Objectives This study evaluates the effect of two different worksite physical-activity interventions on neck–shoulder symptoms, together with perceived work ability and sick leave among office workers. Methods An examiner-blinded randomized controlled trial was conducted 549 workers allocated to one three intervention groups: specific resistance training (SRT) region (N=180), all-round physical exercise (APE) (N=187), which acted as a reference group, informed about general health-promoting...

Purpose: The objective of this study is to investigate the effect three different workplace interventions on long-term compliance, muscle strength gains, and neck/shoulder pain in office workers. Methods: A 1-yr randomized controlled intervention trial was done with groups: specific resistance training (SRT, n = 180), all-round physical exercise (APE, 187), reference (REF, 182) general health counseling. Physical tests were performed questionnaires answered at pre-, mid-, postintervention....

Objective: To investigate the effect of two contrasting physical activity worksite interventions versus a reference intervention (REF) on various health outcomes. Methods: A 1-year randomized controlled trial was conducted with specific resistance training (SRT), all-round exercise (APE), and REF. Results: SRT APE compared REF showed significant reductions in systolic blood pressure (∼6 mm Hg), body fat percentage (∼2.2 fat%), as well shoulder back pain (∼30% reduction duration). Muscle...

The purpose of the study was to elucidate role expertise on muscle synergies involved in bench press. Ten expert power lifters ( EXP ) and nine untrained participants UNT completed three sets eight repetitions at 60% repetition maximum Muscle were extracted from surface electromyography data 21 press cycles using non‐negative matrix factorization algorithm. synergy activation coefficient represents relative contribution overall activity pattern, while vector weighting each within synergy....

ABSTRACT This study investigated the variation in freely chosen pedal rate between subjects and its possible dependence on percentage myosin heavy chain I (%MHC I) m. vastus lateralis, maximum leg strength power, as well efficiency. Additionally, hypothesis was tested that a positive correlation exists MHC efficiency at pre‐set rates but not rate. Twenty males performed cycling low high submaximal power output (∼40 70% of which oxygen uptake (VO 2max ) attained 80 r.p.m.) with (61, 88, 115...

To investigate the effects of heavy strength training on mean power output in a 5-min all-out trial following 185 min submaximal cycling at 44% maximal aerobic well-trained cyclists. Twenty cyclists were assigned to either usual endurance combined with [E+S; n=11 (♂=11)] or only [E; n=9 (♂=7, ♀=2)]. The performed by E+S consisted four lower body exercises [3 × 4-10 repetition maximum (RM)], which twice week for 12 weeks. increased 1 RM half-squat (P≤0.001), while no change occurred E. led...

The degree of perceived enjoyment performed physical activity may be a key aspect with relevance for the effort to get people physically active. Spinning, or indoor cycling, is widespread that can in group individually. effect element on spinning remains unclear. Therefore, purpose present study was test hypothesis greater during exercise session as compared Twenty recreationally active persons (56 ± 6 years, 1.74 0.09 m, 81.0 14.7 kg, and BMI 26.5 3.7) 44-min individual instructor-led...

J Strength Cond Res 30(7): 1948–1959, 2016—The ability to perform forceful contractions has important implications in sports performance activities daily living. However, there is a lack knowledge adaptations intermuscular coordination after strength training. The purpose this study was therefore assess synergies before Thirty untrained...

It remains unclear why humans spontaneously shift from walking to running at a certain point during locomotion gradually increasing velocity. We show that calculated walk-to-run transition stride frequency (70.6 ± 3.2 strides min-1) agrees with (70.8 3.1 predicted the two frequencies applied treadmill and freely chosen velocities frequencies. The agreement is based on Bland Altman's statistics. found no essential mean relative difference between frequencies, i.e. -0.5% 4.2%, as well limits...

Seabed material properties. Description geometry pile. Simulations presented in show that for typical North Sea conditions depth will be 0.3 times diameter periods larger waves, is a...

It is not known whether the seated or standing position favours performance during intensive bouts of uphill cycling. The following hypotheses were therefore tested: (1) results in better at a high power output, while (2) best moderate output. We also assessed seated-standing transition intensity, above which cycling should be superseded by for maximization performance. Ten male cyclists (mean age 27 years, s = 3; height 1.82 m, 0.07; body mass 75.2 kg, 7.0; VO2max 70.0 ml.kg(-1).min(-1),...

It was tested whether a marathon completed faster by applying scientifically based rather than freely chosen nutritional strategy. Furthermore, gastrointestinal symptoms were evaluated. Nonelite runners performed 10 km time trial 7 weeks before Copenhagen Marathon 2013 for estimation of running ability. Based on the time, divided into two similar groups that eventually should perform strategies. Matched pairs design applied. Before marathon, paired their prerace Runners strategy (n = 14;...
