Opis: The application of resistance over the shoulder or hips during resisted sprints could influence performance outcomes but has not been thoroughly investigated. This study examined the within-session reliability of sprint performance measures and compared the outcomes of 1080 Sprint device between belt (hips) and harness (shoulders) attachment. Twelve student-athletes completed three 20 m sprints with resistance equivalent to 25% of body mass (14.0 to 24.7 kg). Sprint split times (5 m, 10 m, 15 m, 20 m), peak velocity, and distance at peak velocity were recorded with 1080 Sprint. Within-session reliability was assessed using intraclass correlation coefficients (ICC3.1) and coefficients of variation (CV), while differences in performance were analysed using paired t-tests and effect sizes (ES). Reliability was excellent for all variables (ICC3.1≥ 0.93; CV ≤ 3.08 %) except distance at peak velocity, which showed poor reliability (ICC3.1≥ 0.32; CV ≥ 17.2 %). Sprint times and peak velocity were faster with the belt attachment (ES ≥ 0.93), while peak velocity was reached earlier with the harness attachment (ES = 0.65). Both attachment points provided reliable measurements, but the belt consistently resulted in faster 20 m sprint performance. Coaches and practitioners should consider these differences when assessing resisted sprint performance or prescribing training to ensure consistent and individualized loading strategies

Opis: Izhodišča: McGillov model zdravstvene nege je celostni, sodelovalni pristop, ki poudarja aktivno vlogo pacienta, vključevanje bližnjih in krepitev psihosocialne podpore. Kljub uveljavljenosti v mednarodnem prostoru njegova uporaba v slovenski klinični praksi še ni bila raziskana. Namen raziskave je bil ovrednotiti, v kolikšni meri medicinske sestre na področju onkološke zdravstvene nege uporabljajo pristope McGillovega modela, ki vključujejo sodelovanje pacientov, vključevanje družinskih članov in krepitev psihosocialne podpore. Metode: V kvantitativni presečni raziskavi je bilo k sodelovanju povabljenih približno 400 medicinskih sester, zaposlenih na področju onkološke zdravstvene nege. Vprašalnik je pričelo izpolnjevati 166 oseb, od tega ga je popolnoma izpolnilo 126 (odzivnost 31,5 % glede na populacijo medicinskih sester zaposlenih na področju onkološke zdravstvene nege). Večina anketirancev je bila ženskega spola (77,8 %). Povprečna starost anketirancev je bila 37,71 leta (s = 8,07) s povprečno delovno dobo na področju onkološke zdravstvene nege 9,66 leta (s = 7,93). Analiza je temeljila le na popolnoma rešenih vprašalnikih. Podatke smo zbrali z novo razvito lestvico, ki temelji na McGillovem sodelovalnem modelu. Anketiranci so trditve ocenjevali na petstopenjski lestvici, ki meri pogostost izvajanja pristopov ali stopnjo strinjanja z izjavo. Izvedli smo eksploratorno in konfirmatorno faktorsko analizo, Wilcoxonove in Mann–Whitneyjeve teste ter Spearmanovo korelacijo. Rezultati: Faktorska analiza je potrdila tri konstrukte, ki pojasnjujejo 65,3 % skupne variance (KMO = 0,896; Bartlett p < 0,001). Empirične mediane vseh treh konstruktov so bile statistično značilno višje od teoretičnih (p < 0,001), kar pomeni, da so anketiranci poročali o uporabi pristopov McGillovega modela. Anketiranci z dostopom do pisnih protokolov ali organizacijsko podporo so dosegali višje rezultate (p < 0,001). Ugotovljene so bile zmerne do visoke pozitivne korelacije med uporabo pristopov in zaznavo izboljšanja oskrbe ter psihosocialnega stanja onkoloških pacientov (p < 0,001). Zaključek: Rezultati potrjujejo, da se v onkološki zdravstveni negi pogosto uporabljajo pristopi McGillovega modela, kar pozitivno sovpada z zaznanim izboljšanjem kakovosti oskrbe. Model ima potencial za širšo in bolj formalizirano implementacijo v klinično prakso.

Opis: Background and purposeThe development of athletic performance requires a detailed assessment of the relationship between maximal strength and the ability to express it explosively. Traditional tests one-repetition maximum do not differentiate the rate of force development, which led to the introduction of the Dynamic Strength Index, defined as the ratio between force in the countermovement jump and the isometric mid-thigh pull . The aim of this paper was to present the theoretical background, methodological approaches, and practical applications of Dynamic Strength Index in order to optimize training and prevent injuries.Materials and methodsDynamic Strength Index is calculated by measuring peak force in countermovement jump and isometric mid-thigh pull tests using a force plate. Standardization of protocols (body position, contraction duration, software processing) is essential for validity. Test–retest reliability is high (Intraclass Correlation Coefficient >0.90). Normative values vary by sport and playing position: for example, sprinters and jumpers often record Dynamic Strength Index values >0.80, while weightlifters usually show lower values (<0.60).ResultsFindings indicate that DSI is an effective tool for training individualization. Values below 0.60 suggest the need for plyometric and ballistic training, while values above 0.80 point to a focus on maximal strength development. The optimal range (0.60–0.80) reflects a balanced profile. DSI is also useful for longitudinal monitoring of adaptations, adjusting training loads, and identifying injury risks. However, variability in testing protocols, anthropometric differences, and software processing may limit its applicability and comparability across studies.ConclusionDynamic Strength Index is a valuable biomechanical indicator linking maximal and explosive strength, allowing precise programming of training and performance monitoring. Its use has already been established in elite sports, but full validation requires measurement standardization and the development of sport-specific normative databases. Future directions include phase-specific force analysis within contraction cycles, expanding testing protocols, and integrating digital platforms for automated analysis.
