The aim of the present study was to investigate the psychological profile of the 2023 Hungarian National Distance Running Team in terms of personality traits, motivational styles, and competitive anxiety and to explore specific psychosocial factors that characterize the athletes’ mental preparation. The 16 international-level competitors were assessed using validated questionnaires in Hungarian (Big Five Inventory, the revised Sport Motivation Scale, and Competitive State Anxiety Inventory-2), and university students competing at professional and semiprofessional levels served as the control group. Results indicated that elite distance runners were primarily intrinsically motivated. Their psychological profile appeared similar to profiles found among athletes in the control group. Significant differences were found in traits, such as openness, conscientiousness, and motivation. Neuroticism was positively associated with athletes’ cognitive and somatic anxiety, with self-confidence providing a protective role. Working with a sports psychologist appeared to have no significant measurable effect on athletes precompetition anxiety. Specific personality traits and motivational structures are essential for elite sporting performance. Further research is needed to better understand and determine the specific components of mental preparation.

The Effects of Running Foot Strike Manipulation on Pelvic Floor Muscle Activity in Healthy Nulliparous Females
Michael Steimling, Melinda Steimling, Philip Malloy, and Kathleen Madara
Vertical loading rate (VLR) and pelvic floor muscle activity (PFA) increase with running velocity, which may indicate a relationship between VLR and PFA. Foot strike pattern has been shown to influence VLR while running, but little is known about its influence on PFA. Twenty healthy women ran on a treadmill for 2 conditions: with a rearfoot strike and with a forefoot strike. PFA was measured with electromyography. Running kinematics associated with VLR were collected using inertial measurement units and tibial accelerometers. Change scores between conditions were calculated for average PFA and running kinematics: peak vertical tibial acceleration, vertical excursion of the center of mass (VO), and cadence. Paired t tests assessed differences between running conditions for all variables. Pearson correlations assessed the relationships between changes in PFA and running kinematics. PFA was significantly higher during the forefoot compared with the rearfoot strike condition. Change in vertical tibial acceleration was positively correlated with change in PFA during the right stance. Change in cadence was negatively correlated, and change in vertical excursion of the center of mass was positively correlated with change in PFA during left stance. The average PFA increased during the forefoot strike pattern condition. Changes in PFA were correlated with changes in running kinematics associated with VLR.
APAQ at Forty: Publication Trends
Jeffrey J. Martin
The purpose of the present study was to analyze Adapted Physical Activity Quarterly (APAQ) publications over the journal’s fourth decade (2014–2023) and compare them with previous documentary analyses of the first 3 decades. Consistent with prior documentary analyses, publications were coded and analyzed based on the use of theory, research participants, topic, whether the study was an intervention, first-author country affiliation, and research method. The total number of published research papers increased substantially (n = 61) from the third to the fourth decade. Similar to prior documentary analyses, most of the research was quantitative (n = 140; 57.5%), followed by qualitative research (n = 96; 39.5%). There were far more qualitative-research publications in the fourth decade compared with the third decade (n = 34). This may reflect the continued acceptance and growth of qualitative research compared with 10–20 years ago. It may also reflect the value of rich in-depth exploratory research using small samples. Additional trends included more review papers and meta-analyses, possibly reflecting the increased knowledge base in particular areas requiring synthesis. The diversity of topics also increased, with papers on dignity, classification, coaching, and the Paralympics playing more prominent roles. The number of international publications also grew substantially. In brief, the current paper outlines both similarities and differences in APAQ’s published research over the 4 decades of its existence.

Understanding the changes in running mechanics caused by fatigue is essential to assess its impact on athletic performance. Changes in running biomechanics after constant speed conditions are well documented, but the adaptive responses after a maximal incremental test are unknown. We compared the spatiotemporal, joint kinematics, elastic mechanism, and external work parameters before and after a maximal incremental treadmill test. Eighteen recreational runners performed 2-minute runs at 8 km·h−1 before and after a maximal incremental test on a treadmill. Kinematics, elastic parameters, and external work were determined using the OpenCap and OpenSim software. We did not find differences in spatiotemporal parameters and elastic parameters (mechanical work, ankle, and knee motion range) between premaximal and postmaximal test conditions. After the maximal test, the runners flexed their hips more at contact time (19.4°–20.6°, P = .013) and presented a larger range of pelvis rotation at the frontal plane (10.3°–11.4°, P = .002). The fatigue applied in the test directly affects pelvic movements; however, it does not change the lower limb motion or the spatiotemporal and mechanical work parameters in recreational runners. A larger frontal plane motion of the pelvis deserves attention due to biomechanical risk factors associated with injuries.
