Abstract [en]

The study aimed to identify a small set of fitness tests that could effectively predict performance in simulated firefighting tasks. Thirty-six (25 male and 11 female) firefighters participated in the study. Strength was evaluated with grip strength, barbell bench rows, and elevated trap bar deadlifts. Work capacity was assessed using a 3-minute pyramid test, executed with and without firefighting equipment. Firefighting performance was evaluated using a simulated work task course comprising stair climbing, hose pull, victim rescue, and equipment carry. We used backward linear regressions to derive models incorporating fitness test results, demographic variables, and oxygen uptake measures as predictors. Statistical significance was set to p < 0.05. The pyramid test without equipment accounted for 59% of the variance in task performance. When body mass and height were included, the model's predictive power increased to 71%. A final model, integrating the pyramid test, body mass, and absolute maximal oxygen uptake capacity (V̇o2max), explained 81% of performance variation. Our findings indicate that V̇o2max is the key factor in firefighter task performance, explaining 69% of the variance. The pyramid test, which estimates V̇o2max and predicted 59% of performance, is simple, time efficient, and can be conducted at stations to assess physical ability and work capacity. Incorporating the pyramid test into regular assessments can help firefighters focus on improving their work capacity, which is essential for achieving better performance.

Abstract [en]

This study aimed to investigate the effect of intrasession exercise order of maximal effort flywheel resistance training (RT; 436 repetitions [rep]) and high-intensity interval training (HIIT, 2–438 rep of 20 second at 130% of Watt atV̇O2max [wV̇O2max]), on the development of maximal strength and power in elite team-sport athletes. A 7-week training intervention involving 2 training sessions per week of either HIIT followed by RT (HIIT + RT, n 5 8), RT followed by HIIT (RT + HIIT, n 5 8), or RTalone (RT, n 5 7) was conducted in 23 elite male bandy players (24.7 6 4.3 years). Power and work were continuously measured during the flywheel RT. Isometric squat strength (ISq), countermovement jump, squat jump, and V̇O2max were measured before and after the training period. Power output during training differed between the groups (p 5 0.013, h2p5 0.365) with RT producing more power than HIIT + RT (p 5 0.005). ISq improved following RT + HIIT (;80%, d 5 2.10, p 5 0.001) and following HIIT + RT(;40%, d 5 1.64, p 5 0.005), and RT alone (;70%, d 5 1.67, p 5 0.004). V̇O2max increased following RT + HIIT and HIIT + RT(;10%, d51.98, p50.001 resp. d52.08, p50.001). HIIT before RT reduced power output during RT in elite team-sport athletes but did not lead to blunted development of maximal strength or power after a 7-week training period. During longer training periods(.7-weeks), it may be advantageous to schedule RT before HIIT because the negative effect of HIIT + RT on training quality increased during the final weeks of training. In addition, the largest training effect on maximal strength was observed following RT +HIIT.

Abstract [en]

Physical characteristics of elite male bandy players have not been studied for the last 30 years. Therefore, the purpose of this study was to evaluate the physical characteristics of elite male bandy players with respect to playing positions. A cross-sectional study was performed that included 25 male bandy players from one of the highest-ranked bandy leagues in the world. Body weight, length, isometric mid-thigh pull, countermovement jump, squat jump, unilateral long jump, bilateral long jump, 15- and 30-m sprint, 15-m flying sprint, and VO2max were tested. Players were divided into forwards, midfielders, and defenders. Forwards had significantly (p = 0.012) higher relative VO2max than defenders (59.8 ± 4.3 compared to 53.0 ± 5.6 mL/kg/min). No significant differences for any of the other measurements were observed between positions. This is the first study to present the physical characteristics between playing positions in off- and on-ice tests for male bandy players competing at the highest level. Today's bandy players are heavier and have lower relative VO2max compared with players in the early 1990s. However, their work capacities have increased since their absolute VO2max is higher. These results provide benchmark values that can serve as a foundation for strength and conditioning professionals when designing future training programs.

Abstract [sv]

Fosbury flop i höjdhopp, V-stilen i backhoppning, skate i längdskidåkning och rotationstekniken i kulstötning. Alla är exempel på hur nya idrottstekniker utvecklats. Men lika viktigt som att nya idrottstekniker utvecklas är att de befintliga teknikerna förfinas och anpassas utifrån den aktives förutsättningar. Häftet Bättre idrottsteknik– genom analys och träning beskriver hur man i generella termer analyserar och tränar den idrottsspecifika tekniken och vänder sig till både aktiva och tränare för såväl barn och ungdomar som elit och elitmotionärer. Häftet inleds med grundläggande kunskap om samspelet mellan muskler och nervsystemet, rörelser och biomekaniska principer. Bärande kapitel är sedan hur man analyserar teknik samt hur man på bästa sätt kan strukturera och genomföra teknikträning för att såväl förebygga skador som nå bättre prestationer.

Abstract [sv]

Bakgrund och syfte. Syftet med hälsoprojektet under 8-12 veckor för äldre är att ge ledarledd fysisk aktivitet 2 gånger/vecka samt att utvärdera upplevd hälsa, förändring av livsstilssvanor samt fysisk kapacitet. Hälsoprojektet är ett fortlöpande samarbete mellan Solna stad och Gymnastik- och idrottshögskolan (GIH) och utförs under vårterminerna sedan ett flertal år.

Metod. Individerna anmäler sitt deltagande själva. Det kostnadsfria hälsoprojektet utförs inom undervisningen i Folkhälsa i regi av GIH-studenter under handledning av verksamhetschefen i Solna stad och lärare/läkare på GIH. Den ledarledda fysiska aktiviteten utgörs primärt av stavgång, motionsgymnastik, vattengymnastik samt styrketräning. Initialt och i slutet av perioden besvarar deltagarna en hälsoenkät angående upplevd hälsa och livsstilsvanor om fysisk aktivitet, kost, sömn, rökning och alkohol samt utför några olika fysiologiska tester i samband med ett hälsosamtal.

Resultat. Exempel på sammanställda resultat ges här för de 117 äldre som fullföljde hela projektet under en vårtermin (för kvinnorna var antalet samt medelvärden för ålder och BMI 99, 74år och 26 respektive för männen 18, 73år och 25). Efter avslutat projekt sågs för gruppen som helhet generellt en signifikant förbättrad upplevd fysisk och mental hälsa, kondition och styrka i buk-, ben- och armmuskulatur. För kvinnorna observerades även en ökad balansförmåga och uthållighet i ryggmusklerna. Enkätfrågorna angående fysiska aktivitetsvanor och stillasittande visade på, efter avslutat projekt, en förändring till en mer aktiv livsstil.

Slutsats/Diskussion. Således kan utvärderade 8-12 veckors hälsoprojekt med ledarledd fysisk aktivitet för äldre bidra till förbättrad upplevd hälsa, ökade fysiska aktivitetsvanor, minskat stillasittande och bättre fysiska kapaciteter såsom kondition, styrka och balans som är positivt korrelerade till ökad livslängd och minskad förekomst av en mängd olika folksjukdomar och skador. Fler projekt och studier behövs framöver med ytterligare uppföljningar, jämförelser och för att vidareutveckla olika fysiologiska tester och andra hälsoparametrar som kan ha positiva samband med ökad hälsa.
