However, limited data exist on performance under free-living conditions.This study aimed 1) compare effects speed body mass index (BMI) step count accuracy five different accelerometer-based monitors a pedometer during treadmill walking, 2) in environment, 3) counts three...
High-intensity functional training (HIFT) is a new modality that merges high-intensity exercise with (multijoint) movements. Even though others exist, CrossFit has emerged as the most common form of HIFT. Recently, several reports have linked to severe injuries and/or life-threatening conditions, such rhabdomyolysis. Empirical evidence regarding safety this currently limited.To examine incidence related participation and estimate rate in large cross-sectional convenience sample participants...

The 2018 CrossFit Open (CFO) was the initial stage of an annual competition that consisted five weekly workouts. Current evidence suggests a variety fitness parameters are important for progressing beyond this stage, but little is known about which most important. To examine relationships between CFO performance, experience, and physiological fitness, sixteen experienced (>2 years) athletes (30.7 ± 6.9 years, 171 12 cm, 78.0 16.2 kg) volunteered to provide information their training...
Abstract This study examined the effects of a nine-week intervention four different high-intensity training modalities [high-intensity functional (HIFT), interval (HIIT), power (HIPT), and endurance (HIET)] on resting concentration brain-derived neurotropic factor (BDNF). In addition, we evaluated BDNF responses to Graded Exercise Test (GXT) Wingate Anaerobic (WAnT) in men. Thirty-five healthy individuals with body mass index 25.55 ± 2.35 kg/m 2 voluntarily participated this were randomly...
This study examined the dose-response effects of a 1-year hybrid-type, multicomponent interval training programme (DoIT) on various musculoskeletal fitness parameters in inactive overweight and obese adults gym setting. Ninety-seven middle-aged (44.8 ± 5.2 years) individuals with overweight/obesity (31.2 5.7 kg/m2) (66% female) were randomly assigned to following groups: (i) no-intervention control (CON, n = 29), (ii) DoIT performed once weekly (DoIT-1, 24), (iii) twice (DoIT-2, 23) (iv)...