Directional-Specific Modulation of Postural Control and Stepping Kinematics in Multidirectional Gait Initiation
Kuanting Chen and Adam C. King
Daily living activities present a diverse array of task and environmental constraints, highlighting the critical role of adapting gait initiation (GI) for an individual’s quality of life. This study investigated the effects of GI directions, obstacle negotiation, and leg dominance on anticipatory postural adjustments and stepping kinematics. Fourteen active, young, healthy individuals participated in GI across 4 directions—forward, medial 45°, lateral 45°, and lateral 90°—with variations in obstacle presence and leg dominance. Results revealed a consistent decreasing trend in maximum center of pressure displacement, anticipatory postural adjustment duration, step distance, and swing leg velocity with lateral shifts in GI directions, yet the step duration and swing leg heel trajectory were not affected by GI directions except in lateral 90° GI. Center of pressure displacements were intricately scaled to directional propulsive forces generation, and the stepping kinematics were influenced by the directional modifications in movements. With obstacles, modifications in anticipatory postural adjustment metrics and stepping kinematics reflected the obstacle clearance movements. The dominant leg GI exhibited longer step durations and greater movement variability in medial 45° GI. The current investigation of GI factors expands our existing understanding of GI dynamics and offers valuable insights applicable to fall prevention and gait rehabilitation strategies.
The Effects of Different Myofascial Release Techniques on Pain, Range of Motion, and Muscle Strength in Athletes With Iliotibial Band Tightness: A Randomized Controlled Study
Bayram Sonmez Unuvar, Ertugrul Demirdel, and Hasan Gercek
Context: We designed this study to investigate the effects of 2 myofascial release techniques, Instrument-Assisted Soft Tissue Mobilization (IASTM) and Foam Roller (FR), on pain, joint range of motion, and muscle strength in athletes suffering from iliotibial band (ITB) tightness. Design: A total of 39 male soccer players were enrolled in this randomized controlled trial, aged between 18 and 23 years who were divided into 3 groups: Only Exercise, IASTM, and FR. Methods: All participants performed daily strengthening and stretching exercises, while 1 group added IASTM, and the other added FR to the exercise program. We evaluated ITB tightness with the Ober test and an inclinometer, pressure pain threshold, using an algometer, and we evaluated muscle strength with the Cybex Norm Isokinetic device. Results: We found that all 3 groups exhibited an increase in the Ober inclination angle after the interventions (P = .001), but the increase was greater for participants in the IASTM and FR groups, compared with exercise alone. Additionally, both the IASTM and FR groups displayed an increased pressure pain threshold (P = .001), whereas there was no change in the control group. Moreover, while all 3 groups experienced an increase in hip muscle strength (P = .001), the IASTM and FR groups exhibited a greater increase compared with exercise alone (P = .001). Conclusions: Based on these findings, exercise improves pain, range of motion, and muscle strength in athletes with ITB tightness, and IASTM, and FR techniques enhanced exercise effects but did not differ from one another. While our study demonstrated that both IASTM and FR techniques significantly enhance the benefits of exercise for athletes with ITB tightness, further research could delve into the long-term effects of these interventions.
Vision Is Not Required to Elicit Balance Improvements From Beam Walking Practice
Natalie Richer, Steven M. Peterson, and Daniel P. Ferris
Background: Beam walking is a highly studied assessment of walking balance. Recent research has demonstrated that brief intermittent visual rotations and occlusions can increase the efficacy of beam walking practice on subsequent beam walking without visual perturbations. We sought to examine the influence of full vision removal during practice walking on a treadmill-mounted balance beam. Although visual disruptions improved performance of this task, we hypothesized that removing visual feedback completely would lead to less balance improvements than with normal vision due to the specificity of practice. Methods: Twenty healthy young adults trained to walk at a fixed speed on a treadmill-mounted balance beam for 30 min, either with, or without, normal vision. We compared their balance pre-, during, and posttraining by calculating their step-offs per minute and the percentage change in step-offs per minute. Results: Balance improved in both groups after training, with no significant difference in percentage change in step-offs between the normal vision and the no vision participants. On average, the no vision participants had twice as many step-offs per minute as the normal vision group during training. Conclusion: Although previous experiments show that intermittent visual perturbations led to large enhancements of the effectiveness of beam walking training, completely removing visual feedback did not alter training effectiveness compared with normal vision training. It is likely a result of sensory reweighting in the absence of vision, where a greater weight was placed on proprioceptive, cutaneous, and vestibular inputs.
Effect of External Work Magnitude on Mechanical Efficiency of Sledge Jumping
Keitaro Seki and Heikki Kyröläinen
The mechanical efficiency of human locomotion has been studied extensively. The mechanical efficiency of the whole body occasionally exceeds muscle efficiency during bouncing type gaits. It is thought to occur due to elasticity and stiffness of the tendinomuscular system and neuromuscular functions, especially stretch reflexes. In addition, the lower limb joint kinetics affect mechanical efficiency. We investigated the impact of varying external work on mechanical efficiency and lower limb kinetics during repeated sledge jumping. Fifteen male runners performed sledge jumping for 4 minutes at 3 different sledge inclinations. Lower limb kinematics, ground reaction forces, and expired gases were analyzed. Mechanical efficiency did not differ according to sledge inclination. Mechanical efficiency correlated positively with the positive mechanical work of the knee and hip joints and the negative contribution of the hip joints. Conversely, it correlated negatively with both the positive and negative contributions of the ankle joint. This may be attributable to the greater workload in this study versus previous studies. To achieve greater external work, producing more mechanical energy at the proximal joint and transferring it to the distal joint could be an effective strategy for improving mechanical efficiency because of the greater force-generating capability of distal joint muscles.
