Long-haul transmeridian travel is a frequent requirement for athletes competing at the highest level. 1 , 2 Such travel can lead to the deleterious, combined effects of travel fatigue and jet lag which typically require 1 day per time zone crossed east and half a day per time zone crossed west to

Domestic and international travel is a common component of an elite athlete’s yearly plan. Track-and-field athletes may travel to weekly competition in different countries during the main season (e.g., Diamond League), whereas distance runners and race walkers may complete less frequently in race

Since the early 1990s, inquiry into travel associated with physical activity has grown from disconnected research on sporting activities attached to vacations to a robust body of knowledge on purposeful trips driven by the desire to actively participate in a sporting activity, known as active sport

( Angevaren et al., 2007 ). Although LTPA is beneficial for improving a variety of health outcomes, it is less clear whether non-LTPA offers similar benefits. One type of non-LTPA is known as active travel , generally described as walking or cycling to and from places for 10 or more minutes. Although active

Currently, it is established that even low-intensity activities, such as travel-related walking and cycling, contribute to maintaining health and functioning in older adults ( Varma et al., 2014 ). With age, participation in sports and exercise declines, while the relative contribution of time and

The interrelated impact of travel-induced fatigue and jet lag symptoms can negatively affect cognitive and physical performance following long-haul transmeridian air travel and is of concern for athletic populations. 1 – 3 Conditions encountered during travel, such as the uncomfortable seating

In the short term, daily smartphone use may decrease daily travel by substituting some utilitarian travels. Smartphone use makes it

Rugby sevens is one of the most physically demanding team sports due to both the intensity of match play and the short recovery times afforded between matches. 1 , 2 At the elite level, this physical challenge is exacerbated by fatigue from travel. 3 The male HSBC World Series consists of 5

Purpose:

To assess the effects of a change in training environment on the sleep characteristics of elite Australian Rules football (AF) players.

Methods:

In an observational crossover trial, 19 elite AF players had time in bed (TIB), total sleep time (TST), sleep efficiency (SE), and wake after sleep onset (WASO) assessed using wristwatch activity devices and subjective sleep diaries across 8-d home and camp periods. Repeated-measures ANOVA determined mean differences in sleep, training load (session rating of perceived exertion [RPE]), and environment. Pearson product–moment correlations, controlling for repeated observations on individuals, were used to assess the relationship between changes in sleep characteristics at home and camp. Cohen effect sizes (d) were calculated using individual means.

Results:

On camp TIB (+34 min) and WASO (+26 min) increased compared with home. However, TST was similar between home and camp, significantly reducing camp SE (–5.82%). Individually, there were strong negative correlations for TIB and WASO (r = -.75 and r = -.72, respectively) and a moderate negative correlation for SE (r = -.46) between home and relative changes on camp. Camp increased the relationship between individual s-RPE variation and TST variation compared with home (increased load r = -.367 vs .051, reduced load r = .319 vs –.033, camp vs home respectively).

Conclusions:

Camp compromised sleep quality due to significantly increased TIB without increased TST. Individually, AF players with higher home SE experienced greater reductions in SE on camp. Together, this emphasizes the importance of individualized interventions for elite team-sport athletes when traveling and/or changing environments.

Today’s lightweight notebook and tablet computers employ thinner keyboards than earlier models. These designs must sacrifice key travel distance as evidenced by new devices with key travel distances lying outside the current 1.5- to 6.0-mm standards. 1 For example, the Microsoft Surface Pro 4’s
