“…High-intensity training (HIT) is a common form of training, which can be performed indoor. The use of HIT has been suggested to be effective as much as long-lasting endurance exercise in promoting cardiovascular health [ 1 ], as well as to improve athletic performance even in trained runners [ 2 , 3 ]. HIT has been suggested to improve muscle power [ 3 ], running economy [ 2 ], mitochondrial content, respiratory capacity [ 4 ], and cardiorespiratory function [ 2 , 3 ].…”

Purpose The COVID-19 restrictions have limited outdoor physical activities. High-intensity training (HIT) may be a valid indoor alternative. We tested whether an indoor HIT is effective in maintaining vascular function and exercise performance in runners who reduce their usual endurance training, and whether a downhill HIT is as effective as an uphill one for such purposes. Methods Sixteen runners performed the same 6-week HIT either uphill (UP, eight runners) or downhill (DOWN, eight runners). Eight runners continuing their usual endurance training acted as a control group (CON). The following data were collected before vs after our HIT: vascular conductance during rapid leg vasodilation to assess vasodilation capacity; V̇O 2max through running incremental test to exhaustion; 2000 m running time; neuromuscular indexes related to lower-limb muscle strength. Results Both uphill and downhill HIT failed in maintaining the pre-HIT leg vasodilation capacity compared to CON, which was, however, blunted more after uphill than downhill HIT. V̇O 2max and 2000 m time were similar after downhill HIT compared to CON, and augmented after uphill HIT compared to CON and DOWN. Indexes of lower-limb muscle strength were similar before vs after HIT and among groups. Conclusion Our HIT was ineffective in maintaining the pre-HIT leg vasodilation capacity compared to runners continuing their usual low-intensity endurance training, but did not lead to reductions in V̇O 2max , 2000 m time performance, and indexes related to lower-limb muscle strength. Our data show an appealing potential for preserving exercise performance with low cardiorespiratory effort via downhill running.

IntroductionRecent immigrants from racialized minority backgrounds and those who are not proficient in the local language are some of the most vulnerable members of society. Despite having postsecondary educational qualifications and permanent residency status, many are engaged in precarious employment. There is a scarcity of research that has explicitly focused on the work experiences and mental health challenges faced by these immigrants.MethodsUsing a grounded theory approach and semi-structured face-to-face interviews, this study examined the work experiences and mental health challenges of 42 recent immigrant employees from two cities in Canada who were working in various industries and engaged in precarious employment.FindingsEighty-one percent of the employee participants were overqualified for their jobs. Findings highlighted several ongoing mental problems that participants experienced, stemming from challenging physical and psychological workplace conditions, negative mindsets associated with their recent immigrant status, and other contextual factors and barriers. However, various coping strategies, both constructive and unconstructive, were used to address this mental distress.DiscussionThe study proposes a multidimensional approach to address workplace conditions to promote good mental health for these employees. This includes preventative programs for raising awareness among employers about the importance of recent immigrant employees’ mental health and well-being and policy and legislation changes to ensure the employer’s commitment to creating a safe and culturally friendly workplace. The approach also recommends that recent immigrant employees receive occupational health and safety training, learn about Canadian workplace norms and culture, and have access to professional healthcare services.
