Background: Several studies have demonstrated the positive effects of physical activity on skeletal muscle mass and strength in women with osteoporosis. However, impact Nordic walking training sarcopenia-related parameters low bone remains unknown. Therefore, purpose this study was to evaluate 12 weeks index, strength, functional mobility, performance mass. Materials methods: The participants were 45 women, aged 63–79 years, osteopenia or subjects randomly assigned either an experimental...

Background/Objectives: Optimal activation of the quadriceps femoris, particularly vastus medialis, while minimizing excessive lateralis, is crucial for treating knee injuries like ACL ruptures and patellofemoral pain syndrome. Restoring proper muscle balance may enhance rehabilitation outcomes, but effective strategies modulating activity remain unclear. High-velocity low-amplitude hip manipulation has shown potential to influence neuromuscular function, yet its impact on during extension...

Mixed Martial Arts (MMA) is a highly dynamic combat sport that requires precise motor coordination and technical execution. Video-based motion analysis, including two-dimensional (2D) three-dimensional (3D) capture systems, plays critical role in optimizing movement patterns, enhancing training efficiency, reducing injury risk. However, the comparative validity of 2D 3D systems for evaluating punching mechanics under external stressors remains unclear. This study aimed to first validate...

The study aims were to determine the distance covered by goalkeepers during matches in context of game duration and result, identify area their most frequent activity, assess goalkeepers' involvement games finished with a win, draw, or loss. investigation was based on two innovative tools: goalkeeper's activity index (GAI) an analysis 5-min periods. A video tracking system used monitor 17 from Polish National League teams 15 matches. GAI applied game. Elite 72.7%, 25.8%, 2.5%...

The aim of this study was to investigate and determine the impact asymmetries in muscle strength power between right left lower limbs on straight-line running speed female soccer players.30 right-footed players playing Ekstraliga participated study. Modulus. Number formula used avoid negative results assess only difference relative limbs, not dominance one them. A result equal or below threshold defined group G1 "with asymmetry," a above G2 greater asymmetry." It should be emphasized that...

The post-activation performance enhancement (PAPE) effect has been widely studied; however, its repeatability across training sessions during the competitive season in team sports not yet verified. Therefore, this study investigates whether PAPE effect, as measured by countermovement jump (CMJ) without arm swing, induced an maximum voluntary isometric squat a conditioning activity (ICA) three days after match, could be replicated over 4-week period throughout season. also explores magnitude...

Ten resistance-trained males (age: 27.7 ± 3.7 yr, body mass: 90.1 17.1 kg, height: 184 4 cm; experience resistance training: 5.8 2.6 relative one-repetition maximum (1RM) press: 1.23 0.22 kg/body mass) two testing conditions a randomized order. During experimental...

Abstract The aim of the study was to define relationship between maximal power lower limbs, biomechanics forward handspring vault and score received during a gymnastics competition. research involved 42 gymnasts aged 9-11 years competing in Poland’s Junior Championships. consisted three stages: first -estimating level indicators limbs tested on force plate countermovement jump; second - estimating biomechanical front vault. For both mentioned groups by vault, linear correlation analyses were...

This study aimed to determine the effect of complex training (CT) on post-activation performance enhancement (PAPE) magnitude, 5- and 30-m linear sprint, 5-0-5 change-of-direction (COD), back squat (BS) hip thrust (HT) one-repetition maximum [1RM], jumping (countermovement jump [CMJ], drop [DJ], broad [BJ]). The PAPE was elicited before after each intervention by 3 BS repetitions at 90% 1RM verified CMJ performance. Twenty-four soccer players were randomly equally assigned 6 weeks either...

(1) Background: Activation of the gluteus medius (GM) muscle while minimizing involvement tensor fascia latae (TFL) is crucial in treating many lower limb and lumbar spine injuries. Previous studies have demonstrated effectiveness joint manipulations regulating activity. The main objective this study was to evaluate effects hip manipulation (HJM) on strength activity (GM TFL) abductors asymptomatic young participants. (2) Methods: followed a double-blind randomized controlled design. Thirty...

Background: The value of volleyball players' reach is often critical to their efficient functioning in the game. It depends on jumping ability factor and player's body build. An analysis this parameter particularly difficult carry out real conditions objective research was determine height basic technical tactical actions leading Polish players during a match regard maximum values measured laboratory conditions. Material/Methods: study involved five players, representatives different...

The aim of this study was to examine whether acute whole-body vibration, a single bout drop jumps, or combination both may enhance countermovement jump (CMJ) and would affect volitional pace 3 km running performance. Twelve healthy recreationally active males completed 4 conditions in randomized order: (i) 5 sets 30 s calf raises on the platform but without vibration; (ii) vibration with rest intervals between sets; (iii) 6 interval (iv) followed by jumps sets. Before, 3-min after,...

Iron is essential for physical activity due to its role in energy production pathways and oxygen transportation via hemoglobin myoglobin. Changes iron-related biochemical parameters after exercise athletes are of substantial research interest, but molecular mechanisms such as gene expression still rarely tested sports. In this paper, we evaluated the mRNA levels genes related iron metabolism (PCBP1, PCBP2, FTL, FTH, TFRC) leukocytes 24 amateur runners at four time points: before, immediately...

This study investigated the impact of active rest intervals within a lower body complex training session on post-activation performance enhancement (PAPE) response in amateur soccer players. Twelve players took part four different experimental conditions. These sessions included 2 sets complex-paired exercises, each involving 3 repetitions either back squats or hip thrusts at 90% one-repetition maximum (1RM) as conditioning activity paired with broad jump and countermovement jump. Between...

The objective of this study was to compare (i) effects a flywheel and free-weight resistance training program; (ii) performing lateral frontal split squats as part flywheel-resistance program on jumping performance, the 5-0-5 change direction test time, one-repetition maximum (1RM) back squat in soccer players. Twenty-four male amateur players participated were randomly equally assigned one three different groups: forward split-squat group (FSQ); (LSQ); (TRAD). Athletes FSQ performed device,...

Background: Participation in extreme endurance sports is becoming an increasingly popular activity, and thus more people are getting involved it. Taking part a 100 km run associated with great physiological psychological stress, which can affect one's mood state. Thus, the goal of this study was to determine if personality, experience, motives for participation related runner's its changes as well investigate whether vitamin D3 supplementation influences 12 hours before after run.
