The influence of different exercise intensities on kicking accuracy and velocity in soccer players.

Purpose: The aim of this study was to investigate the influence of different exercise intensities induced by a soccer specific protocol on kicking performance in soccer players.

Methods: Twelve semi-professional male soccer players participated in this study and performed maximal instep kicks before and after the implementation of an exercise protocol to determine the influence of different intensities upon kicking ball velocity and the target-hitting accuracy.

Results: Analysis of variance designs with repeated measures showed that maximal ball velocity was affected only after the most intense circuit ((6, 66) = 2.

A new physical performance classification system for elite handball players: cluster analysis.

The aim of the present study was to identify different cluster groups of handball players according to their physical performance level assessed in a series of physical assessments, which could then be used to design a training program based on individual strengths and weaknesses, and to determine which of these variables best identified elite performance in a group of under-19 [U19] national level handball players. Players of the U19 National Handball team (n=16) performed a set of tests to determine: 10 m (ST) and 20 m (ST) sprint time, ball release velocity (BRv), countermovement jump (CMJ) height and squat jump (SJ) height. All players also performed an incremental-load bench press test to determine the 1 repetition maximum (1RM), the load corresponding to maximum mean power (Load), the mean propulsive phase power at Load (PMP) and the peak power at Load (PMP).

Effects of knowing the task duration on players' pacing patterns during soccer small-sided games.

The aim of this study was to identify the influence of prior knowledge of exercise duration on players' pacing patterns during soccer small-sided games.

In the first game scenario, players were not informed how long they would be required to play the small-sided game and the activity was terminated after 20 min (Unknown Condition).

Work Role Perspectives of Clinical Instructors From Three Countries.

Background: Educational institutions partner with health facilities to provide clinical education, but the impact of these partnerships on clinical instructors is rarely examined.

Method: A cross-sectional study was used to obtain surveys from a convenience sample of clinical instructors (n = 135) working in Israel, Norway, and the United States. The Nursing Clinical Instruction Role Assessment Tool (N-CIRAT) was developed to elicit clinical instructors' perspectives on the importance and nature of their work roles.

Comparison of range of motion tests with throwing kinematics in elite team handball players.

The aim of this study was to compare the active and passive range of motion (ROM) of the glenohumeral external rotation with the maximal external rotation and throwing performance during different throws with different wind-up techniques in elite team handball players. Twenty-two elite team handball players participated in the study in which the maximal ball release velocity and maximal external rotation during standing, with run-up and jump throws with two types of wind-ups were measured together with the maximal active and passive glenohumeral ROM of the external rotation, lying supine on a bench. Higher maximal external rotation was found during the throws with the whip-like wind-up in comparison to circular-like wind-up throws together with a lower external rotation during the active ROM test.

Accumulation of FoxP3+ T regulatory cells in the tumor microenvironment of human colorectal adenomas.

Objectives: T regulatory cells (Tregs) play a critical important role for the occurrence and development of human tumors. Most human colorectal cancers (CRCs) develop from the preformed adenomas, this study is therefore designed to evaluate forkhead box P3 (FoxP3)+ Tregs in human colorectal adenomas.

Materials And Methods: FoxP3+ Tregs in human colorectal adenomas were evaluated with immunohistochemistry (IHC) and real-time PCR, and compared to CRCs and normal tissues.

Underestimation of Patient Breathlessness by Nurses and Physicians during a Spontaneous Breathing Trial.

Rationale: Breathlessness is a prevalent and distressing symptom in intensive care unit patients. There is little evidence of the ability of healthcare workers to assess the patient's experiences of breathing. Patient perception of breathing is essential in symptom management, and patient perception during a spontaneous breathing trial (SBT) might be related to extubation success.

A multiplex microsatellite set for non-invasive genotyping and sexing of the osprey ().

During the 1950s and 1970s the osprey () experienced a dramatic population crash and remains of conservation concern in several parts of the world. We isolated 37 microsatellite loci and assessed these in ospreys sampled in the UK and Norway (using mouth swabs/feathers). From 26 loci variable in four ospreys, we selected 13, combined these into two multiplex-PCR sets and included a sex-typing marker.

"Picking up the pieces" - Meanings of receiving home nursing care when being old and living with advanced cancer in a rural area.

Rural home nursing care is a neglected area in the research of palliative care offered to older cancer patients. Because access to specialized services is hampered by long distances and fragmented infrastructure, palliative care is often provided through standard home nursing services and delivered by general district nurses. This study aimed to illuminate the lived experience and to interpret the meaning of receiving home nursing care when being old and living with advanced cancer in a rural area in Norway.

Protective Effect of Regular Physical Activity on Depression After Myocardial Infarction: The HUNT Study.

Purpose: To study if physical activity within the recommended level over time was associated with risk of developing depression after the first myocardial infarction in older adults.

Methods: Men (n = 143) and women (n = 46) who had reached the age of 60 years in 2006-2008 who participated in the Nord-Trøndelag Health Study (HUNT1, 1984-1986; HUNT2, 1995-1997; HUNT3, 2006-2008) without any mental illness or cardiovascular disease at baseline in HUNT2 and who experienced their first myocardial infarction before HUNT3 were included. Based on the patterns of physical activity from HUNT1 to HUNT2, the sample was divided into 4 groups: persistently inactive, from active to inactive, from inactive to active, and persistently active.

Effect of Practicing Soccer Juggling With Different Sized Balls Upon Performance, Retention, and Transfer to Ball Reception.

The aim of this study was to investigate if making the skill acquisition phase more difficult or easier would enhance performance in soccer juggling, and if this practice has a positive intertask transfer effect to ball reception performance. Twenty-two adolescent soccer players were tested in juggling a soccer ball and in the control of an approaching ball at a pre, post and retention test. The participants were randomly divided in a small ball size and bigger ball size training group that both trained four times per week for 6 weeks.

Disability Pensions Among Young Adults in Vocational Rehabilitation.

Objectives: Lack of work-participation and early disability pensions (DP's) among young adults are increasing public health problems in most western European countries. The present study investigated determinants of early DP in young adults in vocational rehabilitation.

Methods: Data from 928 young adults (aged 18-40 years) attending a vocational rehabilitation program was linked to DP's recorded in the Norwegian Labor and Welfare Organization registries (1992-2010) and later compared to a group of 65 employees (workers).

Bilateral Asymmetry in Upper Extremities Is More Pronounced in Distal Compared to Proximal Joints.

The authors' aim was to compare spatial and temporal accuracy in proximal versus distal joints in upper extremities. Given the morphological differences in corticospinal and corticomotoneuronal projections for proximal and distal muscles, they hypothesized that bilateral asymmetry would be larger for distal than for proximal joints. Twelve participants performed isolated flexion-extension movements with the shoulders and index fingers.

Player Load, Acceleration, and Deceleration During Forty-Five Competitive Matches of Elite Soccer.

The use of time-motion analysis has advanced our understanding of position-specific work rate profiles and the physical requirements of soccer players. Still, many of the typical soccer activities can be neglected, as these systems only examine activities measured by distance and speed variables. This study used triaxial accelerometer and time-motion analysis to obtain new knowledge about elite soccer players' match load.

The effects of grip width on sticking region in bench press.

The aim of this study was to examine the occurrence of the sticking region by examining how three different grip widths affect the sticking region in powerlifters' bench press performance. It was hypothesised that the sticking region would occur at the same joint angle of the elbow and shoulder independent of grip width, indicating a poor mechanical region for vertical force production at these joint angles. Twelve male experienced powerlifters (age 27.
