Purpose: Modeling intermittent work capacity is an exciting development to the critical power model with many possible applications across elite sport. With the Skiba 2 model validated using subelite participants, an adjustment to the model’s recovery rate has been proposed for use in elite cyclists (Bartram adjustment). The team pursuit provides an intermittent supramaximal event with which to validate the modeling of W′ in this population. Methods: Team pursuit data of 6 elite cyclists competing for Australia at a Track World Cup were solved for end W′ values using both the Skiba 2 model and the Bartram adjustment. Each model’s success was evaluated by its ability to approximate end W′ values of 0 kJ, as well as a count of races modeled to within a predetermined error threshold of ±1.840 kJ. Results: On average, using the Skiba 2 model found end W′ values different from zero (P = .007; mean ± 95% confidence limit, –2.7 ± 2.0 kJ), with 3 out of 8 cases ending within the predetermined error threshold. Using the Bartram adjustment on average resulted in end W′ values that were not different from zero (P = .626; mean ± 95% confidence limit, 0.5 ± 2.5 kJ), with 4 out of 8 cases falling within the predetermined error threshold. Conclusions: On average, the Bartram adjustment was an improvement to modeling intermittent work capacity in elite cyclists, with the Skiba 2 model underestimating the rate of W′ recovery. In the specific context of modeling team pursuit races, all models were too variable for effective use; hence, individual recovery rates should be explored beyond population-specific rates.

RESUMOO objetivo central deste artigo é investigar o contrato de trabalho intermitente, institucionalizado a partir da Lei 13.467 de 2017 que ensejou a reforma trabalhista brasileira. Trata-se uma nova modalidade de contratação, desconhecida no Brasil, mas que já vinha sendo difundida em muitas legislações ao longo do globo e ficou conhecida como o contrato de trabalho “zero hora”. Por esta modalidade enquadra-se a prestação de serviços subordinada, mas não contínua, que ocorre com alternância de períodos de execução de serviços e de inatividade e que no Brasil poderá ser realizada independentemente do tipo de atividade do empregado e do empregador, o que tende a facilitar sua generalização. Destarte, se vislumbra conhecer e interpretar criticamente esse novo formato de contratação pelo método jurídico-sociológico, buscando entender os impactos jurídicos, sociais e econômicos dele advindos, sobretudo na tentativa de verificar as possibilidades de adequação desse tipo de contrato às bases principiológicas do Direito do Trabalho e às novas conformações de trabalho experimentadas nos últimos anos. Tenta-se na presente investigação empreender verdadeira trincheira hermenêutica em prol de uma contrarreforma, objetivando engendrar práticas laborais juridicamente sustentáveis. Em conclusão, aventa-se a possibilidade de incidência desse contrato ao modelo Uber de serviços, destacando-se a importância desse exercício hermenêutico de resistência, a fim de que a reforma trabalhista seja palco de novas possibilidades de proteção dos trabalhadores.PALAVRAS-CHAVETrabalho Intermitente.

Uber.ABSTRACTThe main objective of this paper is to investigate the intermittent work contract, institutionalized in the Act 13.467 of 2017 that led to the Brazilian labor reform. This is a new modality of hiring, unknown not Brazil, but it is already being spread in many acts throughout the globe and became known as the "zero hour" work contract. This modality includes the provision of subordinate services, but not continuous, which occurs with the alternation of periods of service execution and inactivity, and that in Brazil will be performed independently of the type of activity of the employee and the employer, which tends to facilitate its generalization. Therefore, it is envisaged to know and interpret critically this new format of contracting by the legal-sociological method, seeking to understand the legal, social and economic impacts of it, especially in the attempt to verify the possibilities of adequacy of this type of contract to the foundational bases of the Labor Law and the new working scenario experienced in recent years. In the present investigation it is attempted to embark on a true hermeneutic trench in favor of a counter-reform, with the aim of produce legally sustainable labor practices. In conclusion, it's rising the possibility of incidence of this contract made like the Uber model of services, highlighting the importance of this hermeneutic exercise of resistance, so that the labor reform can be an arena of new possibilities of protection of workers. KEYWORDSIntermittent Work.
