Article
This study aimed to investigate the effect of different set configurations on barbell trajectories during a series of power snatch sets. Ten strength-power athletes (height: 1.78 ± 0.09 m, body mass: 88.7 ± 14.3 kg, age: 28.9 ± 4.8 years) with at least 6 months of training experience performing the power snatch participated in this study. Each part...

Background Symptom burden remains a critical concern for individuals with non-small cell lung cancer (NSCLC) following the completion of treatment. The most common symptom clusters, dyspnea (shortness of breath) and fatigue, can contribute to physical decline, reductions in quality of life, and a higher risk of comorbidities and mortality. Dyspnea...

Force plates are commonly used when assessing vertical jumping performance but are not always affordable or practical tools for all testing situations. Twenty-four participants volunteered to take part in a study investigating the agreement between bilateral force plates and a new commercially available contact mat that records jump height, flight-...
Article
Altering set configurations during a resistance training program can provide a novel training variation that can be used to modify the external and internal training loads that induce specific training outcomes. To design training programs that better target the defined goal(s) of a specific training phase, strength and conditioning professionals n...

BACKGROUND: Defining quality of life (QOL) for individuals with disabilities is difficult, in part, because the construct of QOL is evolving and often misconceptualized by a focus on traditional outcome measurements (e.g., Short Form-36). In populations without disabilities, QOL is often narrowly defined in terms of function. The purpose of the stu...

Aging is associated with physiological declines, notably a decrease in bone mineral density (BMD) and lean body mass (LBM), with a concurrent increase in body fat, and central adiposity. Interest in women and aging is of particular interest partly as a result of gender specific responses to aging, particularly as a result of menopause. It is possib...

INTRODUCTION: Sarcopenia is the age-related loss of muscle and function. It is likely that losses in strength may occur prior to any detectible changes in lean mass. Muscle quality, a ratio of strength to lean mass, may be able to account for changes in both variables for early detection of sarcopenia. PURPOSE: To examine age- and gender-related di...
