The Effects of Cold Water Immersion and Active Recovery on Molecular Factors That Regulate Growth and Remodeling of Skeletal Muscle After Resistance Exercise
(Peer reviewed; Journal article, 2020)Regular postexercise cooling attenuates muscle hypertrophy, yet its effects on the key molecular factors that regulate muscle growth and remodeling are not well characterized. In the present study, nine men completed two ... -
Effects of exceeding stroke frequency of maximal effort on hand kinematics and hand propulsive force in front crawl
(Peer reviewed; Journal article, 2020)This study aimed to assess kinematic and kinetic changes in front crawl with various stroke frequency (SF) conditions to investigate why swimming velocity (SV) does not increase above a certain SF (SFmax). Eight male ... -
Effects of exercise training on carotid intima-media thickness in patients with type 2 diabetes and coronary artery disease. Influence of carotid plaques
(Journal article; Peer reviewed, 2016-01-22)Background: Carotid intima-media thickness (cIMT) holds prognostic information for future cardiovascular disease and is associated with the extent of coronary atherosclerosis. We investigated the effect of exercise on cIMT ... -
Effects of heavy strength training on running performance and determinants of running performance in female endurance athletes
(Journal article; Peer reviewed, 2016-03-08)Purpose: The purpose of the current study was to investigate the effects of adding strength training to normal endurance training on running performance and running economy in well-trained female athletes. We hypothesized ... -
Effects of high and low training volume with the Nordic hamstring exercise on hamstring strength, jump height, and sprint performance in female football players: A randomised trial
(Peer reviewed; Journal article, 2022)The evidence-based hamstring strengthening programme for prevention of hamstring injuries is not adopted by football teams because of its high training volume. This study on female football players investigated if high-volume ... -
Effects of High-Intensity Interval Training and Isoinertial Training on Leg Extensors Muscle Function, Structure, and Intermuscular Adipose Tissue in Older Adults
(Peer reviewed; Journal article, 2019)We compared the effects of aerobic high-intensity training (HIT) and isoinertial resistance training (IRT) on the strength, mass, architecture, intermuscular adipose tissue (IMAT) quality, and neuromuscular activation of ... -
Effects of in-season strength maintenance training frequency in professional soccer players
(Journal article; Peer reviewed, 2011-10)The aim of the present study was to examine the effect of in-season strength maintenance training frequency on strength, jump height, and 40-m sprint performance in professional soccer players. The players performed the ... -
Effects of increased loading on in vivo tendon properties: a systematic review
(Journal article; Peer reviewed, 2015-09)Introduction: In vivo measurements have been used in the past two decades to investigate the effects of increased loading on tendon properties, yet the current understanding of tendon macroscopic changes to training is ... -
Effects of Perioperative Nonsteroidal Anti-inflammatory Drug Administration on Soft Tissue Healing: A Systematic Review of Clinical Outcomes After Sports Medicine Orthopaedic Surgery Procedures
(Peer reviewed; Journal article, 2019)Background: The effects of perioperative nonsteroidal anti-inflammatory drugs (NSAIDs) on soft tissue healing in humans have yet to be established. Purpose: To systematically review the literature addressing the effects ... -
Effects of physical activity on schoolchildren's academic performance : The Active Smarter Kids (ASK) cluster-randomized controlled trial
(Journal article; Peer reviewed, 2016-09-07)Objective: To investigate the effect of a seven-month, school-based cluster-randomized controlled trial on academic performance in 10-year-old children. Methods: In total, 1129 fifth-grade children from 57 elementary ... -
Effects of Reducing Sedentary Time on Glucose Metabolism in Pakistani Immigrant Men
(Journal article; Peer reviewed, 2014-04)Purpose: This study aimed to examine the association between changes in objectively measured overall physical activity (PA) and changes in fasting and postprandial plasma insulin, C-peptide, and glucose concentrations in ... -
Effects of school-based physical activity interventions on mental health in adolescents: The School in Motion cluster randomized controlled trial
