“…Napping is a recovery period defined as a propensity to sleep in response to the post lunch dip process, which was associated with reductions in core temperature and vigilance and an increase in the tendency to sleep [6]. More importantly, sleepiness [7,8], mood states [9], psychomotor [10], cognitive [7,9,11], and physical performances [11][12][13][14][15][16] have been positively associated with napping. Following a normal night sleep, it has been shown that (i) a 25-min nap opportunity enhanced performance during the 5-m shuttle run test (5mSRT) [12], (ii) a 25-min, 35-min and 45-min nap opportunity decreased subjective fatigue, sleep, and stress [11] and increased physical performance during the 5mSRT [13], (iii) a 35-min and 45-min nap opportunity enhanced 5 jump performance [11], and (iv) a 45-min [11] and 90-min [10] nap opportunity improved attention estimated by the digit cancelation test (DCT).…”

“…After a normal night's sleep, Boukhris et al [13] demonstrated that a 45-min nap opportunity was the best duration, i.e., compared to a 25-min and a 35-min nap, for enhancing performance and reducing fatigue during the 5-m shuttle run test (5mSRT). Furthermore, Hsouna et al [11] showed napping between 35-min and 45-min was more effective than 25-min for improving physical performance and alertness. Although these studies portray the importance of nap opportunities on performance, it is still unknown if an increase in nap duration over 45-min would result in further performance improvements.…”

“…Additionally, a comparison between these two nap opportunities durations (i.e., 40-min vs. 90-min) was examined in the current study. These two durations (i.e., 40-min vs. 90-min) of nap opportunities were chosen in the present study because, based on previous studies, the longest nap duration was 90-min in the studies of Hammouda et al [15] and Romdhani et al [17]; whereas the longest ones in the study of Boukhris et al [13] and Hsouna et al [11] were only 45-min. We hypothesized that both nap durations would prove beneficial and a greater improvement in attention, physical performance, PRS, and reduction in sleepiness, DOMS, and RPE would be observed after a 90-min nap (N90), compared to a 40-min nap (N40) and no-nap (N0) condition.…”

This study examined the effects of different nap durations on attention and physical performance as well as mood states, sleepiness, perceived exertion (RPE), recovery (PRS), and muscle soreness (DOMS) in trained men. Fourteen amateur team sport players (age: 20.3 ± 3.0 years, height: 173.1 ± 6.7 cm, body-mass: 68.1 ± 6.6 kg) performed a maximal voluntary isometric contraction (MVIC) test, 5-m shuttle run, and the digit-cancellation (i.e., attention) test after a no-nap (N0) and 40-min (N40) and 90-min (N90) of nap opportunities. Subjective measurement of mood states, RPE, PRS and DOMS were determined. Compared to N0, both nap durations enhanced attention, MVIC, total distance (TD), and higher distance (HD) (p < 0.001), with a higher gain after N90 compared to N40 for attention (Δ = +3), MVIC (Δ = +30 N) and TD (Δ = +35 m) (p < 0.001). Total mood scores were better after N40 and N90 compared to N0 (p < 0.05), with lower scores after N90 compared to N40 (p < 0.05). DOMS and RPE scores were significantly lower and PRS was significantly higher after N40 and N90 compared to N0 and after N90 compared to N40 (p < 0.05). Although both nap opportunity durations were beneficial, N90 was better than N40 for improving physical performances and attention as well as the perception of recovery, reducing fatigue perception, muscle soreness, and negative mood states.

“…VO 2 max may be considered an indicator of cardiorespiratory fitness, and the use of this method would allow for the determination of this variable's effect in these individuals. Also, changes in dietary habits and sleep could affect the physical fitness [37][38][39], and future studies should record these parameters. Indeed, the observed reduction in weight might not be related only to exercise intervention for both groups.…”

We investigated the effect of exergames and aquatic exercises on lung function and weight loss in obese children. Sixty-one obese male primary-school children were randomly allocated to video game, aquatic exercise, and control groups. Lung functions and anthropometric variables were measured before and after the intervention and after one month (follow-up). In the video game group, an Xbox Kinect game was played for 60 min during three sessions a week. The aquatic aerobic exercise was performed three times per week and consisted of a warm-up, main exercises, and a cool down phase. For the video game group, there was a significant reduction in body weight between (i) pre- and (ii) post-intervention and follow-up. In the aquatic exercise group, there was a significant reduction in body weight between pre- and post-intervention and between pre-intervention and follow-up. Both exercise groups improved the waist/hip ratio index compared to the control group. Forced vital capacity was significantly improved in the follow-up of the video game group and the aquatic exercise group compared to the control group. A significant improvement was found in forced expiratory volume in the first second at post-intervention and follow-up in the video game and the aquatic exercise groups. Exergames and aquatic exercises improved weight loss and lung function in obese children.

“…In fact, previous to any competition or game, the soccer player's sleeping period could be reduced or fragmented by anxiety or jet lag, which is considered as one of the main causes of sleep disruption (Davenne, 2009;Edwards and Waterhouse, 2009); due to that, many strategies [e.g. nap Boukhris et al, 2019a;Chtourou et al, 2019;Hsouna et al, 2019), caffeine ingestion (Souissi et al, , 2015] have been proposed to overcome the negative effect of poor sleep. Jet lag is the term applied to a group of symptoms that exist transiently after undergoing a rapid time-zone transition.…”

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.
