The purpose of this literature review is to critique training studies that have examined the effects of jump-landing programmes on bone health parameters in premenopausal women. Activities such as jumping and hopping have been proposed to achieve the desired unusual or atypical strain distributions on the skeleton for women who are habitually inact...

Osteoporosis is a disease characterized by a reduction in the density and quality of bone leading to a weakness of the skeleton and associated increased risk of fracture [1]. The most common type of osteoporosis is termed primary osteoporosis and includes both postmenopausal and age-related osteoporosis, which involves the structural deterioration...

(1) Background: The aim of this study was to evaluate the effectiveness of a three-component nutrition, sleep, and physical activity (PA) program on cardiorespiratory fitness, body composition, and health behaviors in overweight airline pilots. (2) Methods: A parallel group study was conducted amongst 125 airline pilots. The intervention group part...

The purpose of this study was to quantify ground reaction forces across all planes of motion and determine the influence of instruction associated with vertical, forward and lateral hop landings in premenopausal women. Bilateral jump-landings have previously been the focus in this population with forces quantified primarily in the vertical directio...

The primary purpose of this study was to determine the effects of a 12-month quantified jump-landing program at clinically relevant bone sites in premenopausal women. Secondary measures of interest included; lower body explosive power, muscle reactivity, balance performance parameters and body composition. A longitudinal controlled trial was implem...

Background Jump landings have been quantified as a stimulus for bone health programs, however they may not be suitable for some populations. Currently, studies quantifying alternative types of lower body exercises are limited and no studies have quantified upper body exercises for inclusion in bone health programs. This study sought to quantify and...

Performing jump-landings may not be suitable for some individuals when programming for bone health. This study quantified a stomp exercise to determine its magnitude (body weight’s [BW’s]) and rate (body weights per second [BW∙s-1]) of strain among premenopausal women. Twenty healthy premenopausal women [Mean ±SD: 41.7±5.6y; 68.2±10.6kg; 165±5.5cm;...

Abstract Performing jump-landings may not be suitable for some individuals when programming for bone health. This study quantified a stomp exercise to determine its magnitude (body we...

Background: Currently jump-landing ground reaction forces have only been quantified in the vertical direction as a stimulus for bone development. This study quantified the full-spectrum of jump-landing force magnitudes (body weight's) and rates of strain (body weights per second) of bilateral multidirectional jumps (star jump and stride jump) with...

Jumps have been investigated as a stimulus for bone development, however effects of instruction, jump type and jump-landing techniques need investigation. This study sought to identify whether ground reaction forces (GRF’s) for bilateral vertical jumps (countermovement jumps and drop jumps) with reactive jump landings (i.e. jumping immediately afte...

Lifestyle behaviours of 183 women before and during pregnancy were investigated by retrospective questionnaire in the first few days postpartum. The threshold of cigarette smoking for a reduction in birth weight was exceeded at full term by 17% of the women, but only 1% exceeded a similar threshold for alcohol consumption. Consumption below the rec...
