[Physical activity of students: prevalence and profiles of associated risk behaviours].

More than 40% of students do not practice any PA. These results highlight the need for a better understanding to develop intervention strategies for students, based on new public health approaches. The contribution of social and physical environmental factors to changes in PA needs to be further explored.

Effects of a 12-week physical activities programme on sleep in female university students.

Lack of sleep is known to negatively affect adolescent's health and the links between regular physical activity and sleep are unclear.This pilot study investigated whether the regular practice of physical activities among sedentary female students would improve their sleep. Nineteen female students, identified as sedentary and having poor subjective sleep quality were assigned in two groups to a 12-week university physical activities programme in accordance with the recommendations of World Health Organisation (N = 10) or to a control condition (N = 9).

Methods And Results: Fourteen Lebanese young men from 18 to 30 years (mean age 22.6 years) participated in this study.

Geometric indices of hip bone strength in male professional soccer players.

Aim Of The Study: The aim of this study was to compare geometric indices of hip bone strength in male professional soccer players and controls.

Methods: Twenty-three male professional soccer players and 21 male sedentary subjects whose ages range between 18 and 30 years participated in this study. Weight and height were measured, and body mass index (BMI) was calculated.

DXA-based variables and osteoporotic fractures in Lebanese postmenopausal women.

Introduction: The aim of this study was to assess DXA-based variables (bone mineral density, bone mineral apparent density, compressive strength index of the femoral neck and trabecular bone score) in Lebanese postmenopausal women having presented a previous fracture.

Materials And Methods: One thousand Lebanese postmenopausal women between 45 and 89 years participated in this study. The women were recruited by advertisements offering bone mineral density measurements at a reduced cost.

Combined effects of sleep deprivation and strenuous exercise on cognitive performances during The North Face® Ultra Trail du Mont Blanc® (UTMB®).

This study investigated the effects of combined sleep deprivation and strenuous exercise on cognitive and neurobehavioral performance among long-distance runners completing one of the most difficult ultramarathons in the world. Seventeen runners participated. Each had a wrist-worn actigraph throughout the race to record their sleep time.

Geometric indices of hip bone strength in overweight and control elderly men.

Aim Of The Study: The aim of this study was to compare geometric indices of hip bone strength in overweight and control elderly men.

Methods & Results: This study included 16 overweight (Body mass index (BMI) > 25 kg/m2) elderly men (aged 65-84 years) and 38 age-matched controls (BMI < 25 kg/m2). Body composition and bone mineral density (BMD) were assessed by dual-energy X-ray absorptiometry (DXA).

Adult female football players have higher lumbar spine and hip bone mineral density than age- and body weight-matched controls.

Aim: The aim of this study was to compare lumbar spine, total hip, femoral neck, total forearm and 1/3 Radius bone mineral density (BMD) in young female football players and age- and body weight- matched female controls (aged 18 to 30 years).

Methods: This study included 18 female football players and 22 age- and body weight- matched sedentary females (aged 18 to 30 years). Weight and height were measured, and body mass index (BMI) was calculated.

Bone mineral content and density in obese, overweight and normal weight adolescent boys.

Aim Of The Study: The aim of this study was to compare bone mineral content (BMC), bone mineral density (BMD) and bone mineral apparent density (BMAD) in obese, overweight and normal weight adolescent boys.

Methods & Results: This study included 23 obese, 19 overweight and 25 normal weight adolescents (aged 14-20 years) boys. The three groups (obese, overweight and normal weight) were matched for age and maturation index.

Sleep restriction and degraded reaction-time performance in Figaro solo sailing races.

In solo offshore sailing races like those of the Solitaire du Figaro, sleep must be obtained in multiple short bouts to maintain competitive performance and safety. Little is known about the amount of sleep restriction experienced at sea and the effects that fatigue from sleep loss have on sailors' performance. Therefore, we assessed sleep in sailors of yachts in the Figaro 2 Beneteau class during races and compared response times on a serial simple reaction-time test before and after races.

Relative importance of lean mass and fat mass on bone mineral density in a group of Lebanese elderly men.

Validation of the Vivago Wrist-Worn accelerometer in the assessment of physical activity.

Background: Most accelerometers are worn around the waist (hip or lower back) to assess habitual physical activity. Wrist-worn accelerometers may be an alternative to the waist-worn monitors and may improve compliance in studies with prolonged wear. The aim of this study was to validate the Vivago® Wrist-Worn Accelerometer at various intensities of physical activity (PA) in adults.
