In-season concurrent training effects on physiological capacities relevant for elite handball performance. : An experimental study on elite male handball players (English)
Abstract [sv]

Syfte och frågeställningar: Syftet med denna studie var att undersöka de fysiologiska effekterna av kombinationsträning, innefattande styrketräning, contrast complex training (CCT) kombinerat med intervallträning i form av upprepade kortare sprintar (ca 6 s) (RSE) eller längre (30 s) högintensiva intervaller (HIIT) hos handbollsspelare i herrelit, under tävlingssäsong.

Metod: Under 12 veckor, i tävlingssäsong, genomförde 15 elithandbollsherrar, utöver sin vanliga handbollsträning antingen RSE (n=8) bestående av 10 repetitioner av shuttle sprintar (2 x 15 m) med start varje minut och med passiv vila eller HIIT (n=7) bestående av 5 reps av 30-s all-out sprintar med riktningsförändringar. Båda grupperna genomförde ocksåCCT bestående av 3 set med 3 övningar (3 x knäböj 90 % av 1RM, 6 x jump squat med 50 % av kroppsvikten, 6 x dropp jump från 30 cm Pre- och posttesterna inkluderade jump squat (JS) (RFD (Ns/kg)), 5 jump for distance test (5JT) (m), 30m sprint (5m (s), 20-30m (m/s), repeated shuttle sprint ability test (RSSA) (RSA Bäst, Sämst, Tot (s) samt beräknat trötthetindexFI (%), Sdec (%)), 1 RM knäböj (koncentrisk) (kg/kg kroppsvikt), Yo-Yo intermittent recovery test (YYIRT 1)(m) and maximal syreupptagningstest (VO2max) (l O2/min, ml·kg-0.75·min-1). Resultat: Båda grupperna ökade signifikant maxstyrkan i knäböj, RSE gruppen (8,8 %) mer än HITT (7,4 %) (p<0.01). I motsats visade HIIT gruppen större förbättringar i rate of force development (RFD) (63,3 %) än RSE (56,3 %) (p<0,05). VO2max ökade signifikant och likartat i båda grupperna (~2%). I testet för specifik uthållighet (YYIRD 1), var förbättringen i RSE gruppen 9,4 % jämfört med HIIT-gruppens 5,8 %. Både RSE (-5,7 %) och HIIT (-2 %) visade försämringar i acceleration (5 m sprint). Resultaten vid RSSA visade försämringar i alla komponenter i RSE gruppen. HITT gruppen förbättrade signifikantförmågan att motstå trötthet, Sdecvid RSA (39,1%) (p <0,09).

Slutsats: CCT verkar vara en effektiv träningsmetod för att öka maximal styrka och RFD under tävlingssäsong men att den kanske inte positivt påverkar acceleration. HIIT kan vara en mer effektiv intervallträningsmetod (än RSE) för att bibehålla eller förbättra komponenter kopplade till RSA för elithandbollsherrar, under tävlingssäsong. Kombinationsträning med handboll, CCT och HIIT verkar inte innebära något motsatsförhållande för samtidig utveckling av maxstyrka, RFD, maximal löphastighet, hopp, VO2max eller specifik uthållighet.

Abstract [en]

Aim: The aim of this study was to investigate the effects of compact complex strength training (CCT) combined with interval training, either with short shuttle sprints (~6 s) in a repeated sprint exercise (RSE) or with longer all-out sprints (30 s) also involving change of direction in a high intensity interval training (HIIT), on handball related, in-season, physical performance in male elite players.

MethodFor 12 weeks, in-season, 15 elite handball players performed, in addition to their normal handball training, either RSE (n = 8) sessions consisting of 10 repetitions of shuttle sprints (2x15m), start every 60 s and with passive recovery or HIIT (n = 7) consisting of 5 repetitions of 30-s all-out sprints with change of direction. Both groups also did CCT consisting of 3 sets of 3 exercises (3 x squat 90% of 1RM, 6 x jump squat 50% of the bodyweight and 6 x drop jump from 30 cm).. Pre- and posttests included jump squat (JS) (RFD (Ns/kg)), jump for distance test (5JT) (m), 30m sprint (5m (s), 20-30m (m/s)), repeated shuttle sprint ability test (RSSA) (RSA Best, Worst, Tot (s), FI (%), Sdec (%)),  1 RM squat (concentric) (kg/kg bodyweight), Yo-Yo intermittent recovery test (YYIRT 1) (m) and maximum oxygen test (VO2max) (l O2/min, ml·kg-0.75·min-1).

Results: Both groups significantly (p<0.01) improved their maximum strength in squat, the RSE-group (8.8 %) more so than HIIT (7.4 %). In contrast the HIIT-group showed greater improvements in rate of force development (RFD) (63.5%) than RSE (56.3%) (p< 0.05). VO2max was significantly increased with similar gains in both groups (~2%). In the test for specific endurance, YYIRD1, the RSE-group’s improvement was 9.4 % compared with HIIT’s 5.8%. Both RSE (-5.7 %) and HIIT (-2%) groups showed decrements in acceleration (5 m sprint time). The results in the RSSA show decrements in all components in the RSE-group. HIIT’s significantly improved the ability to resist fatigue Sdec (29.1%) (p <0.09).

Conclusion: CCT appear to be an effective in-season training method for gaining strength and RFD, but may not positively affect acceleration. HIIT may be a more effective interval training method (than RSE) for maintaining or improving components linking to RSA for elite male handball players during competition (match) season. Concurrent training of CCT and HIIT shows no interference in the development of strength, running speed, jump, RFD, VO2max or specific handball endurance.
