Six-minute walk test in moderate to severe heart failure with preserved ejection fraction: Useful for functional capacity assessment?
2015
Despite improvements in medical treatment and prevention, heart failure (HF) remains a major cause of morbidity and mortality worldwide [1]. Currently, HF with preserved ejection fraction (HFpEF) has become the most prevalent form of HF in elderly patients [2,3]. The cardinal features in HF, aside from left ventricular systolic function, are exertional dyspnea and reduced aerobic capacity. Although the most accurate expression of exercise tolerance and severity in HF is measured by peak oxygen uptake (peak VO2), its assessment is not widely available in daily clinical practice. This work was supported in part by grants from: Sociedad Española de Cardiología: Investigación Clínica en Cardio…
Association between Actual and Perceived Motor Competence in School Children
2020
(1) Background: The association between actual and perceived motor competence (MC) is one of the underlying mechanisms that influence the practice of physical activity. This study mainly aimed to analyze the structure and correlations between actual and perceived MC in schoolchildren and to compare actual and perceived MC between girls and boys. (2) Methods: A total of 467 fifth and sixth graders (43.9% girls, M = 11.26, SD = 0.70) participated. Actual and perceived MC were assessed. To examine the proposed four factor models, structural equation models (factor analyses, latent correlations, invariance testing for gender) were conducted. Student t-test for independent samples was used to co…
Motor competence, perceived physical competence, physical fitness, and physical activity within Finnish children
2019
The purpose of this study was to investigate reciprocal relationships among students’ motor competence (MC) (leaping, throwing, catching, jumping skills), perceived physical competence, health‐related fitness (HRF) (20 m shuttle run, push‐up, abdominal muscles endurance tests) and objectively measured moderate‐to‐vigorous physical activity (MVPA). Participants included 422 Grade 5 Finnish children (246 girls). Two separate structural equation models investigated paths (a) from MC through both perceived physical competence and HRF to MVPA, and (b) from MVPA through both perceived physical competence and HRF to MC. Model 1 demonstrated an indirect path from MC through HRF to MVPA and a direct…
Adiposity, physical activity and neuromuscular performance in children
2016
We investigated the associations of body fat percentage, objectively assessed moderate-to-vigorous physical activity (MVPA), and different types of physical activity assessed by a questionnaire with neuromuscular performance. The participants were 404 children aged 6–8 years. Body fat percentage (BF%) was assessed using dual-energy x-ray absorptiometry and physical activity by combined heart rate and movement sensing and a questionnaire. The results of 50-metre shuttle run, 15-metre sprint run, hand grip strength, standing long jump, sit-up, modified flamingo balance, box and block, and sit-and-reach tests were used as measures of neuromuscular performance. Children who had a combination of…

Long-term leisure-time physical activity and other health habits as predictors of objectively monitored late-life physical activity – A 40-year twin …
2018
AbstractIMPORTANCEModerate-to-vigorous physical activity (MVPA) in old age is an important indicator of good health and functional capacity enabling independent living.OBJECTIVETo investigate whether physical activity and other health habits at ages 31-48 years predict objectively measured MVPA decades later.DESIGN, SETTING, AND PARTICIPANTSThis prospective twin cohort study in Finland comprised 616 individuals (197 complete twin pairs, including 91 monozygotic pairs, born 1940-1944), who responded to baseline questionnaires in 1975, 1981, and 1990, and participated in accelerometer monitoring at follow-up (mean age, 73 years).EXPOSURESPrimary exposure was long-term leisure-time physical ac…
The Effects of Cold Exposure on Leukocytes, Hormones and Cytokines during Acute Exercise in Humans
2014
The purpose of the study was to examine the effects of exercise on total leukocyte count and subsets, as well as hormone and cytokine responses in a thermoneutral and cold environment, with and without an individualized pre-cooling protocol inducing low-intensity shivering. Nine healthy young men participated in six experimental trials wearing shorts and t-shirts. Participants exercised for 60 min on a treadmill at low (LOW: 50% of peak VO2) and moderate (MOD: 70% VO2peak) exercise intensities in a climatic chamber set at 22°C (NT), and in 0°C (COLD) with and without a pre-exercise low-intensity shivering protocol (SHIV). Core and skin temperature, heart rate and oxygen consumption were col…
An age-adapted plyometric exercise program improves dynamic strength, jump performance and functional capacity in older men either similarly or more …
2020
Power declines at a greater rate during ageing and is more relevant for functional deterioration than either loss of maximum strength or muscle mass. Human movement typically consists of stretch-shortening cycle action. Therefore, plyometric exercises, using an eccentric phase quickly followed by a concentric phase to optimize power production, should resemble daily function more than traditional resistance training, which primarily builds force production capacity in general. However, it is unclear whether older adults can sustain such high-impact training. This study compared the effects of plyometric exercise (PLYO) on power, force production, jump and functional performance to tradition…
Comparison of post-activation performance enhancement (PAPE) after isometric and isotonic exercise on vertical jump performance.
2021
Purpose This study aimed to compare the post-activation performance enhancement (PAPE) induced by isometric and isotonic exercise on vertical jump performance. Methods 18 healthy trained men (25.8±2.7 years; 78.4±8.2 kg; 175.7±6.1 cm; 25.4±1.8 BMI; 126.72±10.8 kg squat 1-RM) volunteered for this study. They randomly performed two different PAPE protocols: Isotonic squats (ISOTS), which consisted of 2 sets of 3 repetitions at 75% of one-maximum repetition (1-RM); and isometric squats (ISOMS), which consisted of 2 sets of 4 seconds of submaximal (75% of 1-RM) isometric contraction at 90°-knee flexion. Countermovement jump (CMJ) height was tested at baseline and 4 minutes after each condition…
Comparison of blood lactate and perceived exertion responses in two matched time-under-tension protocols.
2019
PurposeThe aim of this study was to compare the concentration of blood lactate [bLa-] and the subjective perception of exertion of trained men in a moderate repetition protocol (MRP) versus a high repetition protocol (HRP) equated for time under tension.MethodsA sample of 40 healthy young men (aged, 23.2 ± 4.0 years; height, 177.3 ± 7.0 cm; BMI, 24.3 ± 2.2) performed two sessions of 8 sets of bicep curls with a one-week recovery interval between the trials. In the HRP protocol, 20 repetitions were performed with a cadence of 2 seconds of eccentric and 1 second of concentric, while in the MRP protocol 10 repetitions were performed with 4 seconds of eccentric and 2 seconds of concentric.
