TL;DR: In this paper, the effect of the increased body temperature on the performance of maximum work, viz. a work of short duration (12 to 15 seconds) and a work performance lasting 4 to 5 minutes, was studied.
Abstract: Summary.
It is a well established fact that the body temperature increases during muscular exercise, and that the increase is regulated (NIELSEN, 1938). It was the purpose of this paper to study the effect of the increased body temperature on the performance of maximum work, viz. a work performance of short duration (12 to 15 seconds) and a work performance lasting 4 to 5 minutes. The effect on a peak effort (a “push” or a “pull”) was also studied.
The experiments showed:
1) A given amount of work could be performed better – i. e. in a shorter time – when the organism was warmed up by a preliminary work. Also a greater muscular tension could be developed when “warmed up” than when not.
2) A passive warming up – e. g. by means of radio diathermy or by hot baths – also increased the capacity for work.
3) Massage had no beneficial effect on the performance.
4) The harder the preliminary work was, the higher rose the temperature and the better was the performance (only demonstrated in the work of shorter duration (12 to 15 sec.)).
5) The increased ability to perform hard work is closely correlated to the temperature of the working muscles.
6) The maximum oxygen uptake is slightly higher when the organism is warmed up than when this is not the case, but the oxygen necessary for a certain amount of work is reduced.
From these results it is concluded that a higher temperature in the muscles benefits the ability to perform work by accelerating the chemical processes in the muscles, probably also by decreasing the intramuscular viscous resistance. The accurately regulated higher rectal temperature in work (NIELSEN) allows the muscles to obtain a higher temperature during work than would otherwise be possible.

TL;DR: There is insufficient evidence to endorse or discontinue routine warm-up prior to physical activity to prevent injury among sports participants, however, the weight of evidence is in favour of a decreased risk of injury.

TL;DR: IceBreaker is the first technique to employ and leverage the idea of mixing expensive and cheaper nodes to improve both service time and keep-alive cost for serverless functions -- opening up a new research avenue of serverless computing on heterogeneous servers for researchers and practitioners.
Abstract: Serverless computing, an emerging computing model, relies on "warming up" functions prior to its anticipated execution for faster and cost-effective service to users. Unfortunately, warming up functions can be inaccurate and incur prohibitively expensive cost during the warmup period (i.e., keep-alive cost). In this paper, we introduce IceBreaker, a novel technique that reduces the service time and the "keep-alive" cost by composing a system with heterogeneous nodes (costly and cheaper). IceBreaker does so by dynamically determining the cost-effective node type to warm up a function based on the function's time-varying probability of the next invocation. By employing heterogeneity, IceBreaker allows for more number of nodes under the same cost budget and hence, keeps more number of functions warm and reduces the wait time during high load. Our real-system evaluation confirms that IceBreaker reduces the overall keep-alive cost by 45% and execution time by 27% using representative serverless applications and industry-grade workload trace. IceBreaker is the first technique to employ and leverage the idea of mixing expensive and cheaper nodes to improve both service time and keep-alive cost for serverless functions -- opening up a new research avenue of serverless computing on heterogeneous servers for researchers and practitioners.

TL;DR: Findings indicate that joint position appreciation within the knee accommodates physiological changes within the ligaments and muscles after exercise.
Abstract: Background: It is now generally accepted that the ligamentous structures of the knee not only act as mechanical restraints but also have a neurophysiological role in joint function and protection. A report that knee joint laxity increases with exercise raised the question as to whether there is any compensatory change in joint position appreciation. Objective: To test whether there is a compensatory mechanism for increased ligamentous laxity during normal levels of activity. Methods: Joint position appreciation was measured, using a previously reported technique, in the knees of sportsmen at rest and after warm up. Results: Joint position appreciation was found to be significantly more sensitive after warm up (p = 0.005). Conclusions: These findings indicate that joint position appreciation within the knee accommodates physiological changes within the ligaments and muscles after exercise.
