  ABSTRACT The purpose of this study was to compare the effects of a 1‐week block of moderate‐intensity interval training (MIT) and high‐intensity interval training (HIT) in well‐trained cyclists. Cyclists (♀ = 1; ♂ = 21; maximal oxygen uptake (V̇O 2max ) = 69.5 (6.0) mL·min −1 ·kg −1 ) performed both a MIT block involving 6 sessions over 7 days (5–7 × 10–14‐min work intervals, rate of perceived exertion (RPE): 14.5 (0.3)) and a HIT block involving 5 sessions over 6 days (5 × 8.75‐min with multiple short intervals, RPE: 17.1 (0.4)). Post‐testing was performed after 6 days of active recovery, and blocks were separated by 2 months. Testing included 15‐min maximal cycling power (PO 15min ), 10 s maximal sprint power (PO 10sec ), and power output at a blood lactate concentration of 4 mmol·L −1 (PO 4mmol ). Both the MIT and HIT block improved PO 15min (4.9 (8.7)% and 2.8 (5.3)%, respectively), with no difference between blocks ( p  = 0.44). MIT displayed greater improvement than HIT in PO 4mmol (4.5 (4.5)% vs. 2.1 (2.7)%, respectively, p  = 0.03, moderate effect size (ES)), while HIT had a moderate ES compared to MIT for improvement in PO 10sec (1.5 (3.7)% vs. −1.5 (7.3)%, respectively), that was not significant ( p  = 0.08). No differences were observed between blocks in changes in V̇O 2max ( p  = 0.43) or measures of gross efficiency ( p range  = 0.43–0.79). However, MIT induced a larger increase in % of V̇O 2max at PO 4mmol compared to HIT (1.2 (3.4)%‐points vs. −0.9 (2.5)%‐points, respectively, p  = 0.02, moderate ES). In conclusion, both a MIT block (lower work interval intensity but longer work duration) and a HIT block (higher work interval intensity but shorter work duration) can improve endurance performance determinants and PO 15min with some work intensity‐specific adaptations.

The higher oxygen consumption during multiple short intervals is sex-independent and not influenced by skeletal muscle characteristics in well-trained cyclists. European Journal of Sport Science (EJSS). ISSN 1746-1391. doi: 10.1002/ejsc.12214. Fulltekst i vitenarkiv Vis sammendrag

  It has been suggested that time spent at a high fraction of maximal oxygen consumption (%mathematical equationO2max) plays a decisive role for adaptations to interval training. However, previous studies examining how interval sessions should be designed to achieve a high %mathematical equationO2max have exclusively been performed in males. The present study compared the %mathematical equationO2max attained during three different 6 × 8 min interval protocols, in female (n = 11; mathematical equationO2max, 62.5 (6.4) mL · min−1·kg−1) and male (n = 8; mathematical equationO2max, 81.0 (5.2) mL · min−1·kg−1) cyclists. Mean power output during work intervals were identical across the three interval protocols, corresponding to the cyclist's 40 min maximal effort (PO40min): (1) 30 s intervals at 118% of PO40min interspersed with 15 s active recovery at 60% (30/15), (2) constant pace at 100% of PO40min (CON), and (3) altering between 60 s intervals at 110% and 60 s at 90% of PO40min (60/60). Additionally, the study explored whether the m. vastus lateralis characteristics of the cyclists (fiber type proportion, capillarization, and citrate synthase activity) were associated with the %mathematical equationO2max attained during the interval sessions. Overall, mean %mathematical equationO2max and time ≥90% of mathematical equationO2max were higher during 30/15 compared to CON (86.7 (10.1)% and 1123 (787) s versus 85.0 (10.4)% and 879 (779) s, respectively; both p ≤ 0.01) and 60/60 (85.6 (10.0)% and 917 (745) s, respectively; both p ≤ 0.05), while no difference was observed between 60/60 and CON (both p ≥ 0.36). During interval sessions, %mathematical equationO2max and time ≥90% of mathematical equationO2max did not differ between sexes. Skeletal muscle characteristics were not related to %mathematical equationO2max during interval sessions. In conclusion, well-trained cyclists demonstrate highest %mathematical equationO2max during 30/15, irrespective of sex and skeletal muscle characteristics.

