This study investigated the influence of grip strength on semi‐automatic handguns in basic law enforcement training. The grip strength and marksmanship scores of police recruits were measured. All the recruits underwent the same basic firearms training and about half the recruits were given a Grip Master to exercise with in the hope of improving their grip strength. The grip strength improvement was similar for recruits with and without Grip Master. Both groups significantly improved their marksmanship by the end of the training (97.46 to 113.48 for the Grip Master group, and 92.68 to 112.24 for the control group). The women’s scores were significantly lower than the men’s both at the beginning and at the end of the training (102.6 vs. 114.6 for females and males, respectively at the end of the training). This difference in scores appears to be due to a difference in grip strength. The influence of grip strength on marksmanship scores was small but constant throughout the grip strength range of the police recruits.

This study aims to test the effects of Celliant armbands on grip strength in subjects with chronic wrist and elbow pain. Celliant® is a functional textile fabric containing minerals that emit infrared radiation (IR) in response to body heat. IR-emitting fabrics have biological effects including the reduction of pain and inflammation and the stimulation of muscle function.

A randomized placebo-controlled trial recruited 80 subjects (40 per group) with a six-month history of chronic wrist or elbow pain (carpal tunnel syndrome, epicondylitis or arthritis) to wear an armband (real Celliant or placebo fabric) on the affected wrist or elbow for two weeks. Grip strength was measured by a dynamometer before and after the two-week study.

For the placebo group, the mean grip strength increased from 47.95 ± 25.14 (baseline) to 51.69 ± 27.35 (final), whereas for the Celliant group, it increased from 46.3 ± 22.02 to 54.1 ± 25.97. The mean per cent increase over the two weeks was +7.8% for placebo and +16.8% for Celliant (p = 0.0372). No adverse effects was observed.

Limitations include the wide variation in grip strength in the participants at baseline measurement, which meant that only the percentage increase between baseline and final measurements showed a significant difference. Moreover, no subjective measurements of pain or objective neurophysiology testes was done.

Celliant armbands are easy to wear and have not been shown to produce any adverse effects. Therefore, there appears to be no barrier to prevent widespread uptake.

IR-emitting textiles have been studied for their beneficial effects, both in patients diagnosed with various disorders and also in healthy volunteers for health and wellness purposes. Although there are many types of textile technology that might be used to produce IR-emitting fabrics, including coating of the fabric with a printed layer of ceramic material, incorporating discs of mineral into the garment, the authors feel that incorporating ceramic particles into the polymer fibers from which the fabric is woven is likely to be the most efficient way of achieving the goal.

Celliant armbands appear to be effective in painful upper limb inflammatory disorders, and further studies are warranted. The mechanism of action is not completely understood, but the hypothesis that the emitted IR radiation is absorbed by nanostructured intracellular water provides some theoretical justification.

Selecting the right people for police work is not only important for the employer, but is also in the best interest of the public. Failure to screen out individuals who cannot perform the physical duties has a large human and economic cost. The present study investigated whether physical performance and anthropometric measures can predict recruits’ handgun marksmanship. While significant correlations were found between handgun marksmanship and dominant grip strength, combined grip strength, forearm girth and second ray length, significance was only found when the genders were analyzed together. A step‐wise multiple regression could not generate an equation to predict shooting score from the available data.

The Police Training Institute at the University of Illinois designed a fitness training programme which allowed the participants to choose the intensity and mode of their exercise. Between June 1993 and March 1995, the incoming recruits’ fitness level was assessed before and after the training programme in order to measure the improvement induced by the training and to compare the recruits’ fitness level to the general population. The recruits significantly improved their flexibility (19.10 vs 15.13 degrees) and abdominal strength (4.91 vs 4.98 Lovett score). The male recruits improved their aerobic capacity (recovery heart rate: 86.27 vs 81.32 bpm) and the female recruits improved their back strength (4.86 vs 4.97 Lovett score). No significant changes were observed for grip strength (54.62 vs 54.21 kg), relative body fat (19.5 vs 18.5 per cent body fat), blood pressure (diastolic: 77.99 vs 77.52 mm Hg; systolic: 125.47 vs 125.10 mm Hg), and resting heart rate (74.89 vs 74.23 bpm). Compared to population norms, the majority of the recruits were within the normal range for blood pressure, resting heart rate, abdominal and back muscle strength. A large proportion of the recruits had good flexibility, average grip strength, and fair to excellent per cent body fat. Still, 33.4 per cent of the males and 25 per cent of the females were low to very low in aerobic capacity. As a result, the fitness programme has been modified in order to further improve recruits’ fitness.

Endeavours to determine the physiological and perceptual responses to forearm cold water immersion as influenced by the use of an experimental fireproof carbonaceous insulation (ECI), Thinsulate (a commercial insulation), and Nomex flight gloves. The primary objective was to determine if ECI could provide adequate protection from cold water immersion while providing superior protection from fire. Physiological responses including rectal and skin temperatures to –1 degree C water were recorded. Perceptions of thermal discomfort and grip strength were also measured. The experimental carbonaceous insulation was able to provide better thermal protection as evidenced by significantly higher skin temperatures than the Thinsulate. Subjects perceived the Thinsulate gloves to be only slightly more comfortable than the ECI gloves. Both ECI and Thinsulate provided negligible loss of grip strength. The Nomex gloves provided virtually no thermal protection and substantial loss of grip strength post‐immersion.

The aims of this study were to evaluate fitness levels in a cohort of police trainees and compare these results to other police trainees and the general population.

