61.1±7.7 years, BMI 29.7±5.9 kg/m2 ) and 22 control women (age 59...

OBJECTIVE: Mental health self-direction, also known as self-directed care , involves an individual budget controlled by the participant with support from a specially trained recovery coach. The model under study here, implemented in a Medicaid behavioral health managed care context, allowed individuals to intentionally reduce mental health service use and apply cost savings as "Freedom Funds" to purchase a range of goods and services that are not typically considered mental health services to support recovery...

BACKGROUND: Individuals with stroke are at significant risk of falling. Trip-specific training is a targeted training approach that has been shown to reduce falls in older adults and amputees by enhancing the compensatory stepping response required to prevent a fall. Still, individuals with stroke have unique deficits (e.g. spasticity) which draws into question if this type of training will be effective for this population. OBJECTIVE: Evaluate if a single session of trip-specific training can modify the compensatory stepping response (trunk movement, step length/duration, reaction time) of individuals with chronic stroke...
