Characterizing Relationships with Exercise Partners: Communication, Closeness, and Performance

Hill CR, Max EJ, Wittenbaum GM and Feltz DL

Article Type: Original Research | First Published: June 05, 2020

Social influence research in exercise has highlighted the motivation-boosting potential of working out with an exercise partner or group, but to the authors’ knowledge there has been no research to date characterizing the typical dyadic exercise relationship, which is an interpersonal relationship that includes regular co-exercise. If exercise partners are motivational, then characterizing their relationship is important. A sample of 555 undergraduates were administered a survey, 383 of whom m...

Article Type: Research Article | First Published: May 16, 2020

Deterioration of body composition with advancing age is related to functional decline. This study examined the effects of a novel progressive exercise training program on body composition in individuals > 70 y, at risk of losing functional independence. Aging is associated with significant changes in body composition. Evidence from the Baltimore Longitudinal Aging Study (BLAS) demonstrates Fat Free Mass (FFM) increases up to the 3rd decade of life, after which it remains relatively stable until ...

Factors that Influence Injuries Occurrence in Jiu-Jitsu Competitors

Tulio Fernandes de Almeida and Angelica Rodrigues de Araujo

Article Type: Research Article | First Published: April 29, 2020

The Brazilian Jiu-Jitsu (BJJ) is known for its efficiency and competitiveness, the modality has shown an increase in the practitioner’s number and international level competitions, leading to worldwide popularization. Even with worldwide success and recognition, the number of studies on the modality did not follow this growth, which makes it difficult to categorize the sport and identify the factors related to injuries, which is essential to promote and plan interventions aiming at injury prev...

Mahzad Teimourian, Hoseyn Fatolahi and Hasan Mateenhomaei

Article Type: Original Article | First Published: February 22, 2020

Each exercise mode can lead to a specific effect. On the other hand, herbal supplements increase the effects of exercise. Yet the interactive effect of exercise mode and Ursolic Acid (UA) on the Brown Adipose Tissue (BAT) has not been well explored. The aim of the present study was to investigate the effect of 12-week Aerobic Training (AT), Resistance Training (RT), and High Intensity Interval Training (HIIT) along with UA supplementation on muscle FNDC5 and adipose tissue UCP1 gene expression a...

Torque and Electrical Activation of the Rectus Femoris Muscle at Distinct Joint Angles: A Case Study

Anelize CINI, Francesca SONDA, Izabel de Almeida PAZ, Ana Paula Janner ZANARDI and Grazielle Martins GELAIN

Article Type: Case Report | First Published: February 21, 2020

The angulation of knee and hip joints affect isometric contractions of Rectus Femoris muscle (RF) during knee extension. Literature states that torque-angle relationship depends on muscle length and neuromuscular electrical activation. However, it is still not clear whether the maximum neuromuscular activation changes concomitantly with the change in the joint angles considering the presence of muscle shortening. We present a case study in which we analyzed changes in neuromuscular activation an...

A Novel Oblique Impact Test Rig for Testing Helmet

Daniel E Abram, Adrian Wikarna, Farid Golnaraghi and G Gary Wang

Article Type: Research Article | First Published: February 13, 2020

In this work, a new test rig is introduced to assess various head impact scenarios on different types of helmets. The test rig is a free-fall system where a helmeted headform is suspended instead of being placed on a basket frame and detaches from the system before the impact allowing an unrestricted motion. The proposed testbed showed to be effective in performing helmet impact tests at different angles. The test rig is particularly effective in tests at steep anvil angles, such as 15°, which ...

Systematization of Functional Training Sessions to Benefit Physical Fitness for Daily Activities in Older People

Antonio Gomes de Resende-Neto and Marzo Edir Da Silva-Grigoletto

Article Type: Editorial | First Published: February 10, 2020

Tools applied today in the Functional Training (FT) have long been used in general fitness programs, but systematic use and scientific interest are recent phenomena. Thus, there are many methodological conflicts and divergences in the prescriptions of this method. For example, some studies have associated FT with the use of instability in many exercises, while others use unstable bases in a small portion of training, or simply do not use. Thus, there is still an absence of a systematic FT model ...

Article Type: Research Article | First Published: November 09, 2019

Menstrual disorder is a risk factor for stress fracture. Stress fractures impede running activity in female long-distance runners. However, the bone metabolism of female long-distance runners, and its relationship with bone quality, are not understood. We examined the characteristics of bone metabolism and bone quality in female long-distance runners with menstrual disorder. Sixteen female university long-distance runners and 31 young female non-athlete volunteers were enrolled. Self-reported me...

DE Lankford, FACSM, Jake T Bartschi, Keegan Huntsman, Lex Gidley, Tyler Hook and Yilin Wu

Article Type: Research Article | First Published: November 04, 2019

The aim of the study is to validate two high-incline Graded Exercise Tests (GXT) that could be used as alternatives to the Bruce protocol to obtain VO2max values for college-aged individuals who may not be accustomed to running on a treadmill. Maximal oxygen uptake (VO2max) assesses the upper limit of an individual's ability to consume and utilize oxygen during intense, or maximal exercise, commonly accepted as a reliable indicator of cardiorespiratory health. Among all the existing protocols, G...

Limbus Vertebra and Low Back Pain: A Case Report and Review of Literature

Man R Shim, MD

Article Type: Case Report | First Published: October 14, 2019

Limbus vertebra is marginal interosseous herniation of the nucleus pulposus. It is generally considered to be an incidental finding without any symptoms unless posterior herniation causes nerve compression. However, recent findings have suggested limbus vertebra may be associated with a specific gene and intervertebral disk degeneration. This article reports a case of a 40-year-old male patient with limbus vertebra, intervertebral disk degeneration, and low back pain, followed by a comprehensive...

Peter S Micalos, Sokcheon Pak, Jack Cannon, Mathew Hale and Byung-Soo Koo

Article Type: Original Article | First Published: May 29, 2019

Repeat performance of the peak isometric muscle torque was sustained following a 20-min acupuncture procedure compared to a decline in the control group following a 20-min rest procedure. Differences between groups might be associated with acute acupuncture procedure and acquired performance bias. The procedure of needle acupuncture requires the insertion and manipulation of a fine needle at selected acupoints on the body to induce therapeutic effects. Acupuncture is widely recognised as a treat...
