- Description: The primary aim of this study was to compare the effect of a standardised versus customised high-intensity interval training programmeon performance indicators of endurance trained male cyclists utilising a standardised method of prescribing intervals in comparison to a customised method of prescribing intervals based on training feedback. The study was exploratory and quasi-experimental in nature and utilized a quantitative approach. A quasi-experimental, pretest-postestcontrol group study design was used. A total number of 22 participants that met the inclusion criteria were included in the study by means of purposive sampling. The participants were subdivided into an experimental group (n=11) and a control group (n=11)by means of random stratification in order to ensure performance equality between the two groups. The experimental group completed a High-Intensity Interval Training (HIIT) block of 28 days (four weeks) with three weeks of interval-based sessions and one recovery week ending off the block. The programmeutilised the same “anaerobic” type intervals (10 x 30 seconds at 170% PPO with 4 minutes 30 seconds recovery) as the control group, performed twice per week for three consecutive weeks. The Lamberts and Lambert submaximal cycling test (LSCT) was used to determine whether a participant in the experimental group could start his HIIT session on a particular day.Participants were notallowed to start their HIIT session if twoor more of the set criteria weremet.If the participants did not qualify to participate in a HIIT session they were required to perform a low intensity training session in the same venue. Differences between the pre-and post-test showed statistically non-significant improvements (p>0.05) from pre-to post-test for both the experimental and control groups in respect of the physiological variables measured (gas exchange threshold, respiratory compensation point, maximal oxygen consumption). The experimental group did however show more positive, but statistically non-significantimprovements in peak power output. The findings of this study therefore showed that no significant within group nor between group improvements were achieved utilizing a standised versus customised HIIT training programme over the four-week study period. The findings do however suggest that the LSCT may have merit in prescribing HIIT sessions in trained athletesas suggested by the improvements of the experimental group’s peak power output.

- Description: HIV/AIDS has affected families in a profound and tragic way. Children whose parents have succumbed due to HIV/AIDS related infections have to be cared for by their relatives. This study focused on the experiences of primary caregivers of adolescents who are living with HIV in a semi-rural area of Eastern Cape Province, Grahamstown. There is a dearth of literature that is addressing the well-being, experiences and challenges of primary caregivers of adolescents living with HIV. Adolescence is a complex life stage during which adolescents usually present challenging behaviours and are grappling with moral issues. Caregiving to these youngsters who are burdened with HIV infection places additional demands on caregivers, especially so when they are experiencing poverty and poor social and welfare support. A qualitative study was most appropriate to explore and describe the experiences of adolescents infected with HIV. The population of this study was the primary caregivers of adolescents caring for adolescents with HIV in the area of Grahamstown, who are between 11 to 19 years old. A purposive sample of nine primary caregivers of adolescents living with HIV was selected. Data was collected by conducting individual interviews, using a semi-structured interview schedule. Data was analysed thematically according to prescribed theoretical guidelines. Data was verified by means of guidelines for the truth value, applicability, consistency, and neutrality of the study. The findings of the study indicated that primary caregivers experience that caring for adolescents who are living with HIV places a huge burden due to adolescents' negative behaviour, HIV stigma and discrimination, poor support from their families, being confronted with adolescents' emotional issues that they are not capacitated to deal with, and no adequate community resources to assist them. The challenges primary caregivers experience lead to negative effects on their health status. The findings of the study could be useful for informing intervention programmes that are targeting this group and policy development, and implementation of programmes benefiting both infected adolescents and their primary caregivers.
