Uncovering intensity trajectory patterns and their association with blood pressure adaptation following school-based high-intensity interval exercise in adolescents
Introduction This study examined intensity patterns during school-based high-intensity interventions and their association with blood pressure (BP) adaptation in adolescents. Methods A total of 145 students aged 16 (69 boys) participated in either traditional HIIT or a plyometric variant (HIPT) over eight weeks (16 sessions). Exercise intensity was calculated using the heart rate reserve method. Outcomes of interest were systolic and diastolic bl…
Which Age Matters? Comparing Chronological and Biological Age in Adolescent Adaptation to School-Based Physical Activity Interventions (Wrocław Peer-Heart Study)
Background/Objectives: Relative age differences within the same school year may influence adolescents' physiological adaptations to physical activity programs. While biological maturity (maturity offset, MO) is often considered a more relevant indicator than chronological age (CA), empirical evidence from school-based interventions remains limited. This study aimed to compare the predictive value of CA and MO in explaining health-related adaptati…
Socioeconomic inequalities in health-related fitness gradient shifts between 2001 and 2022 in young Polish adults
Background This study aimed to assess the importance of socioeconomic status (SES) on health-related fitness (H-RF) measurements in young adults and determine the impact of SES over 20 years of substantial social and economic changes in Poland. Material and methods The study compared H-RF differences between 2001 (P 1 ) and 2022 (P 2 ) in 252 volunteers aged 18 to 28 years who were grouped into quartiles based on SES and gender. The variables mea…
The Relative Importance of Age at Peak Height Velocity and Fat Mass Index in High-Intensity Interval Training Effect on Cardiorespiratory Fitness in Adolescents
Background: This study aimed to evaluate the role of biological age in the relationship between preintervention fat mass and cardiorespiratory fitness effects (CRF) after High-Intensity Interval Training (HIIT) intervention in adolescents. Methods: A total of 141 boys and girls (16 years) were examined as control (CG) and experimental (EG) groups that conducted a 10-week HIIT implemented in physical education. Measurements: body height, body weig…
Acute Effect of Short Intensive Self-Myofascial Release on Jump Performance in Amateur Athletes
Searching for effective methods to maximize physical performance that can be utilized during warm-ups is challenging in modern sports. This study aimed to investigate the effect of a short and intensive self-myofascial release (SI-SMR) on jumps in amateur, collegiate athletes. The study sample consists of 30 subjects with an average age of 21.8 years. The tests conducted included a squat jump (SJ), countermovement jump (CMJ), and drop jump (DJ). …
The Mediation Role of Fatness in Associations between Cardiorespiratory Fitness and Blood Pressure after High-Intensity Interval Training in Adolescents
Fatness mediated associations between CRF and SBP in boys. Therefore, both CRF and fatness are necessary to maintain positive results of the BP revealed in normal SBP ranges after HIIT
Risk of Single and Multiple Injuries Due to Static Balance and Movement Quality in Physically Active Women
Background: Static balance is a reliable indicator of the musculoskeletal and nervous systems, which is a basis for movement stabilization development. The disorders in this area may increase injury risk (IR). This study investigated the musculoskeletal injury risk due to static balance and movement quality regarding single and multiple injury occurrences in physically active women. Methods: The study sample was 88 women aged 21.48 ± 1.56. The in…
Changes in Anthropometric Measurements and Physical Fitness of Polish Students in 20-Year Period
Despite young adults claiming to have similar physical activity levels to those observed in the past, they demonstrate poorer physical performance and higher body fat levels. The observed changes can be considered negative
Prognostic Potential of the Body Composition Indices in Predicting Positive Changes in Resting Blood Pressure after High-Intensity Interval Training in Adolescents
This study aimed to investigate the prognostic potential of body composition indices in predicting the improvement in resting blood pressure after 10 weeks of high-intensity interval training (HIIT) implemented in physical education lessons. The participants were 141 adolescents aged 16 years. Independent variables were body mass index (BMI), fat mass index (FMI), muscle mass index (SMI), and mass to fat ratio (MFR); dependent variables were syst…
The Impact of Physical Performance on Functional Movement Screen Scores and Asymmetries in Female University Physical Education Students
Association between physical performance and movement quality remains ambiguous. However, both affect injury risk. Furthermore, existing research rarely regards women. Therefore, this study aimed to assess the impact of physical performance components on FMS scores and asymmetries among young women-University Physical Education Students. The study sample was 101 women, 21.72 ± 1.57 years, body mass index 21.52 ± 2.49 [kg/m 2 ]. The FMS test was c…
Effects of Combination Movement Patterns Quality and Physical Performance on Injuries in Young Athletes
Identifying the factors associated with the injuries is crucial to prevention, enabling apply effective methods to reduce injuries frequency. This is especially important for young athletes for whom an injury may impair development or prematurely end a sports career. Therefore, the objective of this study is to examine if the movement patterns quality and physical performance simultaneously affected injury occurrence in young athletes. The partic…
