Effect of Angle of View and Partial Sleep Deprivation on Distance Perception

Abstract

The present study aimed to investigate the effects of intensive effort on egocentric distance perception according to different angles of view after sleep deprivation at the beginning (SDB) or at the end (SDE) of the night and after a normal sleep night (NNS). Ten male students soccer players (age 22.8 ± 1.3 years; body mass 72.0 ± 10.4 kg; body height 180.0 ± 3.0 cm) performed a repeated cycling (RS) exercise (10 × 6 s maximal cycling with 24 s in between) after SDB, SDE, and NNS. They were asked to estimate three distances (i.e. 15, 25, and 35 m) before and after RS from different angles of view [i.e. in front (0 • ) and in side (45 • left and 45 • right)]. For 35 m, distance estimation was better during NNS compared to SDB and SDE for the front and the two side angles either before or after RS (p < 0.05). Concerning 25 m, distance estimation was better after compared to before RS for the front angle during the NNS session (p < 0.05). For 15 m, distance estimation was better during NNS than SDB and SDE for the front and both side angles after RS (p < 0.05). We concluded that partial sleep deprivation negatively affected the estimation of the egocentric distance for the three angles of view either at rest or after RS exercise.

Relationships between Sleep, Athletic and Match Performance, Training Load, and Injuries: A Systematic Review of Soccer Players

“…For clarity, the match analysis included two studies that analyzed load from matches with relationship with sleep [ 31 , 32 ]. Athletic performance included 15 studies that applied different experimental designs through physical tests to analyze its influence on sleep [ 20 , 27 , 28 , 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 , 38 , 39 , 40 , 41 ]. Training load included six studies that observed training effects on sleep [ 42 , 43 , 44 , 45 , 46 , 47 ].…”

“…The most-used instrument to analyze sleep was actimetry, applied in twelve studies [ 8 , 9 , 10 , 17 , 18 , 20 , 33 , 38 , 39 , 40 , 41 , 47 ]. In addition, 25 studies included sleep logs/questionnaires to analyze its quantity and/or quality [ 10 , 17 , 18 , 19 , 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 , 40 , 41 , 42 , 43 , 44 , 45 , 46 , 48 , 49 , 50 , 51 ].…”

“…The methodological assessment and scores can be found in Table 2 . Twenty-seven of the included articles [ 8 , 10 , 17 , 18 , 19 , 20 , 30 , 32 , 33 , 34 , 35 , 36 , 37 , 38 , 39 , 40 , 41 , 42 , 43 , 44 , 45 , 46 , 47 , 48 , 49 , 50 , 51 ] were classified with fair methodological quality, while five [ 9 , 27 , 28 , 29 , 31 ] were classified as good.…”

“…The synthesis of results about sleep and athletic and/or match performance can be found in Table 4 . Fifteen studies had data on athletic and or match performance [ 20 , 27 , 28 , 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 , 38 , 39 , 40 , 41 ]. Sleep restriction was applied in eight studies [ 20 , 27 , 28 , 31 , 37 , 38 , 39 , 40 ].…”

Neophobia in 10 ungulate species—a comparative approach

“…In this study, we aimed to study inter-individual and inter-specific variation in neophobia in ungulates. Ungulates are a largely neglected taxon in comparative psychology, despite their high variation in socio-ecological characteristics, which makes them an ideal candidate to test how specific socio-ecological conditions may favor the emergence of certain traits or behaviors (Caicoya et al in review; see Shultz and Dunbar 2006 ; Schaffer et al 2020 ). In this study, we tested neophobia toward novel objects (see Greenberg 1992 ; Mettke-Hofmann et al 2002 ; Greenberg 2003 ; Brown and Jones 2016 ) by providing ten ungulate species with familiar food, half of which had been positioned close to a novel object.…”
