I september 2014 bytte Leeds Metropolitan University, trots studentprotester, namn till Leeds Beckett University; universitetets första colleges låg i Beckett Park, vilken i sin tur fått namn efter bankiren och konservative parlamentsledamoten Ernest Beckett, 2nd Baron Grimthorpe (1856–1917), vars alma mater faktiskt var Trinity College, Cambridge. Leeds-studenternas motstånd hade sin grund i att namnändringen beräknades kosta en kvarts miljon pund, alltmedan inte minst universitetets idrottsanläggningar tillåtits förfalla. Vi vet inte hur universitetets personal ställde sig till namnförändringen, och särskilt nyfikna är vi ju på vad professorn i Leisure Studies (fritidsforskning, fritidsvetenskap) vid Leeds Beckett University, Karl Spracklen, tyckte om förändringen. Detta är dock blott "idle curiosity"; Spracklen är aktuell av ett helt annat, och viktigare, skäl, nämligen för sin bok Leisure, Sports & Society (Palgrave Macmillan). Spracklen, som är sociolog och vars forskningsintresse också inkluderar "metal music" (som sekreterare för International Society for Metal Music Studies och redaktör för Metal Music Studies) och "whiskey tourism" (som drivande i British Sociological Associations Alcohol Study Group) är en centralfigur inom det brittiska fritidsforskningsetablissemanget – han har bland annat varit ordförande i viktiga LSA, Leisure Studies Association från 2009 till 2013. Han har därtill en lång rad publikationer bakom sig, böcker, antologibidrag och vetenskapliga artiklar inom idrotts- och fritidsforskning i vid mening. Den nya boken ges här en grundlig recension av Erik Backman, som ju vet ett och annat om fritidsforskning, Spracklen bottnar teoretiskt i Habermas, i sig ovanligt bland brittiska forskare, men också i Marx, Weber och Bourdieu, bland andra, i sin utforskning av sambandet mellan fritid, fysisk aktivitet och sport ur ett tvärvetenskapligt perspektiv som innefattar idrottsvetenskap, sociologi, cultural studies, historia, filosofi och psykologi. Och vår recensent är imponerad över bredden, djupet och ambitionsnivån – även om det kan bli lite tjatigt från och till.

The purpose was to determine the magnitude of aerobic and anaerobic performance factors among elite male football players in different team positions. Thirty-nine players from the highest Swedish division classified as defenders (n=18), midfield players (n=12) or attackers (n=9) participated. Their mean (± sd) age, height and body mass (bm) were 24.4 (±4.7) years, 1.80 (±5.9)m and 79 (±7.6)kg, respectively. Running economy (RE) and anaerobic threshold (AT) was determined at 10, 12, 14, and 16km/h followed by tests of maximal oxygen uptake (VO2max). Maximal strength (1RM) and average power output (AP) was performed in squat lifting. Squat jump (SJ), counter-movement jump with free arm swing (CMJa), 45m maximal sprint and the Wingate test was performed. Average VO2max for the whole population (WP) was 57.0mL O2•kg-1min-1 . The average AT occurred at about 84% of VO2max. 1RM per kg bm0.67 was 11.9±1.3kg. Average squat power in the whole population at 40% 1RM was 70±9.5W per kg bm0.67 . SJ and CMJa were 38.6±3.8cm and 48.9±4.4cm, respectively. The average sprint time (45m) was 5.78± 0.16s. The AP in the Wingate test was 10.6±0.9W•kg-1 . The average maximal oxygen uptake among players in the highest Swedish division was lower compared to international elite players but the Swedish players were better off concerning the anaerobic threshold and in the anaerobic tests. No significant differences were revealed between defenders, midfielders or attackers concerning the tested parameters presented above.

The purpose was to determine running economy and lactate threshold among a selection of male elite football players with high and low aerobic power. Forty male elite football players from the highest Swedish division (“Allsvenskan”) participated in the study. In a test of running economy (RE) and blood lactate accumulation the participants ran four minutes each at 10, 12, 14, and 16 km•h-1 at horizontal level with one minute rest in between each four minutes interval. After the last sub-maximal speed level the participants got two minutes of rest before test of maximal oxygen uptake (VO2max). Players that had a maximal oxygen uptake lower than the average for the total population of 57.0 mL O2•kg-1•minute-1 were assigned to the low aerobic power group (LAP) (n=17). The players that had a VO2max equal to or higher than 57.0 mL O2•kg-1•minute-1 were selected for the high aerobic power group (HAP) (n=23). The VO2max was significantly different between the HAP and LAP group. The average RE, measured as oxygen uptake at 12, 14 and 16km•h-1 was significantly lower but the blood lactate concentration was significantly higher at 14 and 16 km•h-1 for theLAP group compared with the HAP group.
