Introduction: The VO[subscript 2] max test is the gold standard measure for aerobic fitness. A standardised treadmill protocol was developed years ago for individuals with Down syndrome but with variations in terms of starting speed, load increases and time spent at each stage. However, we realised that the most widely used protocol for adults…

The flexion relaxation ratio (FRR) of the lumbar extensor muscles is often assessed in experimental and clinical studies. This study evaluated within- and between-session test--retest reliability and measurement error for different FRR formulations. Participants completed two identical data collection sessions 1-week apart. Spine flexion and…

Background: While people with intellectual disabilities tend to refrain from physical activity, outdoor physical activity programs increase motivation to engage in physical activity. Method: Eighty adults with intellectual disabilities participated in a 12-month outdoor physical activity program. Attendance was used to assess feasibility. Aerobic…

Purpose: The aim of this study was to examine the physiological demands of trampolining, in comparison with treadmill running, using a larger sample size and a wider range of physiological measures, than had been reported in the previous research. Method: Twenty-three healthy adults completed three, three-minute exercise bouts on both a trampoline…

This study compared criterion to minimally invasive, practical measures of core (T[subscript c]) and skin (T[subscript sk) temperature during 30 min of moderate-intensity cycle exercise in a heat chamber (35°C, 60% rH). T[subscript c] was monitored using a core temperature pill (T[subscript c](Pill))] and tympanic thermometer (T[subscript c(Tymp))…

Accurate determinations of individuals' one-repetition maximum (1RM) are critical when evaluating the effectiveness of an exercise intervention involving progressive resistance training (RT). Traditional ("bottom-up"; BT) testing methods involve progressions from low to maximal loads and are commonly used in clinical and laboratory…

Purpose: This study compared the acute effects of two different resistance training methods on heart rate variability, blood pressure, and rating of perceived exertion in patients with liver cirrhosis. Methods: Ten patients with Child-Pugh A (seven women and three men) participated in two experimental sessions, in random order: The traditional set…

Sleep deprivation in healthy adults has been associated with disrupted autonomic nervous system function, which in turn has been linked to cardiovascular health. High-intensity interval exercise (HIIE) may affect both sleep and cardiac autonomic modulation. Purpose: To investigate the impact of acute partial sleep deprivation on autonomic cardiac…

Background: The cardiovascular disease (CVD) risk is high in adults with intellectual disabilities. This CVD risk can potentially be decreased with a resistance training (RT) programme at vigorous intensity, following previous research on successful High-Intensity Training programmes. Our aim was to explore the feasibility of a vigorous…

Background: Physical activity is widely known to positively affect serum lipids. Yet, no study has utilized a path analysis methodology, which is more efficacious at analyzing complex relationships than simple regressions, to incorporate the cumulative effects of physical activity and waist circumference on lipids. Purpose: Our objective was to…

Electronic pedometers are relatively inexpensive devices to monitor physical activity. To assess physical activity intensity using a pedometer, establishing the relationship between step-rate measured by a pedometer and the rate of oxygen uptake (VO[subscript 2]) is needed. This study examined the step-counting accuracy of the NL-2000i electronic…

Purpose: The purpose of this study was to evaluate the agreement of five commercially available accelerometers in estimating energy expenditure while performing an acute bout of high-intensity functional training (HIFT). Methods: Participants (n = 47; average age: 28.5 ± 11.6 years) consisted of recreationally active, healthy adults. Each…

Background: Perception of exertion is essential for self-regulation in sports. The ability to rate perceived exertion (RPE) is regarded as psychophysiological competence, although cognitive components of RPE are largely unknown. The present study tested the hypothesis that cognitive processing speed, perseveration and figural fluency correlate…

To examine the reproducibility of three measurement techniques used to determine creatine kinase, interleukin-6 and high-sensitivity C-reactive protein, 50 participants had blood samples taken on two occasions. Fingertip plasma samples were analysed using the Reflotron for CK determination. Venous blood samples collected into serum separator tubes…

The aim of this study is to investigate the influence of lower and upper extremity strength on shot styles in tennis. 54 males and 19 females training regularly as experimental group and 24 male and 9 female volunteers as control group participated in the study. 24 training sessions were applied to the experimental group participants. Every week…