The higher the fraction of maximal oxygen uptake is during interval training, the greater is the cycling performance gain. European Journal of Sport Science (EJSS).

  It has been suggested that time at a high fraction (%) of maximal oxygen uptake (VO2max) plays a decisive role for adaptations to interval training. Yet, no study has, to date, measured the % of VO2max during all interval sessions throughout a prolonged training intervention and subsequently related it to the magnitude of training adaptations. Thus, the present study aimed to investigate the relationship between % of VO2max achieved during an interval training intervention and changes in endurance performance and its physiological determinants in well-trained cyclists. Twenty-two cyclists (VO2max 67.1 (6.4) mL·min−1 ·kg−1; males, n = 19; females, n = 3) underwent a 9-week interval training intervention, consisting 21 sessions of 5 × 8-min intervals conducted at their 40-min highest sustainable mean power output (PO). Oxygen uptake was measured during all interval sessions, and the relationship between % of VO2max during work intervals and training adaptations were investigated using linear regression. A performance index was calculated from several performance measures. With higher % of VO2max during work intervals, greater improvements were observed for maximal PO during the VO2max test (R2adjusted = 0.44, p = 0.009), PO at 4 mmol·L−1 [blood lactate] (R2adjusted = 0.25, p = 0.035), the performance index (R2adjusted = 0.36, p = 0.013), and VO2max (R2adjusted = 0.54, p = 0.029). Other measures, such as % of maximal heart rate, were related to fewer outcome variables and exhibited poorer session-to-session repeatability compared to % of VO2max. In conclusion, improvements in endurance measures were positively related to the % of VO2max achieved during interval training. Percentage of VO2max was the measure that best reflected the magnitude of training adaptations.

A microcycle of high-intensity short-interval sessions induces improvements in indicators of endurance performance compared to regular training. European Journal of Sport Science (EJSS).

  The purpose of this study was to evaluate the effects of a microcycle of high-intensity interval training (HIT) sessions with multiple short work intervals followed by an active recovery period, compared to a similar duration of regular training, on determinants and indicators of endurance performance in well-trained cyclists. The participants in the BLOCK group performed a 6-day HIT microcycle including five HIT sessions (5 × 8.75-min 30/15 s short intervals) followed by a 6-day active recovery period with reduced training load, while the regular training group (REG) performed 12 days of their regular training, including four HIT sessions. Physiological testing was performed before and after the training periods. From pre- to post- intervention, BLOCK demonstrated significantly larger improvements than REG in mean power output (PO) during the last min of the maximal oxygen uptake (VO2max) test (POVO2max) (3.7 vs. 0.7%, p = 0.009, and effect size (ES) = 1.00) and mean PO during the 10-s sprint (2.8 vs. 1.9%, p = 0.028, and ES = 0.63). No significant differences between BLOCK and REG were observed for VO2max, PO at 4 mmol·L−1 [blood lactate] (PO4mmol), 15-min maximal mean power output (PO15-min), and gross efficiency (p = 0.156–0.919). However, there was a tendency for larger improvements in the performance index (calculated from the main performance indicators POVO2max, PO4mmol, and PO15-min) in BLOCK compared to REG (2.9% vs. 1.2%, p = 0.079, and ES = 0.71). A 6-day high-intensity short-interval microcycle followed by a 6-day active recovery period induces improvements in endurance performance indicators compared to regular training, demonstrating its potential as an efficient strategy for endurance training in well-trained cyclists.

  Blokkperiodisering av utholdenhetstrening, altså at man i korte tidsperioder fokuserer på å forbedre noen få egenskaper av gangen, har det siste tiåret fått stor oppmerksomhet. Det er imidlertid forsket nesten utelukkende på blokktrening av høyintensive treningsøkter (HIT), og det mangler kunnskap om effektene ved blokklegging av moderatintensiv trening (MIT), altså trening på en intensitet rett under den anaerobe terskelen («terskeltrening»). Det mangler også kunnskap om hvor repeterbare effektene av en slik treningsperiode er for den enkelte idrettsutøver hvis en helt lik treningsperiode gjentas på et senere tidspunkt. Forskningsgruppen Trainome ved Seksjon for helse og treningsfysiologi er i gang med et stort forskningsprosjekt som er verdens første studie innenfor dette spesifikke feltet.
