Can transcranial direct current stimulation (tDCS) over the motor cortex increase endurance running performance? a randomized crossover-controlled trial.

Transcranial direct current stimulation (tDCS), a non-invasive brain stimulation technique, has been shown to increase exercise performance in strength and cycling studies but its effects on running endurance remain unclear. The objectives of this randomized sham-controlled crossover trial were to assess tDCS efficacy on submaximal treadmill running time to exhaustion (TTE). Forty-five healthy male runners aged between 18 and 32 years (mean maximal oxygen consumption: 46.

Snow sports-specific extension of the IOC consensus statement: methods for recording and reporting epidemiological data on injury and illness in sports.

The International Olympic Committee's (IOC) consensus statement on 'methods for recording and reporting of epidemiological data on injury and illness in sport' recommended standardising methods to advance data collection and reporting consistency. However, additional aspects need to be considered when these methods are applied to specific sports settings. Therefore, we have developed a snow sports-specific extension of the IOC statement to promote the harmonisation of injury and illness registration methods among athletes of all levels and categories in the different disciplines governed by the International Ski and Snowboard Federation (FIS), which is also applicable to other related snow sports such as biathlon, ski mountaineering, and to some extent, para snow sports.

Neurological conditions and community-based physical activity: physical therapists' belief and actions.

Introduction: Physical therapists (PTs) are key actors in physical activity (PA) promotion. However, it remains unclear whether PTs in community settings promote community-based PA such as adapted physical activity (APA) and adaptive sports (AS) to their patients with neurological conditions (NCs). The main purposes were to evaluate the beliefs PTs have of APA and AS, and to explore actions they undertake to promote it to their patients with NCs.

Reliability and Validity of Temporal Parameters during the Side Hop Test in Patients after Anterior Cruciate Ligament Reconstruction.

The side hop test (SHT) measures the number of jumps performed over 30 s. Although this measure has demonstrated its value in clinical practice, the temporal parameters of the SHT allow for a deeper analysis of the execution strategy. The aim of this study is to assess the reliability and construct validity of contact time parameters during the SHT recorded by a video analysis system in anterior cruciate ligament reconstructed (ACLR) patients.

Strength and activity of the protractor and retractor muscles of the asymptomatic dyskinetic scapula.

The role of scapular dyskinesis as a risk factor of shoulder injury has been largely discussed. However, most studies have focused on symptomatic patients and less is known on the asymptomatic dyskinetic scapula. Removing the confounding effects of the pathologies could contribute to better characterize the scapula dyskinesis.

What impact have the IOC medical consensus statements made on athlete health? A survey of medical commissions from National Olympic/Paralympic Committees and International Sports Federations.

Background: The International Olympic Committee (IOC) Medical and Scientific Commission has supported collating and sharing evidence globally by developing sports medicine consensus statements ('Statements''). Publishing the Statements requires substantial resources that must be balanced by use and impact on policy and practice. This study aimed to gain a better understanding of awareness and uptake of the Statements globally through a survey of the National Olympic Committees (NOC), National Paralympic Committees (NPC) and International Federations (IF).

Before hitting the slopes: athlete and staff perspectives on warm-up and activation in high-performance snowsports.

To explore warm-up and activation (W&A) practices in high-performance snowsports to describe their importance, application and potential improvements based on the perspectives of elite-level athletes and staff members. Qualitative study consisting of semistructured interviews with 13 international elite-level athletes, on-snow coaches, strength and conditioning coaches, sports physiotherapists and sports psychologists from different snowsports and subdisciplines: alpine skiing, freestyle skiing (park and pipe, aerials, moguls) and snowboarding (park and pipe, snowboard cross). The interviews were transcribed verbatim and analysed based on the principles of grounded theory.

Differences in Strength and Fatigue Resistance of Scapular Protractors and Retractors Between Symptomatic and Asymptomatic Dyskinesis.

Context: Scapular dyskinesis is a shoulder dysfunction that can be asymptomatic or associated with pain or weakness. Reduced strength and fatigue resistance of the scapular protractor and retractor muscles that stabilize the scapula might contribute to dyskinesis.

Objectives: To determine the strength and fatigue resistance profiles of participants with symptomatic or asymptomatic scapular dyskinesis and compare them with healthy control (HC) individuals using isokinetic assessment.

Design: Descriptive epidemiological study.

[Approach to the athlete with low back pain].

Low back pain is a common symptom in athletes, hindering their activity. The etiology is tightly linked to the type of sport, often a consequence of repetitive movements, high pressures and strain being applied to the spine and adjacent muscular and ligamentous structures and a high degree of activity. The diagnosis is the key and causes are usually not severe.
