Clinical Evaluation Techniques for Injury Risk Assessment in Elite Swimmers: A Systematic Review.

Context: Evidence concerning a systematic, comprehensive injury risk assessment in the elite swimming population is scarce.

Objective: To evaluate the quality of current literature regarding clinical assessment techniques used to evaluate the presence and/or development of pain/injury in elite swimmers and to categorize objective clinical assessment tools into relevant predictors (constructs) that should consistently be evaluated in injury risk screens of elite swimmers.

Data Sources: PubMed, Embase, Scopus, CINAHL, SPORTDiscus, PEDro, and the Cochrane Library Reviews were searched through September 2018.

Traditional exercises do not have a significant impact on abdominal peak force in healthy young adults.

The abdominals are vital to activities of daily living, for the prevention of lumbar pathologies, and during sport performance. The purpose of this study was to determine if training without external resistance was a sufficient overload to improve abdominal strength as defined by peak force. Seventy-one healthy men and women (age 19-40 years) participated in the 11-week study.

The influence of fitness and body weight on preferred exercise intensity.

Purpose: The purpose of this investigation was to determine the individual and combined effects of aerobic fitness and body weight on physiological responses, perceived exertion, and speed variables during self-selected steady-state treadmill (TM) walking in 60 healthy college-age women.

Methods: The women were placed into one of four categories based on body mass index (BMI) and fitness level, assessed by a graded TM test. Subjects walked continuously on a TM at a self-selected pace for 15 min at a 2.

GONG Observations of Solar Surface Flows.

Doppler velocity observations obtained by the Global Oscillation Network Group (GONG) instruments directly measure the nearly steady flows in the solar photosphere. The sun's differential rotation is accurately determined from single observations. The rotation profile with respect to latitude agrees well with previous measures, but it also shows a slight north-south asymmetry.

The Solar Acoustic Spectrum and Eigenmode Parameters.

The Global Oscillation Network Group (GONG) project estimates the frequencies, amplitudes, and linewidths of more than 250,000 acoustic resonances of the sun from data sets lasting 36 days. The frequency resolution of a single data set is 0.321 microhertz.

The Global Oscillation Network Group (GONG) Project.

Helioseismology requires nearly continuous observations of the oscillations of the solar surface for long periods of time in order to obtain precise measurements of the sun's normal modes of oscillation. The GONG project acquires velocity images from a network of six identical instruments distributed around the world. The GONG network began full operation in October 1995.