Retrospective data for 274 male and 152 female police trainees were supplied. Measures included height, body mass and physical appraisal test (PAT; 2.4 km run, vertical jump, push-ups and grip strength) results, assessed twice, prior to commencement of training, separated by several months. Wilcoxon signed rank tests were used to analyze non-parametric initial and final PAT scores and Mann–Whiney U tests were used to determine variance between groups.

Male trainees were significantly quicker in the run (−12%, p < 0.001), completed more push-ups (+74%, p < 0.001) with greater grip strength (+52% left and +50% right, p < 0.001) when compared to female trainees. Following the second PAT assessment, the significant differences between male and female trainees remained (p < 0.001). Only female trainee 2.4 km run times improved significantly between initial and final PAT (−4%, p = 0.002).

When compared to the general population from which they were drawn and to other law enforcement trainees, the police trainees in this study were quicker, more powerful and stronger. While there was no loss of fitness between initial and final PAT performance, a conditioning program, spanning the periods between initial and final PAT may be of benefit to increase fitness prior to training commencement especially for female trainees who were generally less fit than, yet must complete the same training as, male trainees.

The purpose of this paper is to gain an in-depth understanding into the research progress, hot spots and future trends in smart gripping technology in the field of apparel smart manufacturing.

This work scrutinised the current research status of the five automatic grasping methods for garment fabrics including the pneumatic suction grasping, the electrostatic grasping, the intrusive grasping and the dexterous grasping. Specifically, the principles, characteristics, main devices and the impact on garment production were discussed.

In particular, soft finger of the dexterous grasping method has good flexibility and adaptability in the process of fabric grasping, which provides a new solution for garment production automation. Up to now, the reviewed method in general exhibit good grasping speed, high grasping stability and flat grasping process. However, in the face of complex fabric materials which are thin and flexible and do not return their original shapes when deformed in practical applications, the gripper for automatic fabric grasping need new technological breakthroughs in the positioning accuracy, grab efficiency and flexible grasping.

The outcomes offered an overview of the research status and future trends of the automatic grasping methods for garment fabrics in the field of apparel intelligent manufacturing. It could not only provide scholars with convenience in identifying research hot spots and building potential cooperation in the follow-up research but also assist beginners in searching core scholars and literature of great significance.

The purpose of this study is to investigate the relationship between selected physical-physiological parameters and efficiency of pistol shooting.

In all, 237 male volunteers, studying at a Turkish Police Academy within the age range of 19-20 years old were investigated. The physical fitness levels were evaluated by valid and reliable test batteries. The efficiency of pistol shooting was evaluated by the total points of the bullets which hit the target from 10 m.

Significant differences were found between the sets of students according to shot accuracy groups for wrist circumference, biceps circumference, femur diameter, hand grip strength, flexibility, aerobic capacity, reaction time, balance, coordination, state anxiety level, anxiety variability, average heart rate, maximal heart rate and heart rate changes. The correlation coefficient between the pistol shooting result and change in heart rate, anxiety variability, mean heart rate during shooting, coordination, state anxiety, maximal heart rate during shooting, balance, hand-grip strength, biceps circumference, femur diameter, wrist circumference and flexibility was significant.

This research identified parameters which were important in profiling a good shooter. In addition, this result could be used for choosing marksmen and guiding shooting training for athletes and police in which shooting skills are important. It was reported that joining simple field physical fitness tests and simple devices such as heart rate polar meters may have an advantage in selecting good shooters. These would save police departments both time and money.

This is the most comprehensive study to date which has evaluated physical fitness in relation to shooting efficiency.

Breast-cancer-related lymphedema (BCRL) is a negative condition that affects biopsychosocial aspects of patients treated with breast cancer. Yoga has been reported as one of the complementary and alternative approaches used by patients diagnosed with BCRL. The aim of this systematic review was to explore the effectiveness of yoga on BCRL.

A systematic literature was performed by searching existing papers from the electronic scientific databases. Five papers were exclusively examined. Four studies were conducted in women with BCRL, and one study was conducted with women at risk for BCRL.

Four types of yoga were evaluated in relationship with BCRL, namely: the Satyananda Yoga tradition, the modified Hatha yoga, the aerobic yoga training and the Ashtanga-based yoga practices. Four of five included studies reported that decrease in arm volume was not reported for all yoga-type interventions. One study showed no significant evidence that yoga was associated with limb volume change in women at risk of BCRL. Similarly, three studies reported that the change-of-arm-volume measures were not significantly different between the yoga and the control groups or in the same group before and after the yoga program. One quasi-experimental study reported arm volume significantly decreased after attending the yoga program.

This review reported the importance of being aware that yoga is not shown to be an effective strategy for managing or preventing BCRL. However, quality of research methodology, small sample sizes and the limited number of related studies should be acknowledged. Until more rigorous studies are performed, yoga may continue to be used as a complement to traditional therapy under the supervision of certified trainers.

Prenatal exposure to adverse conditions is known to affect health throughout the life span. It has also been shown that health is unevenly distributed at advanced ages. This chapter investigates whether health inequalities at old age may be partially caused by prenatal circumstances. We use a sample of people aged 71–91 from eight European countries and assess how shocks in GDP that occurred while the respondents were still in utero affect four important dimensions of later-life health: cognition, depression, functional limitations, and grip strength. We find that early-life macro-economic circumstances do not affect health at advanced ages, nor do they affect inequalities in health. In additional analyses, we show that the least healthy people may not enter our sample as the probability of dying before reaching age 71 is high, and mortality rates among those who were prenatally exposed to adverse GDP shocks are higher. We conclude that selective mortality may mask effects of early-life circumstances on health and health inequality at old age.
