Moderate and Vigorous Physical Activity Intensity Cut‐Points for Hip‐, Wrist‐, Thigh‐, and Lower Back Worn Accelerometer in Very Old Adults Scand. J. Med. Sci. Sports (IF 3.5) Pub Date : 2025-01-04
Mathias Skjødt, Jan Christian Brønd, Mark A. Tully, Li‐Tang Tsai, Annemarie Koster, Marjolein Visser, Paolo CaserottiPhysical activity (PA) reduces the risk of negative mental and physical health outcomes in older adults. Traditionally, PA intensity is classified using METs, with 1 MET equal to 3.5 mL O2·min−1·kg−1. However, this may underestimate moderate and vigorous intensity due to age‐related changes in resting metabolic rate (RMR) and VO2max. VO2reserve accounts for these changes.

Validity of Four Consumer‐Grade Optical Heart Rate Sensors for Assessing Volume and Intensity Distribution of Physical Activity Scand. J. Med. Sci. Sports (IF 3.5) Pub Date : 2024-11-07
Michael Neudorfer, Devender Kumar, Jan David Smeddinck, Stefan Tino Kulnik, Josef Niebauer, Gunnar Treff, Mahdi SarebanConsumer‐grade optical heart rate (HR) sensors emerged as promising tools to monitor volume and intensity of physical activity (PA). However, no validation study of optical HR sensors included recent comprehensive validation recommendations, required for facilitating usage for medical purposes. Validity of HR data measured with four consumer‐grade optical sensors, the wrist‐worn Garmin Venu 2S and

Association of Objectively Measured Sedentary Behavior With Arterial Stiffness: Findings From the Nijmegen Exercise Study. Scand. J. Med. Sci. Sports (IF 3.5) Pub Date : 2024-11-01
Koen M van der Sluijs,Esmée A Bakker,Thijs P Kerstens,Niels A Stens,Iris A de Koning,Jos Thannhauser,Afrah E F Malik,Koen D Reesink,P M Nabeel,Kiran V Raj,Jayaraj Joseph,,Thijs M H Eijsvogels,Dick H J ThijssenSedentary behavior (SB) may affect arterial stiffness, preceding the development of cardiovascular disease. We investigated the association of objectively measured SB with arterial stiffness. We also investigated factors that affected this association. We recruited adult volunteers and measured SB with thigh-worn accelerometery for 24 hrs/day for eight consecutive days. Central (carotid-femoral pulse

High Incidence of Injuries Among Adolescent Elite Skiers—A 5‐Year Cohort Study Scand. J. Med. Sci. Sports (IF 3.5) Pub Date : 2024-10-29
Ida Lindman, Adad Baranto, Cecilia Agnvall, Josefin AbrahamsonCompetitive skiing has gained increasing popularity among adolescent, yet it comes with injury risks. The aim was to determine injury incidence, type and time of injury, localization, and diagnosis, among adolescent competitive skiers (alpine, cross‐country, ski‐cross, mogul), and to compare between skiing discipline, sex, and high school year. All students (n = 190) enrolled in a ski high school from

A Qualitative Analysis to Determine the Critical Features of a Frontside Bottom Turn in Professional Surfing Scand. J. Med. Sci. Sports (IF 3.5) Pub Date : 2024-10-29
John W. Whitting, Ruben Brinsmead, James R. Forsyth, Jennifer Hollier, Zachary J. Crowley‐McHattanSurfing bottom turns underpin the quality of subsequent maneuvers, and surfing performance overall. Despite this, no study has investigated coaching cues to determine their association with performance. This study investigated the frontside bottom turn, to identify critical features associated with quality performance, and second to determine whether any of these features could predict whether a surfer

Intra‐Rater Reliability of Panoramic Ultrasound Imaging for Determining Quadriceps Muscle Cross‐Sectional Area in Middle‐Aged and Elderly Adults Scand. J. Med. Sci. Sports (IF 3.5) Pub Date : 2024-10-29
Brian Sørensen, S. Peter Magnusson, Christian Couppé, Charlotte Suetta, Finn E. Johannsen, Morten Tange Kristensen, Per AagaardPanoramic ultrasound (US) is an extended field‐of‐view (EFOV) imaging technique that enables visualization of large‐scale skeletal muscles. This technique has previously been found to produce valid and reliable quantifications of muscle morphology in primarily young male subjects. The purpose was to investigate the intra‐rater between‐session test–retest reliability of panoramic US imaging for determining

Heinonen, Jorma Viikari, Tapani Rönnemaa, Harri Niinikoski, Olli Raitakari, Sari Stenholm, Katja PahkalaThere is scarcity of studies using device‐based measures to examine how relationship and parenthood transitions modify 24‐h movement behaviors. This study examined how the composition of 24‐h movement behaviors changes during these life transitions. Young adults (n = 170, mean age 25.6 years, SD 0.6) from the Special Turku Coronary Risk Factor Intervention Project (STRIP) wore wrist‐worn accelerometers

The Effect of Blood Flow Restriction Exercise Prior to Total Knee Arthroplasty on Postoperative Physical Function, Lower Limb Strength and Patient‐Reported Outcomes: A Randomized Controlled Trial Scand. J. Med. Sci. Sports (IF 3.5) Pub Date : 2024-10-27
Stian Langgård Jørgensen, Per Aagaard, Marie Bagger Bohn, Peter Hansen, Per Møller Hansen, Carsten Holm, Louise Mortensen, Mette Garval, Lisa Urup Tønning, Inger MechlenburgThe trial aimed to examine the effect of eight weeks preoperative low‐load blood flow restricted resistance training (BFR‐RT) on physical function, lower limb strength, and patient‐reported outcomes in knee OA patients 3 and 12 months after total knee arthroplasty (TKA) compared with preoperative usual care. An assessor blinded randomized controlled trial (RCT) was conducted. Eighty‐six patients scheduled

Inter‐Individual Variability in Muscle Fiber–Type Distribution Affects Running Economy but Not Running Gait at Submaximal Running Speeds Scand. J. Med. Sci. Sports (IF 3.5) Pub Date : 2024-10-27
Wannes Swinnen, Eline Lievens, Wouter Hoogkamer, Friedl De Groote, Wim Derave, Benedicte VanwanseeleRunning economy is an important determinant of endurance running performance, yet insights into characteristics contributing to its inter‐individual variability remain limited. Although slow‐twitch muscle fibers are more energy‐efficient than fast‐twitch fibers during the (near‐)isometric contractions common during submaximal running, current literature lacks a consensus on whether a relationship between
